1 / 14 page 2-Phase Unipolar Stepper Motor Driver SLA7050M/7051M/7052M October 2005 Sanken Electric Co.,Ltd. I03-002EA-051006 ■General Description Combining low-power CMOS logic with high-current, high-voltage power FET outputs, the Series SLA705xM translator/driver provides complete control and drive for a two-phase unipolar stepper motor with internal fixed off time, pulse-width modulation (PWM) control of the output current in a power multi-chip module (PMCM™). The CMOS logic section provides the sequencing logic, direction, full/half-step 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 and withstanding 46 V in the off state. Ground-clamp and flyback diodes provide protection against inductive transients. Special power-up sequencing is not required. Full-step (2 phase) and half-step operation are externally selectable. Two-phase drive energizes two adjacent phases in each detent position (AB-BC-CD-DA). This sequence mode offers an improved torquespeed product, greater detent torque, and is less susceptable to motor resonance. Half-step excitation alternates between the one-phase and two-phase modes (A-AB-B-BC-C-CD D-DA), providing an eight-step sequence. ■Package----SLA18Pin ■Applications ●PPC ●Printer ●OA Equipment ■Features ●To 3A Output Rating ●Internal Sequencer for Full or Half-Step Operation ●PWM Constant-Current Motor Drive ●Cost-Effective, Multi-Chip Solution ●100 V, Avalanche-Rated NMOS ●Low rDS(on) NMOS Outputs (300 milli-ohms typical) ●Advanced, Improved Body Diodes ●Half-Step and Full-Step Unipolar Drive ●Inputs Compatible with 3.3 V or 5 V Control Signals ●Sleep Mode ●Internal Clamp Diodes ■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(SLA7050M) 2A(SLA7051M) 3A(SLA7052M) ●Output Maximum Voltage (VDSS):100V min Typical Connection 7050 SLA M 7051 SLA M 7052 SLA M マイコン 等 18 13 16 14 4 15 5 7 8 9 11 12 6 2 17 13 Vs GA NC OutA OutA/ OutB OutB/ Vcc Clock Sync CW/CCW Full/Half Ref SenseB SenseA Gnd 10 r1 r2 Disable Q1 RsA RsB + + CA CB ~ Vs=10V 44V ~ Vcc=3.0V 5.5V S-Gnd P-Gnd Gnd NC GB http://www.sanken-ele.co.jp/en/ 1/14 |
