DATASHEET
1A Standalone Linear Li-lon Battery Charger with Thermal Regulation TD9056
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.
Programmable Charge Current Up to 1000mA
No MOSFET, Sense Resistor or Blocking Diode
