Hi Team, seeking some clarification.
Checking the TPIC44H01 datasheet and noticed that the OVLO would set it at a minimum of 27.5V but the VPWR should survive up to 40V.
First we want to know if this feature can be disabled by any means.
If it cannot be done, we want to know if we can lower the VPWR voltage to 24V by Zener diode or a regulator and then rely on the charge pump to deliver the necessarily high gate voltage to turn on the MOSFETs.
We are using logic level VGS MOSFETs for this design so it should not be difficult to turn on. Will this modification causes other issues? (OVDS or the internal zener diode clamp?)
Hoping for you assistance.
