Hi team,
Depending on the model, the comparator may not be used.
My customer wants to connect the CMPREF pin to GND to reduce power consumption.(CMPIN=VOUT)
Is there any problem?
Sincerely.
Kengo.

Kengo,
As Patrick advises here, the datasheet advises that the preferred connection is pulled-up to supply with a 10kΩ. However, this device has an open drain output. Therefore, shorting the ALERT pin to GND should be fine, as a mosfet typically has high impedance from gate to drain and gate to source. If the gate to the comparator's output is triggered, you would just have a short from the drain to the source, which would both be at the ground potential.
