BTS723GW High-Side Smart Power Switch - Dual Channel 100mΩ Automotive Body Control IC
BTS723GW High-Side Power Switch for Automotive Applications
This dual-channel smart high-side power switch is specifically engineered to meet the rigorous demands of modern automotive electronics. Designed for 24V vehicle electrical systems, it provides a robust and efficient solution for driving resistive and inductive loads in body control modules.
Wide Operating Voltage Range
Supporting a broad supply voltage from 7.0V to 58.0V, this device ensures stable operation under severe voltage fluctuations commonly found in truck and agricultural vehicle environments. It offers a robust solution for 24V power distribution systems, featuring an overvoltage protection clamp up to 69V to safeguard against load dump events.
Enhanced Power Performance
With a typical ON-state resistance (RDS(ON)) of just 100mΩ per channel, the BTS723GW minimizes power dissipation and heat generation during operation. Each channel supports a nominal load current of 4.2A, with an internal current limitation set at 8.0A, providing a reliable interface for actuators, relays, and small motors.
Integrated Protection and Diagnostic Features
Reliability is paramount in automotive design. This switch integrates comprehensive protection mechanisms, including over-temperature shutdown, short-circuit protection, and overload current limiting. The built-in diagnostic feedback provides real-time status via open-drain outputs, allowing the microcontroller to detect open loads in OFF state and thermal shutdown events in ON state, significantly simplifying system-level error handling.
Optimized for Inductive Loads
When switching inductive loads, the integrated fast demagnetization of inductive loads ensures swift energy dissipation, protecting the switch and the load. Additionally, the logic ground is independent of the load ground, which optimizes signal integrity and improves Electromagnetic Compatibility (EMC) in dense PCB layouts.
Package and Quality
Housed in a PG-DSO-14 package, the BTS723GW is AEC-Q100 qualified, guaranteeing stable performance across the severe temperature range of -40°C to 150°C. Its green, RoHS-compliant design and low standby current make it an ideal choice for next-generation energy-efficient automotive and industrial power management systems.
