Current-sensing low-side mosfet driver

The AUIRS is a high side mosfet driver for very low Rdson automotive application. It offers over-current, over-temperature protection and diagnostic. The over-current protection is done by monitoring the Vds voltage, the threshold is programmable by external resistor. The over-temperature protection uses a thermal sensor. The. Low-side current sensing in each leg of the current driver Comparing the 3-shunt low-side technique with the previous version allows a better approach of the phase current flowing into the motor even if it is not an exact equivalent. The low-side configuration allows the use of low power op-amp as the common mode is close to ground.  · \$\begingroup\$ The location of the current sense resistor determines what current you are sensing. Unless you have a compelling need to measure the current used by the gate driver, I recommend that you place the gate driver ground on the GND side of the current sense resistor, not the FET source side of the www.doorway.rus: 5.

Current-Sensing Low-Side MOSFET Driver current sensing – - MOSFETs. Low-side switches are designed to work from to +°C. ST's low-side switch and driver product portfolio includes single and dual drivers with digital status and on-resistance values ranging from 10 mΩ to mΩ. These versatile devices address many power applications in automotive body electronics, and are available in a wide variety of.

The low side switch operates by applying an input voltage to the gate and connecting the MOSFET Source to ground. This control scheme is the same as with. IR are low and high side drivers respectively, which have a high shows the circuit configuration if you are using a Hexsense current sensing MOSFET.
