Maxim Integrated's MAX16056ATA31+T: Ultra-Low-Power Supervisor IC

The MAX16056ATA31+T is a highly efficient, ultra-low-power supervisor integrated circuit (IC) designed by Maxim Integrated, a renowned manufacturer of innovative analog and mixed-signal products. This compact, robust IC is engineered to monitor system voltages, ensuring that electronic devices operate reliably within their specified voltage ranges. It is an ideal solution for portable and battery-powered applications where power conservation is critical.

This supervisor IC is part of the MAX16056 series and comes in a tiny 8-pin TDFN (3mm x 3mm) package, which is perfect for space-constrained designs. With its wide operating voltage range from 1.575V to 5.5V, the MAX16056ATA31+T is versatile enough to accommodate a variety of power supply configurations. The device features a factory-trimmed reset threshold voltage of 3.1V, ensuring precise monitoring for 3.3V power rails.

One of the standout features of the MAX16056ATA31+T is its ultra-low quiescent current of just 1.6µA, which significantly extends battery life in portable applications. Additionally, the device offers a manual reset input, allowing for an external trigger to initiate a system reset, providing an extra layer of control and security.

The IC also includes a reset timeout period of 140ms (min), which holds the system in reset long enough to ensure a stable startup. Moreover, the MAX16056ATA31+T provides an active-low, open-drain reset output, which is compatible with a variety of microcontrollers and other digital devices.

Designed with reliability in mind, the MAX16056ATA31+T includes integrated features to protect against the detrimental effects of unpredictable system conditions. These include immunity to short voltage transients and the ability to ignore fast transients on VCC, which helps prevent false resets and ensures stable system operation.

In summary, the MAX16056ATA31+T from Maxim Integrated is a highly reliable, energy-efficient supervisory solution that is well-suited for applications where voltage monitoring and power conservation are paramount. Its small footprint, low power consumption, and robust feature set make it an excellent choice for designers looking to enhance the reliability and extend the battery life of their portable and compact electronic systems.
