Typical Applications
BTS724GXUMA1 is suitable for 6 applications: Automotive Body Control Module, Industrial 24V PLC Output Module, LED Lighting Driver Cluster, Relay and Solenoid Replacement, Power Distribution Network, Heating Element Driver.
Automotive Body Control Module
The BTS724GXUMA1 is ideal for automotive body control modules driving interior lighting, seat heating, and mirror adjustment. Each of the 4 channels handles 3 A continuous load current, enabling direct connection to 12 V bulbs, PTC heaters, and small DC motors. The embedded protection (overload, short-circuit, over-temperature) is essential for the harsh automotive environment where wiring faults are common. Per-channel diagnostic feedback lets the MCU report fault codes via CAN/LIN, supporting OBD-II compliance. With a 5.5 V to 38 V supply range, the device survives cold-crank and load-dump transients without external protection.
Recommended
Industrial 24V PLC Output Module
The BTS724GXUMA1 suits industrial 24 V PLC discrete output modules where 4 isolated or grouped loads must be driven from a logic-level MCU. With 5.5 V to 38 V supply, the device interfaces directly to 24 V factory supply rails. CMOS-compatible ground-referenced inputs simplify the interface to 3.3 V or 5 V microcontrollers, eliminating the need for optocouplers in some architectures. The fast demagnetization of inductive loads allows safe switching of 24 V solenoids, relays, and small contactors. Over-temperature shutdown protects against wiring shorts common in factory environments.
Recommended
LED Lighting Driver Cluster
For multi-string LED lighting applications, the BTS724GXUMA1 provides 4 independent constant-current channels capable of driving automotive tail-light, signal-light, or interior ambient LED strings. The 3 A per-channel rating covers most 12 V LED strings up to approximately 30 W. The diagnostic feedback can detect open-string or short-string faults for safety-critical exterior lighting. Compared to discrete MOSFETs, the integrated over-temperature protection prevents thermal runaway if a string fails short. Wide supply range tolerates 12 V cranking dips and 24 V truck systems.
Recommended
Relay and Solenoid Replacement
The BTS724GXUMA1 can replace electromechanical relays and solenoids in automotive and industrial systems where high reliability, silent operation, and diagnostic feedback are required. Each channel handles the inrush current of solenoids while fast demagnetization handles back-EMF from inductive kick. Solid-state switching eliminates contact bounce and mechanical wear, extending service life beyond electromechanical alternatives. Per-channel diagnostics enable predictive maintenance in industrial systems.
Recommended
Power Distribution Network
As a power distribution node in distributed 12 V or 24 V architectures, the BTS724GXUMA1 provides 4 fused and protected rails from a single supply input. Each channel's overload protection acts as a per-channel electronic fuse, eliminating the need for replaceable blade fuses in accessible locations. The status output enables central fault monitoring, reducing wiring complexity and improving serviceability in body control and chassis modules.
Recommended
Heating Element Driver
The BTS724GXUMA1 drives resistive heating loads such as seat heaters, mirror heaters, and steering wheel heaters in 12 V automotive body electronics. Each channel handles up to 3 A continuous, covering single-zone heaters. PWM control via the CMOS-compatible input enables duty-cycle-based temperature regulation. The over-temperature protection prevents thermal runaway if the heater element shorts to chassis, an essential safety feature for in-cabin heaters.

Key Differentiators
- 4 independent channels in a single PG-DSO-20 package (vs BTS721L1T)
- Lower RDS(on) optimized for moderate-current applications (vs BTS726L1)
- Per-channel diagnostic feedback (vs Single-channel PROFET family)
Design Notes
Estimated: at 3 A per channel across all 4 channels from a 12 V supply with 1 V drop, total package dissipation is approximately 12 W. The PG-DSO-20 requires substantial copper pour on the Vbb and GND pins to stay within the thermal derating curve. Mount on a multi-layer PCB with at least 2 oz copper on outer layers and thermal vias connecting to inner ground planes. Derate per-channel current to 1.5-2 A if all channels run continuously at 25 C ambient.
Place Vbb decoupling capacitors (100 nF ceramic plus 10 uF electrolytic) as close as possible to the Vbb pins. Wide Vbb traces reduce parasitic inductance, which can cause overvoltage transients during fast demagnetization of inductive loads. Ground-referenced CMOS inputs allow direct connection to 3.3 V or 5 V MCUs without level shifters, simplifying PCB layout. Keep the diagnostic status trace away from switching output traces to avoid noise coupling.
Do not connect supply voltages higher than Vbb(AZ) without external current limit on GND and status pins (a 150 ohm resistor for the GND connection is recommended per the datasheet). Inductive loads must include flyback protection; the BTS724GXUMA1 has internal fast demagnetization but external TVS diodes may be required for very high energy inductors. Reverse-battery protection (series diode or P-MOSFET) is mandatory for automotive 12 V systems to survive negative transients.
