Voltages relative to V SS .
I MTST current is applied as a source current and as a sink current within 5ms after power-up.
When operating in two-cell-series charge configuration, the DMSEL pin must have less than 50pF of external load capacitance for
proper operation. If the load capacitance is greater than 50pF, a resistor voltage-divider should be used to maintain DMSEL at V DD /2.
Specification applicable during charge cycle with T A = 0 ° C to +70 ° C.
V BAT-MAX1 and V BAT-MAX1 are generated from the same reference. Their ranges never overlap.
V THM-MIN, V THM-MAX, and V THM-STOP are fixed ratios of V DD. Their ranges never overlap.
Tested with I CSOUT = -1mA.
Gain tested with 1mV step with I CSOUT = -1mA.
