BTS723GWXUMA1 개요
A high-side power switch is a type of power distribution switch that connects a load (such as a lamp, solenoid, or motor) to the positive supply rail while the low-side of the load remains at chassis ground. It belongs to the broader category of power management ICs (PMICs), specifically the load driver / smart switch sub-category. Compared to a discrete MOSFET plus fuse arrangement, a smart high-side switch integrates protection, diagnosis, and PWM capability into one IC, simplifying the ECU design and reducing PCB area.
Key features include very low standby current (a few µA typical), CMOS-compatible input thresholds, fast demagnetization of inductive loads via integrated active Zener clamps, stable behavior at undervoltage, and a defined restart behavior after over-current or thermal shutdown. Each channel provides its own status feedback and fault flag through a shared diagnostic output, allowing the microcontroller to distinguish between normal operation, short circuit to ground, short circuit to battery, and open load conditions.
The BTS723GWXUMA1 is fabricated using Infineon's proprietary SMART7 vertical power technology, which delivers very low R_DS(on) per channel, strong avalanche ruggedness, and tight thermal coupling between the two output FETs on a single die. The PG-DSO-14-37 package exposes a thermal pad on the underside for PCB copper cooling, enabling sustained 2× 2.5 A operation without external heatsinks in typical 12 V automotive body-control modules.
Typical applications include automotive body electronics (door modules, seat controllers, mirror fold), dual-rail lamp drivers (interior lighting, turn indicators), HVAC blower and resistor switching, and any 12 V/24 V load where two independent high-side channels are needed with full protection and ISO 7637-2 transient immunity. The wide operating voltage range (6 V to 24 V nominal, with load-dump survival to 40 V per the Classic PROFET specification) makes the part equally suitable for trucks and 24 V commercial-vehicle platforms.
When designing with this part, place the input pin capacitor (typically 100 nF) as close as possible to the Vbb pin and route the two output channels with wide copper pours to keep the on-state resistance low and share heat between channels. Always respect the maximum energy rating during demagnetization (E_AS) when switching inductive loads, otherwise the active clamp Zener can be permanently damaged.

일반적인 애플리케이션
BTS723GWXUMA1 적합 용도: 6 애플리케이션s: Automotive Body Control Module (BCM), Dual Automotive Lamp Driver, HVAC Blower and Resistor Switching, Industrial 24 V Load Switching, Power Distribution / Load Multiplexer, 24 V Truck / Commercial-Vehicle Body Electronics.
Automotive Body Control Module (BCM)
The BTS723GWXUMA1 fits the BCM because each channel delivers 2.5 A continuous at 24 V nominal, AEC-Q100 qualification is required, and the PG-DSO-14-37 dual-channel package halves the PCB area vs two single-channel switches. Used to drive interior lamps, mirror heaters, and door-lock solenoids with integrated short-circuit and over-temperature protection, the part withstands ISO 7637-2 transient pulses and 24 V truck battery systems. Its very low µA-level standby current prevents quiescent-drain complaints during long vehicle parking, a critical BCM requirement. Typical wiring places the BTS723GWXUMA1 between the 12 V/24 V Vbb rail and the load, with each output pin direct to a bulb or solenoid return-to-ground.

Dual Automotive Lamp Driver
For dual incandescent or LED lamp channels up to 2.5 A each, the BTS723GWXUMA1 provides the high-side switching plus inrush-current protection needed for cold-filament lamps. Its fast demagnetization active clamp handles the inductive kick from relay-driven circuits and turn-indicator loads. Compared with discrete MOSFET plus fuse solutions, the part's diagnostic output reports open-load and short-circuit faults back to the BCM microcontroller, enabling OBD-II compliant bulb-out detection. Per the Classic PROFET datasheet, designers can PWM the input up to several hundred Hz for dimming, though thermal derating applies at high duty cycles.
추천
HVAC Blower and Resistor Switching
The BTS723GWXUMA1's 2.5 A continuous rating and 24 V operating window suit HVAC blower-resistor switching and seat-heater control in 12 V and 24 V vehicles. The active Zener clamp absorbs the back-EMF when a DC motor is switched off, protecting the FET from avalanche damage and allowing direct connection to inductive loads without external flyback diodes. With two channels in one package, designers can drive a blower + heater combination from a single IC. The exposed thermal pad of the PG-DSO-14-37 spreads heat between the two output FETs during simultaneous motor-start inrush events.
추천
Industrial 24 V Load Switching
Beyond automotive, the BTS723GWXUMA1 is widely used in industrial 24 V PLC and factory-automation I/O modules where two channels of protected high-side switching are required. The CMOS-compatible inputs interface directly with 3.3 V or 5 V microcontrollers, eliminating level-shifters and reducing BOM cost. The AEC-Q100 qualification gives designers extra margin in harsh-environment industrial applications subject to temperature cycling and electrical noise. The PG-DSO-14-37 package plus exposed pad allows direct soldering to standard FR4 boards without heatsinks.
추천
Power Distribution / Load Multiplexer
In power-distribution modules the BTS723GWXUMA1 acts as a load multiplexer, switching between two subsystems (e.g., auxiliary lighting and trailer socket) under microcontroller command. Each channel's diagnostic pin reports the actual load state back to the ECU, enabling smart fault recovery without external current-sense amplifiers. The very low standby current prevents battery drain when the vehicle is parked for months. With 2.5 A per channel the part can also drive smaller DC pumps or valve solenoids used in commercial vehicle body electronics.
추천
24 V Truck / Commercial-Vehicle Body Electronics
The BTS723GWXUMA1 is rated for 24 V nominal battery systems (trucks, buses, construction equipment) with load-dump survivability to 40 V, making it a direct fit for commercial-vehicle body controllers that must operate from a 24 V battery bus. Two channels per package reduce part count on dense PCBs, while AEC-Q100 qualification and -40 C to +150 C junction range handle under-hood thermal stress. Designers commonly use this part for tail-lamp, marker-lamp, and mirror-fold loads where 24 V supply is mandatory.

설계 노트
Estimated: at Vbb = 14 V, I_OUT = 2.5 A per channel, and R_DS(on) ≈ 50 mΩ (typical for Classic PROFET at 25 °C junction), each channel dissipates approximately 0.31 W and both channels together about 0.62 W. With the PG-DSO-14-37 thermal pad soldered to at least 1 cm² of 1 oz copper on FR4, theta_JA stays below 50 K/W and junction rise stays under 31 °C above ambient - well within the 150 °C maximum. Use larger copper pours or thermal vias if both channels continuously carry the full 2.5 A.
Place a 100 nF ceramic decoupling capacitor as close as possible to the Vbb pins (1 and 14, which are internally bonded). This suppresses voltage transients during fast switching edges of inductive loads and helps the part pass ISO 7637-2 pulse 1 and 2a tests. Keep the Vbb copper pour wide (≥2 mm) to carry 2.5 A continuous current without significant trace resistance, and route both OUT pins of each channel together to balance current sharing.
Do not exceed the maximum energy rating E_AS during demagnetization of inductive loads. The active Zener clamp typically handles single-pulse avalanche of a few hundred mJ, but continuous PWM switching of large inductors (e.g., relay coils or solenoids) can exceed this. Either add an external free-wheeling diode across the load or limit PWM frequency to keep total E_AS within the datasheet limit. Also respect the -40 °C minimum operating temperature; below this, R_DS(on) increases and current capability decreases.
