DESCRIPTION
The A4052 is a constant- current / constant- voltage charger circuit for single cell lithium-ion batteries. The device includes an internal power transistor, does not need external current sense resistor and blocking diode in applications. A4052 requires minimal external components, and meet the USB bus specification, is very suitable for portable applications in the field.
Thermal modulation circuit can control the internal chip temperature in a safe range when the device power dissipation be relatively large or the ambient temperature be higher. Within a fixed constant charge voltage 4.2V, can also be adjusted by an external resistor.
When the input voltage (AC adapter or USB power supply) power is lost, A4052 automatically enters a low power sleep mode, then the battery current consumption is less than 0.1μA. Built-in protection circuits against irrigation, when the battery voltage is higher than the input voltage, automatically turn off built-in power MOSFET. Other features include low input voltage latch, automatic recharge, the battery temperature monitoring, Built - in OVP protection and charge status / charge status indication functions.
The A4052 is available in PSOP8 package.
