ISO808 Fault status
During a short circuit of the ISO808 channel output (+28V) to ground, the fault status shows a voltage between 0.8V and 1.4V instead of 0V. When the short is removed, the fault status reads 3.3V. A 1k pull-up resistor is connected to the fault open-d...
Resolved! How to set the STWLC38 to 15W(EPP)
Hi,I use the STWLC38 for wireless charging.Just set the BPP VOUT to 9V, and other REG is in default value.In test , the output current around 0.6A . (The chip emits a squealing sound)If I want to set the Rx to 15W, which REG I need to set. And I have...
Resolved! STWBC86 Refrence 5W design
Hello,Could you please direct me to a complete reference design schematic? The one provided in the datasheet appears incomplete, and many of the forum links on this topic seem to be inactive.Your assistance would be greatly appreciated.
Resolved! STEVAL-WLC38RX Not connecting to STSW-WPSTUDIO
I get an error message when I try to connect with the STEVAL-WLC38RX evaluation board using STSW-WPSTUDIO. I am using v2.7.2 of WP Studio. See error message attached.
Resolved! STSW-WPSTUDIO GUI cannot recognize STEVAL-SWLC38RXA & STEVAL-SWBC86TXA
Hello, Recently, I purchased the STEVAL-SWLC38RXA and STEVAL-SWBC86TXA eval boards from Mouser. After some digging, I found the GUI and downloaded the STSW-WPSTUDIO v2.7.2. When I connect the RX board, I see the LED turn on. When I connect the SWBC86...
Resolved! STLQ020 reverse protection diode?
I'm working on a low-power design and planning to use a STLQ020. The datasheet doesn't mention the need for a protection diode, nor does it mention that there is one integrated..Is there an integrated protection diode?
L6474 Driver Stalling at 15kHz step frequency
Posted on August 05, 2014 at 00:06Hello, We're having issues with the L6474PD driver and stalling. I'm testing it with the L6474PD evaluation board powered by 24V. Logic is at 3.3V. Motor runs fine below 15kHz, but right around that frequency it s...
L6474PD
I am working on L6474PD motor Driver.I could figure out that, if the input is between 8-48v it would internally regulate the voltage and supply to the logic circuit of L6474PD , but my question is will the L6474PD independently drive the stepper m...
L78xx datasheet formatting
Through the Characteristics chapter of L78XX DS, the page break is placed incorrectly so, that the conditions - and sometimes also the first row of the table itself - is at the preceding page. Yes, it's formally OK, but is this how ST intends to pres...
How to get Equation2 in AN5287
Hi there,I am studying the application note: AN5287. It provides lots of helpful information about SMPS calculation.But I don't understand Equation2. What is original formular for this?RegardsAlex Chen
