Key Terms
usb type-ctechnical
A USB Type-C is a standardized, reversible connector and cable format used to transfer data, video and power between electronic devices. Think of it like a universal wall outlet for gadgets: when manufacturers adopt the same plug, products become easier to use and cheaper to make. For investors, Type-C adoption affects product compatibility, supply-chain costs, regulatory compliance and consumer demand, all of which can influence sales and margins.
power delivery (pd)technical
Power delivery (PD) is the network of equipment and services that moves electricity from generators to homes, businesses and industrial users, including transmission lines, substations and distribution poles. Investors care because the quality, capacity and costs of power delivery determine how reliably customers receive electricity, affect operating expenses and capital needs for utilities and grid operators, and shape revenue risks and regulatory approvals—think of it as the plumbing that must work for electricity to reach the tap.
dual-role power (drp)technical
Dual-role power occurs when a single person holds both a top executive role and a key board oversight role, giving them control over day-to-day operations and the group that supervises those operations. For investors this concentration of authority can speed decisions like a single pilot flying a small plane, but it also reduces independent checks and raises the risk of unchecked mistakes or conflicts of interest, which can affect company performance and shareholder value.
configuration channel (cc) pinstechnical
Configuration channel (CC) pins are the small contact lines in a modern connector that let two devices talk briefly to agree how they will work together — for example which way the cable is plugged in, how much power to send, and which special features to enable. Like a brief handshake or traffic director, CC pins determine compatibility, safety limits and performance, so they matter to investors because they affect product functionality, component choices, certification needs and downstream revenue from accessories and services.
request data objecttechnical
A request data object is the packet of information a system sends when asking another system or service for action or information, like a filled-out order form sent to a supplier. It bundles the specific details needed to process the request—such as identifiers, parameters and instructions—so the receiving system knows what to do. For investors, clear and accurate request data objects matter because they drive automated reporting, trade execution and regulatory filings; mistakes or gaps can cause delays, errors or compliance risks that affect operations and value.
i2c interfacetechnical
An i2c interface is a simple electronic wiring method that lets tiny computer chips inside a device talk to each other over just two wires: one for timing and one for data. Think of it as a two-lane road where many components take turns sending short messages. Investors care because i2c affects how easily components are added, how much devices cost, and how quickly manufacturers can update or scale products.
microcontroller unit (mcu)technical
A microcontroller unit (MCU) is a tiny, self-contained computer on a single chip that acts as the “brain” for electronic devices, handling tasks like reading sensors, controlling motors, and running simple programs. Investors care because MCUs are a fundamental component in countless products from cars to home gadgets; their cost, availability, power use and performance can influence a manufacturer’s production costs, product features and competitiveness, and therefore the company’s revenue and margins.
PLANO, Texas--(BUSINESS WIRE)--
Diodes Incorporated (Nasdaq: DIOD) today introduces the AP53781 and AP53782 28V USB Type-C® Power Delivery (PD) dual-role power (DRP) controllers designed for managing DC power requests and outputs in battery-powered portable devices. The controllers support the latest USB PD3.1 extended power range (EPR) standard, delivering up to 140W for charging as well as releasing power from the internal battery. USB Type-C connector-equipped devices (TCD) featuring these dual-role ports include power banks, power tools, e-bikes, and portable displays, which removes the need for users to carry around several adaptors or cables.
The AP53781 and AP53782 feature powerful firmware configurations to automatically negotiate with the PD3.1 compliance charger as a sink role or TCD as a source role. Both devices support dead battery mode when the system battery cannot power the controllers, where they will act in a sink role until an external power source is connected. The 34V tolerant configuration channel (CC) pins enable robust system protection from accidental shorts to the high-voltage VBUS power line.
The AP53781 has a preloaded power data object/request data object (PDO/RDO) menu for easily selecting between the source/sink roles. The source role PDO menu has eight profiles. The RDO menu offers eight fixed output voltage levels and eight different output current selections as a sink role. These multiple power profiles are set by external resistors, removing the need for an expensive microcontroller unit (MCU) and reducing design complexity.
The AP53782 includes an I2C interface that provides greater flexibility for more sophisticated designs. The device communicates with the host MCU to automatically determine a more flexible power profile for the sink or source roles, as well as other intelligent power-management functions.
The AP53781 is supplied in the small-footprint 3mm x 3mm W-QFN3030-16 (Type A1) package, and the AP53782 in the 4mm x 4mm W-QFN4040-24 (Type A1) package. Both operate across the -40°C to +125°C junction temperature range. The AP53781 and AP53782 are available at $0.57 and $0.59, respectively, in 1,000-piece quantities.
