Product Overview

EVAL6235PD is a fully integrated L6235 three phase brushless DC motor driver demonstration board. Realised in multiPower 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 three phase BLDC motor including: a three 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. The evaluation board provides external connectors for the supply voltage, an external 5V reference for the logic inputs, three outputs for the motor and a 34 pin connector to control the main functions of the board through an external microcontroller board. The speed information is obtained by analog integration of the TACHO output. Board is designed with a large GND area to minimize noise and optimize power dissipation.
  • Operating supply voltage from 8V to 52V
  • 5.6A output peak current(2.8A DC)
  • Operating frequency up to 100KHz
  • Non dissipative overcurrent detection and protection
  • Diagnostic output, Thermal shutdown, Undervoltage lockout
  • Constant Toff PWM current controller
  • Slow decay synchronous rectification
  • Integrated hall sensor decoding logic(60/120 degrees)
  • Brake function, Cross conduction protection
  • Tacho output for speed loop, integrated fast free wheeling diodes
