LV8098CS Overview
Ordering number : ENA1515 .. Bi-CMOS IC LV8098CS Overview For VCMs Constant-current Driver IC 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
