Junction Temperature Calculation: T J = TA + (PD x θJA). Note B. The above numbers for θ JC are maximums for the limiting thermal resistance of the package in a standard mount- ing configuration. The θ JA numbers are meant to be guidelines for the thermal performance of the device/pc- board system. All of the above assume no ambient airflow. 2.625 3.500 2.375 1.500 ±0.6 100 DC Sense Inputs Section V PIN 1 = 0.95 x VREF V PIN 1 = 0.60 x VREF V PIN 1 = 0.95 x VREF V PIN 1 = 0.60 x VREF V SENSE = 1.5V to 3.5V +V IN = 4.5V to 35V Overvoltage Threshold Undervoltage Threshold Input Bias Current Threshold Supply Rejection 4.5V to 35V 5.0V to 35V 1.5V to 2.45V ±5% to ±40% 0 to 10mA Supply Voltage Range ±25% Maximum Fault Window (Note 3) .............. ±40% Maximum Fault Window ...........................

RECOMMENDED OPERATING CONDITIONS (Note 2) ELECTRICAL CHARACTERISTICS (Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1548 with -55 °C ≤ T A ≤ 125 °C, SG2548 with -25 °C ≤ T A ≤ 85°C, SG3548 with 0°C ≤ TA ≤ 70°C, and +VIN = 15V. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
