PMIC for Freescale's i.MX 6SoloLite Application Processor
ROHM's BD71805MWV utilizes power supply technology cultivated for mobile applications to optimize circuit configuration for the i.MX 6SoloLite processor. The result is significantly reduced power consumption during both standby and normal operation, prolonging battery life considerably.In addition, an RTC (Real Time Clock) function that enables clock and calendar management without driving the main processor is built in, increased operating time, along with a li-ion battery charger featuring 30V input overvoltage protection that eliminates the need for an external IC. This reduces footprint by 20%, contributing to greater miniaturization.
