Diodes launches decoder IC compatible with Qualcomm QC 2.0 protocol for fast charging of mobile phones

21ics Diodes has introduced the decoder integrated circuit AP4370, which is used for fast charging of mobile phones, tablets and similar consumer products with Qualcomm system single chip equipped with Quick Charge (QC) technology.

Compatible with Qualcomm's high-voltage dedicated charging port QC 2.0 protocol, the AP4370 provides a highly integrated and low-cost solution to help designers design chargers and adapters that support QC charging. The new decoder provides a constant voltage or constant current control by changing the V1/V2 output of the controller voltage reference or voltage feedback divider resistor for different D+/D-signal combination decodings produced by portable devices. .

The AP4370 has an overvoltage discharge function. When QC 2.0 wiring devices require a lower output voltage, the device accelerates the output voltage drop during voltage conversion to protect the device. If the connection device is not compatible with QC 2.0, the decoder will automatically provide a 5V output configuration. The AP4370 offers a supply voltage range from 5V to 12V and an ultra-low quiescent current of only 90μA at 5V output voltage. This integrated circuit requires only a small number of external components, and also offers two small package options, SOT26 and TSOT26, which saves board space and material costs.

The new products are shipped in quantities of one thousand.
