Automotive Voltage Detectors (Battery Monitoring & Reset ICs)

Product Lineup View All Products

ABLIC's automotive voltage detectors (battery monitoring & reset ICs) offer a wide range of products, including 36V operation/45V rating battery direct connection, VDD detection/SENSE detection, high-temperature operation of 150°C max., and low-current consumption of 270nA typ. In addition, with a variety of functions, such as window type, manual reset, SENSE pin reverse connection protection, and supply voltage divided output, they are ideal for monitoring the voltage of automotive power supplies.
Moreover, our automotive voltage detectors are AEC-Q100 qualified and PPAP (Production Part Approval Process) capable. This ensures high quality and reliability, making them suitable for safety-critical components such as BMS and EPS motors. We also support customers' automotive application designs by providing FIT rates.
