Chipown AP5054H Standalone Linear Li-Ion Battery Charger with Thermal Regulation in SOT General Description Features The AP5054H is a complete constant current & constant voltage linear charger for single cell lithium-ion batteries. Its SOT package and low external component count make the AP5054H ideally suited for portable applications. Furthermore, the AP5054H is specifically designed to work within USB power specifications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The AP5054H automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. When the input supply (wall adapter or USB supply) is removed, the AP5054H automatically enters a low current state, dropping the battery drain current to less than 0.5μA. The AP5054H can be put into shutdown mode, reducing the supply current to 180μA. Other features include charge current monitor, undervoltage lockout, automatic recharge and status indication.                Input Voltage up to 20V Input Over Voltage Protection：6.1V Programmable Charge Current Up to 750mA No MOSFET, Sense Resistor or Blocking Diode Required Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating Charges Single Cell Li-Ion Batteries Directly from USB Port Preset 4.2V Charge Voltage Charge Current Monitor Output for Gas Gauging Automatic Recharge Charge state pairs of output, no battery and fault status display C/10 Charge Termination 180μA Supply Current in Shutdown 2.9V Trickle Charge Threshold Soft-Start Limits Inrush Current Available in SOT23 Package Package SOT-23-5L Applications      CHRG 1 GND 2 BAT 3 Cellular Telephones, PDAs, MP3 /MP4 Players Charger Digital Camera Electronic Dictionary Bluetooth ,GPS Applications SOT-23-6L 5 4 PROG CHRG 1 6 PROG GND 2 5 STDBY BAT 3 4 VCC VCC Typical Application Circuit Vin 1uF LED Red V in BAT VCC AP5054HTBER BAT VCC 4.2V Li - lon Battery 1uF LED Green LED Red AP5054HTCER 4.2V Li - lon Battery CHRG STDBY PROG CHRG GND 2K 24/F, Building E, Wangzhuang Technology Innovation Center, Longshan Road,New District, Wuxi PROG GND Tel: +86(510)85217718 http://www.chipown.com.cn 2K V1.1 1/9 PDF
