{1193A} Brushless fan motor driver circuit explained

In this video number {1193A} Brushless fan motor driver circuit explained. I explained the working of brushless fan motor using EC277 or AH277A based dual coil brushless fan mootor driver ic. it senses the magnetic flux in coil poles and shifts widing current direction. AH277A is an integrated Hall sensor with outputdriver designed for electronic commutation of brushless DC motor applications. The device includes an on-chip Hall sensor for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger toprovide switching hysteresis for noise rejection, a temperature compensation circuit to compensate the tem-perature drift of Hall sensitivity and twocomplementary open-collector drivers for sinkinglarge load current. It also includes an internal band-gapregulator which is used to provide bias voltage forinternal circuits. Placing the device in a variable magnetic field, if themagnetic flux density is larger than threshold BOP, thepin DO will be turned low (on) and pin DOB will beturned high (off). This output state is held until themagnetic flux density reverses and falls below BRP,then causes DO to be turned high (off) and DOBturned low (on) it is used in Dual-Coil Brushless, DC Motor·Dual-Coil Brushless DC Fan Revolution Counting Speed Measurement You are Invited to Join Haseeb Electronics    / @haseebelectronics   Please check other videos SMPS no output    • {966} SMPS Is not working, not turning on,...   SMPS step by step repair tutorial    • {528} How To Repair SMPS || SMPS Repair St...   How to download circuit diagram, service manual    • {558} How To Download Circuit Diagram, Sch...   Transistor, IGBT, MOSFET equivalent    • {233} How to find Equivalent or Substitute...   Broken plastic gear repair    • {679} How To Repair Broken Plastic Gear, D...   You can Follow me on :- Instagram:   / haseebelect   Facebook: https://web.facebook.com/profile.php?... #electronicscreators #tutorial #electronics
