Quad Network Power Controller
for Power-Over-LAN
6 _______________________________________________________________________________________
Note 1: GATE_ is internally clamped to 11.4V above V
EE
. Driving GATE_ higher than 11.4V above V
EE
may damage the device.
Note 2: Default values. The charge/discharge currents are programmable through the serial interface (see the Register Map and
Description section).
Note 3: Default values. The current-limit thresholds are programmed through the I
2
C-compatible serial interface (see the Register
Map and Description section).
Note 4: This is the default value. Threshold can be programmed through serial interface R23h[2:0].
Note 5: AC disconnect works only if V

OUT_1
, V

represent the voltage at OUT_ and the current
at DET_ during phase 1 and 2 of the detection.
Note 8: Default values. The startup and fault times can be also programmed through the I
2
C serial interface (see the Register Map
and Description section).
Note 9: Guaranteed by design. Not subject to production testing.
