Texas Instruments TPS2HC120-Q1 Smart High-Side Switch

Introduction

The Texas Instruments TPS2HC120-Q1 is a sophisticated automotive dual-channel smart high-side switch designed to operate efficiently within 12V battery systems. With its advanced features and robust protection mechanisms, this component is ideal for various automotive applications, ensuring reliability and performance.

Part Description

The TPS2HC120-Q1 integrates an NMOS power FET and charge pump, providing a low on-resistance (R_ON) of just 120mΩ. This characteristic minimizes power dissipation while allowing the switch to handle output load currents of up to 2A when both channels are active, or 2.5A when a single channel is enabled. The device is equipped with multiple protection features, including thermal shutdown, output clamp, and current limit settings, which enhance system robustness during fault conditions such as short circuits. Additionally, it offers selectable current limits ranging from 0.25A to 5A, improving reliability and reducing inrush currents for large capacitive loads. The TPS2HC120-Q1 is housed in a compact 28-pin HVSSOP package, making it suitable for space-constrained applications.
