Controller with Integrated MOSFET
ELECTRICAL CHARACTERISTICS (continued)
(VAGND - VEE = 32V to 60V, TA = -40NC to +85NC, all voltages are referenced to VEE, unless otherwise noted. Typical values are at
VAGND - VEE = 54V, TA = +25NC. Currents are positive when entering the pin and negative otherwise.) (Note 2)
