ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VAGND = 32V to 60V, VEE = 0V, VDD to VDGND = +3.3V, all voltages are referenced to VEE, unless otherwise noted. Typical values are at
VAGND = +48V, VDGND = +48V, VDD = (VDGND + 3.3V), TA = +25°C. Currents are positive when entering the pin and negative other-
wise.) (Note 2)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
(Voltages referenced to VEE, unless otherwise noted.)
AGND, DGND, DET_, VDD, RESET, A3–A0, SHD_, OSC,
SCL, SDAIN, AUTO .............................................-0.3V to +80V
OUT_........................................................-12V to (AGND + 0.3V)
GATE_ (internally clamped) (Note 1) ..................-0.3V to +11.4V
SENSE_ ..................................................................-0.3V to +24V
VDD, RESET, MIDSPAN, A3–A0, SHD_, OSC, SCL,
SDAIN and AUTO to DGND ..................................-0.3V to +7V
INT and SDAOUT to DGND....................................-0.3V to +12V
Maximum Current into INT, SDAOUT, DET_ .......................80mA
Maximum Power Dissipation (TA = +70°C)
36-Pin SSOP (derate 17.4mW/°C above +70°C) .....1388.9mW
Operating Temperature Ranges:
MAX5965A/MAX5965B_EAX ...…………………-40°C to +85°C
MAX5965A/MAX5965B_UAX ...............................0°C to +85°C
Storage Temperature Range .............................-65°C to +150°C
Junction Temperature ......................................................+150°C
Lead Temperature (soldering, 10s) .................................+300°C
Soldering Temperature (reflow) .......................................+260°C
Note 1: GATE_ is internally clamped to 11.4V above VEE. Driving GATE_ higher than 11.4V above VEE may damage the device.
