Microchip TC54VN4002ECB713 Voltage Detector IC: Key Features and Applications

In the realm of electronic design, ensuring system stability and protecting circuitry from unpredictable power conditions is paramount. The Microchip TC54VN4002ECB713 stands as a critical component in achieving this goal. This voltage detector, or reset IC, is engineered to monitor voltage levels accurately and provide a clear output signal when the supply voltage falls below a predefined threshold. Its primary role is to hold a microcontroller or processor in a reset state during power-up, power-down, or brownout events, thereby preventing erratic operation and potential data corruption.

Key Features

The TC54VN4002ECB713 is distinguished by a set of robust features that make it a reliable choice for designers. Its most notable characteristic is its extremely low current consumption, typically drawing just 1.0 µA of supply current. This makes it exceptionally suitable for battery-powered and portable applications where power efficiency is a top priority.

It offers a precise detection threshold of 4.0V, which is factory-set with a high accuracy of ±2%. This precision ensures that the system reset is triggered at a consistent and reliable voltage point. The device features a push-pull output stage, which provides a strong, clean digital output signal without requiring an external pull-up resistor, simplifying circuit design and saving board space.

Furthermore, this IC is designed for high stability and low voltage drift over temperature variations, ensuring consistent performance across a wide operating range. Its small SOT-23 packaging is ideal for space-constrained PCB designs.

Primary Applications

The combination of low power and high accuracy opens the door to a wide array of applications. A primary use case is in portable and battery-operated devices such as digital multimeters, medical sensors, and handheld instruments. In these devices, the voltage detector ensures the microcontroller only operates when the battery voltage is sufficient for correct functionality.

It is also indispensable in consumer electronics like smart home devices, toys, and cameras, where it manages power-on reset sequences. Another critical application is in embedded systems and industrial control modules, where it safeguards against brownout conditions that could lead to system failures or unsafe states. Additionally, it finds use in automotive electronics for monitoring sub-system voltages, although specific automotive-grade qualifications should be verified for such use.

ICGOODFIND Summary

The Microchip TC54VN4002ECB713 is an ultra-low-power, high-accuracy voltage detector IC essential for ensuring system integrity in power-critical applications. Its minimal current draw, precise 4.0V threshold, and compact form factor make it an optimal solution for maintaining reliable operation in battery-powered portable devices, consumer electronics, and various embedded systems.
