DMOS dual full bridge driver

The L6226Q is a DMOS dual full bridge designed for motor control applications, realized in BCDmultipower technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. Available in QFN32 5x5 package, the L6226Q features thermal shutdown and a non-dissipative overcurrent detection on the high side power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.

Key Features

  • Operating supply voltage from 8 to 52 V
  • 2.8 A output peak current (1.4 A DC)
  • RDS(on) 0.73 Ω typ. value @ TJ = 25 °C
  • Operating frequency up to 100 kHz
  • Programmable high side overcurrent detection and protection
  • Diagnostic output
  • Paralleled operation
  • Cross conduction protection
  • Thermal shutdown
  • Under voltage lockout
  • Integrated fast free wheeling diodes
