The LV8498CT 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 1 Ω and the resistance of the built-in current detection resistor is 1 Ω, which minimizes the voltage loss and helps withstand voltage drop in VCC. The function is incorporated, which, by changing the current in a stepped pattern while taking time at rise and fall of the output current, provides the current a slope, improving the converging stability of the voice coil motor (current slope function).
