SystemLensDriverSeriesforDigitalStillCameras/Single-lensReflexCameras 6ch System Lens Drivers for Digital Still Cameras / Single-lens Reflex Cameras BD6373GW,BD6873KN,BD6753KV ● Description The BD6373GW motor driver provides 6 Full-ON Drive H-bridge channels. The BD6873KN motor driver provides 5 Full-ON Drive H-bridge channels and 1 Linear Constant-Current Drive H-bridge channel, while the BD6753KV provides 4 Full-ON Drive channels and 2 PWM Constant-Current Drive H-bridge channels. Stepping motors can be used for auto focus, and either zoom or iris. A new drive type (lens barrier) is also available. Three types of drivers for shutter are offered: a simple Full-ON type, a high-precision linear constant current type, or a high-efficiency PWM constant current type, enabling selection of the ideal solution based on the application. ● Features 1) Subminiature 31PIN Wafer-level CSP (Chip Size Package): 2.6 x 2.6 x 0.85mm 3 (BD6373GW) 2) DMOS output allowing a range power supply: 4.5V to 10.5V (BD6753KV; VM1), 2.0V to 10.5V (BD6753KV; VM2 to VM4) 3) Low ON-Resistance Power MOS output: Full-ON Drive block with 1.2Ω Typ. (BD6373GW) Full-ON Drive block with 1.2Ω Typ. and Linear Constant-Current Drive block with 1.0Ω Typ. (BD6873KN) Full-ON Drive block with 1.2Ω Typ. and PWM Constant-Current Drive block with 1.2Ω Typ. (BD6753KV) 4) Serial interface 3-line bus control input (BD6753KV) 5) Built-in two-step output current setting switch for the Linear Constant-Current Drive block (BD6873KN) 6) Drive mode switching function 7) 1.2V±3% high-precision reference voltage output (BD6873KN) 8) Constant-Current Drive block features phase compensation capacitor-free design (BD6873KN) 9) Built-in ±3% high-precision Linear Constant-Current Driver (BD6873KN) 10) Built-in peak current control PWM Constant-Current Driver (BD6753KV) 11) Built-in charge pump circuit for the DMOS gate voltage drive (BD6753KV) 12) UVLO (Under Voltage Lockout Protection) function 13) Built-in TSD (Thermal Shut Down) circuit 14) Standby current consumption: 0μA Typ. ● Absolute Maximum Ratings Parameter Symbol Limit Unit BD6373GW BD6873KN BD6753KV Power supply voltage VCC -0.5 to +6.5 0 to +7.0 -0.5 to +7.0 V Motor power supply voltage VM -0.5 to +6.5 0 to +7.0 -0.5 to +12.5 V Charge pump voltage VG - - 18.0 V Control input voltage VIN -0.5 to VCC+0.5 0 to VCC -0.5 to VCC+0.5 V Power dissipation Pd 940※ 1 950※ 2 1125※ 3 mW Operating temperature range Topr -25 to +85 -25 to +85 -25 to +75 °C Junction temperature Tjmax +150 +150 +150 °C Storage temperature range Tstg -55 to +150 -55 to +150 -55 to +150 °C H-bridge output current Iout -800 to +800※ 4 -800 to +800※ 4 -800 to +800※ 4 mA/ch ※ 1 Reduced by 7.52mW/°C over 25°C, when mounted on a glass epoxy board (50mm x 58mm x 1.75mm; 8layers). ※ 2 Reduced by 7.6mW/°C over 25°C, when mounted on a glass epoxy board (70mm x 70mm x 1.6mm). ※ 3 Reduced by 9.0mW/°C over 25°C, when mounted on a glass epoxy board (70mm x 70mm x 1.6mm). ※ 4 Must not exceed Pd, ASO, or Tjmax of 150°C.
