Product Overview: Texas Instruments TPS2216DAPR

The TPS2216DAPR is a power distribution switch designed by Texas Instruments (TI) to enhance the management of power supply distribution in electronic systems. This sophisticated device is particularly well-suited for applications that require multiple power switches, such as notebook computers, docking stations, and other portable devices. With its compact PowerPAD™ package and advanced features, the TPS2216DAPR offers a reliable and efficient solution for controlling power to downstream peripherals.

Key Features

• Dual-Slot Power Interface: The TPS2216DAPR is designed to manage power for two slots, making it an ideal choice for systems with multiple peripherals requiring independent power control.
• Current Limiting: To protect against overcurrent conditions, the TPS2216DAPR features programmable current limiting. This ensures safe operation by preventing damage to the power switch and the connected devices.
• Thermal Shutdown Protection: The device includes a thermal shutdown feature that automatically turns off the power switch if it exceeds a certain temperature threshold, safeguarding the system from thermal damage.
• Under-Voltage Lockout (UVLO): The UVLO function ensures that the power switch operates only when the input voltage is within a specified range, preventing malfunctions due to insufficient supply voltage.
• Status Flag: An open-drain status flag output provides real-time feedback on the operational status of the switch, allowing for quick diagnostics and system monitoring.

Applications

The TPS2216DAPR's versatility makes it suitable for a wide range of applications. Its primary use is in systems that require controlled distribution and switching of power to various peripherals. Common applications include:

• Notebook computers and docking stations
• Desktop computers
• USB hubs and peripherals
• Hot-plug power supplies

Technical Specifications

The TPS2216DAPR operates with an input voltage range of 4.5V to 5.5V, which aligns with typical USB power specifications. The device is offered in a 30-pin HTSSOP (DAP) package that not only saves space but also improves thermal performance with TI's PowerPAD™ technology. It is also RoHS compliant and designed to meet the stringent requirements of industrial and commercial applications.

With its combination of dual-slot power management, integrated protection features, and status monitoring, the TPS2216DAPR from Texas Instruments represents a robust solution for sophisticated power distribution challenges in modern electronic devices.
