Overview

The TPB4056A is a cost-effective, high-integration linear charger for single cell Li-ion or Li-ion polymer batteries. The device support CC/CV charge from either USB port or AC adapter. Low BOM component requirement makes the whole system small in size.

High input voltage range with over-voltage protection supports low-cost unregulated adapters.

The TPB4056A charge current is fully programmable up to 1000 mA with an external resistor. The TPB4056A automatically terminates the charge cycle when the charge current drops below a programmable minimal charging current of the set charge current value after reaches float voltage.

The TPB4056A implements two indication pins, PPR and CHG, allowing connection to microcontroller or LED to show device status. With open-drain structure, PPR pin stays low while input voltage is within operation range, and CHG stays low during charging state, else pins are in the high impedance state.

The TPB4056A features thermal foldback function to limit the charge current and protect the device from over junction temperature fault. The TPB4056A also integrates current monitor, UVLO, OVP function to prevent device from damage.
