Datasheet Voltage Detector IC Series Bipolar Voltage Detector ICs BD47xx series General Description Key Specifications The BD47xx series is a Voltage Detector IC, Detection voltage range: 1.9V to 4.6V (Typ.) developed to prevent system errors at transient state, 0.1V steps when the power of CPU or logic circuit switches High accuracy detection voltage: 1% ON/OFF or in cases of momentary shut down. These Low current consumption: 1.6A (Typ.) ICs consist of three terminals (power supply, GND and Operating temperature range: -40C to +75C reset output) to detect power supply voltages and outputs reset signals of various systems. These ICs are ultra-compact and have low current consumption, Package making them ideal for portable products. SSOP5 2.90mm x 2.80mm x 1.25mm Applications Features Circuits using microcontrollers or logic circuits that require High accuracy detection a reset.
