This document introduces the System Lens Driver Series for Mobile Phone Cameras from ROHM. The series includes models such as BD6883GUL, BH6453GUL, BD6886GUL, and BD6369GUL, which are used in auto focus systems for mobile phone cameras. The drivers feature ultra-small chip size, low ON-resistance, ESD resistance, built-in constant-voltage driver, and protection functions such as UVLO and TSD.

The BH6456GUL is a small lens driver from ROHM that uses a 2-wire serial interface and is compatible with I2C BUS. It is used in auto focus systems using a Piezo actuator. This lens driver has a low on-resistance, a built-in 15MHz oscillator, under voltage lockout (UVLO), thermal shutdown (TSD) circuit, and a standby current consumption of 0μA. This product is suitable for auto focus systems in mobile phone cameras.

The BH6578FVM and BD7931F are reversible motor drivers with a wide output dynamic range, with power MOS used for the output transistor. The motor drivers can set the output mode to four modes of normal rotation, reverse rotation, stop (idling), and braking in accordance with input logic (2 inputs).

BH6717NUV is a three-phase full-bridge motor driver that supports PWM signal speed control, sensorless drive, soft switched drive and power save function.
