Introduction

AI Translation

The 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.

Gain is configured with external resistors from 1V/V to 100V/V. The input common mode rejection and power supply rejection are in excess of 100dB and the input offset voltage is less than 300μV. A typical slew rate of 2V / μs ensures fast response to unexpected current changes.

The LT6105 can operate from an independent power supply of 2.85V to 36V and draws only 150μA. When V+ is powered down, the sense pins are biased off. This prevents loading of the monitored circuit, irrespective of the sense voltage. The LT6105 is available in a 6 - lead DFN and 8 - lead MSOP package.
