ELECTRICAL CHARACTERISTICS
Power Dissipation
Loop resistance = 0 to ∞ unless otherwise noted (not including fuse resistors), 2 x 50 Ω fuse resistors,
BATL = –36 V, BATH = –65 V, VCC = +5 V. For power dissipation measurements, DC-feed conditions
are as follows:










Power Dissipation
Normal Polarity
Power Supply Currents
ILA (Active mode current limit) = 25 mA (IRSN = 50 µ A)
RFD (Feed resistance) = 500 Ω
VAS (Anti-sat activate voltage) = 10 V
VAPP (Apparent Battery Voltage) = 48 V
RTMG1 = RTMG2 (Thermal management resistors) = 1 k Ω
