Low-Cost, SOT23, Voltage-Output, High-Side Current-Sense Amplifier ABSOLUTE MAXIMUM RATINGS
VCC, RS+, RS- to GND .. -0.3V to +30V Continuous Power Dissipation (TA = +70°C) OUT to GND .. -0.3V to (VCC + 0.3V) 8-Pin SO (derate 5.88mW/°C above +70°C)... 471mW Output Short-Circuit to VCC or GND ... Continuous SOT23-6 (derate 8.7mW/°C above +70°C)... 696mW Differential Input Voltage (VRS+ - VRS-) ... ±0.3V Operating Temperature Range .. -40°C to +85°C Current into Any Pin... ±20mA Storage Temperature Range .. -65°C to +150°C Lead Temperature (soldering, 10s) .. +300°C Soldering Temperature (reflow) .. +260°C Stresses beyond those 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 beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
