High-accuracy
Low current consumption
General-purpose
RESET IC
BD47XXG series
Description
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.
