IFX9201SGAUMA1 Overview
An H-bridge motor driver is an integrated power stage built from four switching elements (two high-side and two low-side MOSFETs) arranged in an "H" topology, allowing bidirectional current flow through a DC motor or inductive load. The bridge sits in the broader motor-driver hierarchy between simple logic-level MOSFET half-bridges and fully-isolated three-phase inverter modules used for AC servo drives. Compared with discrete MOSFET implementations, an integrated H-bridge like the IFX9201SG reduces PCB footprint, simplifies fault handling, and provides matched dead-time control across the high-side and low-side switches.
Key features of the IFX9201SGAUMA1 include integrated charge-pump gate drive for 100% duty-cycle operation, programmable current limit, adjustable slew rate via gate-resistor selection, undervoltage lockout, overcurrent shutdown, and overtemperature protection. The SPI interface exposes diagnostic registers for short-circuit, open-load, and thermal-warning flags, enabling predictive maintenance in industrial fieldbus nodes. The device accepts logic-level 3.3 V or 5 V PWM and direction inputs, allowing direct connection to a microcontroller GPIO without level shifters.
The internal architecture uses N-channel MOSFETs on both high-side and low-side positions to minimize RDS(on), driven by an internal charge pump that maintains gate enhancement at low supply voltages. PWM chopping up to 25 kHz is supported for current control or average-voltage regulation, while the SPI block runs up to 4 MHz for fast fault readback.
Typical applications include small brushed-DC motor drives in power tools, home-appliance pumps and valves, building-automation dampers, medical pumps, and battery-management relay drivers. The wide 5 V to 36 V input range covers both 12 V lead-acid and 24 V industrial bus rails.
When designing with this part, place the supply and motor-side bypass capacitors close to the IC and tie the exposed pad to a sufficiently large copper pour to keep junction temperature within ratings at full 6 A continuous current. Use the SPI diagnostics to flag fault conditions to the host MCU rather than relying on software polling of external sense resistors.

Typical Applications
IFX9201SGAUMA1 is suitable for 7 applications: Power Tool Motor Drive, Home Appliance Pump and Valve Control, Building Automation Damper Actuator, Medical Infusion Pump Motor Control, Battery Management Relay Driver, Industrial Fieldbus Motor Node, Robotic Actuator Module.
Power Tool Motor Drive
The IFX9201SGAUMA1 is well-suited for brushed-DC motor control in cordless power tools such as drills, screwdrivers, and small saws. Its 5 V to 36 V supply range covers 18 V and 36 V battery packs common in professional cordless tool platforms, and the 6 A continuous current rating handles the high inrush loads seen at motor startup. The integrated SPI diagnostics allow the tool's microcontroller to detect stalled-rotor conditions and trigger safety shutoff within milliseconds, protecting both the user and the motor windings from damage.
Recommended
Home Appliance Pump and Valve Control
In washing machines, dishwashers, and refrigerator water dispensers, the IFX9201SGAUMA1 drives small DC pumps and solenoid valves with precise PWM speed control. The 25 kHz PWM capability supports quiet operation above the audible range, and the exposed-pad DSO-12 package fits within the compact motor-control modules mounted on the appliance chassis. The device's undervoltage lockout protects the appliance electronics during brownout conditions, while overtemperature protection prevents damage if the pump is mechanically stalled.
Recommended
Building Automation Damper Actuator
HVAC damper actuators in commercial building automation systems use the IFX9201SGAUMA1 to drive small DC gear motors that open and close air-flow valves. The 36 V maximum supply accommodates 24 V industrial bus rails common in building-management systems, and the SPI interface allows central BMS controllers to poll actuator position and fault status. The device's low quiescent current and wide operating temperature range support 24/7 operation in ceiling-mounted actuator housings.
Recommended
Medical Infusion Pump Motor Control
Portable medical infusion pumps require precise, low-speed DC motor control with redundant safety monitoring - a use case well served by the IFX9201SGAUMA1's SPI diagnostics and short-circuit detection. The exposed-pad PG-DSO-12-17 package fits within the compact pump housing, and the device's medical-relevant reliability features (overtemperature shutdown, undervoltage lockout) support IEC 60601-1 system compliance when properly designed. The 6 A continuous rating covers most small peristaltic and syringe-pump motor requirements in ambulatory devices.
Recommended
Battery Management Relay Driver
In 12 V and 24 V battery management systems for industrial and telecom backup applications, the IFX9201SGAUMA1 drives latching relays that disconnect battery strings during fault conditions or maintenance cycles. The 5 V minimum supply allows direct operation from deeply discharged battery packs, and the integrated current limit protects the relay coils from overcurrent damage. The SPI diagnostics enable the battery management controller to verify successful relay state changes by monitoring current feedback.
Recommended
Industrial Fieldbus Motor Node
Decentralized motor-drive nodes on industrial fieldbus networks (PROFIBUS, CANopen, EtherCAT) use the IFX9201SGAUMA1 as the final power stage driving small DC motors in conveyor diverters, sorting arms, and packaging machinery. The SPI interface connects directly to a fieldbus communication controller for bidirectional diagnostic reporting, while the 36 V supply range matches common 24 V industrial rail voltages. The exposed-pad package supports the sustained 6 A operation typical in 24/7 production environments.
Recommended
Robotic Actuator Module
Small robotic actuators in collaborative robots (cobots) and educational robotics platforms use the IFX9201SGAUMA1 to drive joint motors with precise torque control via PWM. The device's 25 kHz PWM frequency enables smooth torque ripple reduction, while the SPI fault register supports predictive maintenance algorithms that flag bearing wear before catastrophic failure. The compact PG-DSO-12-17 package allows integration directly onto actuator PCBAs alongside the position encoder and fieldbus interface.

Design Notes
Estimated: at 6 A continuous load and 24 V supply driving a 12 V motor, the IFX9201SGAUMA1 dissipates approximately (24 V - 12 V) * 6 A = 72 W. With proper PCB layout using the exposed pad tied to at least 6 square centimeters of 2 oz copper, the junction-to-ambient thermal resistance of the PG-DSO-12-17 package allows continuous 6 A operation. Without adequate copper, thermal shutdown will trigger at lower currents. Always verify junction temperature in worst-case load conditions.
Place supply bypass capacitors (10 uF ceramic + 100 nF high-frequency) within 5 mm of the VS pin, and motor output capacitors close to the OUT1 and OUT2 pins. Use wide copper traces (at least 2 mm or 30 mils) for motor current paths to minimize voltage drop and EMI. Connect the exposed pad to a ground pour using multiple thermal vias (at least 9 vias in a 3x3 grid) for efficient heat transfer to internal PCB copper layers.
The IFX9201SGAUMA1 requires logic supply sequencing - the 3.3 V or 5 V logic rails should be stable before VS rises to avoid undefined SPI register states. Do not exceed 36 V on VS even transiently, as the internal MOSFET avalanche rating may be exceeded. Always read the SPI fault register after motor start to detect stalled-rotor conditions, and use the EN pin for safe motor disable during firmware initialization.
PWM chopping at frequencies above 20 kHz keeps switching harmonics above the audible band, reducing acoustic noise in motor applications. For EMI-sensitive designs, add small gate resistors (10-100 ohm) in series with the OUT pins to slow the switching edge and reduce high-frequency emissions. A 100 nF ceramic capacitor across the motor terminals helps suppress conducted EMI on the motor leads.
