DRV8718-Q1: When the high-side driver is activated, the voltage of SH is higher than that of VM.

Tool/software:

1. Hi expert Currently, in the project, DRV8718 is being used. When the half-bridge is used as the high side and the battery voltage is 13.5V, there is a voltage at the upper transistor's drive end even without a drive signal, close to 14.5V, and the SH voltage is also 14.5V. After providing a drive signal, the voltage at the upper transistor's drive end is higher than 14.5V, while the SH voltage is 13.5V. When a 60K resistor is connected to the SH terminal, the SH voltage becomes 6.5V when no drive signal is applied. I would like to ask about the cause of this situation. I couldn't find any relevant description in the manual.
