Power management IC for cellular phones
BH6039KN
Description
BH6039KN is a compound power management IC
incorporating regulator, detector, charge control circuit
for charging lithium battery, and each driver for vibrator,
LED, back light. The lithium battery charging circuit
incorporates each monitor circuit such as the micro-
controller charging current circuit.
Features
1) Built-in 5-channel CMOS type regulator
2) Built-in 4-channel detector circuit can vary delay time
by external capacitor.
3) Built-in each driver for vibrator, LED, back light
4) Built-in charge control circuit for charging lithium battery
in the set.
5) Small QFN48U package
