Hello Team,
My customer uses the H-Bridge with the following parameters:
VM: 10V
Max. Strom: 450mA
Mode: PH/EN Control Mode
Logic-Level: 3.3V
nSLEEP: controlled with MCU
PWM-Freuqenz: 30kHz
As long he is driving the H-Bridge with 20-100% duty cycle the bridge works as expected.
When he is driving the bridge with 10% duty cycle the drive shuts down after 1.2ms
nSLEEP was at logic high for all his tests and the EN pin was triggered with the PWM Signal.
Do you know the route cause for this behavior. Does the device turn into auto sleep mode ?
Thank you
Jan
