In the presence of a common-mode voltage greater than 5 V, if the shunt voltage applied to the comparator does not exceed the threshold (i.e., the bulb is switched
on but does not draw current), then the device will indicate a failure.
2
At V
= 13.5 V, the differential input threshold voltage is typically 1.75 mV. With an increase of V
, the threshold voltage, V
INDIFF
, will change as well.
Power supply sensitivity of 50% means that when the power supply voltage V
S
increases by 10%, the threshold voltage V
INDIFF
centage value: 5%.

C.
4
T his current source is used to test the lamp when it is switched off (cold lamp test).
5
If the voltage at the input from the fuse (Pin 6 or 19) does not exceed the threshold voltage, then the output will indicate a failure.
6
When the Chip Enable is open-circuited, the chip is disabled.
7
Shorting V
to ground will cause the device to stop operating for that period. However, the device will not suffer any damage.
8
At this voltage, or above, the internal power supply and the power output V
will be shut off.
9
Below the minimum voltage, the circuit will shut down. Above the maximum, the circuit will be on if enabled.
All min and max specifications are guaranteed, although only those marked in
boldface
are tested on all production units at final test.
Specifications subject to change without notice.
