Micro-PMIC
General Description
Figure 1: Added Value of Using AS3701
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.
