LV8481CS
Bi-CMOS IC
Saturated Driver with 2 channels +
Constant Current Driver
Overview
The LV8481CS is low-voltage motor driver with a saturated driver with 2 channels + constant current driver.
Since it is in wafer level package, this IC is optimized for the stepping motor driver and shutter driver
of various portable equipments including the mobile phones with camera.
Functions
• Saturated driver H bridge with 2 channels + Constant current driver.
• I2C bus interface
• Built-in AF stepping motor sequence logic (enabling 2-phase excitation and 1-2 phase excitation)
• Built-in lens home position sequence logic
• Enabling power-saving by MOS process
• Built-in 4 bit DAC for constant current
• Built-in constant current detection resistance
• Wafer level package. WLP10 (0.97mm × 2.47mm × 0.5mmt)
• Built-in thermal shutdown circuit and LVS circuit.
