AW8601CSR

This product is a bidirectional voice coil motor driver IC with an integrated 10-bit DAC. The maximum output current is ±100 mA, with an operating voltage range of 2.3 V to 5 V. The device is controlled via an I2C serial interface with a maximum operating frequency of 1 MHz. The device address is 0x18 (7-bit address 0x0c), which can be changed at the factory. The product includes a VRC mode that allows programmable configuration of the output current waveform to minimize mechanical vibration and accommodate different types of voice coil motors. The product incorporates a power-on reset circuit and a power-down function. The reset circuit ensures proper operation of the digital circuitry during power-on. In power-down mode, supply current consumption is less than 1 μA. The product is suitable for autofocus applications in mobile cameras, digital cameras, camcorders, webcams, and action cameras. The product is available in a WLCSP 0.73 mm × 1.13 mm × 0.30 mm -6B package.
