I didn't found documentation about coding of the L9966 SPI interface.
L9966 has one spi interface to work with MCU's, but I need to know how it is working an d I didn't find documentation about it. Can somebody tell me where to find it?
GP244
Hi,This is a over voltage diode from a uC programmer that I blew. Can anyone tell me the value? Thank you for the help,Rob
L6235Q - Using DIR with PWM signal (DT0001)
I found an aplication (ST Design Tip - DT0001), that suggests a way of controlling motor speed, using a PWM signal on the DIR input. Works fine for speed. Note: we are not using a micro as shown in the DT90001. We are using our design. And using P...
EVALSTPM34 boards work unstable when using single Clock source
Hello, I am trying out a 220 V power measurement set up with 3 STPM34 evaluation boards. I need to use as less wires as possible, so I am using SPI with 3 different CS and 1 SYN pin. I am also trying to reduce component count by using only 1 CLK sour...
Resolved! L6902 component choice
Hi, I'm designing a DIY switching power supply around the L6902. Intended output voltage is <22V, input voltage 24V, output current in constant current mode between 0.6 and 0.8A.My questions:the datasheet shows an inductor value of 22uH, is this valu...
Getting started with the STDES-30KWVRECT 30 kW Vienna PFC rectifier reference design UM3011
I am working on Vienna PFC rectifier and was studying ST Microelectronics application note UM3011.In the note equn. (9) is given as while my working on these equations I got following results If someone can go through my derivations in attached file ...
Resolved! Using MPP on stwlc38
Is it possible to use a Qi2 rx coil with magnetic array on a stwlc38 design? The goal is to use a Qi2 charger and reap the benefits of magnetic alignment and 15W charging while still being on the Qi1.3 standard of the stwlc38.
ST Motor Control Workbench "PDSC version is not supported"
Hi, I am currently working on a project that uses a BLDC motor (42BL90L2-3), and I am trying to drive it using a DRV8323 gate driver. I have been using the ST MC workbench (version 5.4.8) to profile the motor and control unit, but when I try to gener...
Viper06LS shuts down over 520 VDC Input Voltage
Hello,I use the Viper06LS in the Buck Converter topology.The input voltage can vary between 100V and 530VDC. The output voltage is regulated to 10 V. (See "Viper_circuit"!)Unfortunately, a problem arises when the input voltage increases to approx. 52...
STC3115 SoC indicates 100% too soon while charging - Detailed Post
Hi all,We're using the STC3115 for a single-cell lithium battery, the main goal is to provide a SoC that gives the user a feeling about remaining battery life.This is working quite well when we're draining the battery completely, even in very differe...
