2-Phase Unipolar Stepper Motor Driver .. SLA7060M/61M/62M/65M/66M/67M October 2005 - General Description bining low-power CMOS logic with high-current, high-voltage power FET outputs, the Series SLA706x M translator/drivers provide plete control and drive for a two-phase unipolar stepper motor with internal fixed off time and pulse-width modulation (PWM) control of the output current in a power multi-chip module (PMCM™). There are no phase-sequence tables, high-frequency control lines, orplex interfaces to program.The CMOS logic section provides the sequencing logic, direction,control, synchronous/asynchronous PWM operation, and a "sleep"function. The minimum CLOCK input is an ideal fit for applications where a plex µP is unavailable or overburdened. TTL or LSTTL may require the use of appropriate pull-up resistors to ensure a proper input-logic high. For PWM current control, the maximum output current is determined by the user's selection of a reference voltage and sensing resistor. The NMOS outputs are capable of sinking up to 1, 2, or 3 A (depending on device) and withstanding 46 V in the off state. Clamp diodes provide protection against inductive transients. Special power-up sequencing is not required. Half-, quarter-, eighth-, and sixteenth-step operation are externally selectable for the SLA7060/61/62M. Full-, Half-, quarter-, and eighth-step operation are externally selectable for the SLA7065/66/67M. Half-step excitation alternates between the one-phase and two-phase modes (A-AB-B-AB-A-AB-BAB),providing an eight-step sequence. - Package - Applications - PPC - Printer - OA Equipment - Key Specifications - Motor Supply Voltage (VM)：44V max - Load Supply Voltage (Vs)：10V～44V - Logic Supply Voltage (Vcc)：3V～5.5V - Output Current (Io)：1A(SLA7060M,SLA7065M) 2A(SLA7061M,SLA7066M) 3A(SLA7062M,SLA7067M) - Output Maximum Voltage (VDSS)：100V min - Features - To 3 A Output Rating - Internal Sequencer for Microstepping Operation - PWM Constant-Current...
