Electrical Characteristics

(1)(2) (continued)

Limits in standard typeface are for TA = 25°C, and limits in boldface type apply over the full operating temperature range (-

30°C to +85°C). Unless otherwise specified: VIN = 3.6V; VHWEN = VIN; VPWM = 0V;VDxA = VDxB = VDxC = 0.4V; GroupA = GroupB

= GroupC = Fullscale Current; ENxA, ENxB, ENxC Bits = “1”; 53A, 62A Bits = "0"; C1 = C2 = CIN= COUT= 1.0µF.
