SLVS608 – JANUARY 2006
The IGBT driver is provided by the TPS65560. The driver voltage depends on VCC. TPS65560 has a mask filter
as shown in Figure 8. The mask does not have hysteresis; therefore, there is no wait time from CHG forcing Low
after FULL CHARGE to F_ON turning High.
Figure 8. IGBT Timing Diagram
TPS65560 provides four protection mechanisms: max on time, max off time, thermal disable, and overcurrent
shutdown.
To prevent a condition such as pulling current from a poor power source (i.e., an almost empty battery), and
never reaching peak current, the TPS65560 provides a maximum ON time function. If the ON time exceeds tMAX,
the TPS5560 is forced OFF regardless of I(PEAK) detection.
To prevent a condition such as never increasing the voltage at the SW pin when the internal FET is OFF, the
TPS65560 provides a maximum OFF time function. If the OFF time exceeds tMIN, the TPS65560 is forced ON
regardless of V(ZERO) detection.
Once the TPS65560 die temperature reaches 160
°C, all functions stop. Once the die cools below 160°C, the
TPS65560 restarts charging if CHG remains high during the entire overtemperature condition.
The TPS65560 provides an overvoltage monitor function of the SW pin. The TPS65560 is latched off if the
This function protects against short-circuits on the primary side of the transformer. A short-circuit of the primary
side shorts the battery voltage to GND. SW pin can damage the device if not protected.
