Product details

Single-channel supervisor with battery backup switchover

This part is designed for applications where a microcontroller or DSP needs a clean reset during power-up, power-down, or brownout conditions, and where battery backup switching is required to preserve SRAM or real-time clock data.

Because the reset output is active-low push-pull, the BOM saves a pull-up resistor compared to open-drain supervisors. The SOT-23-8 package fits tight layouts but still provides enough pins for the battery backup function — the backup battery connects to VBATT, and the supervisor switches the load to the backup when VCC drops.

For BOM planning, that removes the risk of a sudden discontinuation. RoHS3 compliance covers the latest EU directive requirements.

Frequently asked questions

Does MAX6367LKA44+T have a push-pull output?

Yes, the reset output is push-pull (totem pole), active low. No external pull-up resistor is needed.

What is the difference between MAX6367 and MAX6368?

The MAX6367 and MAX6368 are both battery backup supervisors with the same threshold and timeout options. The key difference is the reset output polarity: MAX6367 has an active-low reset, while MAX6368 has an active-high reset. Choose the polarity that matches your processor's reset input.

Can MAX6367LKA44+T be used with a lithium battery backup?

Yes, the battery backup circuit is designed to switch the load to a backup battery when the main supply drops. A lithium coin cell (e.g., CR2032) is a typical choice for preserving SRAM or RTC data during main power loss.
