RE: DRV8870: Motor does not work with external capacitor at OUT1 and OUT2

Hi Kaizawa-san,

1. Yes, there is a restriction. If the capacitor causes the current to increase above 3.7A for typically 1.5us, the OCP circuit may activate.
2. The mechanism is typically OCP. This can be confirmed by measuring the time between output pulses. If the output is inactive for approximately 3ms, it is an OCP event.

A solution is to lower the capacitor value.
