A3904  
Low Voltage Voice Coil Motor Driver  
Features and Benefits  
Fixed I2C logic thresholds  
8-bit D-to-A converter  
Description  
The A3904 is a voice coil motor (VCM) driver, with an  
I2C-compatibleserialinterface.Designedforcameraautofocus  
andzoomapplications,thishighaccuracydigitalICisprovided  
in small packages ideal for portable devices. Its operating  
voltage range is 2.4 to 5.5 V, and its maximum output current  
is 127 mA.  
500 μA resolution  
Low voltage I2C serial interface  
Low current-draw sleep mode  
2.4 to 5.5 V operation  
2 mm × 1.5 mm, 0.38 mm nominal overall height DFN  
1.1 mm×0.7 mm, 0.5 mm maximum overall height WLCSP Output current is programmed via the I2C interface, in 500 uA  
1.1 mm × 0.7 mm, 0.33 mm nominal overall height bare die increments, with clock rates up to 400 kHz. I2C inputs set the  
internal D-to-A converter output voltage that is the reference  
for linear current control via a MOSFEToutput sink transistor.  
To conserve battery power, a logic low signal on the SLEEPZ  
Packages:  
input disables the output MOSFET and reduces the supply  
current to <0.5 μA.  
A3904 internal protection features include thermal shutdown  
and undervoltage lockout. Logic input levels are independent  
of the supply voltage. The operating temperature range is  
–40°C to 85°C.  
1.5 mm × 2 mm DFN  
(EW package)  
1.1 mm × 0.7 mm WLCSP  
(CG package)  
The A3904 is available at three packaging levels: bare die on  
wafer (suffix CW); bumped wafer level chip scale package  
(WLCSP) (suffix CG); and complete thin profile (0.38 mm  
nominaloverallheight)DFNpackage,withNiAuPd leadframe  
plating and an exposed tab for enhanced thermal dissipation  
(suffix EW).
