Requesting Spice Model for L9338
Hello I’m currently working on a design that uses the L9338 Quad Low-Side Driver and would like to perform circuit simulations in LT spice (or any compatible simulator). Could you please provide the SPICE model for the L9338?If it’s not available pub...
Resolved! STUSB4500 Variable Voltage
Hello, Is there a way to set up the Sink PDO to take in a variable voltage? I would like to set up PDO2 5-20V 3AmpsPDO3 5-20V 5Amps My plan is to use the Power Ok GPIOs to determine how much current I have and do some down stream current limiting. ...
SRK1000 usability test remarks
Last week, I have been testing SRK1000A in EVLSRK1000A-PF, in an application with 250 kHz fixed frequency flyback PWM with primary side control.1. I struggled around the gate no longer driven in CCM-mode, and even in DCM upon more than moderate load....
Resolved! VN9E30F: SPI Error & Fail Safe mode isnot getting clear.
Hello,I am trying to send first command from the MCU (s32k312 -NXP).I am able to send but I am getting SPI response likeAnd afterwards, no matter which SPI commands send, it always sends same response from the chip i.e. 0x610000As per the Datasheet, ...
L99LDLH32 modify Responder ID issue
Hi everyone,Good day!I'm currently working on modifying the Responder ID using CAN FD communication.I initially had a firmware running on an MCU that was capable of modifying the Responder ID. My goal now is to analyze the CAN FD communication from t...
Resolved! STW3N170 - DC SOA
Hi ST,I am using the STW3N170 in a linear application (constant current source) where the voltage can be 1500V and current as high as 16mA - total 24W.Can you please share the DC Curve of the SOA, please include in the graph the Thermal Instability d...
STP16CPC26 flash on power up
Hi! I'm using the STP16CPC26 as an LED driver, but have a problem where all the attached LEDs initially flash when powering up. This is a problem since this is a UI with a large-ish number of LEDs and you get hit right in the face with the bright fla...
L6981CDR stops working
We have approximately fifty modules in the field that use the L6981CDR. The schematic below shows how they are connected. The L6981CDR is used (in combination with other components) to generate an output voltage of 5V. This output voltage is used to ...
Resolved! LDL112PV33R not working. giving Vout same as Vin .
Hi ,Recenlty I designed the my custom board with LDL112PV33R . My Vin is from Battery charger BQ25620 which is 3.7V. Now LDO giving directly 3.7V at Vout. I done following diagostics. check marking on IC which ic ''L112 33''. which is indicating Fix ...
Resolved! STUSB4500 I2C hot swap
We're using this controller in our project and have the VCC pin tied to VBUS so the device does not pull power from the battery when USB is not connected (it was pulling ~125uA which is too much for our battery life as the main power is not turned of...
