Note 1: Adapter Present conditions are tested at VDCIN = 19V and VBATT = 16.8V. Adapter Absent conditions are tested at VDCIN

= 16V, VBATT = 16.8V.

Note 2: Specifications to -40°C are guaranteed by design and not production tested.

Typical Operating Characteristics

(Circuit of Figure 1, VIN = 19V, VCC = VDD = 5V, EN = VCC, TA = +25NC, unless otherwise specified.)
