Application Note : Reset ICs (Voltage Detectors)
R3119 and R3150 can detect 36V input voltage directly. Conventionally, monitoring the voltage of 6V or higher was required to use resistance dividers.
But, R3119 and R3150 can achieve the detector threshold accuracy of ±1.5% without external resistors.
Ricoh Reset IC can implement a supervisor with a low-voltage node by lower voltages of 0.5V operating voltage and 0.7V low-detector threshold, and achieves the detector threshold with ±0.8% high accuracy.
Lower voltage and higher accuracy of the detector threshold can make effective use of battery and contribute to energy-conservation.
