Description
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 IC 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 IC 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.
Applications
Smart Phones
Portable Gaming Device
Digital Media Players
Handheld Computers
Portable Navigational Devices
