PC33991 Datasheet | Freescale Semiconductor

features including: PR EL IM - - - - - - - - MMT-licensed two-phase stepper motor patible - Minimal processor overhead required - Fully integrated pointer movement and position state machine with air core movement emulation - 4096 possible steady state pointer positions - 3 40° maximum pointer sweep Linear 4500° 2 Max pointer velocity of 400° Analog micro stepping (12 steps/degree of pointer movement) Pointer calibration and return to zero SPI controlled 16-bit word Calibratable Internal Clock Low Sleep mode current DW SUFFIX PLASTIC PACKAGE CASE 751E-04 SOICW This device is ideal for use in automotive instrumentation systems requiring distributed and flexible stepper motor gauge driving. The device also eases the transition to stepper motors from air core motors by emulating the air core pointer movement with little additional processor bandwidth utilization.
