AS3701
Micro-PMIC
The AS3701 is a small compact PMU for small size and low power
applications.
AS3701 features one 500mA DCDC buck converter operating
from 1MHz up to 4MHz, two 200mA LDOs, two 40mA current
sinks and offers additional GPIO functions. Further, the device
contains an integrated linear battery charger with constant
current and constant voltage operation. The wide charging
current range going from 11mA up to 500mA and the integrated
battery temperature monitoring with selectable NTC beta
values make this device suitable for a great variety of
applications.
The single supply voltage may vary from 2.7V to 5.5V and all
functionalities of AS3701 can be controlled via the I²C interface.
