Description

General part information

BD71847AMWV Series

BD71847AMWV integrates all power rails required by i.MX 8M Mini processors and system peripherals. In addition to integrate a sequencer compatible with power modes supported by i.MX 8M Mini processors, making it possible to significantly reduce the development time, decrease size, and simplify application design.The power supply circuit of the BD71847AMWV, designed specifically for the power supply system of the i.MX 8M Mini processor family, integrates an 6 buck converters, 6 LDOs, and control logic that allows it to supply power not only to the processor, but the required DDR memory as well – all from a single chip. A 1.8V/3.3V power switch for SDXC cards is also built in, along with a 32.768kHz crystal oscillator driver and multiple protection circuits such as output short-circuit, output over-voltage/current, and thermal shutdown.Buck conversion efficiency from 83 to 95% is achieved for 0.7V to 3.3V output, and the wide input voltage range from 2.7V to 5.5V supports a variety of power sources, from batteries to USB, making them ideal for i.MX 8M Mini applications.Furthermore, when single-sided mounting and Type-3 PCB is assumed, 42 fewer parts are needed compared with discrete solutions, reducing PCB area by up to 42%.
