Parallel output operation

For applications demanding high driving current capability (over 4.5 A provided by the single branch), the

RHRPM4424 allows the two drivers to be in parallel to reach the highest current, up to 9 A. This configuration is

depicted in Figure 6. Parallel output connection where PWM_1 and PWM_2 and OUTH_x and OUTL_x are tied

together. The matching of internal propagation delays guarantees that the two drivers switch on and off

simultaneously.

Gate driver voltage flexibility

The RHRPM4424 allows the user to select the gate drive voltage so to optimize the efficiency of the application.

The low-side MOSFET driving voltage depends on the voltage applied to VCC and can range from 4.65 V to 18 V.
