NOTES:
4. To ensure best stability of the threshold voltage, a bypass capacitor (ceramic, 0.1
F) should be placed near to the supply terminals.
5. For VDD < 1.6 V, VOUT switches to VBAT regardless of VBAT
6. For details on how to optimize current consumption when using WDI. Refer to detailed description section, watchdog.
