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...
Resolved! TS339I
Hi, Team We are facing issues with test process performed at ICT test station. We are testing driving current to detect Zener Clamp diode 8.2V, the units fail with 2.64688 volts, but this line is connected to comparator TS339I pin 5 that is not pow...
Resolved! VN5T016AH-E
Hi all.I would like to use the VN5T016AH-E high-side driver and I have some questions.*Are there 8V in the CS pin under fault conditions?*Can it measure max 4.2A with a K about 4240? Why do you specify 4V in the datasheet without knowing the value of...
How to set the output of high-side driver(VND7020AJ) with pwm
Hey,so I was trying to use the VND7020AJ as a driver to loads,and wanted to power the load to 7.2V while powering the high side driver with 12V.Im using a stm32f103rb,and using an outpin pin timer to control the pulse width to the input pin on the dr...
L9369 dual channels for one motor
The L9369 is dual channel solution for two rear wheels brakes actuators, but we need only 1 channel for one motor. Is there special design to combine two channels to drive one motor? If there is single channel EPB driver chip similar to L9369, L9369...
