AS3715

Dual Power Path PMIC

The AS3715 is a compact System PMU supporting two Li-Ion batteries and up to 14 power rails.

The device offers advanced power management functions. All necessary ICs and peripherals in a battery powered mobile device are supplied by the AS3715. It features 3 DCDC buck converters, one DCDC buck controller, a 5V HDMI booster, a HV backlight boost controller with 3 current sinks as well as 8 LDOs 2 low noise . The different regulated supply voltages are programmable via the serial control interface. 3-4MHz operation with 0.47uH coils is reducing cost and PCB space.

AS3715 contains a linear or switch mode Li-Ion battery charger with constant current and constant voltage operation. The maximum charging current is 1.5A. An internal battery switch and an optional external switch are separating the battery during charging or whenever an external power supply is present. In addition a second external battery path can be controlled. With these switches it is also possible to operate with no or deeply discharged batteries.

A dual USB input current limiter can be used to control the current taken form the USB supplies or charger inputs. Additional features are a 30V OV protection and JEITA compliant battery temperature supervision with selectable NTC beta values.

The single supply voltage may vary from 2.7V to 5.5V.
Ordering Information and Content Guide appear at end of datasheet.
