Its SOT package and low external component count make the TCS6035 ideally suited for portable applications.

Furthermore, the TCS6035is specifically designed to work within USB power specifications.No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture.

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 TCS6035automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.

When the input supply (wall adapter or USB supply) is removed, the TCS6035 automatically enters a low current state, dropping the battery drain current to less than 2μA. The TCS6035 can be put into shutdown mode, reducing the supply current to 25μA. Other features include charge current monitor, undervoltage lockout, automatic recharge, and a status pin to indicate charge termination and the presence of an input voltage.
