NOTES

1All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.

2Including I

BSTQ quiescent current.

3The signal source driving the pin must have 70

µA (typ) pull-down strength to make a high-to-low transient, and 20 µA (typ) pull-up strength to make a low-to-high

transient. The pin does not represent load (<100 nA) in static low (<0.8 V) and static high (>2.0 V) logic states (see TPC 3.) The pin can be driven with standard

TTL logic level source.

4Guaranteed by characterization.

5For propagation delays, tpdh refers to the specified signal going high, tpdl refers to it going low.

6Propagation delay measured until DRVL begins its transition.

7The turn-on of DRVL is initiated after IN goes low by either V

SW crossing a ~1.6 V threshold or by expiration of t SWTO.
