2-Phase Unipolar Stepper Motor Driver SLA7050M/7051M/7052M October 2005 Sanken Electric Co.,Ltd. I03-002EA-051006 ■G e n e r a l D e s c r i p t i o n 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, pul se-width modulation (PWM) control of the output current in a power multi-chip module (PMCM™). The CMOS logic section provides th e sequencing logic, direction, full/half-step control, synchr onous/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 di odes provide protection against inductive transients. Special power-up sequencing is not required. Full-step (2 phase) and half-step ope ration 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 m odes (A-AB-B-BC-C-CD D-DA), providing an eight-step sequence. ■Package----SLA18Pin ■A p p l i c a t i o n s

2-Phase Unipolar Stepper Motor Driver SLA7050M/7051M/7052M October 2005 Sanken Electric Co.,Ltd. I03-002EA-051006 Cautions and warnings The calculation of control current SLA705xM Series control current Io is calculated as follow. Io＝VREF／Rs REF Voltage range is 0.1V～1.0V ※When the REF<0.1V, the accuracy of control current is reduce. Moreover, if REF voltage is set up more than 2.0V, all outputs will be in OFF state. Installation to a heat sink 1)Recommended Clamping Torque (to External Heat sink) 0.490 ～0.822N･m 2)Recommended Silicone 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. G746 YG6260 SC102 ｛SHIN-ETSU CHEMICAL｝ ｛GE TOSHIBA SILICONES｝ ｛DOW CORNING TORAY SILICONE｝
