Oscillator Off (Notes 2, 3, and 4)
NOTES: 1. For supply voltages restricted to 2.5 to 2.9 V and an ambient temperature range of –10 to 60°C, Output C has a guaranteed ON resistance range of 23
to 44 Ω .
2. The total supply current drain for the keep–alive oscillator, voltage multiplier, and regulator is approximately 250 µA.
3. When the Mode pin is tied high, bit C6 must be programmed to a 0 for minimum supply current drain. Otherwise, if C6 = 1, the current drain is approximately
8 µA for a 1.8 V supply and approximately 40 µA for a 3.6 V supply. This restriction on bit C6 does not apply when the Mode pin is tied low.
4. To ensure minimum standby supply current drain, the voltage potential at the Cmult pin must not be allowed to fall below the potential at the Vpos pins.
See discussion in Section 5E under Cmult.
