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

Gate driver voltage flexibility
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.
