Cnc projesi hazırlanmış bir motor kontrol devresi temel elemanlar L6203 ve L297
Half bridge motors driver up to 2 amper / stage and this allowed me to do a bit of experience in the piloting of stepper motors. I even built a whole cnc funzionante.Sapevo to have suitable bridges to drive cnc small size and now it is time to move on to something more powerful. the bridge that I present here. It employs two integrated L6203 that each pilot phase and a L297 which is responsible for the translation of step and implements the chopper.
L6203 Dmos Full Bridge Driver
- supply voltage up to 48v
- 5a max peak current (2a max. for l6201)

- rds (on) 0.3 Ω (typical value at 25 °c)
- cross conduction protection
- ttl compatible drive
- operating frequency up to 100 khz
- thermal shutdown
- internal logic supply
- high efficiency
L297 Stepper Motor Controllers

Bu devrenin şematiği yokmu ?
L6203 ün bağlantı şeması nasıl oluyor? 1. bacak en soldaki ilk bacak mı oluyor?
