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), 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 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.
