VN7140ASTR Automotive Single-Channel Smart High-Side Driver
The VN7140ASTR is an automotive-grade, single-channel smart high-side driver from STMicroelectronics. It is designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, delivering a maximum output current of 8 A across a 4 V to 28 V load voltage range. The device features a typical on-state resistance of 140 mΩ per channel, a typical current limitation of 12 A, and an extremely low standby current of 0.5 µA at 13 V, operating across a junction temperature range of -40°C to +150°C. Its integrated MultiSense analog feedback, comprehensive protection suite, and configurable fault management make it a robust, space-saving solution for automotive body electronics and advanced driver-assistance system (ADAS) power distribution.
The VN7140ASTR is engineered for all types of automotive resistive, inductive, and capacitive grounded loads, with particular optimization for automotive signal lamps up to R10W or LED rear combination configurations. It serves as a protected power supply for ADAS systems, specifically radar modules and sensor clusters that demand clean, supervised 12 V distribution. Beyond automotive, the device's 4 V to 28 V operating range, 8 A capability, and industrial-grade robustness make it suitable for general-purpose power distribution in factory automation, programmable logic controllers, and smart sensor nodes. Its 0.5 µA standby current and configurable low-power diagnostics are especially valuable in always-connected vehicle platforms where battery drain must be minimized during park mode.
Alternative high-side driver
● VN7040AJTR: Fully pin-to-pin compatible single-channel high-side driver from ST's VIPower portfolio, providing a direct drop-in alternative for VN7140ASTR-based designs with verified 8-SOIC footprint compatibility.
● VN7020AJTR: Pin-compatible VIPower high-side driver featuring a lower nominal RDS(on) class for higher-current automotive actuator and lamp-driving requirements within the same SO-8 package.
● BTS5008: Infineon PROFET smart high-side power switch delivering comparable voltage and current ratings with integrated diagnosis and protection, suitable for cross-supplier automotive power distribution designs.
