Overview
The TPB4056B is a cost-effective, high-integration linear charger for single cell Li-ion or Li-ion polymer batteries. The device supports CC/CV charge from either a USB port or an AC adapter. Low BOM component requirement makes the size of the whole system small. High input voltage range with over-voltage protection supports lowcost unregulated adapters.
The TPB4056B charge current is fully programmable up to 1000 mA with an external resistor. The TPB4056B automatically terminates the charge cycle when the charge current drops below 10% of the set charge current value after the battery voltage reaches the float voltage.
The TPB4056B implements two indication pins: CHRG and STDBY, allowing connection to microcontroller or LED to show device status. With open-drain structure, CHRG stays low during charging, and STDBY stays low after charging complete. Other pins are in the high-impedance state.
The TPB4056B features thermal foldback function to limit the charge current and protect the device from over junction temperature fault. The TPB4056B also integrates current monitor, UVLO, and OVP functions to prevent the device from damage.
