Electrical Characteristics
Unless otherwise specified: VS = 7 V to 18 V, VDD = 3.8 V to 5.5 V, Tj = -40 °C to +150 °C
typical values: VS = 13.5 V, VDD = 4.3 V, Tj = 25 °C
Typical resistive loads connected to the outputs (unless otherwise specified):
39 mΩ channels: RL = 6.8 Ω (33 Ω when LGCR.LEDn = “1”)
