Bi-VCM Driver IC - DONGWOON
Description
DW9767
Bi-VCM Driver IC with 8Kb eFlash
DW9767 is designed for linear control of bi-directional voice coil motors(Bi-VCM).
DW9767 is a single 10-bit DAC with typical +/100mA output current sinking capability and has 8Kbyte eFlash memory.
This device features Smart Actuator Control (SACTM) mode which can minimize the mechanical vibration and achieve faster mechanical settling time.
DW9767 operates from a single 2.
3V to 3.
3V supply.
The internal DAC and the eFlash are controlled via an I2C serial interface that operates at clock rate up to 1MHz.
DW9767 offers Power Down (PD) mode with current consumption less than 1uA.
DW9767 has software protection feature, which enables to guard against inadvertent writes.
