Voltage detectors
Bipolar Voltage detector IC
BD47××G series
BD47××G is a series of Voltage detector ICs developed to prevent system error at transient state when the power of CPU
and logic circuit switches ON/OFF or shutdown. These ICs consist of Power, GND, and reset output to detect power
supply voltage of various systems and to output reset signal. These ICs are more practical for portable products because
of their ultra-small package and low current consumption.
Portable products, Equipments with CPU and logic circuit
1) Detection voltage : 0.1V step line up 1.9∼4.6V(Typ.)
2) High-accuracy voltage detection ±2% guaranteed
3) Low current consumption
4) “L” reset output of open collector
5) Small SSOP5 package
