  • 2.8 A output peak current (1.4 A DC).
  • RDS(ON) 0.73 Ω typ. value at Tj = 25 °C.
  • Operating frequency up to 100 kHz.
  • Non-dissipative overcurrent detection and protection.
  • Diagnostic output.
  • Constant tOFF PWM current controller.
  • Slow decay synchronous rectification.
  • 60° and 120° Hall effect decoding logic.
  • Brake function.
  • Tachometer output for speed loop.
