DC551 - LTC4002 Evaluation Kit

Features

• Evaluation Kit For LTC4002 - Standalone Li-Ion Switch Mode Battery Charger

Typical Application

Description

Demonstration circuit 551 is a complete constantcurrent/constant- voltage battery charger designed to charge one Lithium-Ion cell. Programmed for 3A charge current, this board features a 500kHz step down switching regulator controller driving a Pchannel MOSFET. A fixed 3 hour timer is included for charge termination in addition to a charge status LED to indicate a near-full-charge condition and a thermistor connection for battery temperature charge qualification. Because of the heat generated by the circuit, the thermistor must not be mounted on this board. A 10k resistor (R3) is used instead of a thermistor on this board.
