FUNCTION
Linear Current-Source Output
Input Voltage for Powering Charger
Chip Power Supply. 5.4V linear regulator output from DCIN.
Voltage-Regulation-Loop Compensation Point
Current-Regulation-Loop Compensation Point
Current-Range Selector. Tying SEL to VL sets a 4A full-scale current. Leaving SEL open
sets a 2A full-scale current. Tying SEL to AGND sets a 1A full-scale current.
