G5805 Datasheet | Global Mixed-mode Technology

Global Mixed-mode Technology Single Cell Li-Ion Battery Linear Charger Features - No External Power MOSFET, Sense Resistor or Blocking Diode Required - 1% Regulation Voltage Accuracy - Programmable Constant Charge Current Limit up to 800m A - Automatic Recharge - plete Pre-Charge, Constant Current, Constant Voltage and Charge Termination Charge Procedure - Support for 5V Power Supply Voltage - Internal Thermal Protection Circuit - TSOT-23-5 Package Applications - MP3 Players - Cellular Phones - PDAs - Hand-Held Devices General Description The G5805 is a standalone linear Li-Ion battery charger with a plete pre-charge, constant-current and constant-voltage charge loop. No external power MOSFET, sense resistor and blocking diode is required due to internal power MOSFET architecture. The charge voltage is regulated at 4.2V, and the charge current is programmable by an external resistor. After the final regulation voltage is reached and the charge current drops to 1/10th the programmed charge current, the open drain NMOS CHRG pin would be turn off automatically without terminating the charge loop. Other Features include under voltage lockout, automatic recharge, over temperature protection and a charge status indication pin.
