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.
3.
θJA 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.
4. For
θJC, the "case temp" location is the center of the exposed metal pad on the package underside.
5. The device junction temperature should be kept below 150oC. Thermal shut-down circuitry turns off the device if junction temperature exceeds
+150oC typically.
Electrical Specifications
VCC = 12V, TA = -20oC to +85oC, unless otherwise noted. Typical values are at TA = 25oC. EN1 = EN2 = H,
LLC1 = LLC2 = L, ENT1 = ENT2 = L, DCL = L, DSQIN1 = DSQIN2 = L, Iout = 12mA, unless otherwise noted.
See software description section for I2C access to the system.
