Introduction

The TPS22960RSER is a miniature integrated low-side power switch with various system options, ideal for applications such as smart home, industrial automation and lighting. It enables high frequency, high efficiency, and low-profile designs, especially for loads or switching up to 38V, 15A. It belongs to a family of integrated power switches that is widely used, especially in monitoring and controlling applications. It is classified in the PMIC category: Power Distribution Switches, Load Drivers.

Application Field

The TPS22960RSER is widely applied in low-side switch and load management. As it features over-temperature protection, short-circuit protection and an adjustable current limit, it is especially appropriate for motor, solenoid, heating, resistive-load applications, etc. In addition, its various system options, including fall-time select, adjustable soft-start, adjustable current limit and adjustable dead-time, make it even more attractive. Moreover, its inherent user-selectable slew rate and shoot-through protection are two of the many exciting features to consider. It is also compatible and easy to integrate with a wide range of voltage sources. All these features make this power switch ideal for many automotive, consumer and industrial applications.

Working Principle

The TPS22960RSER works by providing an efficient load-switching architecture, intended to allow smooth switch toggling between the load and the drive. This power switch is capable of controlling many different types of loads, such as motors, solenoids, heating elements, resistive loads, and more. Specifically, the micro-controller connected to the IC actively controls the on/off switching by providing a logic signal to the signal pin (EN). When the logic state is high, the output gate signal of the MOSFET is high, turning the device on. When the logic signal is low, the gate is pulled down into a low-resistance state, turning the device off. With user-selectable slew rate and shoot-through protection, the device serves a wide range of load switch requirements, such as resistive load, DC motors and solenoid, with enhanced detect-to-act control features. Furthermore, other features such as adjustable soft-start, adjustable current limit and adjustable dead-time, make forth a remarkable power performance and make the device much more complete and reliable for a wide range of applications.

Conclusion

The TPS22960RSER offers a comprehensive embedded power solution for many low-side switch and load management applications. It offers floating gate MOSFETs, including over-temperature protection, current limitation protection and shoot-through protection. Moreover, various system options make it perfect for many automotive, consumer and industrial applications, such as blasting audio, MEMS, motors, solenoids, heating elements, resistive loads and more.
