Review on 💪 Enhanced Performance: HiLetgo BTS7960 Driver Arduino Current - A Perfect Choice for Efficient Motor Control by Omar Alradwan

This is a very affordable and economical solution for PWM control of large DC motors. I did a lot of research and found that Infineon's single bridge ICs are the best sport dual FETs and drivers in one IC package! They have newer IC models that support up to 70A peak and up to 50A continuous, but nobody has mass-produced a cheap module like this. If you search for the Infineon IC model BTS7960B (actually BTN7960), this IBT-2 motor driver will show up everywhere. I would like to see mass-produced BTN8982 ICs. Anyway, this IBT-2 motor controller also has a 74HC244 octal buffer that isolates the Arduino/PIC/Arm microcontroller from the Infineon IC. good protection. Each IC can either drive 1 motor in 1 direction (total 2 motors -> one direction) or you can combine them into an H-bridge and drive 1 motor in 2 directions (forward and reverse). I like configuration #2. If you use this in H-Bridge mode, you need to activate the enable pins on BOTH ICs. 1 IC drives your + side, the other drives -, so both ICs must be on to conduct. Send a 1kHz to 25kHz PWM signal to any IC to drive the motor in that direction. You need to develop logic to ensure you use PWM on one input at a time. Finally I ordered 2 of these controllers and one of them came with errors, very serious errors. Like it smokes and fizzes just plug it in and use it. Both microcircuits had obvious solder bridges between different sets of contacts. Those weren't ground contacts. A pair was Inhibit -> OUTPUT. The other jumper was OUTPUT -> Slew Rate. The chip was also crooked to the point where the connector (output) was a micron from the pin on the left chip. They almost touched. Had to rework something, which I like to do anyway :). Photos are attached. I added some solder to fill some of the heat transfer holes to the heatsink. Also add some fine ceramic heatsink paste. The solder pad on the left is OEM. Not much solder in the vias. However, there is a "too much" limit. You don't want the heat in the solder to just be transferred.
