PT5114 5+1CH DSC Motor Driver DESCRIPTION FEATURES PT5114 is a 5+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has one micro-stepping driver, two full-swing/constant voltage drivers and one full-swing/constant current drivers. PT5114 can be operated in serial control mode or partial exterior contro mode. When operating in partial exterior control mode, the mode of each CH is fixed by initial serial control setting. When operating in serial control mode, the mode of each driver can be setting by serial control. Performance is specified for -20℃ to +85℃ temperature range. • Built-in one micro-steps drive mode is possible from 2-2 phase stepper drive to maximum 256 resolution micro-steps • Built-in 2 full-swing/constant voltage drivers switched by serial control with brake function • Built-in 1 constant current drivers for shutter or IRIS selected • Low on-resistance (1.2Ω, sum of on-resistance of upside and bottom side) • Output current ΚIout<=0.8A(max.) for each channel • Built-in thermal shutdown (TSD, 150°C) • All power supply systems (VCC, VM12, VM3,VM45) can be set up with an independent power supply • Power save mode corresponds by serial control setup • PI (photo interrupter drive) 3 channel built-in • Small 28QFN (4×4mm) is adopted • Built-in POR (power on reset) APPLICATIONS • Stepping motor driver/ DC motor driver motor driver for DSC BLOCK DIAGRAM BIAS Low voltage detection TSD VREF (1.25V), POR 10uF VM12 10uF OUT1A OUT1B Serial Interface SLD OSCIN 1CH and 2CH are micro stepping OUT2B VM3 MOB MCU OUT2A PI1 Logic 3 Serial Interface Level Shift & Pre Driver 3CH CV/FS OUT3A OUT3B PI2 Serial Interface Control signal PI3 4Bit DAC VC3 Thermal PAD VM45 IN3 IN4 IN5 Selector Logic 4 Serial Interface Serial Interface Level Shift & Pre Driver 4Bit DAC 4CH CV/FS OUT4A OUT4B VC4 ZOOM/IRIS SCLK Level Shift & Pre Driver ZOOM/IRIS (DCM/COIL) SDAT Logic 12 Serial Interface Serial control signal (3Wire) EXT AutoFocus(STM-1) VCC ZOOM/IRIS/Shutter (DCM/COIL) Vcc Power supply VM Power supply DGND Logic 5 Serial Interface Serial Interface Level Shift & Pre Driver 4Bit DAC 5CH CC VC5 OUT5A OUT5B Shutter (COIL) RNF5 Notes: 1.
