() The VIH is internally clamped at 6V about. It is possible to connect this pin to an higher voltage via an external resistor calculated to not

exceed 10 mA at the input pin.

note 1: The Nominal Current is the current at Tc = 85

oC for battery voltage of 13V which produces a voltage drop of 0.5 V

note 2: IOL(off) = (VCC -VOL)/ROL (see figure)

note 3: t1(on): minimum open load duration which acctivates the status output

t1(off): minimum load recovery time which desactivates the status output

t2(off): minimum on time after thermal shut down which desactivates status output

tpovl tpol: ISO definition (see figure)
