SLA7060M

2-Phase Unipolar Stepper Motor Driver SLA7060M/61M/62M/65M/66M/67M October 2005 ■Package ■General Description Combining low-power CMOS logic with high-current, high-voltage power FET outputs, the Series SLA706xM translator/drivers provide complete 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, orcomplex 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 complex 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. ■Applications ●PPC ●Printer ●OA Equipment ■Key Specifications ●Motor Supply Voltage (VM)：44V max ●Load Supply Voltage (Vs)：10V～44V ■Features ●Logic Supply Voltage (Vcc)：3V～5.5V ●To 3 A Output Rating ●Internal Sequencer for Microstepping Operation ●PWM Constant-Current Motor Drive ●Cost-Effective, Multi-Chip Solution ●100 V, Avalanche-Rated NMOS Outputs ●Low rDS(on) NMOS Outputs (150 milli-ohms typical) ●Advanced, Improved Body Diodes ●nputs Compatible with 3.3 V or 5 V Control Signals ●Sleep Mode ●Internal Clamp Diodes ●Output Current (Io)：1A(SLA7060M,SLA7065M) 2A(SLA7061M,SLA7066M) 3A(SLA7062M,SLA7067M) ●Output Maximum Voltage (VDSS)：100V min Typical Connection VBB=VM=10～ 44V CA µ-con M1 Mo 14 15 Sync 4 5 7 18 19 20 21 17 11 S-GND RSB SenseB RSA GND SenseA R2 3 SLA706xM Series REF R3 2 OutB M2 1 OutB/ Clock OutA 8 9 10 12 13 CW/CCW CB 16 6 Reset OutA/ C1 Q1 VBB R1 Disable VDD VDD=3.0～ 5.5V P-GND .
