Solenoid is Pulled High to 24V, Freewheels Low to a Schottky Below Ground

Sep 7th 2007
The large input common mode range of the LT6105 makes it suitable for monitoring currents in quarter, half and full bridge inductive load driving applications.This circuit shows an example of a quarter bridge. The MOSFET pulls down on the bottom of the solenoid to increase solenoid current. It lets go to decrease current, and ...

LT6105 Current Sense Amplifier Monitors Both +15V and -15V Supplies

Greg Zimmer - Senior Product Marketing Engineer Sep 7th 2007
The input common mode range of the LT6105 also makes it suitable for monitoring either positive or negative supplies. The circuit below shows one LT6105 applied as a simple positive supply monitor, and another LT6105 as a simple negative supply monitor. Note that the schematics are practically identical and both have outputs ...

The LT6105 Can Monitor the Current of Either Positive or Negative Supplies, Without a Schematic Change.

Sep 7th 2007
Positive or negative current flow is measured by just swapping inputs, -IN connected to most negative side of sense resistor. +IN is connected to most positive side of sense resistor. ...
