mosfet gate drive impedance gearhead - 15:15 14-01-08 I have a situation where I need to use a pretty stiff pull-up resistor
on a mosfet gate because I'm going to use a comparator
to turn it off, and I plan to limit the current the ... Read More

mosfet driver question 14:35 12-01-07 I'm thinking of getting a TC1427 mosfet driver to power a motor by
parallel port. I'm about to place the order, then I thought of a few
questions:
Can I drive a 1A load direc... Read More

Mosfet Roger Dewhurst - 17:44 15-10-07 How are the pins of a mosfet identified please.
The project requires a 45V/16A Schottky diode or similar. I cannot find a
supplier. What is special about a Schottky diode? ... Read More

Mosfet as a 12V Switch (and opto) ProgrammerChicago@gmail.com - 12:46 07-10-07 I've been stuck on this for awhile. I've got a MOSFET that is not
behaving the way I expect.
I was hoping it would act similar to the following animation where

mosfet? transistor? hexfet? 14:46 21-12-06 When would one use a transistor? mosfet? hexfet?
Basically looking into PWM switching of medium-sized DC motors (12V,
~5A or so).
Which should I use...? A beefy transisto... Read More

MOSFETs and PWM Randy Day - 13:05 24-02-07 I've built some TTL motor/relay controllers
out of NPN transistors in a Darlington
configuration, and I'm considering using
mosfets instead.

nulling offset in a comparator gearhead - 16:46 29-12-07 I need a blocking diode that will
conduct about ten amps. I have a
leftover comparator out of a quad,
so I decided to use parts the circuit
already has and run the comparator
