PT5111 6+1CH DV/DSC Motor Driver DESCRIPTION FEATURES The PT5111 is a semiconductor integrated circuit that incorporates driver circuits suitable for the motors of digital cameras. The current consumption can be hold at quite low level during standby or operation. And the active power supply voltage range for VM is from 2.7~5.5V. So the device is ideal for portable and battery powered applications. The PT5111 is available in QFN40 (5mm × 5mm) package. Performance is specified for -20℃ to +75℃ temperature range. • An ultra-fine CMOS process has been adopted for low power consumption in a design. • A small 40-pin QFN package(5mm×5mm, lead pitch is 0.4 mm)has been adopted. • 1ch/2ch and 3ch/4ch are capable of micro-steps mode. Possible modes are from 2-2 phase stepper drive to maximum 256 resolution micro-steps. • Built-in autonomous drive circuit under the control of serial settings. • Built-in 3-ch PI driver • Under voltage lockout circuit - Shut down the internal circuit at VCC=1.8V (Typ.) • Thermal shut down circuit - Shut down the internal circuit at 150℃ Hysteresis 30℃ • Power supply systems are all internally isolated and include a function to prevent reverse current between power supplies. • Built-in exclusive control mode from channel 3 to channel 6.(resemblance 7 channel motor drive application) APPLICATION • DSC/DV BLOCK DIAGRAM Control MCU 2.7~3.6V 10uF VCC Power supply Reset H:Active Serial Control Base Clock L:Standby (3wire) Shutter Control EXT2/ST2 MOB2 EXT1/ST1 OSCIN MOB1/SDO SDAT CS SCLK RESET PI1 PI2 IN3 IN4 IN6 BIAS Low voltage detection TSD VREF(1.25V) IN5 PI3 VCC Serial Control Logic DAC Resolution of up to 256 mocro-step PWM Control OUT1A DGND PGND12 OUT1B 1CH BTLAMP H Bridge VM12 OUT2B OUT2A 2CH BTLAMP H Bridge OUT3A 3CH BTLAMP H Bridge OUT3B VM34 OUT4A OUT4B PGND34 4CH BTLAMP H Bridge VM5 OUT5A OUT5B 5CH FS/CC H Bridge VM Power supply ZOOM (COIL) IRIS (STM) AF (STM) 10uF SHUTTER (COIL) ( ) VM6 OUT6A OUT6B RNF6 6CH CC H Bridge PGND5(RNF5) Exclusive Control Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, 233-1, Baociao Road, Sindian, Taipei 23145, Taiwan PT5111 1.
