LP4076B 1A Standalone Single-Cell Linear Charger
■The LP4076B is a highly advanced linear charger for single-cell Li-Ion and Li-Polymer batteries. The device is ideally suited for portable applications due to low number of external components required.
■The device employs a full charge algorithm with trickle current, constant current (CC), constant voltage (CV) modes, charge termination and automatic recharge. The device supports charge current up to 1A, programmed by an external resistor. The device can withstand an input voltage up to 28V, which can protect the charger from any accidental insertion of a high-voltage supply or a hot insertion. The device can withstand a BAT voltage up to 14V, which is suited for power battery applications. Without an input supply, the battery leakage current is only 30nA typical.
■The device provides various safety features for battery charging, including input under voltage lockout (UVLO), input over-voltage protection (OVP), battery reverse connection protection, cold/hoot battery temperature protection, and thermal regulation protection that is implemented by reducing the charge current when the junction temperature reaches 140℃.
■The LP4076B is available in an ESOP-8 package.
