TPS26400RHFR

The TPS26400RHFR is a precision voltage supervisor circuit manufactured by Texas. It plays a critical role in monitoring voltage levels in power supplies and providing accurate reset signals to microcontrollers, processors, or other digital devices. This ensures reliable system operation during power-up, power-down, and fault conditions. With its precise voltage monitoring, adjustable threshold levels, and robust features, the TPS26400RHFR is widely used in various embedded systems, industrial equipment, and power management applications.

Key Features:

• Voltage Monitoring: Continuously monitors the input voltage level and generates a reset signal when it falls below or rises above a predefined threshold, ensuring proper system initialization and operation.

• Adjustable Reset Threshold: Allows users to adjust the reset threshold voltage via an external resistor, enabling customization to suit specific system requirements and voltage tolerances.

• Programmable Reset Delay: Features a programmable reset delay time, allowing designers to configure the duration of the reset pulse after the input voltage crosses the threshold, ensuring sufficient stabilization before system operation resumes.

• Manual Reset Input: Includes a manual reset input pin that allows for an external manual reset signal to override the internal reset function, providing flexibility in system debugging, testing, and fault recovery.

• Low Quiescent Current: Minimizes power consumption during normal operation, making it suitable for battery-powered and energy-efficient applications where power efficiency is critical.
