GENERAL DESCRIPTION
The AW3643 is a dual LED flash driver that
provides a high level of adjustability within a small
solution size. The AW3643 utilizes a 2MHz or
4MHz fixed-frequency synchronous boost
converter to provide power to the dual 1.5A
constant current LED sources. The dual 128 levels
current sources provide the flexibility to adjust the
current of LED1 and LED2 in Flash/Torch/IR
modes. The total allowed LED Current during
operation is 1.5A (I
LED1
+I
LED2
1.5A). The AW3643
provides three IVFM protection modes to prevent
system reset or shutdown under low battery
condition.
The AW3643 is controlled via an I
2
C-compatible
interface. The main features of the AW3643
include: flash/torch current, flash timeout duration,
IVFM, TX interrupt, and NTC thermistor monitor.
The AW3643 also provides hardware flash and
hardware torch pins (STROBE and TORCH/TEMP)
to control Flash/Torch events.
The 2MHz or 4MHz switching frequency options,
overvoltage protection (OVP), and adjustable
current limit allow for the use of tiny, low-profile
inductors and 10F ceramic capacitors. The
device operates over a 40°C to +85°C ambient
temperature range.
The AW3643 is available in small 0.4mm pitch
1.626mm ×1.332mm CSP-12 package.
