LV8095LQ
Bi-CMOS IC
For VCMs
Constant-current Driver IC
Overview
The LV8095LQ is a constant current driver IC for voice coil motors. It supports I2C control and integrates a digital/analog
converter (DAC).
Its ultraminiature package makes the IC ideal for constant-current driving the voice coil motors (AF and ZM) used in a
wide variety of portable equipment including camera cell-phones.
Features
• Constant current driver for voice coil motors.
• Constant current control enabled by DAC (8 bits).
• I2C bus control supported.
• Wide operating voltage range (2.5 to 5.5V).
• No external capacitors needed (capacitor-less).
• Ultraminiature package (USLP8 : 2.0×1.3×0.56mm) for easy soldering.
• Built-in thermal protection circuit.
• Built-in voltage drop protection circuit.
