TPS2553DBVT

The Texas Instruments TPS2553DBVT is a high-performance, low-power, single-supply I2C voltage supervisor with a reset output. It is designed to monitor the supply voltage of a system and provide a reset signal to the microcontroller or other logic when the supply voltage falls below a programmable threshold.

Description:

The TPS2553DBVT is a small, 6-pin SOT-23 package that includes an internal reference, an I2C interface, and a reset output. It has a very low power consumption of only 2.5µA, making it ideal for battery-powered applications.

Features:

• Wide operating supply voltage range: 1.5V to 5.5V
• Programmable reset threshold voltage from 1.5V to Vcc - 0.8V
• I2C interface for easy configuration and monitoring
• Active-low reset output
• Low power consumption: 2.5µA
• Small SOT-23 package

Applications:

The TPS2553DBVT is commonly used in a variety of applications where it is important to monitor the supply voltage and ensure that the system resets if the voltage falls below a certain level. Some common applications include:

1. Battery-powered systems: The TPS2553DBVT can be used to monitor the battery voltage and reset the system if the voltage falls too low, preventing damage to the battery and the system.
2. Power supply supervision: The TPS2553DBVT can be used to monitor the output voltage of a power supply and reset the system if the voltage falls below the specified threshold.
3. Microcontroller reset: The TPS2553DBVT can be used to provide a reset signal to a microcontroller or other logic when the supply voltage falls below the programmable threshold.
4. Industrial control systems: The TPS2553DBVT can be used in industrial control systems to monitor the supply voltage and reset the system if a power outage or other disturbance occurs.

Overall, the TPS2553DBVT is a versatile and reliable voltage supervisor that can be used in a wide range of applications where it is important to monitor the supply voltage and ensure that the system resets if the voltage falls below a certain level.
