ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Characteristics noted under conditions of 7.0 V

≤ VPWR ≤ 18 V, -40°C ≤ TC ≤ 125°C, unless otherwise noted. Where

applicable, typical values reflect the parameter’s approximate average value with VPWR = 14 V, TA = 25°C.

Notes

Device is functional provided TJ is less than 150°C. Some table parameters may be out of specification.

Over-voltage thresholds minimum and maximum include hysteresis.

Under-voltage thresholds minimum and maximum include hysteresis, for disabling outputs only, RESET based on VCC under-voltage

This parameter is guaranteed by design, however is not production tested.

10.

Output fault detect thresholds are the same for output open and shorts.
