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 .

Switching noise from PCB traces, where high current flows, to the VDD line should be minimized because the noise level more than 0.5V on the VDD line may cause malfunctioning operation. The tip for avoiding such problem is to separate the logic GND (S-GND) and the power GND (P-GND) on a PCB, and then connect them together at IC GND pin (#11). ☆The loss of ‘Rs’ resistance will occur. .

IO = V REF RS REF voltage is recommended to be from 0.1 to 1.0V. ※When the REF<0.1V,the accuracy of the current control becomes worst. Moreover, setting the REF voltage more than 2V activates the sleep mode (all outputs is in OFF state). However, the internal logic circuit is alive. Logic inputs/output (RESET, CLOCK, CW/CCW, M1, M2, SYNC, Mo) ・Following timing should comply with the "Logic input timing". -The rising edge timing of CW/CCW, M1, M2 and that of CLOCK input -The RESET release timing(=the falling edge on RESET input) and the rising edge timing of CLOCK input ※In case it does not comply with the "Logic input timing", it may operate at an unexpected sequence. ・Be sure to prevent the logic inputs(RESET, CLOCK, CW/CCW, M1, M2, SYNC) from being "OPEN". If some of the logic inputs are not used, be sure to connect them to VDD or GND. ※In case some of the logic inputs stay "OPEN", a malfunction may occur due to external noises. ・When the logic output(Mo) is not used, be sure to keep it "OPEN". ※In case it is connected to VDD or GND, it may cause the device's deterioration or/and breakdown. Installation to a heat sink 0.490～0.822N•m 1) Recommended Clamping Torque (to External Heat sink) ｛SHIN-ETSU CHEMICAL｝ 2) Recommended Silicone G746 YG6260 ｛TOSHIBA SILICONE｝ ｛DOW CORNING TORAY SILICONE｝ SC102 Notice This driver has C-MOS inputs. Please notice as following contents. ・When static electricity is a problem, care should be taken to properly control the room humidity. This is particularly true in the winter when static electricity is most troublesome. ・Care should be taken with device leads and with assembly sequencing to avoid applying static charges to IC leads. PC board pins should be shorted together to keep them at the same potential to avoid this kind of trouble. . Sanken Electric Co.,Ltd.
