Product Lineup View All Products/Datasheets

An automotive voltage detector (battery monitoring & reset IC) is a power supply IC that is mainly used for monitoring the power supply voltage of automotive electronic devices. It monitors and detects whether the voltage drops below a threshold or exceeds a certain level.
ABLIC's automotive voltage detectors (battery monitoring & reset ICs) feature a wide range of options, including 36V operation/45V rating battery direct connection, VDD/SENSE detection, high-temperature operation up to 150°C, low current consumption of 270nA typ., and fast detection response that enhances safety. 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.
