How can I turn off a PWM signal and turn on a High (one) in the same pin?

I´m using a PWM signal and the complementary with TIM1(timer1). The Pwm´s complementary singal is going out from pin A7 then I want to turn off the pwm signal from that pin and turn on a HIGH value (one) in the exact same pin (A7). The thing is that ...

We are using STPM32 metering IC for our application. We want to know the maximum current sourcing capacity of digital I/O pins, which is not clearly specified in the datasheet.

STEVAL-TSP004V2 configuration changes for 24V output

I recently obtained the STEVAL-TSP004V2 eval board, and tested it with Tripp-Lite NPOE-30W-1G injector. As supplied the eval board worked fine.I then modified the eval board as I require a 24V output, so :removed T5 and fitted a Coilcraft POE300F-24L...

Why VNH7040AY shuts off above 15 A immediately

Tested the VNH7040AYMounted on the official breakout board. (Also tried with custom PCB)Proper heatsink.50 and 100% 20 kHz PWM.With dummy load and also with real motor.Tried 7, 12, 20 and 24 Volt Vcc.Tried 3.3, 5 and 7 Volt control signal (INA, INB, ...

Why is the voltage high?

I’ve bought 1000+ L7805CP voltage regulators. On all the data sheets it say there is a +-10% voltage tolerance yet the voltage I’m getting is +55%. It says it’s input voltage range is 35v - 7v and its output is a nominal 5v (4.5-5.5v) yet I’m getting...

Problem calculating snubber component values for triac drive yields negative resistor?

I've tried to make a 24VAC triac switch driven by a triac optocoupler. It doesn't seem to be turning on fully. Direct connection of load to 24VAC measures .24amps but through the triac when on is only .13amps.I've gone back to the drawing board using...

In IC ST1S41, If EN pin is off what exactly will happen to the IC ? I mean, If EN is below 0.4V Does only switching stops or every operation of the IC stops

Is it dangerous to short circuit D1 on STM32F407 Discovery

Hi,i damaged D1 on my STM32F4 Discovery board. Afterwards, i removed D1 and shorted there. Now, it works. Can i use it or is it dangerous?

Help me to understand AN4998 reference design for IPS161H single high side driver

Can someone tell me the purpose of the elements highlighted in the attached scheme? I can assume that capacitor C1 is a DC blocking capacitor, but why is it so big value? The purpose of R16 and C10 I can not understand

looking for the MCU which have 16 PWM channel . please suggest

Required PWM - 16 Channel for the motor controller application .please suggest the best MCU with support RTOS.
