All voltages referenced to AGND pin.
V CIN is equivalent to V AUX when V AUX is greater than V TRIP , otherwise V CIN is equivalent to V BATT+ .
Supply-current specification is only for current drain of the IC and does not include cell-charge current, load-supply cur-
rent, or any external resistor bias currents. The only exception is I SLEEP , which does account for complete current drain of
the lithium cell during low-battery conditions.
Below this voltage, the input is guaranteed to be logic-low.
Operating from 3.3V ±10%.
Above this voltage, the input is guaranteed to be logic-high.
Assumes an R SNS value of 0.05 ? .
Relative to V CV .
With recommended application circuit.
Includes complete package resistance.
This specification is from the rising or falling edge of ENS to the closure of the switch and includes whatever delay is in the
internal logic and FET drivers.
Applies to charger.
Multiply these values by C BIAS voltage to get value in volts. Recommended value of resistor in divider network is 10k ? ±1%.
Tolerance includes tolerances of internal resistance and C BIAS voltage.
Applies to memory buck regulator.
