Constant-current Driver IC

LV8098CS

Overview

The LV8098CS is a constant current driver IC for voice coil motors that supports I

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).

• 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.
