AW36413
Sep 2018 V1.5
High Efficiency, Dual 1.5A Flash LED Driver
FEATURES
GENERAL DESCRIPTION
Support Flash and Indicator 2in1 application
The AW36413 is a dual LED flash driver that
Support Dual Color Temperature Flash LED
Application
1.5A Total Allowed LED Current During Operation
(ILED1+ILED21.5A)
Flash11.35mA~1.5A128 levels
11.72mA/level
Torch2.55mA~372mA128 levels

Indicator0.02mA~372mA128*128 levels
0.02mA/level
Flash Timeout40ms~1.6s16 levels
Flash/Torch/Indicator/IR Mode
High Efficiency: 85%
Optimized Flash LED Current During Low Battery
Conditions (IVFM)
Hardware Strobe Enable (STROBE)
Hardware Torch Enable (TORCH/TEMP)
provides a high level of adjustability within a small
solution size. The AW36413 utilizes a 2MHz or
4MHz fixed-frequency synchronous boost
l
tia 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 (ILED1+ILED21.5A). The AW36413
provides three IVFM protection modes to prevent
system reset or shutdown under low battery
n condition.
e The AW36413 is controlled via an I2C-compatible
fid interface. The main features of the AW36413
include: flash/torch current, flash timeout duration,
IVFM, TX interrupt, and NTC thermistor monitor.
The AW36413 also provides hardware flash and
hardware torch pins (STROBE and TORCH/TEMP)
to control Flash/Torch events.

o 0.4mm PitchCSP-12 Package
Compatible with AW3643, AW3644, AW36414
C APPLICATION
The 2MHz or 4MHz switching frequency options,
overvoltage protection (OVP), and adjustable
current limit allow for the use of tiny, low-profile
inductors and 10-µF ceramic capacitors. The
device operates over a 40°C to +85°C ambient
temperature range.
The AW36413 is available in small 0.4mm pitch
1.626mm×1.332mm CSP-12 package.
