NOTES

'20 kQ resistor from current sense voltage to Vcs pin.

'Applies 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.

'Does not include attenuation of input resistor divider for ADP38 I O.

'0.1 lAPload capacitor required for reference operation.

'Full scale is the programmed final battery voltage: 4.2 V, 8.4 V, 12.6 V or 16.8 V for the ADP38 I 0 or 2.0 V at V SENSEfor the ADP381 I.

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

Specifications subject to change without notice.
