Product Description

The MPQ4485 integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and charging port identification circuitry. The MPQ4485 achieves 6A of output current with excellent load and line regulation over a wide input supply range.
The output of the USB switch is current-limited. USB1 supports DCP schemes for battery charging specification (BC1.2), divider mode, 1.2V/1.2V mode, and USB Type-C 5V @ 3A DFP mode, eliminating the need for outside user interaction. USB2 supports DCP and CDP schemes.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
The MPQ4485 requires a minimal number of readily available, standard, external components and is available in a QFN-26 (5mmx5mm) package.

Kit details

The MPQ4485 integrates a monolithic step-down switch-mode converter with two USB current-limit switches and charging port identification circuit. It achieves 6A output current over a wide input-supply range with excellent load and line regulation.

The output of the USB switch is current limited. USB1 supports DCP scheme for Battery Charging specification (BC1.2), the Divider Mode, 1.2V/1.2V Mode and USB TYPE-C 5V@3A DFP Mode eliminating outside user interaction. USB2 supports DCP/CDP schemes.

Fault condition protection includes hiccup current limiting, output OVP, and thermal shutdown (TSD).
