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]

Conditions
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.
