Extremely Built-in USB Decoder IC

The AP43776Q helps USB energy supply (PD) 3.1 customary energy vary (SPR) and programmable energy provide (PPS).

The AP43776Q USB decoder IC from Diodes is a extremely built-in, dual-channel, USB Sort-C, PD3.1 / PPS, BC 1.2 and QC protocol decoder. It helps USB energy supply (PD) 3.1 customary energy vary (SPR) and programmable energy provide (PPS). It helps legacy battery charging (BC) 1.2  in addition to Fast Cost QC5, quick charging protocols and is extremely optimized for multi-port automotive USB system charging techniques.

The AP43776Q encompasses a built-in microcontroller unit (MCU) with 12kB of one-time programmable (OTP) ROM, plus a multi-time programmable (MTP) ROM useful resource instrument. It options an I2C interface that permits inter-chip communication with DC-DC controllers and converters within the charging system. This simplifies the management loop and lowers general part prices. The system can assist the total vary of PPS APDO (augmented energy information object) from 3.3V to 21V with 20mV/step voltage decision and as much as 6A present with 50mA/step decision for energy administration. 

The AP43776Q additionally gives an embedded MCU and built-in ADC converters for voltage and temperature measurement, the place overtemperature safety (OTP) and different particular capabilities could be carried out by way of I2C pins and wealthy GPIO pins. Working at the side of two I2C-equipped Buck-Enhance controllers or converters which have PD3.1 PPS output circuitry, the AP43776Q serves because the I2C grasp and helps two unbiased PD3.1 PPS charging purposes with out utilizing extra output allow MOS chips for every PD3.1 output port.

The AP43776Q comes with a in-built firmware. It may possibly assist varied sensible power-management capabilities resembling a power-sharing scheme between two connected USB Sort-C PD gadgets, low-battery energy de-rating, thermal energy de-rating, LED gentle indication, and many others. Two AP43776Q gadgets can be interconnected by way of a UART (GPIO) pin to implement a sensible power-sharing scheme for all 4 linked USB Sort-C ports connected to a set energy supply
