Product Overview

LT6105 is a micropower, precision current sense amplifier with a very wide input common mode range. The LT6105 monitors unidirectional current via the voltage across an external sense resistor. The input common mode range extends from –0.3V to 44V, with respect to the negative supply voltage (V–). This allows the LT6105 to operate as a high side current sense monitor or a low side current sense monitor. It also allows the LT6105 to monitor current on a negative supply voltage, as well as continuously monitor a battery from full charge to depletion. The inputs of LT6105 can withstand differential voltages up to ±44V, which makes it ideal for monitoring a fuse or MOSFET switch. When V+ is powered down, the sense pins are biased off. This prevents loading of the monitored circuit, irrespective of the sense voltage. Applications include high side or low side current sensing, current monitoring on positive or negative supply voltages, battery monitoring, fuse/MOSFET monitoring.
  • Suitable for use in automotive, power management and portable test/measurement systems
  • Very wide, Over-the-Top®, input common mode range
  • Extends 44V above V– (independent of V+), extends –0.3V below V–
  • Wide power supply range from 2.85V to 36V, operating current of 150μA
  • Input offset voltage of 0.3mV at VSENSE = 5mV, TA = 25°C
  • Gain configurable with external resistors
  • Slew rate of 2V/μs (VSENSE = 5mV to 150mV, AV = 50V/V, RIN = 400 ohm, TA = 25°C)
  • Full-scale output current of 1mA minimum
  • Sense input current when powered down is 1nA
  • 8-lead plastic MS8 package, -40°C to 85°C specified temperature range
