Charging Sequence Chart Start/Stop Charging The TPS65563A has an enable/disable pin for charging (CHG). The only way to start charging is to input a high-level signal into CHG (see A and C in Figure 2).

TPS65563A SLVS858A – JULY 2008 – REVISED AUGUST 2008......................................................................................................................................................... www.ti.com In Figure 5, ON time is almost the same period in every switch cycle. But the current at SW always starts from negative value because of the Trr of the diode. Because of this, ON time depends on Trr. ON time is calculated by Equation 1.

TPS65563A www.ti.com......................................................................................................................................................... SLVS858A – JULY 2008 – REVISED AUGUST 2008 Typical usages of this function are: • Setting the peak charging currents based on the battery voltage. The easiest way is to connect a resistive divider with battery voltage. This saves battery life. • Reducing peak current at the primary side when the system powers a zoom-lens motor.
