AAT3607 Part Attribute
- Description The AAT3607 is a member of the Skyworks Total PowerManagement IC (TPMIC™) product family that functions as ahighly integrated power management unit (PMU) for MP3/MP4players and other handheld applications. It integrates a single-cellLithium Ion/Polymer battery dynamic charger module poweredfrom an AC/DC adapter or USB port, three 120° phase shiftedsynchronous 1.6 MHz DC-DC step-down converters and two LDOsfor the system. The typical input power source for the AAT3607 is a single-cellLi-ion battery. The charger can be powered from either a currentlimitedUSB port or an AC/DC adapter, with charge currentprogrammed by two separate external resistors and selected by alogic input pin. With the device’s dynamic charging feature, asystem connected to the AAT3607 can draw power from thepower supply without a battery, or charge the battery with thepower left over from the system. If the power supply has limitedcurrent capability, the system draws power from both the limitedpower supply source and the battery. The battery charger is a complete constant current/constantvoltage linear charger. It offers an integrated pass device, reverseblocking protection, high accuracy current and voltage regulation,charge status, and charge termination. The charging current isprogrammable by means of an external resistor up to 1 A. The AAT3607 also includes over-voltage input protection (OVP),under-voltage lockout (UVLO), and over-temperature protection(OTP) to protect the PMU under fault conditions. The three integrated step-down converters operate undersynchronous PWM control with a 1.6 MHz switching frequencyand internal compensation, decreasing both size and quantity ofexternal components. The phase shift feature allows ripplecancellation between the three converters when all are runningwith nominal load. The AAT3607 is available in a thermally enhanced 28-pin 4 mm 4 mm TQFN package with exposed pad.
