Turnkey Answer Simplifies Charger Design with Embedded MCU, Quick-Charging Assist, and Fewer Exterior Parts.
Nexperia has unveiled a brand new sequence of USB Kind-C and USB Energy Supply (USB PD) controller ICs designed for quick, environment friendly charging throughout a large 18–140 W energy vary. With this launch, the corporate turns into the one semiconductor provider to supply each element required to construct high-performance USB charging adapters—streamlining growth and rushing time-to-market for shopper machine producers.
The important thing options are:
- Programmable Kind-C supply functionality (default, 1.5 A, 3 A)
- Built-in VCONN energy provide and change
- SOP’ communication for E-Marker cable detection
- Multi-protocol help: USB BC1.2 DCP, legacy & proprietary charging
- Large voltage vary: 3.3 V to 29.4 V
- 30 V tolerance on CC1/CC2 pins (short-to-VBUS safety)
- Low energy mode operation
This USB Kind-C Energy Supply controller permits versatile and environment friendly PD charging designs, supporting a variety of energy ranges from 18 W to 140 W—superb for contemporary adapters and chargers. It provides broad compatibility with high-performance cell charging protocols, guaranteeing sooner and extra dependable charging experiences. Security is enhanced by means of complete fault safety options, together with over-voltage, under-voltage, over-current, and thermal protections, together with safeguards in opposition to voltage shorts and line surges. The combination of key parts like drivers and discharge circuitry helps scale back general BOM value. Moreover, the controller helps sensible energy sharing in multi-port configurations and permits for customized logic and have extensions through its embedded MCU and programmable GPIOs, making it extremely adaptable for various USB energy functions.
The brand new single-port USB PD controllers—NEX52041 and NEX52080—characteristic built-in microcontrollers (MCUs) with 16 kB and 32 kB of MTP-ROM respectively. These embedded MCUs permit for versatile characteristic customization and firmware updates, guaranteeing long-term compliance with evolving USB PD requirements. Along with USB PD, each controllers help a number of D+/D− fast-charging protocols, enabling broad compatibility with legacy and present gadgets, from smartphones to laptops.
Packaged in compact 4 mm x 4 mm QFN-16 and QFN-24 kind components, the controllers additionally embody programmable GPIOs and I2C interfaces—superb for multi-port charger architectures the place environment friendly communication and sensible energy distribution are important.Whereas comparable controllers usually depend on additional exterior parts for cover, they combine as much as 30 V overvoltage tolerance straight on connector pins. This built-in resilience cuts BOM value and improves general robustness.
Engineered with a constant-voltage (CV) and constant-current (CC) management loop, these controllers help optocoupler-based suggestions programs and interoperate seamlessly with a spread of DC/DC and AC/DC converter topologies. When paired with the corporate’s full portfolio—together with AC/DC controllers, MOSFETs, GaN FETs, and ESD safety gadgets—designers can quickly create turnkey USB adapters for shopper charging functions.
