Intelligent System Power Solution

The IDTP95020 is designed to provide maximum flexibility to system designers by providing full customization and programmability. It is a highly integrated single chip device that incorporates an embedded general purpose microcontroller, a high fidelity audio CODEC, full power management functionality, backlight driver, battery charger, touch screen controller, and real time clock, all of which make it an ideal solution for portable consumer devices, such as cellular phone handsets, portable gaming devices, digital media players, and portable navigational devices. The device compact footprint optimizes board area and reduces component count. The IDTP95020 embedded Microcontroller features 4kB factory-programmable ROM, or the I²C master can load a custom program from an external EEPROM module. The system power-on/power-off sequencing and general system housekeeping can be programmed in internal ROM or external EEPROM. The I²C slave can be used during operation to communicate with the host to accept commands and report status. The IDTP95020 operates from an adapter or USB power source to deliver power to the system load while charging the battery; up to 1.5A charging current. The input current is limited to the value set by the host for adapter source (up to 2A) or for USB source (100mA or 500mA). The switch-mode EnergyPathTM Battery Charger operates with a high efficiency buck regulator to transmit the power to the load with minimal loss. The IDTP95020 power management features along with the switching regulators and LDOs can provide power for most extremely complex hand-held devices. The device is offered in a small 132-ld 10x10x0.85mm QFN package and guaranteed to operate over the commercial temperature range 0°C to 70°C.
