This level of integration reduces the number of external components, lowers BOM cost, and simplifies the design of high-power USB Type-C charging ports. Typical applications include single-port and multi-port USB Type-C charging modules in vehicles.<\/p>\n<p>\nOperating from a 4V to 36V input, the device supports USB PD3.1 extended power range (EPR) and adjustable voltage supply (AVS) up to 28V, and standard power range (SPR) and programmable power supply (PPS) up to 21V. These capabilities enable USB Type-C charging ports delivering up to 140W.<\/p>\n<p>\nThe constant-frequency synchronous step-down controller with high drive strength, optimized dead\u2011time, and an elevated gate\u2011drive voltage enables efficient mid\u2011 to high\u2011power charging using external N-channel MOSFETs. This allows designers to choose MOSFETs that optimize efficiency and thermal performance. To further enhance converter power efficiency, the V<sub>IN<\/sub> DC power pass-through mode is supported. This architecture allows the high-side MOSFET to act as the V<sub>BUS<\/sub> switch, eliminating the need for an additional output switch and further reducing system cost.<\/p>\n<p>\nThe APK43070Q integrates an I2C interface with a controller\/target addressing scheme. This enables smart power sharing across up to eight USB Type-C ports through resistor selection without an external microcontroller (MCU). The result is a simpler system architecture for multi-port charging platforms.<\/p>\n<p>\nThe device includes several protection features to improve reliability. These include overvoltage, overcurrent, undervoltage, and overtemperature protection, plus connector moisture detection. The CC1\/CC2 and DP\/DN pins tolerate short-to-V<sub>BUS<\/sub> events up to 30V, helping protect the system from accidental faults.<\/p>\n<p>\nThe <a rel=\"nofollow\" href=\"https:\/\/cts.businesswire.com\/ct\/CT?id=smartlink&amp;url=https%3A%2F%2Fwww.diodes.com%2Fpart%2Fview%2FAPK43070Q&amp;esheet=54542138&amp;newsitemid=20260527583633&amp;lan=en-US&amp;anchor=APK43070Q&amp;index=2&amp;md5=dfa7ed77c2bf2dbfd7d08540808cea60\">APK43070Q<\/a> is available in the 4mm x 4mm W-QFN4040-24\/SWP (Type A1-B) package and priced at $0.80 in 1,000-piece quantities.
