1A Li-ion Battery Charger Integrated with Protective PMOSFET

AW3210A is a highly integrated Li-Ion battery charger. AW3210A continuously detects the input voltage, if V IN exceeds the threshold voltage and lasts longer than 100ns, the internal power P-MOSFET turned off, CHRIN pulled down. AW3210A Built-in current limiting protection circuit, the charging current is limited to a safe range. AW3210A possesses the specific K-Charge TMtechnology, the output current can be adjusted smartly according to the chip temperature to ensure safety during the entire charging process. AW3210A integrates the charging P-MOSFET, eliminating  the  need  for  external  charging P-MOSFET and Schottky Diode among a phone charging system. And the reverse current blocking function has been designed in AW3210A, when the CHRIN voltage drops below the OUT, charging P-MOSFET turned off, preventing current draining from the lithium-ion battery into AW3210A. AW3210A is available in DFN 3×3-10L package.
