?? ? 说： when I use DRV110 drive the Electromagnetic brake, I found if my pwer supply is 48V, then the VIN is going to be 15V, because of the function of 15V zener diode inside, but the OUT pin PWM frequency became unstable, and the Electromagnetic brake…
The LED current can be set, and controlled dynamically, by using the IADJ pin of the TPS92512. Below equation shows how to calculate the value of the current setting resistor (RISENSE) from the ISENSE pin to ground for the desired LED current.
The IADJ…
Thank you for your response. I'd like to ask:
What different behaviors would the Charger IC exhibit when the CELL_BATPRESZ pin is pulled low versus not pulled low in the absence of a battery?
What is the correct connection method for the CELL_BATPRESZ…
Part Number: DRV110
Hello, according to the specification of the chip, under the condition that the PEAK and HOLD pins are directly connected to GND and RSENSE = 1 ohm, the lower limit of the current deviation is 20%, the upper limit is 30%, and the excitation…
Hello ，
You may keep R1=20ohm to slow down turning off speed of Q3. Try adding FB or small resistor between VOUT and LED ANODE. Adding small cap on LED anode to GND.
Do you mean LM3409 got damaged if changing C8 to 22uF cap? What do you mean an inductor…
