MC33976DW

The MC33976DW is a type of single-packaged, Serial Peripheral Interface (SPI) controlled, dual step motor gauge dri ver integrated circuit (IC). MC33976DW includes four dual output H-Bridge coil drivers and the associated control logic. Each pair of H-Bridge drivers is utilized to automatically control the speed, direction, and magnitude of current through the two coils of a two-phase instrumentation step motor, same with an MMT-licensed AFIC 6405 or Switec MS-X15.xxx motor.

Features of MC33976DW are:(1)MMT-licensed two-phase step motor compatible; (2)switec MS-X15.xxx step motor compatible; (3)minimal processor overhead required; (4)fully integrated pointer movement and position statemach ine with channel-independent configurable pointer movement; (5)4096 possible steady state pointer positions; (6)340°maximum pointer sweep; (7)maximum acceleration of 4500°/s; (8)maximum pointer velocity of 400°/s; (9)analog microstepping (12 steps/degree of pointer movement), etc.

The absolute maximum ratings of the MC33976DW can be summarized as: (1)power supply voltage(steady state):-0.3V to 41V; (2)input pin voltage:-0.3V to 7.0V; (3)sin+/- cos +/- continuous per output current: 40mA; (4)storage temperature:-55°C to 150°C; (5)operating junction temperature:-40°C to 150°C; (6)thermal resistance(ambie nt): 60°C/W;thermal resistance(junction to lead): 20°C/W; (7)ESD voltage(human body mode): ±2000V;ESD volta ge(machine model): ±200V.
