MOSFET product selection

Hi Art,

Thanks for the inquiry. Those are relatively low currents and TI has multiple devices that can handle them. Can you please provide more detail including the type of application, input voltage range and gate drive voltage. That will help narrow down the FET selection. We have multiple resources on the MOSFET Support & training page including guidance on FET selection and tools to calculate FET power loss for various applications including load switch, sync buck converter, non-sync boost converter and BLDC motor drive.

Thanks,

John Wallace

TI FET Applications

Hi John,

Good day.

According to the customer, application is for Measurement of Voltage drop using different currents.
MOSFETS.
input current. -----> 1. 1 mA-1 A and 2. 1 µA-1 mA.
Input Voltage --------> 1. 1 µV- 1 mV, 2. 1 mV - 5V, 3. 1000 V
Thanks,

Art

Hi Art,

Thanks for providing the additional information. TI FETs are rated up to a maximum 100V. We have no devices to support 1000V requirement. Also, these are power MOSFETs and can support currents much greater than what your customer is looking for. I am not fully understanding the application and don't think I can make a good recommendation. Can you provide a circuit diagram showing how the FET is being used in the application? Is the customer measuring the voltage drop across the FET or some other element such as a sensor or transducer? How are they driving the gate of the FET? Is this ground referenced: low side switch with source grounded or floating: high side switch with source not grounded?

Best Regards,

John

Hello John,

I just sent you a separate email regarding this.

Thanks and regards,
