LPSemi Microsource LP28019B 1A single-chip lithium-ion and lithium-polymer charger is a complete single-cell lithium-ion battery constant current/constant voltage linear charger. It adopts ESOP8 package and has built-in MOSFET structure. It does not require external sensing resistors or blocking diodes, making it very suitable for portable device applications.

The LP28019B regulates charge current with thermal feedback to limit die temperature during high-power operation or high ambient temperatures. The charging voltage is fixed at 4 2V and the charging current is externally programmable through a single resistor.
