Overview
This IC is a linear lithium battery charger with a 33V maximum input voltage rating and 1.2A maximum charge current, employing trickle/constant-current/constant-voltage charging. The charge voltage is set to 4.2V or 4.35V, and the charge current is programmable via an external resistor. When the battery voltage reaches 4.2V or 4.35V and the charge current drops to C/5 or C/10 of the programmed value, the IC terminates charging and enters standby mode. When the power supply is removed, the IC automatically enters a low-power standby state. This IC is suitable for USB power and adapter power operation. Thanks to the internal PMOSFET architecture and reverse-charge protection circuitry, no external sense resistors or isolation diodes are required.
