noted (Note 1). Current entering a pin (sunk by the device) has a positive sign. R
VOLTAGE MONITORING AND PROTECTION − Power Good
CURRENT CONTROL − Current Sense Amplifier (CSAMP)
CURRENT MONITORING AND PROTECTION
1. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC).
2. Guaranteed by design or bench characterization, not production tested.
3. Timing is referenced to the 90% and 10% points, unless otherwise noted.
