LT610616106faTYPICAL APPLICATIONFEATURESAPPLICATIONSDESCRIPTION36V Low Cost High Side Current Sense in a SOT-23The LT®6106 is a versatile high side current sense ampli-fi er. Design fl exibility is provided by the excellent device characteristics: 250μV maximum offset and 40nA maxi-mum input bias current. Gain for each device is set by two resistors and allows for accuracy better than 1%. The LT6106 monitors current via the voltage across an external sense resistor (shunt resistor). Internal circuitry converts input voltage to output current, allowing for a small sense signal on a high common mode voltage to be translated into a ground referenced signal. The low DC offset allows for monitoring very small sense voltages. As a result, a small valued shunt resistor can be used, which minimizes the power loss in the shunt.The wide 2.7V to 44V input voltage range, high accuracy and wide operating temperature range make the LT6106 ideal for automotive, industrial and power management applications. The very low power supply current of the LT6106 also makes it suitable for low power and battery operated applications.■ Gain Confi gurable with Two Resistors■ Low Offset Voltage: 250μV Maximum■ Output Current: 1mA Maximum■ Supply Range: 2.7V to 36V, 44V Absolute Maximum■ Low Input Bias Current: 40nA Maximum■ PSRR: 106dB Minimum■ Low Supply Current: 65μA Typical, V+ = 12V■ Operating Temperature Range: –40°C to 125°C■ Low Profi le (1mm) ThinSOTTM Package■ Current Shunt Measurement■ Battery Monitoring■ Power Management■ Motor Control■ Lamp Monitoring■ Overcurrent and Fault DetectionLT61061kVOUT200mV/A6106 TA01a100Ω3V TO 36VLOAD0.02Ω–+V+V–OUT–IN+IN3V to 36V, 5A Current Sense with AV = 10 , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.ThinSOT is a trademark of Linear Technology Corporation.
