Other Parts Discussed in Thread: DRV8210P
My customer want to use 1.8V to drive VCC of DRV8837C and I understand UVLO may be enabled when VCC<1.8V from below post.
I have several questions. This is urgent so kindly answer by today.
- Can customer use 1.8V±5% (1.71V-1.89V) after the device exit UVLO?
Max value of UVLO falling is 1.7V so they can apply this usage after making sure higher than 1.8V is applied.
- Customer have tried to apply less than 1.7V VCC gradually but they didn't observe UVLO is suddenly activated but observe output gradually decrease at around 1.3V-1.4V. Vise versa, they observe similar behavior when VCC is increased from low voltage. Is this behavior as your expectation? Please share if you have referenceable waveform.
