Part Number: BQ500212A

Can the Sleep and Snooze mode be disabled if I don't need these functions?
If they can be disabled, how should I connect the related pins: SLEEP, SNOOZE, SNOOZE_CAP, SNOOZE_CHG ?

Thanks~

    Hello

    This can be controlled by the LED_Mode pin, see below.

    Unused pins are Open, float.

    NOTE--Pin 45 should be connected to 3.3V.

    •Two LED modes change how sleep & snooze work:
    –LED mode 2, 48.7k ohms Pin 44 to ground—will disable external sleep & snooze timing is controlled internally and device will stay on. NO low power standby.
    –Do not populate Sleep & Snooze RC circuits, 3.3V regulator on all the time.
    –LED mode 9, 133k ohms Pin 44 to ground---snooze timing is external using RC ckt but sleep timing is controlled internally and deice will stay on for sleep. Low Power Standby for no RX present. But NO low power standby for RX present and charge complete.
    –Populate Snooze RC circuit
    –Do not populate Sleep RC ckt
    •For additional information on LED Modes see table 1 in data sheet
