The Freescale Semiconductor MC33970DWR2 is a single-packaged, Serial Peripheral Interface (SPI) controlled, dual step motor gauge driver integrated circuit. This monolithic IC consists of four dual output H-Bridge coil drivers and associated control logic, designed for automatic control of speed, direction, and current magnitude in two-phase instrumentation step motors.
Ideal for automotive instrumentation systems, the MC33970DWR2 provides distributed and flexible step motor gauge driving. It supports air core motor emulation, easing the transition to step motors with minimal processor overhead. Key features include 4096 possible steady-state pointer positions, a 340° maximum pointer sweep, and fixed maximum acceleration/deceleration of 4500°/s².
This device operates within a temperature range of -40°C to 125°C and comes in a 24-pin SOICW surface mount package. It offers analog microstepping with 12 steps per degree of pointer movement, pointer calibration, and return to zero functionality. The SPI-controlled 16-bit word interface simplifies integration into existing designs.
The MC33970DWR2 has a maximum pointer sweep of 340 degrees.
The MC33970DWR2 has a fixed maximum acceleration of 4500 degrees per second squared.
The maximum pointer velocity for the MC33970DWR2 is 400 degrees per second.
The MC33970DWR2 operates in a temperature range of -40°C to 125°C.
The MC33970DWR2 is supplied in a 24-pin SOICW package for surface mounting.
