We would like to inquire if there is a solenoid valve drive solution that can meet the following requirements:PWM frequency 0-5000Hz, current 0-3A , can superimpose dither signal 100-1000Hz, 0-600mA, dither waveform: sine wave and triangle wave
Hello! Hope your team is well and everything is fine!I'm currently using two stpm34 chips on a custom board connected in cascade to perform voltage and current measurements.Right now I'm performing measurements at a specific time through a timer inte...
Hi,I am using the STUSB4500QTR in my design.Pin 3 (in QFN package) is defined as NC.I saw that in some design examples it is connected to ground.Is it alright to connect it to GND or it should left disconnected?Regards.
Hi all, For the motor driver IC L6235Q the datasheet states it has overcurrent protection at 5.4A, can this value be changed to cut off the circuit at for example 3.0A? Thanks
Hi everybody,I made a circuit for the STPM34, but I keep destroying my components :)The first image is what my circuit looks like, I followed the datsheet closely, yet there seems to be a mistake somewhere.I've noticed it goes wrong at my current mea...
I am currently writing a driver for the STUSB4500L which has the ALERT pin (active low) connected to the MCU. An interrupt is triggered on a falling edge, and I then read the ALERT_STATUS_1 register. But somehow, the interrupt is not cleared. I then ...
1.I previously developed a product that, due to a program bug, continuously wrote to a fixed address in the EEPROM IC (M24C64-F) every 25ms while in standby mode. After about 1 to 2 years of the product being sold, we got feedback from those issue t...
Dear ST Team:We have E2PROM M24C64-WMN6P in our project, we checked from datasheet Page 20 & Page 25,there is a confusion need your help.ThanksOn Page 20, Table 12 shows Cbus load for I2C is 100pF max and 50ns max rise time,While on Page 25,Table 19 ...
Hi everybody, I'm new to this forum and have a problem involving an ST62T65CB6 microcontroller. I have been programming PIC chips for a long time and am familiar with the process of reading and writing to memory. My problem is that I have a board wit...
