Hi, Could I drive any motors directly using HCS12 output port pin with out any Drivers(H-bridge). If yes then could you please give the partno of that motor preferably with rotary encoders. Thanks Naheed |

PWM ports on HCS12

No! Well, maybe an extremely small one. But inductive kicks from the motor would blow the HCS12. H-bridge drivers are now available in very small packages. Check Infineon's TLE4207, for instance (8.75x6mm). And there are millions of motors you could drive with this. See Maxon, Portescap, Faulhaber (micromo.com), etc....

Naheed, The MC9S12H256 and H128 parts are equipped with outputs that can serve as H-bridges. These special H-bridges outputs (Ports U, V and W) have the ability to sink and source an increased current of 20mA (as compared with 10mA on other outputs), in order to allow them to directly drive H-Bridges. Hope this helps, Doron Nohau Corporation HC12 In-Circuit Emulators www.nohau.com/emul12pc.html At 06:53 PM 8/4/2003 +0000, you wrote: >Hi, >Could I drive any motors directly using HCS12 output port pin with >out any Drivers(H-bridge). >If yes then could you please give the partno of that motor preferably >with rotary encoders. > >Thanks >Naheed |
