SystemLensDriverSeriesforDigitalStillCameras/Single-lensReflexCameras
1 to 2ch Lens Drivers
for Single-Lens Reflex Cameras
BD6735FV, BD6736FV
No.09014EAT03
●Description
The BD6735FV motor driver provides 2 Full-ON Drive H-bridge channels, while BD6736FV provides 1 Full-ON Drive H-bridge
channel. ROHM’s lens driver series features high voltage resistance and large current output in a compact surface mount
package, making it ideally suited for smaller systems such as Single-Lens Reflex with Interchangeable Lenses.
●Features
1) Low ON-Resistance Power MOS output: Full-ON Drive block with 1.0Ω Typ. (BD6735FV)
Full-ON Drive block with 0.35Ω Typ. (BD6736FV)
2) DMOS output allowing a range power supply: 2.0V to 8.0V (BD6735FV), 2.0V to 9.0V (BD6736FV)
3) Built-in step-up circuit for the DMOS gate voltage drive
4) Drive mode switching function
5) H bridge maximum output current: DC maximum 1.0A (BD6735FV and BD6736FV), Peak maximum 3.2A (BD6736FV)
6) UVLO (Under Voltage Lockout Protection) function
7) Built-in TSD (Thermal Shut Down) circuit
8) Standby current consumption: 0μA Typ.
