Bi-CMOS IC

For Camera Modules

LV8483CS

Composite Channel Lens Driver

Overview

LV8483CS is a constant current driver IC for voice coil motors (VCM) that includes a constant current 1.5-channel driver.

It uses an ultraminiature wafer level package (WLP), which makes the IC ideal for VCM motor, shutter (SH), and iris (IR)

drivers used in a wide variety of portable equipment including camera cell phones.

Functions

• Constant current driver for AF VCM + constant current 1.5-channel H-bridge driver for SH and IR

• I²C bus interface

• Low power consumption achieved using MOS process technologies

• Built-in 4-bit DAC for constant current operation (used for SH and IR H-bridges)

• Built-in 10-bit DAC for constant current control (used for AF VCM driver)

• Built-in constant current detection resistance

• Wafer level package. WLP10 (0.97mm × 2.47mm × 0.5mmt)

• Built-in thermal shutdown circuit and LVS circuit.

• AF VCM overshoot prevention function (current slope function)

• Built-in SH/IR control pin (energization timing control function using trigger input)
