Chip S矽ou源rc特e T科ek技 CST4056 1A Li-ion Battery Linear Charger CST4056 Description The CST4056 is a standalone linear Li-ion battery charger with ESOP8/DFN2X2-8L package. With few external ponents, CST4056 is well suited for a wide range of portable applications. Charging current can be programmed by an external resistor. In standby mode, supply current will be reduced to around 35u A. When the input voltage is disconnected, CST4056 enters the sleep state, and the battery leakage current will drop below 1u A. Other Features include UVLO, automatic recharge, charge status indicators and thermal regulation. CST4056 Feature - Up to 1000m A Programmable Charge Current - No External MOSFET, Sense Resistor, or Blocking Diode Required - Standalone Linear Charger for Single Cell Li-ion Batteries - Preset Charge Voltage with：4.2V-1% ~ 4.2V＋2% - Automatic Recharge - Charge Status Indicators for No Battery and Charge Failure Display - C/10 Charge Termination - 35u A Standby Supply Current - 2.9V Trickle Charge Voltage - Thermal Protection - Soft-Start to Limit Inrush Current - reverse protection CST4056 Appilication - Mobile Phone、PDA - MP3、MP4 - Charger - DSC - Palmtop - Bluetooth , GPS - Portable Device Package Type : ESOP8 / DFN2- 2-8L CST4056 Pin...
