BD4201FV Regulators 1/8 Battery Backup IC BD4201FV

BD4201FV is a battery backup IC. Switch that detect battery voltage and switch into back up power supply and 3-channel regulator are incorporated into a single chip. Current consumption is 15μA (Max.). This IC is perfect for portable appliances.

zApplications Portable video, Digital camera

zFeatures 1) Low quiescent current Normal operation < 15.0μA Max. Backup mode < 2.1μA Max. 2) 3 high accurate voltage regulators 3) Low dropout voltage, and high accurate voltage detectors (CS, RESET) 4) Control circuit; Backup 5) Special sequence; For shifting to the backup mode. It need to make main battery over +Vdet1 once.
