Resolved! Looking for a low Iq (e.g. 1uA) eFuse
Hello,I looked through the data sheets of multiple efuses and cannot really find reliable values of Iq (quiescent current) values (somtimes only leakage for certain pins is given). Even the product selector does not show any listings of Iq. Every oth...
Resolved! Looking for Gerber Files or Development board for 3KW inverter application note STEVAL-ISV002V1
Hello Team I am looking at how i can buy the reference for evaluation board STEVAL-ISV002V1 or the and the gerber files if possible. any assistance would be appreciated. regards joshua
Grid tie based solar inverter reference designs
I am in the process of designing a new grid tie based solar inverter.i am designing it for a load of 1650w approx.Please share some technical documents and reference designs to start my design mainly from STMicroelectronics.
Resolved! STDRIVE101 PWM Output Jitter Inquiry
Hello Team,I am planning to use the STDRIVE101 to develop an ESC, and I would like to clarify something before proceeding.Does the STDRIVE101 introduce any jitter in the PWM output? If so, what is the typical jitter value?Thank you for your help.Best...
Clearance problems in the Gerber Files “en.stdes-2kw5ch48v-gerber”
Hi there,I downloaded the gerber file “STDES-2KW5CH48V GERBER ” and found that there is obvious wrong with copper pouring clearance. For example the clearance between main lines and ground is less than 15 mil.
Resolved! STGAP3SXS datasheet need correction
InSTGAP3SXSdatasheet is funny table , input -> output state, the most important thing for a driver - but wrong:btw : 1. Do not care. -- is perfect here.
Resolved! Unconventional use of L9826 (erroneously before L9925)
In my project I use a L9826, 6 Outputs are used conventionally 2 outputs are not used. In the same project I need to have 2 digital inputs (SPI) and I would like to know if I could use the two unused outputs of the L9826 as HCMOS inputs via the Fault...
Resolved! VIPER26K device fails when we tried to measure VDD pin voltage with respect to power ground
We designed a buck converter with (300-800) input DC voltage and the output voltage is 24V. The max load current is 150mA. We noticed two issues here:1. The device fails when we try to measure VDD pin voltage with reference to Power Ground (DC inpu...
Is it possible to use L9963E daisy chain without L9963T?
I'm using a single L9963E and it works fine. However, I couldn't start daisy chain connection. When I consider BMS architectures in datasheet, all of them has L9963T transceiver to communicate with further IC. My custom PCB doesn't provide L9963T.So...
L6227Q / L6226Q use with PWM at control inputs
Hi everyone,we're currently using the L6227Q as a driver for 2 DC motors. Everything seemed to work fine. We put on 3,3V on the VREF_x inputs. Enable the IC with EN_x to high and apply a PWM (100 kHz) at the IN1_x and IN2_x. With the PWM (depending o...
