Linear Technology LT6100
The LT6100 monitors unidirectional currents via the voltage across an external sense resistor. The LT6100 sense inputs have a voltage range that extends from 4.1V to 48V, and can withstand a differential voltage of the full supply. This makes it possible to monitor the voltage across a MOSFET switch or a fuse.| Part No. | LT6100 |
