Are there resources for learning to write drivers?

I have a decent amount of experience designing hardware and embedded systems in general, but I have never written a driver for an operating system. I would like to know if there are any good guides, preferably online, although good books would…

Help wanted with vacuum fluorescent display (VFD)

In a box with old components I found a 16 character, 19-segment Futaba VFD: I would like to use it for "something" but I haven't the foggiest how to drive such a display. Even the filament is an unknown factor to me. The device dates at least from…

How does a Line Driver actually works?

So I've searched for days for information about the 74HC244 line driver. As always, the Datasheet provides raw and not very good information about the actual component :) (I mean, it gives us the temperatures, but not how the actual component…

Is mVtt the same as mVpp?

I am designing a driver circuit for S/PDIF, and in a couple different places, like this one, it specifies an amplitude of 500 mVtt. I'm not familiar with those units, and googling gives me nothing. However, I do see it specified as 500 mVpp in a…

What is the difference between L293D and L293NE?

I tried to find a L293D motor driver but I was able to find only the L293NE. What is the difference (even google could not tell me)?

Looking for a quad low side power driver IC

We have been using the Allegro UDQ2559LB. This is a quad (4 channel) low side power driver (used to drive relay and lamp loads) with about 0.5 amp per channel capability and overload, short circuit, and over temperature protection. Allegro is…

LED driver internal circuitry understanding

Whenever we talk about LED driver we always think of driving a transistor by keeping a LED in at its collector along with a series resistor. But I wish to understand what actually these LED driver ICs do? What all the internal circuitry does? From…

Question regarding LM5113 Driver

I have a few doubts regarding the driver LM5113 (and IC's in general at this point). As can be seen in the schematic below, VDD is provided with 5.1V via the Zener Diode. I was told (with no further information) that, the chosen resistor (R50 = 787…

What's a single-ended single duplex buffer with 5V drive strength?

I'm interfacing to the "Dynamixel TTL" bus, which is a simple TTL serial bus with multiple talkers. Thus, while I'm not talking, I need to tri-state the output, and be prepared to read input. There is a single coordinating master, so collision…

Stepper driver reverse polarity

I would like to use a MKS TB6600 4.5A drivers together with an E-cut break out board to drive Nema 23 stepper motors (3A). My problem is that I cannot figure out how to connect the drivers to the board. Before I fry both the BOB and the driver I…

No HO pulse on IR2184 in half h-bridge

I am unable to get any output on HO pin of IR2184 high side gate driver when I tried to drive a half H bridge. Vcc is around 12-15V, input to IC is around 8V square wave, bootstrap capacitor voltage is observed to be around 8V. I m able to get LO…

MIC5891 driver output voltage

I am troubleshooting a relay driving board that uses an MIC5891 to drive a 12VDC relay (86Ω coil). The load supply voltage into the 5891 is 12V. When checking an output with no load I get 12V. When I put even a small load on the output (115ma…

L298N Current or Voltage source

I want to power some coils using a controlled current, but I know as the coils heat the resistance changes. Will the L298N keep that current controlled at a certain enabler voltage?

With this MOSFET driver IC, is the output voltage range 0 to Vin or 0 to Vcc?

I am using this driver IC, ZXGD3005E6TA. I am using a Pi as my controller, which has an output of 3.3V. The Vcc of my system is 12V. I cannot determine if the IC will output the 12V when I supply 3.3V at the Vin pin or if it will only match the Vin…
