LTC1728ES5-2.5#TRPBF - Precision Micropower, Low Voltage Reset Monitor

The LTC1728ES5-2.5#TRPBF is a high-precision, micropower voltage monitor designed by Linear Technology, now part of Analog Devices. This compact component is specifically engineered to maintain system reliability by monitoring the supply voltage and asserting a reset if the voltage drops below a predetermined threshold. It is particularly suitable for low voltage, portable electronics where power efficiency and battery life are critical.

This voltage monitor comes in a small SOT-23 package, making it an ideal choice for space-constrained applications. The LTC1728ES5-2.5#TRPBF features a fixed threshold voltage of 2.5V, which is accurate to ±1.5% over the entire operating temperature range. This precise threshold ensures that the device can reliably detect under-voltage conditions and provide the necessary reset signal to microcontrollers and other digital devices to prevent improper operation.

The LTC1728ES5-2.5#TRPBF also boasts an extremely low quiescent current of only 10µA, which is beneficial for battery-powered devices as it contributes to minimal power consumption when in standby mode. The device's reset timeout period is internally set to approximately 200ms, providing a stable reset signal that prevents any false triggering due to transient conditions.

Furthermore, the LTC1728ES5-2.5#TRPBF offers several key features that enhance its performance. It has a wide operating temperature range from -40°C to +125°C, which allows it to function reliably in a variety of environmental conditions. The reset output is available in both active low and open-drain configurations, providing flexibility in interfacing with different types of logic circuits.

In summary, the LTC1728ES5-2.5#TRPBF from Linear Technology is a robust and precise voltage monitor that offers a combination of low power consumption, small package size, and high accuracy. It is an essential component for ensuring the stability and reliability of low voltage systems, particularly in portable and battery-operated applications.
