BTH60702EPVXUMA1 Overview
A high-side switch is a power distribution switch that sits between the supply rail and the load, allowing the load to be turned on/off by a low-voltage control signal while protecting the wiring harness from faults such as over-current, short-circuit, over-voltage, and reverse battery. Within the broader component taxonomy, the BTH60702EPVXUMA1 sits in the smart high-side switch (intelligent power switch, IPS) family, which descends from discrete MOSFETs and power distribution switches and integrates them with logic, sense, and protection in a single device. This integration reduces PCB area, simplifies wiring harness design, and improves diagnostic coverage in body and powertrain ECUs.
Key features include a typical on-state resistance of 60 mΩ per channel, dual independent 1:1 N-channel outputs, current-sense analog feedback for load diagnosis, integrated charge pump for full N-channel drive, and protection against over-load, short-circuit, over-voltage, reverse battery, and thermal shutdown. The PG-TSDSO-14 package with exposed pad provides a low thermal resistance path that sustains 1.7 A continuous per channel in automotive temperature classes.
Typical applications include automotive lighting (headlamps, tail lamps, indicator LEDs), resistive and inductive body loads (seat heaters, mirror heaters, washer pumps), 48 V board-net zonal modules, and zone-ECU power distribution in mild-hybrid and 48 V vehicles. The device's current-sense output also enables predictive maintenance and open-load detection at standstill.
When designing with this part, ensure that the exposed pad is soldered to a sufficiently large copper area (typically 1 cm² or more) to keep junction temperature within the automotive -40 °C to +150 °C range under worst-case load. The IN pins of both channels should be tied to the same supply; if independent supplies are required, two separate BTH6070-2EPV devices must be used.

Safe Operating Area - High-Side Switch
Typical Applications
BTH60702EPVXUMA1 is suitable for 6 applications: 48 V Automotive Lighting, 48 V Body Load Switching (Heaters, Pumps, Mirrors), Mild-Hybrid 48 V Zonal ECU Power Distribution, 48 V Auxiliary Load Switching (Fans, Valves, Actuators), Battery Management Protection (48 V Li-ion Packs), Industrial 48 V Power Distribution.
48 V Automotive Lighting
The BTH60702EPVXUMA1 drives 48 V LED headlamp and tail-lamp modules from a zonal ECU, where its 60 mΩ RDS(on) keeps conduction dissipation to roughly 0.17 W per channel at 1.7 A and its 54 V transient tolerance handles load-dump events on the 48 V rail. Two independent 1:1 channels let one device drive both the low-beam and high-beam LED strings from a single IC, simplifying the harness and reducing PCB area. The integrated analog current-sense output enables open-string and partial-short detection during ECU diagnostics, supporting ASIL-aware functional safety. Compared with a discrete MOSFET + fuse approach, this smart high-side switch consolidates protection, sense, and drive in a single 14-pin PG-TSDSO package.
Recommended
48 V Body Load Switching (Heaters, Pumps, Mirrors)
Resistive and inductive body loads such as seat heaters, mirror heaters, and washer pumps are driven directly by the BTH60702EPVXUMA1 from a 48 V supply. The device's over-load and short-circuit protection allow safe handling of motor stall currents without external fusing, while the current-sense pin reports the actual load current to the body-domain ECU for fault detection and predictive service. The exposed-pad PG-TSDSO-14 package sustains 1.7 A per channel continuously on a typical FR-4 PCB with 1 cm² of copper, fitting the compact form factor of modern zonal modules. Two channels per package reduce BOM count in body ECUs that switch many similar loads.
Recommended
Mild-Hybrid 48 V Zonal ECU Power Distribution
In mild-hybrid 48 V zonal ECU architectures, the BTH60702EPVXUMA1 distributes power from the 48 V bus to multiple downstream loads and downstream converters. Its 54 V maximum supply rating tolerates transient overshoot typical of 48 V board nets under load dump, and its reverse-battery protection eliminates the need for an external reverse-polarity FET. The two independent channels let one IC serve two distinct downstream rails, simplifying the harness and reducing PCB area in space-constrained zonal modules. Current-sense feedback supports ECU-level energy management and load monitoring required by mild-hybrid operating strategies.
Recommended
48 V Auxiliary Load Switching (Fans, Valves, Actuators)
Auxiliary 48 V loads such as cooling fans, solenoid valves, and small actuators in mild-hybrid powertrains are switched by the BTH60702EPVXUMA1. The smart high-side switch handles inrush currents of fans and inductive kickback of solenoids via integrated protection, eliminating external freewheel diodes in many cases. Two channels can drive a fan and a valve from one IC, simplifying PCB layout. The exposed-pad package keeps thermal rise modest at 1.7 A continuous, while the diagnostic current-sense output lets the powertrain ECU detect failing fans or stuck valves. Compared with electromechanical relays, this solid-state solution is silent, faster, and supports PWM-based fan-speed control.
Recommended
Battery Management Protection (48 V Li-ion Packs)
Inside 48 V Li-ion battery management systems, the BTH60702EPVXUMA1 can serve as a high-side disconnect and precharge path element, where its 54 V rating covers the fully charged 48 V pack and its over-voltage clamp protects downstream ASICs. The current-sense pin supports accurate pack-current measurement during precharge and normal operation, while integrated thermal shutdown protects against pack-fault conditions. Two channels can route the main discharge path and a redundant precharge path. The PG-TSDSO-14 footprint suits compact BMS PCBs that integrate with the cell-monitoring ASICs.
Recommended
Industrial 48 V Power Distribution
Beyond automotive, the BTH60702EPVXUMA1 fits industrial 48 V power distribution systems, such as 48 V telecom racks, 48 V solar battery banks, and 48 V robotics buses. Its high-side topology, current-sense output, and protection suite give designers the same diagnostic and protection advantages enjoyed by automotive users, while its 54 V tolerance handles industrial transients. Two independent 1.7 A channels can switch multiple downstream rails from a single IC. The exposed-pad PG-TSDSO-14 package simplifies thermal management in enclosed industrial enclosures with limited airflow.

Key Differentiators
- 48 V board-net native design (vs BTS51202EKAXUMA1)
- Dual 1:1 independent channels in one package (vs BTH60801EPLXUMA1)
- Integrated analog current-sense diagnosis (vs Discrete MOSFET + fuse)
Design Notes
Estimated: at 1.7 A per channel on both channels and VIN = 48 V, conduction loss is approximately 2 × I² × R = 2 × 1.7² × 0.06 = 0.35 W. With a typical PG-TSDSO-14 exposed-pad theta_JA in the 30-40 C/W range on 1 cm² of 1 oz copper, junction temperature rise above ambient is roughly 10-14 °C, well within the 150 °C limit. For higher current or higher ambient, increase copper area or add thermal vias to inner planes. Always validate with a thermal camera on the final assembly.
Solder the exposed pad of the PG-TSDSO-14 to a copper pour of at least 1 cm² to meet thermal and electrical performance. Place the VBB decoupling capacitors (typically 100 nF ceramic + 10 µF electrolytic) within 5 mm of the VBB pins to suppress supply transients from the 48 V board net. Route the high-current OUT traces with wide, short copper pours; minimize loop inductance to keep switching transients within the device's over-voltage clamp window. Keep the IS (current-sense) trace short and away from noisy switching nodes to preserve diagnostic accuracy.
Do not parallel the two channels of one BTH60702EPVXUMA1 to double the current - the channels share thermal paths but have independent current limiting, so imbalance will occur. Do not operate the device without the exposed pad soldered; thermal shutdown will trigger prematurely. Do not connect IN1 and IN2 to different supply rails - both channels share VBB and require common supply. For 12 V designs, consider the BTS51202EKAXUMA1 family instead of using this 48 V part, as the RDS(on) is optimized for 48 V and may be unnecessarily high for 12 V applications.
