LV8483CS
Overview
For Camera Modules posite Channel Lens Driver
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...
