Diagnosis
8.5
Electrical Characteristics
Unless otherwise specified: V_S = 7 V to 18 V, V_DD = 3.8 V to 5.5 V, T_j = -40 °C to +150 °C
Typical values: V_S = 13.5 V, V_DD= 4.3 V, T_j = 25 °C
Typical resistive loads connected to the outputs (unless otherwise specified):
39 mΩ channels: R_L = 6.8 Ω (33 Ω when LGCR.LEDn = “1”)
Measurement setup used for k_ILIS (unless otherwise specified):
When I_L ≤ 1.3 A all channels are ON at the same time with equal I_L
When I_L ≥ 2.0 A only the measured channel is ON, all other channels have I_L = 0
