7.6 Typical Characteristics

At VCC = 16 V, AGND = PGND = 0 V, VINAC = 3 V, VSENSE = 6 V, HVSEN = 3 V, PHB = 5 V, RTSET = 133 kΩ;

all voltages are with respect to GND, all outputs unloaded, TJ = TA = +25 °C, and currents are positive into and

negative out of the specified terminal, unless otherwise noted.
