Operation temperature : 150°C max. (S-191L/191NxxxxS) ｜ 125°C max. (S-191L/191NxxxxA) ｜ 105°C max. (S-191L/191NxxxxH)

This IC, developed using CMOS technology, is a high-accuracy window voltage detector with the supply voltage divided output that detects undervoltage and overvoltage. 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 (V_SENSE) 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% (C_D = 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 V_SENSE into V_SENSE/6, V_SENSE/8, V_SENSE/12 or V_SENSE/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.
