20 / 29 page ![]() Automatic confirmation of power-up + immediate shutdown after PB button press only AN3271 20/29 Doc ID 17933 Rev 2 10 Automatic confirmation of power-up + immediate shutdown after PB button press only If PBOUT is connected to the PSHOLD signal, power for the application is disabled only after pressing the PB button (see Figure 18). This hookup only applies to the STM6601 device. For the STM6600, the PSHOLD state is checked after releasing the PB button. Since PSHOLD is held low by PBOUT, the STM6600 would never start. Figure 18. Automatic power-up confirmation + shutdown after PB button press only Note: This hookup is not suitable for the STM6600. |
