Bi-CMOS IC
For Camera Modules
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)
