LIN transceiver with integrated voltage regulator
Table 6.
Static characteristics …continued
VBAT = 5.5 V to 28 V; Tvj = −40 °C to +150 °C; RL(LIN-VBAT) = 500 Ω; all voltages are defined with respect to ground; positive
currents flow into the IC; typical values are given at VBAT = 12 V; unless otherwise specified.
