Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
*Junction temperature rating due to power dissipation must also be observed.
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
(VCC = 5V, VBAT = VRS+ = 12V, VSENSE = (VRS+ - VRS-) = 0V, RRSP = RRSN = 500Ω, ROUT = 10kΩ, TA = -40°C to +125°C. Typical
values are at TA = +25°C, unless otherwise noted. See the Typical Application Circuit.) (Note 2)
