Voltage Detector IC Series Bipolar Voltage Detector ICs BD47xx series ●General 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-compact and have low current consumption, making them ideal for portable products. ●Features  High accuracy detection  Low current consumption  Very small package  Open collector “L” reset output  Package SSOP5 is similar to SOT-23-5 (JEDEC) ●Typical Application Circuit Datasheet ●Key Specifications  Detection voltage range: 1.9V to 4.6V (Typ.) 0.1V steps  High accuracy detection voltage: ±1%  Low current consumption: 1.6µA (Typ.)  Operating temperature range: -40°C to +75°C ●Package SSOP5 2.90mm x 2.80mm x 1.25mm ●Applications Circuits using microcontrollers or logic circuits that require a reset.
