TPB4056A

1-A Single Cell Battery Linear Charger with High

Input Voltage

Features

Description

 Single-Chip Charger for 1-cell Li-ion or Polymer

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.

Battery

 Constant-Current/Constant-Voltage Battery

Charge

 Maximum 1000 mA Programmable Charge

Current

− Protection

− Wide Input From 4.55 V to 6.8 V or to 10.5 V,

The TPB4056A charge current is fully programmable

up to 1000 mA with an external resistor. The

TPB4056A automatically terminates the charge cycle

up to 26.5 V

 Charging Current Monitor and Thermal Foldback

 Power Presence Indication

when the charge current drops below

programmable minimal charging current of the set

charge current value after reaches float voltage.

 Soft start for Inrush Current Limitation

 Automatic Battery Recharge

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.

 No external MOSFET, Current Sensor or Diode

Required

 Operation Temperature: −40°C ~ +85°C

 Package options: ESOP-8, DFN2×2, DFN3×2,

DFN3×3

Applications

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.

 Portable Devices, GPS, ePOS, e-cigarette,

Walkie-talkie

 Wireless Devices, Bluetooth Headset

 Personal Electronics, Personal Healthcare

 Wearable Devices
