DATASHEET
1A Standalone Linear Li-lon Battery Charger with Thermal Regulation TD9056A/B
General Description
Features
The TD9056 is a complete
constant-current/constant-voltage linear charger for
single cell lithium-ion batteries. Its SOP package and low
external component count make the TD9056 ideally
suited for portable applications. Furthermore, the
TD9056 can work within USB and wall adapter.
No blocking diode is required due to the internal
PMOSFET architecture and have prevent to negative
Charge Current Circuit. Thermal feedback regulates the
charge current to limit the die temperature during high
power operation or high ambient temperature. The
charge voltage is fixed at 4.2V, and the charge current
can be programmed externally with a single resistor. The
TD9056 automatically terminates the charge cycle when
the charge current drops to 1/10th the programmed value
after the final float voltage is reached.
TD9056 Other features include current monitor, under
voltage lockout, automatic recharge and two status pin to
indicate charge termination and the presence of an input
voltage.
