Other Parts Discussed in Thread: SN74LVC1G17, , ISOW7721
Hello,
I would like to pass a PWM signal from an mcu that runs on 5v on one side to the other side that controls a driver (motor/led) ic pin (also 0v-5v-max via pwm signal). main issue is isolation between both sides.
Attached is the schematic as a suggestion option that uses 4n25 Phototransistor with SN74LVC1G17 buffer as i am not sure they fit together? (The question reffers to the Phototransistor left side circled in order to complete the isolation).
After looking on TI's ISOW1432 (that uses the same idea for other application) Can you please advice if TI has an 1 channel opto ic or any other solution ic to combine with the SN74LVC1G17 in order to pass this pwm signal smoothly?
Thank you in advance,
