8.2

Push-pull operation (PP)

The IC can be operated in push-pull mode, with slow demagnetization, by wiring OUTH

and OUTL together. The IC must be driven by the IN2 pin, to allow the deadtime function to

properly protect the output stage. IN1 pin sets the phase relation between IN2 and the

output stage (OUTH, OUTL). See Table 14: "Output stage truth table".

8.3

High-side operation

The IC can be operated in high-side mode, with active clamping, by leaving the OUTL pin

unconnected. IC should be driven by the IN1 pin and IN2 pin sets the phase relation

between IN1 and OUTH. See Table 14: "Output stage truth table".
