描述 Description

The L6235Q is a DMOS fully integrated 3-phase motor driver with overcurrent protection. Realized in BCDmultipower 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 generates the required sequence for the power stage. Available in QFN48 7x7 package, the L6235Q features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
