ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(VBAT = 13.6V, VDIAG = 0, VOE = 5V, IN1 = IN2 = no connection, RISET = 63.4kΩ, RPU = 10kΩ at ERR, OUT1 and OUT2, TA = -40°C
to +125°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
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.
BAT to GND............................................................-0.3V to +60V
ISET to BAT ...........................................................-2.0V to +0.3V
IN1, IN2 to GND..........-5.0V to the lower of +60V or (VBAT + 1V)
DIAG, OE to GND..................................................-0.3V to +6.0V
OUT1, OUT2, ERR to GND....................................-0.3V to +6.0V
Short-Circuit Duration of OUT1, OUT2, ERR to GND
or to 5.5V (individually)............................................Continuous
Current into Any Pin Except IN1, IN2 ...............................±20mA
Current into IN1, IN2.......................................................±100mA
Continuous Power Dissipation (TA = +70°C)
10-Pin MAX (derate 5.6mW/°C above +70°C) .........444.4mW
Operating Temperature Range .........................-40°C to +125°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +150°C
