DC CHARACTERISTICS (CONTINUED)

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.
