LV8098CS
Bi-CMOS IC
For VCMs
Constant-current Driver IC
Overview
The LV8098CS is a constant current driver IC for voice coil motors that supports I2C control integrating a digital/analog
converter (DAC). It uses an ultraminiature WLP package and includes a current detection resistor for constant current
control, which makes the IC ideal for miniaturization of camera modules intended for use in camera-equipped mobile
phones. The output transistor has a low on-resistance of 1Ω and the resistance of the built-in current detection resistor is
1Ω, which minimizes the voltage loss and helps withstand voltage drop in VCC. The current consumption when the DAC
is set to code 0 is 0 (ICC ≈ 0, IOUT ≈ 0) allowing reduction in current consumption.
Functions
• Constant current driver for voice coil motors.
• I2C bus control supported.
• Constant current control enabled by DAC (8 bits).
• Wide operating voltage range (2.2 to 5.0V).
• The current consumption is 0 when the DAC is set to code 0. • 6-pin WLP package used (1.27 × 0.87 × 0.5mm).
• Built-in thermal protection circuit.
• Built-in voltage drop protection circuit (VCC = 2V output off).
• Low output block total-resistance of 2Ω helps withstand voltage drop in VCC. (Current detection resistance + output
transistor on-resistance).
• Built-in current detection resistor.
