The TPS2120YFPR is a high-side load switch from Texas Instruments, designed for efficient power management in portable and battery-operated devices requiring robust protection and precise current control. This device supports an input voltage range of 2.7V to 5.5V and delivers a maximum load current of 2A. It integrates overcurrent, overvoltage, and short-circuit protection to safeguard connected circuits, while its ultra-low on-resistance (40 mΩ) minimizes power loss. Housed in a compact WSON-8 package (2.9 mm × 2.1 mm), it enables space-saving designs in compact electronics.

Key Features

The TPS2120YFPR features programmable current-limit thresholds (0.5A to 2A) for customized protection, along with an enable pin for remote control and a fault indication output for system monitoring. Its soft-start function reduces inrush current, and it supports automatic retry or latched-off modes during fault conditions. The device operates over an extended temperature range (-40°C to +85°C) and offers low quiescent current (1 µA in off mode), making it ideal for battery-powered applications. It also includes thermal shutdown and reverse-voltage protection, ensuring reliability in harsh environments.

Applications

Primarily used in consumer electronics such as smartphones, tablets, and wearable devices, the TPS2120YFPR is critical for protecting sensors, actuators, and peripheral circuits from overloads or shorts. It is widely employed in industrial IoT devices, automotive infotainment systems, and medical equipment requiring reliable power switching. Its compact size and efficient operation also suit drones, robotics, and battery management systems where space and power consumption are critical design constraints.

Summary

The TPS2120YFPR combines high efficiency, comprehensive protection features, and compact form factor, making it a versatile solution for power delivery in portable and embedded systems. Its programmable current limits, low on-resistance, and robust fault management cater to applications demanding reliable, space-efficient power control in battery-operated or high-interference environments. This load switch is essential for engineers prioritizing both performance and reliability in consumer, industrial, and automotive electronics.
