Table 103. VGEN3 Electrical Characteristics

All parameters are specified at TA = -40 to 85 °C, VIN = 3.6 V, VIN2 = 3.6 V, VGEN3[3:0] = 1111, IGEN3 = 10 mA, typical external

component values, unless otherwise noted. Typical values are characterized at VIN = 3.6 V, VIN2 = 3.6 V, VGEN3[3:0] = 1111,

IGEN3 = 10 mA, and 25 °C, unless otherwise noted.
