STSPIN958 EN Delay

Have a quick question. What is the delay time from when the EN is pulled high to when the half bridge becomes non Hi-Z? Similar is disable delay time from when the EN is pulled low? I wasn't able to find this information in the data sheet.

We will be operating in single half bridge (parallel) mode if that has any impact. Thanks!

Hello @twjudge and welcome to the ST Community.

Here below the typical value @ Tj = 25°C,
test conditions of Table 3 in the STSPIN958 datasheet, with "maximum slew rate" selected:

  • ENx high to power stage enabled propagation delay: 160 ns
  • ENx low to power stage enabled propagation delay: 240 ns
