The TS3USB221RSER is a USB Type-C™ power delivery (PD) controller from Texas Instruments, designed to simplify power management in USB-C-enabled devices. This device supports USB PD 3.0, USB Type-C Rev 1.4, and Programmable Power Supply (PPS) standards, enabling efficient negotiation of power delivery between hosts and devices. It integrates a configurable current-limiting switch and voltage/current monitoring to ensure safe operation, making it ideal for applications requiring precise power control in compact designs.

Key Features

The TS3USB221RSER operates over a supply voltage range of 4.5V to 24V and supports output currents up to 5A, with programmable current limits for flexible power management. It features built-in protections such as overvoltage, overcurrent, and short-circuit detection, enhancing system reliability. The controller communicates via I2C for configuration and status monitoring, while its low quiescent current (1.5 µA in shutdown mode) extends battery life in portable devices. It supports PPS with ±1% voltage accuracy and operates over an extended temperature range (-40°C to +85°C), ensuring robust performance in harsh environments.

Applications

Primarily used in USB-C power adapters, laptop chargers, and smartphone accessories, the TS3USB221RSER is critical for applications requiring fast, safe, and adaptive power delivery. It is widely employed in IoT devices, industrial charging systems, and automotive infotainment systems where compact size and protocol compliance are essential. Its ability to handle high currents and voltage ranges also makes it suitable for robotics, drones, and medical equipment needing reliable power management.

Summary

The TS3USB221RSER combines USB PD protocol support, robust protection features, and low-power operation, making it a versatile solution for USB-C power delivery in consumer electronics, industrial, and automotive applications. Its compact design, precise control, and broad voltage/current capabilities address the demands of modern systems requiring efficient, safe, and adaptable power solutions. This controller is essential for engineers designing next-generation devices that leverage USB-C’s advanced power capabilities.
