Hi team, customer use DRV8243S-Q1LEVM to do OCP test. but they find that OLA is asserted mistakenly when OCP removed, which is presented only in PH/EN mode and is normal in PWM mode. could you help me to find the reason of OLA fault?
the test load is inductive: 5ohms, 1.66mH
out 1 and out 2 both of PH/EN and PWM mode:
out 1 : high for 200ms, high for 800ms, low for 200ms, high for 800ms
out 2: low for 200ms, high for 800ms, high for 200ms, high for 800ms
