How to use Low voltage Ballast ICs for UV- C Disinfection Lamps?
Hi @Swiftconnect, The ICB2FL03G's turn-on threshold is 14.0 volts, still, the input voltage needed for your application is 12 volts. Therefore, ICB2FL03G will not be the best option for your application. We do not presently have any other dedicated controller for UV-C disinfection lamps except for tRead more

Hello Erica Mills
First, let me thank you for posting.
1- To achieve a cycle-by-cycle protection function, you would need to apply your own logic using the HRTIM’s capture compare features and interrupts.
You could set up a capture compare unit to sample a specific signal or condition on each cycle and also use an interrupt to perform the necessary actions or trigger a fault if the condition exceeds a certain threshold.
This approach would require careful configuration and software implementation to achieve the required functionality.
2- Regarding the HRTIM initialization in CubeMX, the default configuration may indeed enable blanking.
Blanking is a point that prevents certain events (similar to fault events) from occurring immediately after a compare match. It provides a delay to avoid false triggering caused by transient effects.
While blanking can be useful in some applications, it might not be necessary or appropriate for all cases.
However,
If you believe that blanking is causing misunderstanding or unwanted behavior in your application.
you can modify the HRTIM configuration in CubeMX to disable or adjust the blanking settings according to your conditions. By customizing the initialization code, you can ensure that the HRTIM operates as desired in your specific use case.

Hello,
Thanks for reaching out to Volt Tech Community.
The acceptance filter of CAN is implemented with 8 acceptance masks (one mask for every four mailboxes). Masks are independently enabled or disabled for each mailbox. This cannot be done with FSP APIs. You can either manually write the Mask Registers (MKRk) (k = 0 to 7) or more easily set the group masks on the FSP configurator:
The above settings will set the MKR registers automatically:

See lessHow to Get High Speed LED Driver in Different Series?
Hello, Right, existing LED drivers all have PWM engines. It depends on the LED, some have Vf = 1.8, and some have 3.5V. So, 15x3.5 = 52.5 V in direct mode. Also current, 20 mA or more? For low current low voltage OPA may be an option, or OPA buffered by transistor for high CV. Thank You

How to get output in PDO2 with 3 PDOs work together?
Hello I assume that you're using our STEVAL_ISC005V1 board and what you call 'PDO1' is Vsnk from the schematic. However, Vsnk lights are on for all PDOs selections. Whereas PDO2 is ON if PDO2 is selected and PDO3 if PDO3 is selected. Our algorithm always tries to select the highest voltage. If the cRead more
Hello
I assume that you’re using our STEVAL_ISC005V1 board and what you call ‘PDO1’ is Vsnk from the schematic.
However, Vsnk lights are on for all PDOs selections. Whereas PDO2 is ON if PDO2 is selected and PDO3 if PDO3 is selected.
Our algorithm always tries to select the highest voltage. If the charger is so that PDO3 can be selected, then PDO3 Vsink will light on,
However, also PDO2 Vsnk will light ON. If the charger is smaller.

Hello,
Yes, the ESP32-C3 microcontroller provides access to the low-level RF encoder/decoder functionality for custom transmission and reception on the 2.4 GHz frequency. The ESP32-C3 is equipped with a Wi-Fi/Bluetooth subsystem, but it also supports other communication modes, such as RF communication using the RF module.
To use the RF module for your application, you would typically need to bypass the higher-level protocols like Wi-Fi and Bluetooth and directly control the RF interface. The ESP32-C3 provides a general-purpose radio (RF) peripheral that can be used for this purpose.
