NOTES

120 kΩ resistor from current sense voltage to VCS pin.

2Applies to 4.2 V, 8.4 V, 12.6 V and 16.8 V options. Includes all error from offset voltage, bias current, resistor divider and voltage reference.

3Does not include attenuation of input resistor divider for ADP3810.

40.1 µF load capacitor required for reference operation.

5Full scale is the programmed final battery voltage: 4.2 V, 8.4 V, 12.6 V or 16.8 V for the ADP3810 or 2.0 V at V SENSE for the ADP3811.

All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.

Specifications subject to change without notice.
