DRV8844 half bridge PWM utilization

Other Parts Discussed in Thread: DRV8844

Hello,

I need to use two PWM bridges to control a solenoid, in order to get the maximum power.

I'll use the DRV8844 chip.

In the datasheet, it is always shown that OUT1 and OUT2 make one bridge, and OUT3 with OUT4 make a second bridge.

However, it is written that the four half bridges are independent, so I think I can use OUT1 and OUT2 in parallel for the first solenoid pad, and OUT3 and OUT4 in parallel for the second pad (so OUT1 and OUT3 make one bridge for instance, and OUT2 with OUT4 make the second bridge). This gives an clearer layout.

Please can you confirm that?

Thank you,

Best regards
