Nice one. Looks, (and sounds), great.
awesome video. i love the test jig.
Great vid, thanks Dan! 👍😀
When I started using these, nobody else was or at least posting about it. There were more expensive then but still less than the internet's fave. I have been using them in repurposed RC and toys. The current project is using the 16 channel LED/servo chip to handle multi-motor construction toys. Working to expand some code to use with two wheel or track steering/drive incorporating the servo chip. "RC Tractor Guy" wrote the base code that is being hacked on.
Fun fact: most of the cheap Chinese RC toys have H-bridge chips that match the pinouts of the TI chip. Some match the specs exactly. There is a strange two H-bridge chip that the pinout make it feel like there are two chips in one package. Separate Vcc, gnd, and unspecified outputs that wasn't connected.
Really really helpful!! Thanks for your hard work . I’m just learning to use arduinos and this is so useful
You are exactly the target audience and comments like this make my day! Thanks!
Im sure the most common use is rc vehicle for individual wheel control.
What happens if input 1 and input 2 is high at the same time?
It stops - same as both LOW - I think it's explained on the web article
@@SimpleElectronics Thanks for the demo. Unfamiliar with this one, but would like to see it go up to 12V.
Some bridge drivers have more states, like Break (open circuit) and Coast (short circuit), giving function to (0,0), and (1,1).
What happens if you disconnect one of the output wires while the motor is running?
If the chip burns, you would need external schottky diodes to VCC and GND on every output pin.
Synchronous rectification won't be good enough in that scenario.
