ELECTRICAL CHARACTERISTICS (continued)

VDD, CLASS, DET, T2P and RTN voltages are referred to VSS, and all other pin voltages are

referred to GND, GND and RTN are shorted together. VDD – VSS = 48V, VSS = 0V; RDET = 24.9kΩ,

RCLASS =41.2Ω. TJ = -40°C to +125°C, typical values are tested at TJ = 25C, unless otherwise

noted.
