If the parts aren’t popular enough, they are simply abandon or the remaining dies/mask sold off to some other companies that deals with obsoleted parts. Each process steps have their design rules/limitations and optimized layouts. Some of these are now built on newer often smaller geometries and often require resigning effort due to change in libraries specific to the process. There are cases where the same parts can no longer be manufactured as the process/chip fabs are obsoleted. God help you if your products relies on that and the engineers retired. There are applications where older transistors were far superior because they can dissipate heat better than newer devices with smaller dies. changes its specs, they should no longer same part number or they can no longer be tracked in the inventory. Part numbers are meant to *follow* their published specs, so products can be built over the year buying the same parts. May be you are the type tat don’t read datasheets or just have no idea. Posted in Robots Hacks Tagged h-bridge, L298N, motor controller, robot, tb6612, tb6612fng Post navigation Of course, you can always use relays if you want real old school. If you want more basics on the h-bridge, we’ve covered it many times.

If you know how to use the L298N, you can probably just snag a break out board, download the library, and be off to the races - no pun intended.

Of course, the TB6612 drops much less voltage which is great if you are using low voltage motor.Īssuming the new device is suitable for your hardware, the software isn’t really very different from L298N programs. The TB6612 boasts up to 95% efficiency and also has a low current standby mode.

However, because of its relatively low efficiency, it needs a heat sink. For example, the L298N can operate motors from 4.5 to 46V while the TB6612 can go from 2.5 to 13.5V on the motor voltage. looks at several ready-to-go breakout boards. You can get breakout boards for the tiny chips. The TB6612 may be a little more expensive, but it’s clearly worth it. In the video below, he uses a TB6612FNG instead, taking advantage of the device’s use of MOSFETs. has used L298N chips like this many times. If you want to build a small robot with a motor, you are likely to reach for an L298N to interface your microcontroller to the motor, probably in an H-bridge configuration.
