描述:产品详情:
The TD9054 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. Its SOT23-5 package and low external component count make the TD9054 ideally suited for portable applications. Furthermore, the TD9054 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 TD9054 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
TD9054 Other features include current monitor, under voltage lockout, automatic recharge and charge status pin to indicate charge termination.
