MPQ4228-Q
DESCRIPTION
The MPQ4228-Q integrates a monolithic, stepdown, switch-mode converter with a single USB current-limit switch and Type-C 5V @ 3A mode configuration channel for USB port applications. It achieves 3A of output current across a wide input supply range, with excellent load and line regulation.
The output of the USB switch is current-limited. The USB port supports Quick Charge 3.0 (QC3.0) mode. It is backwards patible with DCP schemes for battery charging specification (BC1.2), Apple 3A divider mode, and 1.2V/1.2V mode, without requiring outside user interaction. The USB port also supports USB Type-C 5V @ 3A DFP mode.
Fault protections include hiccup current limiting, output over-voltage protection (OVP), DP/DM/CC1/CC2 short to battery, and thermal shutdown (TSD).
The negative temperature coefficient (NTC) input monitors the external PCB or other ponents’ temperature(s).
The MPQ4228-Q requires a minimal number of readily available, standard external ponents, and is available in...
