BD4721 - Rohm

BD4721 Bipolar Voltage Detector

The BD47xx series is a Voltage Detector IC, developed to prevent system errors at transient state, when the power of CPU or logic circuit switches ON/OFF or in cases of momentary shut down. These ICs consist of three terminals (power supply, GND and reset output) to detect power supply voltages and outputs reset signals of various systems. These ICs are ultr.
