Unsuccessful power-up on STM6601

PB detection on falling edge.

Internal pull-down resistor 300 k

Ω is connected to PSHOLD input during power-up.

PSHOLD signal is ignored during tON_BLANK. When tON_BLANK expires, the level of the PSHOLD signal is not high therefore

the EN signal goes low. Even releasing the PB button after the tON_BLANK will not prevent this.

INT signal is held high during power-up (i.e. until tON_BLANK expires in the case of the STM6601).

VCC is considered VCC > VTH+.
