Automotive Supervisory Circuits

Nisshinbo Automotive Supervisory Circuits are a broad portfolio of watchdog timers and voltage detectors. The devices have various electrical characteristics like highly accurate voltage detection, low supply currents from 290nA, and a wide variety of operating input voltages from 0.5V to 60V. Most of the ICs have additional features like a manual reset pin, SENSE pin, power-on reset, output voltage inversion, and over-/undervoltage detection suitable for functional safety.
