STMicroelectronics L6235Q 3-Phase Brushless DC Motor DMOS Driver Datasheet
The L6235Q is a DMOS fully integrated 3-phase motor driver with overcurrent protection, realized in BCD multipower technology. It combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip to drive 3-phase BLDC motors. The device includes all necessary circuitry, such as a 3-phase DMOS bridge, a constant OFF time PWM current controller, and decoding logic for single-ended Hall sensors.
Available in a QFN48 7x7 package, the L6235Q features non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown. Key specifications include an operating supply voltage from 8 to 52 V, a 5.6 A output peak current, and an RDS(on) of 0.3 Ω typical value at 25 °C.
