Resolved! About the TS33 series
I don't know the internal structure of the TS3330AMR IC.Is there a functional block diagram of the IC's internal structure?
Resolved! STUSB4710A output not stable
I developed a multi-port charger with multiple STUSB4710A and companion ST1S14PHR with the recommended bill of materials. The evaluation kit worked fine however my board does not work consistently. I read back the status register and detecting underv...
l7987l Arcing across soft start pin
Hi,L7987L IC is used for generating -15V from 24V supply. it was working OK up to 12V, upon further increasing Supply Voltage we found arc at the soft start pin.
[L9369] Reg 6Fh D[1] =0 to set Low ohmic path to be connected or disconnected?
Register 6Fh, D[1] SPI_HSoff_highLow ohmic path switch off disable bit for HS pre-driver stage A and B0 / R/W (default) (‘1’ = low ohmic path enabled)When D[1] =0, Low ohmic path between HS driver GHy_x and SHy_x is connected or disconnected?When H-...
[L9369] Can SPI_set_PWM and SPI_PWM_A be set together with only one read-write operation?
Per example code of L9369, to set SPI_set_PWM, one read-write operation for 6Ah is used and to set SPI_PWM_A, another read-write operation for 6Ah is used. My question: Can two separate read-write operations be merged into only one？ Thanks!
[L9369] when to set RST function enable on EN_EL pin (#47)
EN_EL pin (#47) is originally EN function and to set it as RST function， need to set D[4] of reg8Ah. My question: When to set D[4] to 1 to enable RST function? should it do after setting watchdog ? Thanks! RST Remapping on EN_EL the function of I...
L6599 Protection
Hi.I am using the L6599AD without PFC.Previously, the DIS pin was connected to the DELAY pin and used as a SHUTDOWN.However, the frequent peak current caused SHUTDOWN.So I connected the DIS pin to GROUND and made it work in HICCUP MODE.However, the ...
STPM33 - Voltage and Current Readings Increasing Over Time
Hello,I have developed a custom board using the STPM33 to measure power consumption. The schematic is identical to the evaluation board.I can communicate with the STPM33 via SPI and have verified that the data I write is correctly stored in the devic...
Resolved! MC34063ACD-TR
Hello Anyone did ever you use the MC34063ACD-TR for to power on a "MCU" at 3.3V? From datasheet it seems it needs change R1 and R2 for to obtain the goal but the figure 15 shows until 5V so..I ask you if i can use it for my application. My applicatio...
STWLC99 cannot connect to GUI
我的WLC99RX开发板无法连接到GUI，我下载了wlc_ft260_Recovery这个文件，我连接了STEVALUSBI2C，但是并没有用，可不可以给我一个详细的教程。我还有一个问题是解释我的GUI界面似乎与开发板手册上的展示的不一样，GITHUB网页已经404，请问可以通过邮箱发给我与手册上展示一样的GUI软件吗，谢谢 Translation: My WLC99RX development board cannot connect to the GUI. I downloaded the ...
