Part Number: TPS92692-Q1

Hello,

In the device functional modes table 1, there is the Vref pin shot to ground fault description.
However, the action of Vref pin short is same with UVLO.
Could you please let me know the correct Action description of Vref pin short to ground?

Best Regards,
Ryuji

Hello Ryuji-san,

From the product line:

"The VREF pin short to ground sets the VREF POR and forces the part in standby mode. The standby mode is same as the UVLO state, where GATE and PDRV are disabled and SS and COMP capacitors are discharged. The nFLT pin is in high-impedance state.

Basically, ignore the first sentence and the rest is true."

Regards,

Clint
