NAME
FUNCTION
21
ZC_EN
Zero-Current-Detection Enable Logic Input. Referenced to DGND. Connect ZC_EN to a logic high to
enable the zero-current detection circuitry. Connect ZC_EN to a logic low to disable this function.
22
EN
ON/OFF Control-Logic Input. Referenced to DGND. Connect to a logic high to enable the device.
Connect to a logic low to disable the device and reset a latched-off condition.
23
V
DIG
Digital Supply Voltage. V
DIG
is the supply voltage for the internal digital logic circuity. EN, LATCH,
CLASS, DET_DIS, DCA, and ZC_EN input logic thresholds are automatically scaled to the voltage on
V
DIG
. See the Typical Application Circuit for proper filtering.
24
CLASS
Classification Enable Digital Input. Connect to DGND to disable the classification function. Connect to
V
DIG
to enable the classification function.
DET_DIS
PD Detection Disable Logic Input. When DET_DIS is connected to a logic high, the part skips the
detection and classification (regardless of the status of CLASS) phases and powers on immediately
after EN = high (MAX5922B/MAX5922C only).
25
DCA
Detection Collision Avoidance Logic Input. Connect to a logic high to activate the detection collision
avoidance circuitry for midspan system. Connect to DGND to disable this function. (MAX5922A only).
See the Detection Collision Avoidance section.
