L6230 - DMOS

Description

The L6230 is a DMOS fully integrated threephase motor driver with overcurrent protection, optimized for FOC application thanks to the independent current senses.

Realized in BCDmultipower technology, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip.

Features

  • Operating supply voltage from 8 to 52 V.
  • 2.8 A output peak current (1.4 A RMS).
  • RDS(on) 0.73  typ. value at TJ = 25 °C.
  • Integrated fast freewheeling diodes.
  • Operating frequency up to 100 kHz.
  • Non-dissipative overcurrent detection and protection.
  • Cross conduction protection.
  • Diagnostic output.
  • Uncommitted comparator.
  • Thermal shutdown.
  • Undervoltage lockout.
