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)
