Introduction to TPS22920YZPR

The TPS22920YZPR is a Power Management Integrated Circuit (PMIC) that allows designers to easily implement a power distribution switch, load driver, and over-temperature protection in their application.

Application Field and Working Principle of the TPS22920YZPR

The TPS22920YZPR is ideal for a wide range of applications, including general-purpose power distribution, control and load driving. It is designed to switch multiple power rails on and off, while protecting them against over-voltage, under-voltage and over-temperature conditions.

Power Distribution Switches

The TPS22920YZPR includes two independent power distribution switches, capable of controlling two power rails or two power-on/off signals. It provides low on-resistance and up to 5A of current (depending on the configuration option). The device also features two extra outputs for additional power control and sense, plus programmable over-temperature protection.

Load Drivers

The TPS22920YZPR load drivers take the load current requirement into consideration when controlling the load power. It can handle up to 5A of load current, with board level thermal management solutions available to increase this current handling capacity. The drivers are also designed to properly terminate cables with no additional hardware.

Over-temperature Protection

The TPS22920YZPR also offers over-temperature protection in the form of a digital temperature sensor. This sensor is capable of monitoring the temperature and can shut down if it detects a temperature exceeding the set threshold. The device can be used in combination with a thermistor or thermocouple for added accuracy.

Conclusion

The TPS22920YZPR is a versatile PMIC ideal for power distribution switch, load driver, and over-temperature protection applications. Its low on-resistance and high current handing capacity make it ideal for use in a variety of applications. The over-temperature protection sensor ensures that the device shuts down when dangerous temperatures are detected, protecting the application from damage.
