Note: 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+.

1. PB detection on falling edge.

2. Internal pull-down resistor 300 kΩ is connected to PSHOLD input during power-up.

3. PSHOLD signal is ignored during tON_BLANK. When tON_BLANK expires, the level of the PSHOLD signal is high therefore the

EN signal remains asserted.
