LT6107 High Temperature High Side Current Sense Amp in SOT-23 FEATURES DESCRIPTION n Fully Tested at 55C (MP), 40C (H), The LT 6107 is a versatile high side current sense ampli- 25Cand150C fier designed for operation over a wide temperature range. n Gain Configurable with Two Resistors Design flexibility is provided by the excellent device char- n Low Offset Voltage: 250V Maximum acteristics: 250V maximum offset and 40nA maximum n Output Current: 1mA Maximum input bias current. Gain for each device is set by two n Supply Range: 2.7V to 36V, 44V Absolute Maximum resistors and allows for accuracy better than 1%. n Low Input Bias Current: 40nA Maximum The LT6107 monitors current via the voltage across an n PSRR: 106dB Minimum external sense resistor (shunt resistor). Internal circuitry + n Low Supply Current: 65A Typical, V = 12V converts input voltage to output current, allowing for a TM n Low Profile (1mm) ThinSOT Package small sense signal on a high common mode voltage to be translated into a ground referenced signal. The low DC APPLICATIONS offset allows for monitoring very small sense voltages. As a result, a small valued shunt resistor can be used, which n Current Shunt Measurement minimizes the power loss in the shunt. n Battery Monitoring n Power Management The wide 2.7V to 44V input voltage range, high accuracy n Motor Control and wide operating temperature range make the LT6107 n Lamp Monitoring ideal for automotive, industrial and power management n Overcurrent and Fault Detection applications. The very low power supply current of the LT6107 also makes it suitable for low power and battery All registered trademarks and trademarks are the property of their respective owners. operated applications.
