The project consists of an \u003cstrong\u003eL6235\u003c\/strong\u003e device which is \u003cstrong\u003eDMOS\u003c\/strong\u003e fully integrated 3-phase motor driver with overcurrent protection. Manufactured in \u003cstrong\u003eBCD technology\u003c\/strong\u003e, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a 3-phase BLDC motor including a 3-phase DMOS bridge, a constant off-time PWM current controller, and the decoding logic for single-ended hall sensors that generates the required sequence for the power stage. Running the project in stand-alone mode, instead, three control pins enable the device, setting the direction of the rotation, breaking the motor, and the jumper chooses to run in torque or speed mode. The board is suitable for small motors used in many home appliances and can handle torque and speed control with a high efficiency of up to \u003cstrong\u003e95%\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eOperation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN4: Pin2 High\/Low to select the Direction of the Motor\u003c\/li\u003e\n\u003cli\u003eCN4: Pin 3 Enable, High=Enable, Low = Disable\u003c\/li\u003e\n\u003cli\u003eCN4: Pin 4 Brake, High=Normal Operation, Low=Brake\u003c\/li\u003e\n\u003cli\u003eJ1: Jumper Speed Mode or Torque Mode Selection\u003c\/li\u003e\n\u003cli\u003ePR1: Adjust the Speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOperating supply voltage from 8 to 48 V\u003c\/li\u003e\n\u003cli\u003eLoad Current Up to 2.8A, Peak Current 5.6Amp\u003c\/li\u003e\n\u003cli\u003eNon-dissipative overcurrent detection and protection\u003c\/li\u003e\n\u003cli\u003eDiagnostic output\u003c\/li\u003e\n\u003cli\u003eConstant t\u003csub\u003eOFF\u003c\/sub\u003e PWM current controller\u003c\/li\u003e\n\u003cli\u003eSlow decay synchr. rectification\u003c\/li\u003e\n\u003cli\u003e60° and 120° hall effect decoding logic\u003c\/li\u003e\n\u003cli\u003eBrake function\u003c\/li\u003e\n\u003cli\u003eCross conduction protection\u003c\/li\u003e\n\u003cli\u003eThermal shutdown\u003c\/li\u003e\n\u003cli\u003eUndervoltage lockout\u003c\/li\u003e\n\u003cli\u003eIntegrated fast freewheeling diodes (Chip)\u003c\/li\u003e\n\u003cli\u003e4 x 3mm Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 59.69 x 49.53mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCurrent Ratings\u003c\/h3\u003e\n\u003cp\u003eLoad current rated for a maximum of \u003cstrong\u003e2.8A\u003csub\u003eRMS\u003c\/sub\u003e\u003c\/strong\u003e. and \u003cstrong\u003e5.6A\u003csub\u003epeak\u003c\/sub\u003e\u003c\/strong\u003e.
