BD6735FV, BD6736FV
●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.

Bypass filter Capacitor for

Connecting capacitors between the CPL1 and CPL2, CPH1 and CPH2, and BST and GND pins generate a
BST voltage. Use caution to ensure that the voltage differential between BST and VM is 3.0V or higher, and that
the BST voltage does not exceed the absolute maximum rating of 15V, especially set the BST voltage direct
input.(p.5/8)
