LTC6101ACS5#TRMPBF

LTC6101 is versatile, high voltage, high side current sense amplifier. It 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. Low DC offset allows the use of a small shunt resistor and large gain-setting resistors. As a result, power loss in the shunt is reduced. The wide operating supply range and high accuracy make this device ideal for a large array of applications from automotive to industrial and power management. The fast response makes this as the perfect choice for load current warnings and shutoff protection control. With very low supply current, it is suitable for power sensitive applications. Applications include current shunt measurement, battery monitoring, remote sensing and power management.
