1 / 8 page Ordering number : ENA1515 Bi-CMOS IC For VCMs Constant-current Driver IC LV8098CS Overview The LV8098CS is a constant current driver IC for voice coil motors that supports I 2C 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 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. • Constant current control enabled by DAC (8 bits). • I2C bus control supported. • 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.
