PC33991R2 - Gauge Driver Integrated Circuit

General Description

H-Bridge Output.

This is the output pin of a half bridge, designed to source or sink current.

The H-Bridge pins linearly drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation.

Key Features

  • including: PR EL IM IN A R.
  • MMT-licensed two-phase stepper motor compatible.
  • Minimal processor overhead required.
  • Fully integrated pointer movement and position state machine with air core movement emulation.
  • 4096 possible steady state pointer positions.
  • 340° maximum pointer sweep.
  • Linear 4500° 2 Max pointer velocity of 400° Analog micro stepping (12 steps/degree of pointer movement.

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33991/D Rev. 0, 10/2002 Preliminary Information Gauge Driver Integrated Circuit The 33991device is a single packaged, Serial Peripheral Interface (SPI) controlled, dual stepper motor gauge driver Integrated Circuit (IC). This monolithic IC consists of four dual output H-Bridge coil drivers and the associated control logic. Each pair of H-Bridge drivers is used to automatically control the speed, direction and magnitude of current through the two coils of a 2-phase instrumentation stepper motor, similar to an MMT licensed AFIC 6405. 33991 Freescale Semiconductor, Inc...
