EVAL6235N

L6235 DMOS Driver for Three-Phase Brushless DC Motor Evaluation Board
  • active 活性

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

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