Companion PMIC for Smartphone and Tablet
General Description
The MAX77829 is a high-performance companion PMIC
for latest 3G/4G smartphones and tablets. The PMIC
includes a single-input 2.0A switched-mode charger with
reverse-boost capability and adapter input protection
up to 22V (DC) for one-cell Lithium-Ion (Li+) battery, a
safeout LDO, and WLED backlight driver supporting up to
25mA/string, 35V output voltage. It also features a dual-
channel 1.5A (combined, 750mA/CH) Flash LED driver
(with Torch Mode included).
The typical 4MHz switched-mode battery charger with
two integrated switches, providing the smallest L/C size,
lowest heat and fastest programmable battery-charging
current, is ideally suited for portable devices such as
headsets and ultra-portable media players. The char-
ger features single input, which works for adapter/USB
type inputs. All the MAX77829 blocks connecting to the
adapter/USB pin are protected from input overvoltage
events. The DC pin is rated to 22V absolute maximum.
The USB-OTG output provides true-load disconnect and
is protected by an adjustable output current limit (default
900mA, other current limit is also available with different
factory setting up to 900mA).
The battery charger drives an external p-channel MOSFET
as power-path switch, and its I2C-programmable settings
can accommodate a wide range of battery sizes and
system loads. When configured in reverse boost mode,
the MAX77829 requires no additional inductor to power
USB OTG accessories and/or provide illumination to the
Flash LED.
The switching charger implements a special CC, CV,
and die temperature regulation algorithm; the patented
MaxFlash prevents overloading a weak battery, further
extending battery life.
The MAX77829 features an I2C 2.0-compatible serial
interface consisting of a bidirectional serial data line
(SDA) and a serial clock line (SCL).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
