S-191L/N Series Automotive, 36 V, Supply Voltage Divided Output Window Voltage Detector

ABLIC's window voltage detector features three monitoring functions in a single chip

Image of ABLIC's S-191L/N Series Window Voltage DetectorABLIC's S-191L/N series has supply voltage divided output to help the microcontrollers monitor voltage. No external parts are required to convert the high voltage supplied by a battery or other source to the voltage that can be input to microcontrollers. This contributes to fewer parts and a lower standby current.

The S-191L/N series comes in an ultra-small automotive HSNT-8(2030) package and has an ultra-low current consumption of 0.9 μA. A detection voltage monitoring accuracy of ±1.5% (over the entire temperature range) helps improve voltage monitoring accuracy.
