Static characteristics

Table 10.

Static characteristics

Tvj = −40 °C to +150 °C; VBAT = 4.5 V to 28 V; VBAT > VV1; VBAT > VV2; R(CANH-CANL) = 45 Ω to 65 Ω; all voltages are defined

with respect to ground; positive currents flow in the IC; typical values are given at VBAT = 14 V; unless otherwise specified.
