Adjustable Overvoltage Protector
with High Accuracy
ABSOLUTE MAXIMUM RATINGS
(All voltages referenced to GND.)
IN ............................................................................-0.3V to +30V
OUT .............................................................-0.3V to (VIN + 0.3V)
OVLO........................................................................-0.3V to +6V
Continuous IN Current .............................................................1A
Peak IN Current (Note 1)..........................................................5A
Continuous OVLO Current ...................................................50µA
Continuous Power Dissipation (TA = +70°C)
8-Pin TDFN (derate 11.9mW/°C above +70°C) ...........954mW
Package Junction-to-Ambient Thermal Resistance (θJA)
(Note 2) .....................................................................83.9°C/W
Package Junction-to-Case Thermal Resistance (θJC)
(Note 2) ........................................................................37°C/W
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +150°C

Note 1: Limited by thermal shutdown.
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
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.
ELECTRICAL CHARACTERISTICS
(VIN = +2.2V to +28V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VIN = +5.0V and TA = +25°C.) (Note 3)
