PM8834 Device description and operation

4.3 Parallel output operation
For applications demanding high driving current capability (in excess of the 4 A provided by
the single section), the PM8834 allows paralleling the operation of the two drivers in order to
reach higher current, up to 8 A.This configuration is depicted in Figure 4 where both PWM_1
and PWM_2 and OUT_1 and OUT_2 are tied together. The matching of internal propagation
delays guarantees that the two drivers are switched on and off simultaneously.

4.4 Gate driver voltage flexibility
The PM8834 allows the user to freely select the gate drive voltage in order to optimize the
efficiency of the application. The low-side MOSFET driving voltage depends on the voltage
applied to VCC and can range between 5 V to 18 V.
