You can see an opamp configured with this pinout. In case this pinout is intended to be not used, it must be terminated to the +5 V supply rail. Pin#12 = (EN) A LOW logic signal will shut OFF all the internal power MOSFETs and stall the BLDC motor. For enabling a fixed clockwise or anticlockwise directions, this pinout may be appropriately terminated to a +5V or the ground line. A HIGH logic level on this pinout will cause a forward motion while, a LOW logic level will allow the BLDc motor to rotate in the opposite reverse direction. Pin#11 = (FWD/REV) This pinout can be used for changing the rotational direction of the BLDC motor. Here the inverting input of the sense comparator also needs to be connected. Pin#10 = (SENSEB) This pin must be connected together with pin SENSEA to power ground through a sensing power resistor. Pin#9 = (RCPULSE) Is configured like a parallel RC network attached between this pin and the ground, which fixes the period of the monostable pulse responsible for the frequency-to-voltage converter. here each single pulse from pin H1 is dimensioned in the form of a fixed and adjustable length pulse. Pin#8 = (TACHO) It's designated as the open drain output Frequency-to-voltage open drain output. Pin#6, 7, 18, 19 = (GND) These are the Ground terminals of the IC. The pinout function for the specified circuit can be studied from the following data: You just have to hook up the shown elements in place and use the design to operate any BLDC motor with sensors rated within 8V to 50V at 3 amps rate.

With regard to the built-in protections the L6235 device offers a non-dissipative over current protection on the high-side power MOSFETs, protection against ESD, and an automatic thermal shutdown in case the device heats up above the rated value. The chips integrates all the circuitry required for effectively driving a 3-phase BLDC motor, as explained below:Ī 3-phase DMOS bridge, a constant off-time PWM current controller and the decoding logic for single ended hall sensors for generating the essential 120 degree phase shift sequence for the power stage. Designed with BCD technology, the device embeds the benefits of isolated DMOS power transistors with CMOS, and with bipolar circuits within the same device. The IC L6235 is an embedded DMOS 3-phase motor driver with an integrated over-current protection.
