Product Overview

The L6235D is a 3-phase DMOS fully integrated 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. It features a non-dissipative overcurrent detection and protection on the high-side power MOSFETs and thermal shutdown.
  • Diagnostic output
  • Constant tOFF PWM current controller
  • Slow decay synchronization rectification
  • 60° and 120° Hall-effect decoding logic
  • Brake function
  • Tachometer output for speed loop
  • Cross conduction protection
  • Under-voltage lockout
  • Integrated fast free-wheeling diodes
  • Operating frequency up to 100kHz
  • 0.3Ω at Tj=25°C RDS(ON)
