Maxim Integrated MAX16021PTES+T Battery Backup Supervisor

The MAX16021PTES+T from Maxim Integrated is a sophisticated battery backup supervisor designed to enhance the reliability and extend the life of nonvolatile memory systems. This compact, lead-free device comes in a space-saving, 6-pin TDFN package, making it an ideal solution for applications where board space is at a premium.

Equipped with a wide operating voltage range of 1.8V to 5.5V, the MAX16021PTES+T is versatile enough to accommodate a variety of power systems. Its primary function is to automatically switch between main power and battery power during failure conditions, ensuring that critical data is preserved in nonvolatile memory components like SRAM, real-time clocks (RTCs), and microcontrollers (MCUs).

One of the standout features of this battery backup supervisor is its low quiescent current, which is essential for minimizing power consumption during battery backup mode. This allows for longer battery life, reducing the frequency of battery replacements and maintenance for end-users. Additionally, the device provides a manual reset input, allowing for system resets without the need to cycle power.

The MAX16021PTES+T also includes a debounced manual reset input, which can be used to initiate a system reset with an external pushbutton or logic signal. This feature adds an extra layer of control and safety, ensuring that systems can be quickly and reliably reset when necessary.

For added convenience, this battery backup supervisor comes with an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold. This ensures that the system has sufficient time to stabilize before resuming operation, thereby preventing potential errors during power-up sequences.

The device's robust design is further enhanced by its wide operating temperature range of -40°C to +85°C, making it suitable for use in harsh environments. Whether deployed in industrial controls, servers, or portable electronics, the MAX16021PTES+T offers a reliable solution for maintaining data integrity during power failures.

In summary, Maxim Integrated's MAX16021PTES+T is a high-performance battery backup supervisor that combines low power consumption, compact design, and advanced features to ensure uninterrupted operation and data preservation in a wide range of electronic systems.
