Table 102. VGEN2 Electrical Characteristics

All parameters are specified at TA = -40 to 85 °C, VIN = 3.6 V, VIN1 = 3.0 V, VGEN2[3:0] = 1111, IGEN2 = 10 mA, typical external

component values, unless otherwise noted. Typical values are characterized at VIN = 3.6V, VIN1 = 3.0 V, VGEN2[3:0] = 1111,

IGEN2 = 10mA and 25°C, unless otherwise noted.
