How to Safely Diagnose and Recover STEVAL-L99615C Board Suspected FUSE Activation
Hello,We are using the STEVAL-L99615C board and encountered an issue while testing the Demo1, Demo2, and Demo3 examples. After running the demos, the board became unresponsive. We suspect the issue might be related to the FUSE mechanism described in ...
L9961 charging (CHG) & discharging (DCHG) FETs during fault conditions
I am working with the L9961 IC for battery management, and I have a question regarding how the charging (CHG) and discharging (DCHG) FETs are turned on or off when faults occur.From the datasheet, I understand that:The FAULTN pin is used to signal fa...
Query on Using STM6601 for EN deassertion
Please confirm, for enable deassertion by long press, PB need to be pressed or both PB and SR needs to be pressed. The datasheets mention two things, Note: I need to achieve EN deassertion by long press with one button and INT pin is not connected to...
Query on Using STM6601 for Single Button Power Control
I am planning to use the STM6601 in my design, which involves powering on with a single press and powering off with a long press. However, my device only has one button. I want to implement a long press to turn off the device, but based on the diagra...
Unknown Command "DC 0C" while programming STPMIC1A
While programming the STPMIC1A with the USBSTICK – I2C to USB interface, I logged the I2C communication with an oscilloscope. This showed a command "Write, 66, DC 0C" that was send to the STPMIC just before the command to write the shadow registers t...
Resolved! led2001 Resistive load
I am willing to drive a 0.1OHM resistive lead with 4A.Can It be done? eDesignSuite notes that it is possible.I am getting only ~1.4 Amps in my setup
SPV1050 Mode Issue
I am designing a PV cell charging circuit with SPV1050.When the configuration is set to boost mode, I am curious what happens if a voltage higher than Veoc is applied to the PV cell.
Driver for L9966 FlexInput IC
Hi, Is there driver available for L9966 FlexInput IC ?. Any pointers or code would be helpful.
Resolved! STDRIVE 101 ENx Pin
Dear ST community I would like to use STDRIVE 101 similar to STEVAL-POOL4A board (s. schematic above). But to reduce number of PWM pins used I'd like to pull all the ENx pins to VDD (e.g. +3.3V) and drive only INx's pins by an advanced timer. Accord...
L6986 - Output voltage problem
Hello,I have a problem with the output voltage of 3.3VWith input power up to 6V everything is fine. But when I increase the voltage up to 24V, the output voltage slowly changes from 3,3V to 2,8V. The load is about 50mAI can't figure out what the prob...
