STMicroelectronics L6229Q DMOS Driver Datasheet
The L6229Q is a fully integrated DMOS driver designed for three-phase brushless DC (BLDC) motors. It combines isolated DMOS power transistors with CMOS and bipolar circuits on a single chip, utilizing BCDmultipower technology. The device includes a constant off-time PWM current controller and decoding logic for single-ended hall sensors to generate the required sequence for the power stage.
Key features include non-dissipative overcurrent detection and protection on the high-side power MOSFETs, thermal shutdown, and under-voltage lockout. The device operates with a supply voltage ranging from 8 to 52 V and can deliver a peak output current of 2.8 A. It is available in a VFQFPN-32 5x5 mm package.
