A1
program device SMBus base address. These inputs have internal pull-up
resistor to V

A2
SMBus Address Select Pins: Connect to ground or leave open in order to
in the STAT[A/B] and/or CS registers. This pin requires an external pull-up
17
accuracy is determined by the specification for V

/INT
Interrupt Output: Open-drain, active-low. Asserted whenever a power fault
is detected if the INTMSK bit (CS Register Bit D[3]) is a logical "0". This
output is cleared by performing an "echo reset" to the appropriate fault bit(s)

RFILTER[A&B]
Connecting this pin to GND through a 110kΩ, 1% resistor will provide a
significant improvement in timeout duration accuracy for slow overcurrent
faults on Slot A and Slot B. If left floating (NC), overcurrent timeout duration
