3.1 Evaluation Setup

A 300mΩ shunt resistor targets 2.26AAVG charging current, shown in equation 1. The charging current behavior is shown in Figure 3-1.

Equation 1. I P E A K = 1 . 2   V 300   m Ω = 4   A I M I N = 0 . 160   V 300   m Ω = 0 . 53   A I A V G = I P E A K   +   I M I N 2 = 2 . 26   A
