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. +150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Operation close to +150°C junction may trigger the shutdown of the device even before +150°C, since this number is specified as typical. NOTES: 2. 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. 3. For θ JC, the "case temp" location is the center of the exposed metal pad on the package underside. 4. 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. Electrical Specifications VCC = 12V, TA = -20°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C. EN1 = EN2 = H, VTOP1 = VTOP2 = L, ENT1 = ENT2 = L, DCL = L, DSQIN1 = DSQIN2 = L, IOUT = 12mA, unless otherwise noted. See “ISL6422 Software Description” on page 12 for I2C access to the system.
