The new P95020 power management IC from Integrated Device Technology is a system-on-chip device intended to be used in portable consumer products such as smartphones, portable navigation devices, mobile Internet devices and e-books.
According to IDT, the P95020 PMIC is the first of its kind to include a full set of system power regulation and management functions along with human interface subsystems, including audio and touch interfaces support. The embedded MCU is complemented by integrated peripheral subsystems including several switch-mode DC/DC converters and low-dropout voltage regulators, battery charge management, LED drivers, low-power stereo audio and voice codecs with mixer capability, a class D amplifier and headphone driver, a PLL for on-chip and external clock generation, and a touch screen controller. The MCU uses on-board system management resources, such as instrumentation SAR 12-bit ADC and a real-time clock, to provide optimum flexibility while reducing overall system power dissipation.
The embedded microcontroller of the IDT P95020 adds full programmability and flexibility to designs based on leading multimedia application processors. All functional blocks can be accessed over an I2C bus. The programmable voltage regulators meet the dynamic voltage adjustment requirements of application processors.
