Description

General part information

TPS65090 Series

The TPS65090A device is a single-chip power management IC for portable applications consisting of a battery charger with power path management for a dual or triple Li-Ion or Li-Polymer cell battery pack. The charger can be directly connected to an external wall adapter. Three highly efficient step-down converters are targeted for providing a fixed 5-V system voltage, a fixed 3.3-V system voltage, and an adjustable voltage rail. The step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents. The step-down converters allow the use of small inductors and capacitors to achieve a small solution size. The TPS65090A also integrates two general-purpose always-on LDOs for powering circuit blocks which control the system while shut down. Each LDO operates with an input voltage range from 6 V to 17 V, allowing the LDOs to be supplied from the wall adapter or directly from the main battery pack.

Seven load switches are built into the device. These load switches can be used to control the power supply individually for certain circuit blocks in the application circuit. The current flowing through the load switches, as well as the output current of the step-down converters, the input current from the AC adapter and the charge current is monitored and can be read out using the digital interface.
