Supply Infineon Motor Driver IC TLE8444SL Quad Half-Bridge Driver IC

Product Description
TLE8444SL is a protected Quad-Half-Bridge-IC targeted towards automotive and industrial motion control applications. TLE8444SL is a monolithic die based on 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 StepperMotors 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.

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
Inverted and Non-inverted Inputs to minimize number of microcontroller connections
Very low current consumption in sleep mode (max. 5µA)
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)

Applications
Unipolar or Bipolar Loads
Stepper Motors (e.g. Idle Speed Control)
DC brush Motors
