Microchip Know-how has launched a Qi 2.0 dual-pad wi-fi energy transmitter reference design. Powered by a single dsPIC33 Digital Sign Controller (DSC), the Qi2 reference design affords environment friendly management for optimized efficiency. A key function of the brand new Qi2 customary, just lately launched by the Wi-fi Energy Consortium (WPC), is the introduction of a Magnetic Energy Profile (MPP) with assist for magnetic alignment between the transmitter and the receiver. The DSC’s versatile software program structure allows the assist of a mix of MPP and Prolonged Energy Profile (EPP) of Qi 2.0 with one controller.
Using the Qi2 reference design helps reduce buyer danger in certifying their ultimate product, which is required to cross via the Qi certification course of. Because it integrates a number of of Microchip’s automotive-qualified components, the dual-pad charger additionally meets automotive requirements for reliability and security. The automotive-grade {hardware} and software program answer allows simpler automotive integration with assist for Automotive Open System Structure (AUTOSAR) and AUTOSAR Microcontroller Abstraction Layer Structure (MCALs), useful security, and extra. An built-in CryptoAuthentication IC supplies safety to fulfill the stringent authentication requirement of Qi requirements.
As a part of the reference design, Microchip can ship design recordsdata and software program designed to create a simple design expertise and first-pass success. The design consists of the dsPIC33 DSC and a TA100/TA010 Belief Anchor safe storage subsystem provisioned by Microchip as a licensed Wi-fi Energy Consortium (WPC) Producer Certificates Authority. Moreover, the design additionally consists of Microchip’s ATA6563 CAN transceiver, MCP14700 gate drivers, and MCP16331 and MCP1755 regulators.
Key options embrace: Twin-pad transmitter supporting Qi 2.0; MPLA and Q-FOD; Thermal energy foldback and shutdown; Transmitter primarily based on fixed-frequency topology management to optimize EMI/EMC efficiency; Straightforward integration into automotive environments with CAN FD {hardware}/software program; dsPIC33 able to integrating Close to Subject Communication (NFC) for card detection/safety and communication; UART-USB communication and GUI for superior reporting/debugging of information packets; {Hardware} reconfigurable and able to supporting most transmitter topologies;
