BELLING BL8595 18v-1a pnp with n-mosfet charge ic Datasheet

BL8595
18V/1A PNP with N-MOSFET CHARGE IC
DESCRIPTION
FEATURES
BL8595 is designed for battery charging controller
with patent BICMOS process, which features PNP
characteristics and a NMOS for base current
blocking. Such base current blocking feature cut off
the base current of PNP transistor when source
current of NMOS is removed, or the gate voltage
indicating the NMOS off.



BL8595 is also suitable for high side switch in a
system with multi power supplies, when isolating
different power supplies becomes essential.
APPLICATIONS

Range of operation input voltage: Max 18V
Charging current up to 1A
Operation dropout voltage:0.3V@500mA
High isolating N-MOSFET
Package type:SOT23-6
Environment Temperature: -20C~85C
Cell phone and other portable device
BL8595 can block reverse voltage as high as 10V. So
it is safe enough for mobile phone system or other
portable device powered by 1 cell Li-ion battery.
BL8595 is available in SOT23-6L.
