| 2-phase unipolar stepper motor driver sla7060m/61m/62m/65m/66m/67m october 2005 . sanken electric co.,ltd. i03-003ea-051006 general description combining low-power cmos logic with high-current, high-voltage power fet outputs, the series sla 706xm 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.t he 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 wh ere a complex p 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 agai nst inductive transients. special power-up sequencing is not required. half-, quarter-, eighth-, and sixt eenth-step operation are externally selectable for the sla7060/61/62 m. full-, half-, quarter-, and eighth-step operation are externally selectable for the sla7065/66/67m. half-step excitation alternates be tween the one-phase and two-phase modes (a-ab-b-ab-a-ab-bab),pr oviding an eight-step sequence. package applications ppc printer oa equipment features to 3 a output rating internal sequencer for microstepping operation pwm constant-current motor drive cost-effective, mu lti-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 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 (v dss ) 100v min typical connection sla706xm series clock cw/ccw sensea sync ref gnd outb/ outb outa outa/ v bb =v m =10 44v disable v dd =3.0 5.5v r 1 r 2 r sa r sb q 1 13 10 5 6 12 11 7 8 9 121 20 19 18 16 2 3 4 p-gnd s-gnd m1 m2 mo reset 17 14 15 r 3 c 1 senseb v bb v dd c a c b -con http://www.sanken-ele.co.jp/en/ 1/18
