说明
The AW8601A is a bidirectional voice coil motor driver chip, which contains a 10-bit DAC. The maximum output current is ±200mA. AW8601A operating voltage from 2.3V to 5V.
The AW8601A is controlled through the I2C serial interface, and its operating frequency can reach up to 1MHz. The device address of the chip is 7-bit 0x0c, and which can be changed by the factory.
The AW8601A contains VRC mode, which allows programmable configuration of output current waveform to minimize mechanical vibration and can be suitable for different types of voice coil motors.
The AW8601A contains power on reset circuit and power off function. The reset circuit ensures that the digital circuit works well when supply power up. In power down mode, the supply current consumption less than 1μA.
The AW8601A can be used for auto focus applications in mobile cameras, digital still cameras, camcorders, web cameras and action cameras.
The AW8601A is available in a WLCSP 0.73mm x 1.13mm x 0.30mm -6B package.
