Infineon TLE8444SL product picture

The TLE 8444SL is a protected Quad-Half-Bridge-IC targeted towards automotive and industrial motion control applications. It is a monolithic die based on Infineon’s smart mixed technology SPT which combines bipolar and CMOS control circuitry with DMOS power devices. DC-Motors can be driven in forward (cw), reverse (ccw), brake and high impedance modes where as Stepper- Motors can be driven in No-Current, negative / positive output current modes. These various modes can easily be achieved via standard parallel interface of the device to a microcontroller.

 

Key features

  • 4 Half-Bridge Power Outputs (1.3Ω RDS(ON) MAX @ Tj=150°C)
  • Minimum Overcurrent Shutdown at 0.9A
  • Simple parallel interface control of Half-Bridge Outputs
  • Very low current consumption in sleep mode (max. 5μA)

 

Additional features

  • Inverted and Non-inverted Inputs to minimize number of microcontroller connections
  • Error Flag Diagnosis
  • Open Load Diagnosis in ON-state for all outputs
  • Outputs protected against overcurrent
  • Over temperature protection with hysteresis
  • Over and Under voltage lockout
  • 3.3V / 5V compatible inputs with hysteresis
  • No crossover current
  • Internal freewheeling diodes
  • Thermally enhanced package (fused leads)
  • Green Product (RoHS compliant)
  • AEC Qualified
  • Small package helps to save PCB area
  • Improved diagnosis for over- and under voltage-lockout and open load detection improve system reliabiltiy and performance
  • The device also supports stepper motor applications


Applications

  • DC motors in automotive and industrial applications
  • Stepper Motors in autmotive and industrial applications
  • e.g. Idle speed control for small cars/ motor bikes
