Interpion I103H Voltage and current controller Datasheet

IP103H
Voltage and Current Controller
* The Main Differences of IP103 and IP103H are Vicm(Input Common Mode Voltage Range) and Vop(Operating Voltage)
DESCRIPTION
The IP103H is designed to be used in battery
chargers with a constant voltage and a constant current control.
This device is a monolithic IC that includes one independent op-amp and other op-amp for which the
non inverting input is wired to a 2.5V fixed Voltage
reference.
Integrating the reference and op-amps creates a solution for low cost charging applications.
