DRV8876: PH/EN Control Mode is not selected

Part Number: DRV8876

Hello everyone,

I'm using the drv8876 stand-alone in following configuration of PH/EN Control mode:

in the follwiing schematics I show you my design:

The DRV8876 should work from "power on" in PH/EN Mode.
I use the PH/EN as I have only the PWM signal from another device  .

* I tied pmode=GND (to select the PH/EN mode).
* I tied  nSleep=High  (Out1 and Out2 enabled)


The problem is that the outputs (out1 and out2)  of DRB8876 wont work, if I'm tying nSleep to +5V.
I think its because nSleep needs an low pulse for selecting the pMode Signal ?
So I put an R1/C19 combination  to nSleep to generate an low pulse to nSleep after power on. Put this is only for test purposes.

Is there another way to select PH/EN-Mode from power on, when I have no possibilty to change state of nSleep-Pin afterwards?

thank you in advance
