LV8099CS

Ordering number : ENA1533 www.DataSheet4U.com Bi-CMOS IC LV8099CS Overview For VCMs Constant-current Driver IC The LV8099CS 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 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). Functions Constant current driver for voice coil motors. Constant current control enabled by DAC (10 bits). 2 I C bus control supported. Wide operating voltage range (2.2 to 5.0V). Built-in current detection resistor. 6-pin WLP package used (1.27 × 0.87 × 0.5mm). Built-in voltage drop protection circuit (VCC = 2V output off). Built-in thermal protection circuit. Low output block total-resistance of 2Ω helps withstand voltage drop in VCC. (Current detection resistance + output transistor on-resistance). Built-in VCM overshoot preventive functio...
