New products: G2 High-Power Motor Driver 18v25 and 24v21 (and price drops for other G2 drivers)
- 19 August 2019Hello.
Real regenerative braking, where you get a meaningful amount of energy out of a motor that is slowing down, is very difficult and generally not practical. The G2 high power motor drivers are not good candidates for doing this because you do not have sufficient independent control of the different MOSFETs in the H-bridge.
The older (G1) 36v20 CS motor driver does allow variable (PWM) braking, which is part of what you would use to implement regenerative braking, so in that sense it is the best candidate out of our products. We do not know of a good resource to recommend for how to actually implement regenerative braking.

New D24V150Fx 15A step-down voltage regulator family — our highest-power regulators yet!
- 29 July 2019Hello,
The DC current through the ground connection is relatively low; however, if you do not connect both grounds, it negatively affects the AC aspect of the regulator switching and increases both electrical noise at the load and radiated emissions throughout the circuit, so we do not recommend having a single ground connection.

New adjustable voltage regulators with multi-turn fine adjustment
- 19 June 2019Hello, Jose.
We do not disclose the regulator chip on those boards, but the soft start time is typically 850μs while boosting and 400μs while bucking. For information about other specific parameters please email us.

New 5V step-up/step-down voltage regulator S9V11F5
- 6 March 2019Hello.
Depending upon your Arduino it may be possible to use the raw supply along with the USB supply. If you are using an Arduino Uno or an Arduino Mega, the recommended input voltage is 7-12V, so I recommend using our S10V3F9 9V step-up/step-down regulator instead. However, because of the way the power circuit is designed on some Arduinos there can be issues with connecting USB and VIN at the same time. You could potentially power it using 5V on the 5V pin but that would bypass the regulator and would likely damage your board if you connected it via USB while it was powered.
Yes, adding a heat sink should increase the efficiency of that board, although we have not characterized how much it helps.
