Note 1: Battery voltage temperature coefficient is the worst case voltage change divided by the total temperature

range.

2: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are

tested for load regulation in the load range from 100 μA to 500 mA. Changes in output voltage due to heat-

ing effects are covered by the thermal regulation specification.

3: Dropout voltage is defined as the input to battery output differential at which the battery voltage drops 2%

below its nominal value measured at 1V differential.

4: Ground pin current is the charger quiescent current plus pass transistor base current. The total current

drawn from the supply is the sum of the load current plus the ground pin current.

5: VEN is the voltage externally applied to devices with the EN (enable) input pin. MSOP-8 (MM) and SOIC-8

(M) packages only.

6: Thermal regulation is the change in battery voltage at a time “t” after a change in power dissipation is

applied, excluding load or line regulation effects. Specifications are for a 500 mA load pulse at VIN = 16V

for t = 10 ms.
