TPS3705-33DRG4 Application Field and Working Principle

Power management integrated circuits (PMICs) are integrated circuits that are used to manage low-energy and medium-energy computer electronic systems. Supervisors are a type of PMIC specifically used to monitor and protect circuits from faults. They ensure the system operates safely and reliably. The TPS3705-33DRG4 is a single-channel supervisor and precision reset generator designed to protect against under-voltage or over-voltage, and overheating. This article will discuss the application field of the TPS3705-33DRG4, as well as its working principle.

Application Field

The TPS3705-33DRG4 is used everywhere circuits need protection and monitoring. It is used as an over-voltage/under-voltage protector (OV/UV) and a temperature monitor. It is used in industrial applications where circuits, such as motor controllers, need to be kept safe from faults, such as voltage or current surges, or sudden temperature changes. Furthermore, it can also be used in automotive applications, and applications in consumer electronics, such as monitors, TV sets, and more.

Working Principle

The TPS3705-33DRG4 works by monitoring the supply voltage and temperature. The voltage can be monitored using an adjustable threshold, which can be set to any value between 0.950V to 6.850V, or disabled. The temperature can be monitored using a transistor, which is adjustable from -40 to 125°C. When the voltage or temperature exceeds the adjustable threshold, the TPS3705-33DRG4 responds by generating a reset signal. This reset signal is used to protect the circuit from any faults or failures. Additionally, the TPS3705-33DRG4 also has an active low forced reset pin, which can be used to manually force a reset when necessary.

Conclusion

The TPS3705-33DRG4 is a single-channel supervisor and precision reset generator used to protect circuits against faults and failures, such as over-voltage/under-voltage and overheating. It is used in a variety of applications in both industrial and consumer electronics. It works by monitoring the supply voltage and temperature, and responding with a reset signal when the thresholds are exceeded. The active low forced reset pin can be used to manually force a reset when necessary.
