Voltages relative to V SS .
Specification applicable during charge cycle with T A = 0 ° C to +70 ° C.
One time slot out of every 16 available slots gets a Cell Test.
One time slot out of every 32 available time slots gets a charge pulse.
0.48 seconds is one charge time slot. A complete cycle of 4 time slots (one charge time slot per cell) is 1.92 sec.
V THM-MIN, V THM-MAX, and V THM-STOP are fixed ratios of V DD. Their ranges never overlap.
I MTST current is applied as a source current and as a sink current within 5ms after power-up.
