Part Number: DRV8874-Q1 Other Parts Discussed in Thread: DRV8242-Q1 Hello Team,
customer see leakage current sinking into OUT pins even when tri-state.
Is there a specification available for this current?
Background: There is a supercap storage…
Part Number: DRV8874-Q1 Other Parts Discussed in Thread: DRV8874 Hello Team, one question from customer:
Is the charge pump active when OUT1 and OUT2 are tri-state (means in-acitvie) ?
Many Thanks

Hi Lance,
I noticed that customer's driving condition is 10A(with a few second?) to ramp up. DRV8874-Q1 is not good device for this load profile. I recommend to move to DRV8243-Q1.
DRV8874-Q1 OCP is 6A min. DRV8243-Q1 is OCP min 12A.
PWM lower frequency…
