LTC6104 Description

The LTC6104 is a versatile, high voltage, high side, bidirectional current sense amplifier. Design flexibility is provided by the excellent device characteristics: ±450µV maximum offset and only 520µA of current consumption (typical at 12V). The LTC6104 operates on supplies from 4V to 60V.

The LTC6104 monitors bi-directional current via the voltage across an external sense resistor (shunt resistor). This sense voltage is then translated into a ground referenced signal. Gain is set with three external resistors and can be separately configured for both directions. 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 minimal.

The wide operating supply range and high accuracy make the LTC6104 ideal for a wide variety of automotive, industrial and power management applications. A maximum input sense voltage of 500mV allows a wide range of currents to be monitored. The fast response makes the LTC6104 the perfect choice for load current warnings and shutoff protection control. With very low supply current, the LTC6104 is suitable for power sensitive applications.

The LTC6104 is available in an 8-lead MSOP package.
