†Notice: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at those or any other conditions

above those indicated in the operational listings of this specification is not implied. Exposure to maximum

rating conditions for extended periods may affect device reliability.

DC CHARACTERISTICS

Electrical Specifications: Unless otherwise indicated, all limits apply for VIN =VREG + 0.3V to 6V, TA = -40°C to +85°C.

Typical values are at +25°C, VIN =[VREG (typical) + 1.0V]

Note 1:

The value is ensured by design and not production tested.

2:

The maximum available charge current is also limited by the value set at PROG1 input.
