| DA9012.001 25 August 2004 MAS9012 Stepper Motor Driver IC * Supports Microstepping Movement * Capable to Drive One to Four Motors * Low Operating Voltage DESCRIPTION MAS9012 is a Miniature Stepper Motor Driver IC with four different versions to drive one to four motors of pointers in motorcycle and car dashboards and other similar applications. It features a microstepping function to allow smooth movement of the motor shaft. One microstep corresponds to an angular rotation of 1/12 degree of the motor shaft. The actual precision of the position is affected by the gear play of the motor. The microstepping movement of the motor shaft is achieved by converting a pulse sequence into a current level sequence sent to the stepper motor coils. FEATURES * Bipolar Stepper Motor Driver Outputs * Drives One to Four Stepper Motors * Microstepping Function * Glitch Filters at All Inputs * Low Operating Voltage * TSSOP-16 and TSSOP-28 Packages APPLICATIONS * Motorcycle Dashboards * Car Dashboards * Nautical Instrumentation * Miniature Stepper Motors in Appliances 1 (12) DA9012.001 25 August 2004 BLOCK DIAGRAMS VDD Output Driver A FSCXA CWA Output Driver A FSCX CW Glitch Filter Glitch Filter Glitch Filter OUTA1 OUTA2 OUTA3 OUTA4 FSCXB CWB Glitch Filter Glitch Filter Glitch Filter Glitch Filter Glitch Filter Output Driver B OUTB1 OUTB2 OUTB3 OUTB4 OUTA1 OUTA2 OUTA3 OUTA4 VDD XRESET XRESET VSS MAS9012A1 VSS MAS9012A2 Figure 1.

It has four different device versions: A1, A2, A3 and A4 with single, dual, triple and quad stepper motor driver outputs respectively (see block diagrams on page 2). The IC is operated from single 5V supply. Each stepper motor output is controlled by two digital control signal inputs, FSCX and CW. Each rising edge of FSCX stepping clock input causes stepper motor to step one microstep (1/12 degree) ahead. Rotation direction is determined by CW rotation direction selection signal. High CW selects clockwise direction and low CW selects counterclockwise direction. Each stepper motor has its own FSCX and CW signal inputs. The device has common XRESET master reset control input for resetting stepper motor outputs to initial state. XRESET is active low. Each digital input has a glitch filter for eliminating effects of electrical disturbances at the control inputs. It is recommended to keep XRESET signal low (active) during power up until the supply voltage VDD has risen up. 3 (12) DA9012.001 25 August 2004 ABSOLUTE MAXIMUM RATINGS All voltages with respect to ground Parameter Supply Voltage Voltage Range for All Pins ESD Rating Junction Temperature Storage Temperature Symbol VIN Conditions Min -0.3 -0.3 Max 6 VIN + 0.3 2 +175 (limited) Unit V V kV C C HBM TJmax TS -55 +150 Stresses beyond those listed may cause permanent damage to the device.
