BTN9970LVAUMA1 Overview
What is a NovalithIC? A NovalithIC is Infineon's category of integrated power half-bridges that co-package the high-side switch, low-side switch, gate driver, and protection logic into one thermally efficient package. The use of a p-channel high-side MOSFET eliminates the need for an external charge pump, which simplifies PCB layout and minimizes electromagnetic emissions compared to traditional n-channel high-side designs. Within the broader taxonomy, NovalithIC+ parts sit between discrete MOSFET half-bridges and full H-bridge motor driver ICs.
Key features include a 9.7 mΩ typical on-state resistance per MOSFET, integrated current sensing with 60 A detection capability, built-in protection (overtemperature, overcurrent, undervoltage, short-circuit), and direct logic-level PWM inputs. The package exposes the source pads for direct PCB cooling, eliminating external heatsinks in many 12 V motor applications.
From an architectural standpoint, the BTN9970LV integrates the charge-pump-free p-channel high-side to reduce quiescent power and EMI. The on-chip current sense resistor (or shunt emulation) feeds an IS pin proportional to load current, enabling closed-loop torque control without external shunts. Logic inputs are TTL-compatible and accept 3.3 V or 5 V microcontroller signals.
Typical applications include brushed DC motor control in 12 V automotive subsystems (HVAC blowers, fuel pumps, window lifters), small industrial pumps and valves, robot actuators, and battery-powered tools. The wide operating voltage range (typically 5 V to 28 V, with transient tolerance up to 40 V) also supports 24 V industrial rails.
Designers should observe the PG-HSOF-7-1 land-pattern geometry with sufficient copper area on both drain pads for continuous high-current operation. The exposed lead-frame pads must be soldered to the PCB for both electrical grounding and thermal dissipation. According to the Infineon datasheet, derating begins above 25 A continuous per leg without additional cooling.

Typical Applications
BTN9970LVAUMA1 is suitable for 6 applications: Automotive HVAC Blower Motor Drive, Brushed DC Fuel Pump Driver, Power Window Lift Motor Control, Industrial 24V Solenoid and Valve Drivers, Battery-Powered DC Tools and Robotics, Small Pumps and Fans in White Goods.
Automotive HVAC Blower Motor Drive
The BTN9970LVAUMA1's 9.7 mΩ R_DS(on) and 60 A peak current detection make it well-suited for 12 V brushed DC HVAC blower motors in automotive climate-control systems. Placed between the 12 V battery rail and the blower motor, it accepts a 3.3 V or 5 V PWM command from the body control module and modulates motor speed with closed-loop torque control via the IS pin. Compared to a discrete half-bridge, the integrated p-channel high-side eliminates the charge pump, reducing EMI that could interfere with the AM radio band common in HVAC installations. Continuous current is typically limited to 10-15 A in this application, well within the BTN9970LVAUMA1's thermal envelope with proper PCB copper area on the exposed drain pads.
Recommended
Brushed DC Fuel Pump Driver
For 12 V automotive brushed DC fuel pumps drawing up to 15 A continuous, the BTN9970LVAUMA1 provides the necessary current handling in the compact PG-HSOF-7-1 package. The integrated short-circuit and overcurrent protection features are critical for safety in fuel-system applications where a stuck rotor could otherwise draw destructive currents. The IS pin enables closed-loop control of fuel pressure by regulating pump speed in response to engine demand, while the monolithic driver accepts the engine ECU's PWM signal directly. The p-channel high-side architecture eliminates the typical charge-pump switching noise that could otherwise affect sensitive crank-position sensors in adjacent wiring.
Recommended
Power Window Lift Motor Control
Power window lift motors draw 10-20 A peaks during the window travel cycle and must tolerate stall currents without damage. The BTN9970LVAUMA1's integrated short-circuit protection and overtemperature shutdown protect the wiring harness in the event of mechanical blockage. Using two BTN9970LVAUMA1 devices in a full H-bridge configuration provides bidirectional motor control from the body control module. The exposed drain pads dissipate heat directly into the PCB copper, eliminating the heatsink required by discrete MOSFET designs and allowing a compact door-module PCB. The logic-level PWM input connects directly to 3.3 V microcontrollers without level shifters.
Recommended
Industrial 24V Solenoid and Valve Drivers
For 24 V industrial solenoid valves and small actuators, the BTN9970LVAUMA1 operates from a 24 V bus with adequate transient headroom. Its integrated protection features are particularly valuable in industrial environments where inductive kickback from solenoids could otherwise damage discrete MOSFETs. The half-bridge topology pairs with a flyback diode or active clamp to switch DC solenoids; two devices can form a bidirectional proportional valve driver for hydraulic control. Compared to electromechanical relays, the BTN9970LVAUMA1 offers silent operation, longer lifetime (no mechanical wear), and PWM current profiling via the IS pin for soft-start valve actuation.
Recommended
Battery-Powered DC Tools and Robotics
Battery-powered cordless tools (drills, saws, garden tools) using 12-18 V brushed DC motors benefit from the BTN9970LVAUMA1's compact footprint and high efficiency. The 9.7 mΩ R_DS(on) minimizes conduction losses, extending battery runtime per charge cycle. Trigger-input PWM from the tool's microcontroller directly modulates motor speed, while the integrated current sense enables torque limiting for tool protection and stall detection. For two-motor designs (e.g., robotic drive wheels), pairing two BTN9970LVAUMA1 devices creates a complete motor-control solution without external gate drivers or charge pumps, reducing BOM cost and assembly time.
Recommended
Small Pumps and Fans in White Goods
Washing machines, dishwashers, and refrigerator circulation pumps often use brushed DC motors in the 5-20 A range - a sweet spot for the BTN9970LVAUMA1. The integrated protection (overtemperature shutdown) is essential in unattended appliances where motor failure could cause fire hazards. The IS pin enables constant-pressure pump control by adjusting PWM duty cycle based on flow-sensor feedback. The p-channel high-side switch design also eliminates the audible whine that charge-pump switching can produce in consumer products, where acoustic noise is a key design criterion. The PG-HSOF-7-1 package's exposed thermal pads provide sufficient cooling in the enclosed appliance environment.

Key Differentiators
- Lowest R_DS(on) in the NovalithIC+ family at 9.7 mΩ (vs BTN7970B)
- Highest peak current detection at 60 A in PG-HSOF-7-1 footprint (vs BTN7960B)
- P-channel high-side eliminates external charge pump (vs Discrete half-bridge with n-channel high-side)
Design Notes
The PG-HSOF-7-1 package dissipates heat primarily through the exposed drain pads that must be soldered to the PCB copper. For continuous current above 15 A per leg, allocate at least 6 square centimeters of copper on each drain pad (top and inner PCB layers stitched with thermal vias). Estimated: at 12 V supply, 1 A continuous motor current, conduction loss is approximately P = I^2 × R_DS(on) = 1 × 9.7 mΩ ≈ 10 mW per leg, but 25 A continuous produces ~6 W per leg requiring substantial thermal management. Without thermal vias and copper, the junction temperature will exceed 150 C in minutes.
Place a 100 nF ceramic decoupling capacitor as close as possible to the VS pin, with a 10 µF bulk capacitor on the motor supply rail within 10 mm. The OUT trace should be wide enough to handle the peak motor current - use at least 4 mm of copper width per ampere for the motor return path. Star-ground the logic GND and power GND at the BTN9970LVAUMA1 GND pin to prevent switching currents from disturbing logic-level signals.
Do not operate the BTN9970LVAUMA1 without a flyback path on the OUT pin when switching inductive loads - the integrated body diodes handle transient energy, but sustained flyback currents can exceed ratings. For H-bridge configurations using two devices, always insert a dead-time (typically 1-5 µs) between high-side turn-off and low-side turn-on to prevent shoot-through. Verify the PWM input does not exceed the absolute maximum logic voltage of 5.5 V or damage to the input stage may occur.
The p-channel high-side architecture already eliminates the major charge-pump EMI source common to n-channel high-side designs. To further reduce EMI, add a small RC snubber (10 Ω + 10 nF) across the OUT-to-VS path if switching transients exceed automotive EMC requirements. Keep PWM input traces short and route them away from the OUT switching node to minimize capacitive coupling into the logic input.
