BD47XXG series

High-accuracy

Low current consumption

BD47XXG is a series of RESET 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.

SMP5
