MPQ4228
DESCRIPTION The MPQ4228 integrates a monolithic, stepdown switch-mode converter with a single USB current-limit switch, as well as a Type-C 5V @ 3A mode configuration channel for USB ports. It achieves 3A of output current across a wide input supply range, with excellent load and line regulation. The USB switch’s output is current-limited. The USB port supports Apple 3A Divider mode, DCP schemes for BC1.2, and 1.2V/1.2V mode. The USB port also supports USB Type-C 5V @ 3A DFP Mode and Type-A mode (CC1 = 97.6kΩ). Fault condition protections include hiccup current limiting, output over-voltage protection (OVP), DP/DM/CC1/CC2 short to battery protection, and thermal shutdown (TSD). The NTC input monitors the temperature of the external PCB, as well as other ponents. The MPQ4228 requires a minimal number of readily available, standard external ponents. The MPQ4228 is available in a QFN-22 (4mmx4mm) package. FEATURES - Supports Charging Only Type-C or Type-A Port - NTC Over-Temperature...
