1. general description the SA56203S is a one-chip motor driver ic that is capable of driving all motors of cd or dvd systems e.g. spindle, sled and loading motors and actuators on the optical pick-up unit. the driver intended for the 3-phase, brushless, hall-commutated spindle motor uses true-silent pwm. this proprietary technology ensures that all 3-phase motor currents are sinusoidal resulting in an optimally silent driver. internal regeneration of the back emf of the spindle motor enables the driver to operate in current-steering mode without using external power-dissipating sense resistors. the driver for the 2-phase sled stepper motor operates in current-steering pwm mode. in addition the ic contains four full-bridge linear channels that can be used to drive a loading motor and 3d actuators (focus, tracking and tilt). the SA56203S is available in an exposed die pad htssop56 package. 2. features n true-silent pwm spindle motor driver n low heat generation due to power-ef?cient direct full-bridge switching of spindle motor driver n controlled spindle motor current during acceleration and brake n reverse torque brake function (full bridge) n adjustable spindle motor current limiter n internal regeneration for emf of spindle motor n current-steering pwm controlled stepper motor driver for sled n four class-ab linear channels for loading motor and 3d actuators (focus, tracking and tilt) n tracking actuator driver with back emf ampli?er n loading motor driver with transresistance ampli?er for loading current n low on-resistance d-mosfet output power stages n built-in thermal shutdown and thermal warning n interfaces to 3 v and 5 v logic n package with low thermal resistance to heatsink (re?owable die pad) n lead free package.

[2] the motor current limit of the spindle is tested by applying vinspn = 0 v and 3.3 v, measuring the duty cycles on the u, v a nd w spindle driver outputs and calculating the corresponding motor currents with the applied 12 v supply voltage and the 2.5 w motor, switches and wiring resistance. [3] the transconductance gain of the spindle is tested by applying vinspn = 0 v and 3.3 v and calculating the corresponding moto r currents (see t ab le note 2 ) and determining the slope (see figure 3 ). [4] the sled motor is tested loaded with r l = 4 w in series with l l = 1 mh. [5] the transconductance gain of the sled motor driver is tested as: g m = {(i sldo - at v vinsld = 1.85 v) - (i sldo - at v vinsld = 1.45 v)}/0.4 v. [6] the voltage gain of the loading motor driver is tested as: g v = {(v ldo+ - v ldo - at v vinld = 2.4 v) - (v ldo+ - v ldo - at v vinld = 0.9 v)}/1.5 v. [7] the voltage gain of the actuator driver is tested as: g v = {(v acto+ - v acto - at v vinact = 2.4 v) - (v acto+ - v acto - at v vinact = 0.9 v)}/1.5 v. [8] the gain mismatch is related to the absolute gain; an absolute gain of 8 (18 db) corresponds with a maximum mismatch of 0.4 (5 %) and an absolute gain of 4 (12 db) corresponds with a maximum mismatch of 0.2 (5 %). [9] the voltage gain of the back emf voltage tracking actuator is tested as: g v = {(v vldtrk at v trko+ = 1.03 v and v trko - = 1.00 v) - (v vldtrk at v trko+ = 1.00 v and v trko - = 1.03 v)}/0.06 v. temperature protection: pin temp t temp thermal warning temperature - 150 - c t hys(temp) thermal warning hysteresis -20 - c t sd thermal shutdown temperature - 160 - c t hys(sd) thermal shutdown hysteresis -30 - c table 8: characteristics continued v dda = 5 v; v dd1(spn) = v dd2(spn) = 12 v; v dd(sld) = 12 v; v dd(trk) = 12 v; v dd(act) = 5 v; v dd(ld) = 12 v; t amb = 25 c; all characteristics are speci?ed for the default settings (see t ab le 9 ); all voltages are referenced to v ss ; positive currents ?ow into the device; unless otherwise speci?ed. symbol parameter conditions min typ max unit table 9: default settings pin default setting hu+, hv+ 5 v hw+ ground hu - , hv - , hw - 1.650 v hbias open-circuit rref 47 k w to v ss , ?xed value, should not be changed remf 12 k w to v ss rlim 20 k w to v ss v ss1(spn) , v ss2(spn) ground u, v, w open-circuit v dd1(spn) , v dd2(spn) 12 v supply fg open-circuit v ssa ground vinspn, vinref 1.65 v v dda 5 v supply

9397 750 14192 ? koninklijke philips electronics n.v. 2005. all rights reserved. preliminary data sheet rev. 01 31 january 2005 26 of 30 philips semiconductors SA56203S one-chip motor driver C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. ? for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be ?xed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 c or 265 c, depending on solder material applied, snpb or pb-free respectively. a mildly-activated ?ux will eliminate the need for removal of corrosive residues in most applications. 15.4 manual soldering fix the component by ?rst soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the ?at part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 seconds to 5 seconds between 270 c and 320 c. 15.5 package related soldering information [1] for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales of?ce. [2] all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . [3] these transparent plastic packages are extremely sensitive to re?ow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared re?ow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the re?ow oven. the package body peak temperature must be kept as low as possible. table 10: suitability of surface mount ic packages for wave and re?ow soldering methods package [1] soldering method wave re?ow [2] bga, htsson..t [3] , lbga, lfbga, sqfp, ssop..t [3] , tfbga, vfbga, xson not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable [4] suitable plcc [5] , so, soj suitable suitable lqfp, qfp, tqfp not recommended [5] [6] suitable ssop, tssop, vso, vssop not recommended [7] suitable cwqccn..l [8] , pmfp [9] , wqccn..l [8] not suitable not suitable

[5] if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. [6] wave soldering is suitable for lqfp, qfp and tqfp packages with a pitch (e) larger than 0.8 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. [7] wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. [8] image sensor packages in principle should not be soldered. they are mounted in sockets or delivered pre-mounted on ?ex foil. however, the image sensor package can be mounted by the client on a ?ex foil by using a hot bar soldering process. the appropriate soldering pro?le can be provided on request. [9] hot bar soldering or manual soldering is suitable for pmfp packages.
