sn754410 connection to a BS2

froslie

I'm planning to use a sn754410 to drive a motor from a BS2. I'm curious if anyone knows of good source to get an idea of connection and code?


thanks

The hook up is pretty straight forward (no extra components are needed):

Pin  Description
---  ----------------------
1    Regulated +5v
2    Input 1 for Motor A
3    Output to Motor A
4    Ground
5    Ground
6    Output to Motor A
7    Input 2 for Motor A
8    Votage Supply for Motors
9    Regulated +5v
10   Input 4 for Motor B
11   Output to Motor B
12   Ground
13   Ground
14   Output to Motor B
15   Input 3 for Motor B
16   Regulated +5v

I used the 754410 in a motor controller project. I have a write up on my home page:

system.windows.codeslinger.googlepages.com/motorcontroller2

A gif image of the schematic is on the right; one is the logic board and the other is the motor board; the 754410 is on the motor board. When you look at the schematic, you should keep in mind that I'm actually using the 754410 to drive MOSFETs that in turn drive the motors; I'm not driving the motors directly because I need about 10 or 20 amps.

I haven't had time to finish the code for the controller, unfortunately.

thank you. this is a very simple IC to connect as it turns out.
