BD6757KN Datasheet | ROHM

System Lens Driver Seriesfor Digital Still Cameras/Single-lens Reflex Cameras 7ch System Lens Drivers for Digital Still Cameras/Single-lens Reflex Cameras BD6757KN, BD6889GU No.09014EAT04 - Description BD6757KN and BD6889GU motor drivers provide 6 Full-ON Drive H-bridge channels and 1 Linear Constant-Current Drive H-bridge channel. Stepping motors can be used for the auto focus, zoom, and iris, making it possible to configure a sophisticated, high precision lens drive system. ROHM’s motor drivers are both pact, multifunctional, and enable advanced Features such as lens barrier and anti shock. - Features 1) Subminiature grid array package: 5.0  5.0  1.2mm3 (BD6889GU) 2) DMOS output allowing a range power supply: 2.0V to 8.0V (BD6757KN) 3) Low ON-Resistance Power MOS output: Full-ON Drive block with 1.3Ω Typ. and Linear Constant-Current Drive block with 0.9Ω Typ. (BD6757KN, BD6889GU) 4) Built-in two digital NPN transistor circuits for photo-interrupter waveform shaping: Input-dividing type with output pull-up resistance (BD6757KN) 5) Built-in four digital NPN transistor circuits for photo-interrupter waveform shaping: Input-dividing type with output pull-up resistance (BD6889GU) 6) Built-in four digital PNP transistor circuits for photo-interrupter waveform shaping: Input-dividing type with output pull-down resistance (BD6889GU) 7) Built-in voltage-regulator circuit for photo-interrupter (BD6889GU) 8) Built-in two-step output current setting switch for the Linear Constant-Current Drive block (BD6757KN) 9) 0.9V±2% high-precision reference voltage output 10) Constant-Current Drive block Features phase pensation capacitor-free design 11) Built-in ±3% high-precision Linear Constant-Current Driver 12) Built-in charge pump circuit for the DMOS gate voltage drive(BD6757KN) 13) UVLO (Under Voltage Lockout Protection) function 14) Built-in TSD (Thermal Shut Down) circuit 15) Standby current consumption: 0μA (Typ.) -...
