BL8595 is designed for battery charging controller with patent BICMOS process, which
Overview
BL8595 18V/1A PNP with N-MOSFET CHARGE IC.
Key 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.
