BTS70082EPZXUMA1 Overview
A high-side power switch is a semiconductor device that connects a load to the positive supply rail while providing controlled turn-on/turn-off, current limiting, and fault feedback. PROFET devices belong to the broader category of intelligent power switches (IPS), which sit between simple power MOSFETs and fully integrated H-bridge motor drivers. They are commonly used in automotive body electronics to replace mechanical relays and fuses with solid-state switching, enabling PWM-based load control and diagnostic feedback over CAN or LIN networks.
Key features include very low standby current, separate diagnostic feedback for each channel via the IS pin current sense output, reverse battery protection capability with an external resistor, ground-loss detection, and AEC-Q100 qualification for automotive use. The exposed thermal pad reduces junction-to-ambient thermal resistance to 35 C/W, supporting sustained 7.5 A operation on moderate copper area.
Internally, the BTS70082EPZXUMA1 uses a vertical N-channel DMOS process with an embedded charge pump to drive the gate above the battery rail. The integrated current sense delivers a proportional analog current at the IS pin that the microcontroller can digitize with an ADC for load-diagnostics (open load, short circuit, normal operation). Each channel has independent input control, allowing two loads to be driven from one IC.
Typical applications include automotive lighting (headlamp, tail, interior LED), heating elements (PTC heater booster, seat heater), DC motors (window lift, fuel pump, fan), and solenoid/valve drivers. The device is well suited for body control modules and zone ECU designs where two independent high-side channels are needed with full protection.
When designing with this part, keep input pins below 5.5 V even during load-dump transients up to 35 V (a series resistor or TVS is typical), place the sense resistor close to the IS pin to avoid noise pickup, and ensure the exposed pad is soldered to at least 1 cm squared of copper for full current capability. Reverse-battery protection requires an external N-channel MOSFET in the ground return or series resistor on Vbb.

Typical Applications
BTS70082EPZXUMA1 is suitable for 7 applications: Automotive Headlamp and Tail Lighting, PTC Heater Booster and Seat Heater Control, DC Motor Drivers (Window Lift, Fuel Pump, Fan), Solenoid and Valve Drivers, Industrial 24V Load Switching, Body Control Module (BCM) Distributed Outputs, LED Driver Backbone for Interior Lighting.
Automotive Headlamp and Tail Lighting
The BTS70082EPZXUMA1 is ideal for automotive headlamp and tail lighting loads where each channel can drive up to 7.5 A of incandescent, halogen, or LED string current. Its 9 mOhm (typ) Ron keeps conduction loss under 0.5 W at full load, and the integrated diagnostic IS pin reports open-filament or short-circuit conditions to the BCM microcontroller for bulb-out detection on the dashboard. The AEC-Q100 qualification and 35 V load-dump tolerance handle the harsh 12 V automotive electrical environment across -40 C to +125 C ambient.
Recommended
PTC Heater Booster and Seat Heater Control
PTC booster heaters and seat heater mats draw 5-10 A continuous, fitting comfortably within the BTS70082EPZXUMA1's 7.5 A per-channel rating. The exposed thermal pad of the PG-TDSO-14-11 package provides sufficient heat-sinking on standard 1-2 oz copper for sustained operation, and the overtemperature shutdown protects against blocked airflow. Using PWM at 100-200 Hz the BCM can vary seat heater power smoothly from 0 to 100 percent duty cycle without the mechanical wear of relay-based designs.
Recommended
DC Motor Drivers (Window Lift, Fuel Pump, Fan)
The BTS70082EPZXUMA1 drives brushed DC motors up to 7.5 A in window lift, fuel pump, and cooling fan applications where two independent channels handle direction control or dual-motor stacks. With 110 us turn-on and 100 us turn-off times the switch supports PWM at frequencies up to 1 kHz for soft-start and motor speed control. The overcurrent protection auto-restarts after the fault clears, eliminating service calls for nuisance fuse replacement in field-deployed units.
Recommended
Solenoid and Valve Drivers
Automotive transmission solenoids, EVAP purge valves, and emissions control valves typically draw 1-3 A, well within the BTS70082EPZXUMA1's 7.5 A limit. The dual independent channels let one IC drive two valves simultaneously, reducing board area and BOM cost. The current sense output (IS pin) provides closed-loop feedback for adaptive valve control, while the undervoltage lockout prevents inadvertent actuation during cranking events when battery voltage drops below 6 V.
Recommended
Industrial 24V Load Switching
Beyond automotive, the BTS70082EPZXUMA1's 28 V maximum supply voltage makes it suitable for industrial 24 V bus PLC and process-control applications. Drive indicator lamps, small heaters, or relay coils from a single IC with full protection. The exposed-pad SOIC-14 package reflows on standard SMT lines, and the 4.1 V minimum operating voltage provides margin for 24 V bus transients under inductive load switching.
Recommended
Body Control Module (BCM) Distributed Outputs
Modern zone ECUs and BCMs aggregate multiple smart high-side switches to replace fuse boxes. The BTS70082EPZXUMA1 provides two channels per IC with full diagnostics, allowing the BCM to read back load status over CAN or LIN. Multiple BTS70082EPZXUMA1 devices can be paralleled on the same Vbb rail, each addressed by independent logic inputs, building a scalable 8 to 16 channel output stage in less than 10 cm squared of board area.
Recommended
LED Driver Backbone for Interior Lighting
The BTS70082EPZXUMA1 drives interior LED strings up to 7.5 A, supporting ambient lighting, footwell, and dashboard backlighting. Combined with a constant-current LED driver IC, the high-side switch provides on/off control, PWM dimming, and fault detection without adding a discrete MOSFET. The exposed pad keeps junction temperature under 150 C even at full ambient 85 C, ensuring long-term reliability required for OEM interior lighting specifications.

Design Notes
Estimated: at full 7.5 A per channel, dual-channel conduction loss is approximately 2 P = 2 x I^2 x R = 2 x 7.5^2 x 0.009 = 1.01 W. With PG-TDSO-14-11 theta_JA around 35 C/W when the exposed pad is soldered to at least 1 cm squared of copper on a 2-layer board, junction temperature rise above 85 C ambient is roughly 35 C - placing Tj around 120 C, well within the 175 C maximum. For sustained operation at 25 C ambient on a 4-layer board with 4 cm squared of copper, theta_JA drops to approximately 25 C/W and Tj stays below 110 C. Add a thermal via array under the exposed pad to maximize heat transfer.
Place a 100 nF ceramic decoupling capacitor directly at the Vbb pins (8 and 9) within 5 mm of the package, plus a bulk 10-47 uF electrolytic or ceramic nearby. Keep the IS trace short and routed away from switching nodes to avoid noise coupling into the ADC sense signal. The exposed pad must be soldered to a continuous copper plane with at least four thermal vias (0.3 mm drill, 0.5 mm pitch) to the inner Vbb or GND layer for thermal performance per the Infineon application note.
Three common mistakes in BTS70082EPZXUMA1 designs: (1) Forgetting reverse-battery protection - the part alone cannot survive reverse polarity; add an external N-channel MOSFET in the ground return or series resistor on Vbb. (2) Driving the IN pin above 5.5 V even during 35 V load-dump transients - use a series resistor (10 kOhm) and a 5.1 V TVS clamp on IN. (3) Leaving the IS pin floating - the IS pin must have a pull-down resistor to GND (typically 1 kOhm to 4.7 kOhm) or the diagnostic function is undefined. Always tie unused IN pins to GND to prevent floating-state leakage.
Route high-current OUT traces with at least 1 oz copper width to handle 7.5 A continuous (approx 4 mm wide for 10 C rise). Keep the OUT traces short to minimize inductive kick during turn-off, and place a TVS or clamp close to inductive loads to absorb flyback energy. Separate the analog ground (IS return) from the power ground (Vbb return) at the IC and join them at a single star point near the battery negative terminal to prevent ground bounce from corrupting the IS sense signal.
