Dec. 2002 - 1 - WWW.INTERPIONSEMI.COM Voltage and Current Controller The IP103H is designed to be used in battery chargers with a constant voltage and a constant cur- rent control. This device is a monolithic IC that includes one in- dependent 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 so- lution for low cost charging applications. Operational Amplifiers - Low Supply Current : 200uA/amp - Medium Speed : 1.5MHz - Low Level Output Voltage Close to VEE : 0.1V Typ. -Wide Power Supply Range; 3.6~28V Adjustable Shunt Regulator - Fixed Output Voltage Reference 2.5V - Sink Current Capability : 0.5 to 150mA - 1% Voltage Precision - Latch-up Immunity
