L6235QTR

L6235QTR is a DMOS driver for a 3-phase brushless DC motor. It is a DMOS fully integrated 3-phase motor driver with overcurrent protection. Realized in BCD multipower technology, 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 generate the required sequence for the power stage. It features a nondissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
