MPQ4475-E
DESCRIPTION
The MPQ4475-E integrates a monolithic, stepdown, switch-mode converter with a single USB current-limit switch and charging port identification circuit. The MPQ4475-E achieves 2.5A of continuous output current with excellent load and line regulation over a wide input supply range.
The output of the USB switch is current-limited. The MPQ4475-E provides a USB-dedicated charging port (DCP), which supports battery charging specification 1.2 (BC1.2), divider mode, and 1.2V/1.2V mode without the need for outside user interaction. The output voltage has programmable line drop pensation.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
The MPQ4475-E requires a minimal number of readily available, standard, external ponents and is available in a QFN-25 (4mmx4mm) package.
