New products: G2 High-Power Motor Driver 18v25 and 24v21 (and price drops for other G2 drivers)
- 31 July 2017Hi.
We do not commit to the exact MOSFETs on these, but the Rds(on) is around 1 mohm for the 18v25 and 2.4 mohms for the 24v21. Keep in mind that there are 3 MOSFETs in the current path because of the reverse protection MOSFET.

Pocket-sized USB charger adapter
- 18 July 2017Hi, Manlio.
Adding capacitors might help. You might find this application note about dealing with motor noise helpful.

New product: 12V, 2.2A Step-Down Voltage Regulator D24V22F12
- 3 July 2017Hi, Aaron.
We do not release the name of the chip used on those regulators. The power good pin is an indicator of whether the output of the regulator is above 85% or 90% (depending on if the output voltage is falling or rising) of the intended output voltage. The power good pin is pulled low when the regulator is not enabled. It seems like you are looking for a feature that tells you if the input power is good, in which case this regulator is not appropriate.

New Product: 5V, 5A Step-Down Voltage Regulator D24V50F5
- 5 June 2017Hi.
This is one of the ones where we do not disclose the schematic.

New high-current stepper driver carrier with SPI: AMIS-30543
- 8 May 2017Hi, Mathieu.
It looks like you asked the same question on our forum. Please see our response and if you need more assistance continue the discussion there.

New Product: 5V, 5A Step-Down Voltage Regulator D24V50F5
- 1 February 2017Hi, David.
Details for how the enable pin functions and its threshold can be found in the "Connections" section of the D24V50F5 regulator's product page.

New D24V150Fx 15A step-down voltage regulator family — our highest-power regulators yet!
- 16 November 2016Hello.
We do not have the available output current vs. ambient temperature characterized (the available current depends on several factors). In general, the regulator is limited by heat dissipation, and the higher your ambient temperature, the less current will be available. The maximum continuous current graph on the product page is for the hottest part of the board getting to 125°C; the thermal shutdown is around 160°C, inside the regulator IC.

New D24V150Fx 15A step-down voltage regulator family — our highest-power regulators yet!
- 4 November 2016Hi.
We do not have that characterized, and I do not have a setup to test it well, but I put a 6 V unit on my scope with 24 V in, and I'm seeing around 35 mV peak to peak across a wide range of loads.

New MOSFET-based power switches
- 16 September 2016Hi, Thomas.
There is no microcontroller in our pushbutton power switch circuits, so they cannot be reflashed, but if your system has a microcontroller in it, you might be able to add an external pushbutton to the A pin on the board and get the behavior you want. A similar application where the user wanted to push a button when their system was off to turn it on, and then detect any additional button pushes with a microcontroller and initiate a power down sequence was discussed in this thread on our forum. You might be able to use the same circuit and program your microcontroller to monitor the button for a few seconds to decide when to turn off.

New Product: 5V, 5A Step-Down Voltage Regulator D24V50F5
- 20 July 2016Hi, Paul.
The regulator does not have a microcontroller on it. It uses an IC designed specifically for controlling the circuitry of a buck regulator.
