Stresses 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 outside those listed in the operational sections of the specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability. Devices are ESD sensitive. Handling precautions are recommended. RECOMMENDED OPERATING CONDITIONS Temperature Range (Industrial) .......... –40 °C to +85°C (Commercial)............ –5 °C to +70°C VDD Supply Voltage.................................. 2.7V to 5.5V 12VIN Supply Voltage (1)........................ 8.0V to 14.0V VIN.............................................................GND to VDD VOUT.......................................................GND to 15.0V Package Thermal Resistance ( θJA) 28 Lead QFN………………………………….…80 oC/W Moisture Classification Level 1 (MSL 1) per J-STD- 020 Note (1) — Range depends on internal regulator set to 3.6V or 5.5V, see 12VIN specification below.

The resulting value is determined by subtracting Threshold Low from Threshold High (VTH – VTL) while monitoring the FAULT# pin state. Base DC Hysteresis is measured with a 1.25V input. Actual DC Hysteresis is derived from the equation: (VIN/VREF)(Base Hysteresis). For example, if VIN = 2.5V and VREF = 1.25V then Actual DC Hysteresis = (2.5V/1.25V) (0.003V) = 6mV. |
