Maximum Junction Temperature . . . . . . . . . . . . . . . . . . . . . . . 150°C
Maximum Storage Temperature Range . . . . . . . . . . . -40°C to 150°C
For recommended soldering conditions, see Tech Brief TB389.
NOTE: The device junction temperature should be kept below
150°C. Thermal shut-down circuitry turns off the device if junction
temperature exceeds +150°C typically.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. θ JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
2. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
VCC = 12V, T A = -20°C to +85°C, unless otherwise noted. Typical values are at T A = 25°C. EN = H, LLC = L,
ENT = L, DCL = L, DSQIN = L, Iout = 12mA, unless otherwise noted. See software description section for I 2 C
