DMOS dual full bridge driver

The L6226 is a DMOS dual full bridge designed for motor control applications, realized in MultiPower-BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6226 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

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