LTC6101HV operates on supplies from 5V to 100V. n
Gain Configurable with 2 Resistors
The LTC6101 monitors current via the voltage across an n Low Input Bias Current: 170nA Max external sense resistor (shunt resistor). Internal circuitry n PSRR: 118dB Min converts input voltage to output current, allowing for a n Output Current: 1mA Max small sense signal on a high common mode voltage to n Low Supply Current: 250μA, V S = 12V be translated into a ground referenced signal. Low DC n Specified Temperature Range: –40°C to 125°C offset allows the use of a small shunt resistor and large n Operating Temperature Range: –55°C to 125°C gain-setting resistors. As a result, power loss in the shunt n Package Option for High Voltage Spacing is reduced. n Low Profile (1mm) SOT-23 (ThinSOT™) Package The wide operating supply range and high accuracy make
APPLICATIONS
the LTC6101 ideal for a large array of applications from automotive to industrial and power management. A maxi- n mum input sense voltage of 500mV allows a wide range Current Shunt Measurement n of currents to be monitored. The fast response makes the Battery Monitoring n LTC6101 the perfect choice for load current warnings and Remote Sensing n shutoff protection control. With very low supply current, Power Management the LTC6101 is suitable for power sensitive applications. All registered trademarks and trademarks are the property of their respective owners.
