Automotive, 125°C Operation, 36 V, Supply Voltage Divided Output, Voltage Detector with SENSE Pin Reverse Connection Protection S-19117/19119xxxA Series

This IC, developed using CMOS technology, is a high-accuracy voltage detector with the supply voltage divided output. The detection voltage and release voltage are fixed internally with an accuracy of ±1.5%.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even if the SENSE pin voltage (VSENSE) falls to 0 V. The SENSE pin also has a built-in reverse connection protection circuit that reduces current in the SENSE pin during a reverse connection.
The release signal can be delayed by setting a capacitor externally, and the release delay time accuracy is ±15% (CD = 3.3 nF). The output form is Nch open-drain output.
The supply voltage divided output is prepared in this IC. The supply voltage divided output is a function that divides the VSENSE into VSENSE/6, VSENSE/8, VSENSE/12 or VSENSE/14 and outputs the voltage. For example, this function makes it possible that the IC connects to a low voltage microcontroller A/D converter directly and the microcontroller monitors a battery voltage.
