L6235PD013TR Datasheet PDF - ST Microelectronics

●The L6235 device is a DMOS fully integrated 3-phase motor driver with overcurrent protection.

●Realized in BCDtechnology, 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 PowerDIP24 (20 + 2 + 2), PowerSO36 and SO24 (20 + 2 + 2) packages, the L6235 device features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
