Note 1: Voltages relative to VSS.
Note 2: Specification does not include CS and STATUS pin currents.
Note 3: STATUS pin is active high.
Note 4: Specification is guaranteed by design.
Note 5: Specification applicable during charge cycle with TA = 0°C to +70°C.
Note 6: 50mV overdrive while connected to a pMOS transistor (such as ZXM62P02 from Zetex).
Note 7: VBAT-MAX1 and VBAT-MAX1 ranges never overlap.
Note 8: VTHM-MIN, VTHM-MAX, and VTHM-STOP are fixed ratios of VDD. Their ranges never overlap.
Note 9: Maximum allowable leakage on TMR to maintain SUSPEND state.
