Overview
The 4056 is a single-cell lithium-ion battery constant-current/constant-voltage linear charger. Its simple external application circuit makes it ideal for portable device applications, suitable for operation with USB power supplies and adapter power supplies. An internal reverse-charge protection circuit eliminates the need for an external isolation diode. Thermal feedback automatically adjusts the charge current to limit the die temperature during high-power operation or elevated ambient temperature conditions. The 4056 has a charge termination voltage of 4.2V, and the charge current can be set via an external resistor. When the charge current drops to 1/10 of the programmed value, the 4056 automatically terminates the charging process.
Applications
- Charging dock
- Bluetooth headsets, GPS
- Mobile phones, PDA, MP3/MP4
- Digital cameras, mini speakers, and other portable devices
Key features
- Pre-charge voltage: 4.2V
- Reverse battery protection
- Maximum charge current: 1000mA
- Ultra-low quiescent current of 1μA in battery-only mode
- No external MOSFET, sense resistor, or blocking diode required
- Thermal regulation maximizes charge rate
- Automatic recharge
- C/10 charge termination
- Trickle charge threshold: 2.94V
- Package: ESOP8
- When input voltage is removed, the 4056 automatically enters low-current standby mode with standby current reduced to 1μA
