GND
Active low reset input. When low (to GND), places the Si3460
device into an inactive state. The dc-dc converter is disabled. When
pulled high, the device begins the detection process sequence. The
dc-dc begins to function after a valid R
indicating a valid PD has been detected.
ISENSE is an analog input connected to a current sense resistor for
output current sensing.
At powerup, the voltage on this pin is sensed to configure the clas-
sification level, mid span timing mode, and the device’s restart
behavior when a fault condition is detected. Refer to "4.2. Operating
Mode Configuration" on page 11 and "4.3.9. Status LED Function"
on page 13 for more information. After reading the voltage present
at this pin at powerup, the STATUS pin becomes a digital output
used to control an external LED, which indicates when a detect,
power good, or output fault condition has occurred. A logic low
turns the LED on, and logic high turns the LED off.
