BSP772TXUMA1 Übersicht
A high-side power switch (also called a smart high-side switch, high-side load driver, or PROFET) is a semiconductor device that sits between the positive supply rail and the load. Unlike a low-side switch that returns current to ground, a high-side switch allows ground-referenced loads (lamps, solenoids, motors) to be turned on and off without disturbing the load's reference. Smart variants integrate protection and diagnostics; the BSP772TXUMA1 belongs to the Classic PROFET subfamily, sitting within the broader category of power distribution switches -> PMIC -> power management IC -> semiconductor.
Key features include over-current protection, over-voltage clamp, over-temperature shutdown, ESD protection, short-circuit protection, and an open-drain status flag pin for fault feedback to a microcontroller. The integrated charge pump drives the N-channel MOSFET gate, achieving low typical on-state resistance which minimizes conduction losses and thermal stress. The PROFET family is widely adopted in body electronics modules for driving lamps, motors, solenoids, and resistive heaters.
Technically the device combines a vertical N-channel DMOS output stage with CMOS/BCD control logic on a single die. The integrated reverse-battery protection and ground-loss robustness allow direct connection to the 12 V automotive bus without external reverse-polarity components. The 8-pin SOIC with thermal pad (PG-DSO-8-6) provides low thermal resistance for dissipating load current losses in compact PCB areas.
Typical applications include automotive body electronics (interior lighting, door modules, seat controllers), industrial 24 V/12 V load driving, relay replacement, and protected power distribution in PLC and HVAC systems. The device is also used in motorcycle and e-bike ECUs and as a protected USB VBUS switch in automotive head units.
When designing with the BSP772TXUMA1, ensure input capacitance is placed close to the supply pin and that the tab/exposed pad is soldered to a sufficient copper pour for heat dissipation. The status pin requires an external pull-up resistor; the input (IN) pin is TTL/CMOS compatible. Avoid continuous operation at maximum current above 25C ambient unless proper thermal management is applied.

Typische Anwendungen
BSP772TXUMA1 ist geeignet für 6 Anwendungs: Automotive Body Electronics - Lighting, Relay and Solenoid Replacement, Industrial 24V PLC Load Driver, HVAC and White Goods Motor Control, USB VBUS Power Switch in Automotive Head Units, Power Tool Battery Management.
Automotive Body Electronics - Lighting
The BSP772TXUMA1 drives interior and exterior automotive lamps directly from the 12 V battery bus with integrated protection that discrete solutions cannot match. At 2.6 A continuous current it can switch headlight bulbs, fog lamps, turn signals, and tail lights with margin for inrush. The 34 V over-voltage clamp absorbs 12 V jump-start transients; ESD protection to AEC-Q100-style requirements survives handling and field stress. Place the exposed pad on at least 1 square inch of 2 oz copper to handle 4 W peak dissipation during lamp cold-start inrush. STATUS pin reports open-load and short-circuit faults to the BCM microcontroller over a single wire, replacing the conventional fuse + relay + diode ladder with one IC.

Relay and Solenoid Replacement
The BSP772TXUMA1 directly replaces electromechanical relays in automotive and industrial systems, eliminating the click, the contact bounce, and the coil current draw. A typical 12 V relay coil draws 100-200 mA, well below the BSP772TXUMA1's 2.6 A envelope, leaving ample margin for solenoid inrush. The open-drain STATUS pin mirrors the relay contact state for diagnostic feedback, while over-current and over-temperature protection guard against welded contacts or stuck valves. PCB area drops by 80% versus a relay + socket + flyback diode. Lifecycle is also far higher since there are no moving parts to wear out, which is critical in industrial machinery with millions of switching cycles.
Empfohlen
Industrial 24V PLC Load Driver
In industrial 24 V PLC and process-control systems the BSP772TXUMA1 interfaces microcontroller I/O to high-current field loads such as valves, indicator lamps, and small heaters. Its wide 5 V to 34 V supply range covers both nominal 24 V rails and transient excursions during load dump on industrial DC buses. With 2.6 A continuous rating it can switch the majority of PLC output loads directly, while the STATUS pin feeds back into the PLC's diagnostic input for open-load detection - a requirement in functional-safety-relevant machinery. The exposed pad package mounts on standard SO-8 land pattern, easing retrofits into existing PLC output module designs.
Empfohlen
HVAC and White Goods Motor Control
The BSP772TXUMA1 controls small DC motors in HVAC dampers, refrigerator fans, and washing-machine pumps where its 2.6 A continuous rating covers most sub-30 W motor loads. Integrated reverse-battery protection allows direct connection to the appliance harness without external diodes; over-temperature shutdown protects the IC during motor stall conditions. The STATUS pin flags stall events to the appliance microcontroller, enabling controlled retry or service-code reporting - features that traditional thermal fuses cannot provide. The PG-DSO-8-6 package fits on compact PCB areas typical of white goods control boards.
Empfohlen
USB VBUS Power Switch in Automotive Head Units
Automotive head units and rear-seat entertainment systems use the BSP772TXUMA1 as a protected USB VBUS switch, sourcing 5 V to 2.6 A (after step-down) to portable devices while isolating faults from the head-unit supply rail. The integrated short-circuit protection limits fault current when a misbehaving device draws excessive load, preventing cable fires and PCB damage - critical safety requirements in vehicles. Over-voltage clamp protects against load-dump transients on the 12 V rail that feed the USB VBUS converter. STATUS pin notifies the head-unit MCU of over-current events so the system can disable USB and display a user-facing fault message.
Empfohlen
Power Tool Battery Management
Cordless power tools, garden equipment, and e-bike battery management systems use the BSP772TXUMA1 as a low-side or high-side protection switch between the Li-ion pack and the motor inverter. The 5 V to 34 V operating range covers 18 V and 36 V tool platforms. The 2.6 A rating is sufficient for auxiliary loads such as work-light LEDs, fan motors, and battery status indicators. Integrated over-current and over-temperature protection allow the BMS to disconnect the load safely during cell imbalance or short-circuit conditions, while the exposed-pad SO-8 package mounts easily on the tool's compact controller PCB.

Designhinweise
Estimated: at 2.6 A continuous load with typical RDS(on) of ~50 mOhm, power dissipation reaches approximately 0.34 W. In an enclosed automotive module at 85C ambient, the junction temperature rise with the exposed pad soldered to 1 square inch of 2 oz copper is roughly 30-50C - well within the 150C maximum. However, during a sustained short circuit the device enters over-current limiting and junction temperature may approach thermal shutdown at 150-170C. Always verify the PCB copper area is sufficient for your worst-case ambient. Without the exposed pad soldered, derate to 1.5 A maximum.
Place a 100 nF ceramic decoupling capacitor close to the VBB pins (5-8) to filter high-frequency noise from the load supply. Keep the STATUS pull-up resistor close to the IC pin (typical 10 kOhm to MCU VCC). The exposed pad must be soldered to a copper pour that extends to multiple inner layers via thermal vias (8-10 vias of 0.3 mm diameter) for heat spreading. Maintain at least 0.5 mm clearance between the high-voltage VBB copper and low-voltage logic traces to prevent arcing during load-dump events.
Do not operate the device without the exposed pad soldered - thermal resistance increases 5-10x and the device will overheat at currents above 1 A. Do not connect inductive loads without a flyback diode or transient voltage suppressor - while the BSP772TXUMA1 has a 34 V clamp, sustained inductive flyback can exceed this rating and damage the IC. The STATUS pin is open-drain and requires an external pull-up; do not leave it floating or the MCU will see random noise. Do not exceed 34 V on VBB; load-dump transients in 12 V automotive systems can reach 35-40 V without external TVS protection.
The IN pin is TTL/CMOS compatible and draws negligible current (< 1 uA). For noisy environments, add a small RC filter (10 kOhm + 1 nF) on the IN pin to debounce and reject sub-microsecond transients. The STATUS pin transitions during fault events; if your MCU input is not interrupt-capable, poll at least every 10 ms. The open-drain STATUS output allows wired-OR with other PROFET STATUS pins to a single MCU interrupt line, simplifying multi-channel fault monitoring in body control modules.
