Description
The A3904 is a voice coil motor (VCM) driver, with an
I
2
C-compatible serial interface. Designed for camera autofocus
and zoom applications, this high accuracy digital IC is provided
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.
Output current is programmed via the I
2
C interface, in 500 uA
increments, with clock rates up to 400 kHz. I
2
C inputs set the
internal D-to-A converter output voltage that is the reference
for linear current control via a MOSFET output sink transistor.
To conserve battery power, a logic low signal on the SLEEPZ
input disables the output MOSFET and reduces the supply
current to <0.5
渭A.
A3904 internal protection features include thermal shutdown
and undervoltage lockout. Logic input levels are independent
of the supply voltage. The operating temperature range is
鈥?0擄C to 85擄C.
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
nominal overall height) DFN package, with NiAuPd leadframe
plating and an exposed tab for enhanced thermal dissipation
(suffix EW).
