LTC6101 - High Voltage, High-Side Current Sense Amplifier in SOT-23
The LTC6101 operates on supplies from 4V to 60V and LTC6101HV operates on supplies from 5V to 100V. The LTC6101 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 the LTC6101 ideal for a large array of applications from automotive to industrial and power management. A maximum input sense voltage of 500mV allows a wide range of currents to be monitored. The fast response makes the LTC6101 the perfect choice for load current warnings and shutoff protection control. With very low supply current, the LTC6101 is suitable for power sensitive applications.
The LTC6101 is available in 5-lead SOT-23 and 8-lead MSOP packages.
