A4052 BATTERY MANAGEMENT 1A IS COMPATIBLE WITH THE USB INTERFACE, LINEAR BATTERY MANAGEMENT CHIP
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.
