IEEE 802.3af/at-Compliant, Powered Device Interface
Controllers with Integrated 70W High-Power MOSFET
ELECTRICAL CHARACTERISTICS (continued)
(V IN = (V DD - V SS ) = 48V, R DET = 24.9kω, R CLS = 615ω, and R SL = 60.4kω. RTN, WAD, PG, 2EC , WK , and ULP unconnected, all
voltages are referenced to V SS, unless otherwise noted. T A = T J = -40 N C to +85 N C, unless otherwise noted. Typical values are at
T A = +25 N C.) (Note 3)
