BD4721
BD4721 is Bipolar Voltage Detector manufactured by ROHM.
Description
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 ultra-pact and have low current consumption, making them ideal for portable products.
