描述 Description

The BD47□□G Series is a reset IC that was developed to prevent system errors at transient state when the power of CPU or logic circuit switches ON/OFF or 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 are realized low current consumption, making them ideal for portable products.

特性 Features

1) Detection voltage range: 0.1-volt step line-up 1.9~4.6V (Typ.)

2) High accuracy voltage detection: ±1

3) Low current consumption

4) Open collector “L” reset output

5) Compact SSOP5 package

Applications

All electronic devices that use microcontrollers and logic circuits
