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
