What are the key features of MAX6368LKA26+T?
- 2.63 V reset threshold with 280 ms reset delay for reliable microprocessor power-on and brownout detection
- Active-low push-pull reset output compatible with 0 V to 5.5 V supply rails without external pull-up resistors
- Integrated watchdog timer (WD) for autonomous system hang detection and recovery without external logic
- Battery backup switch support enabling seamless transition to backup supply during primary power loss
- Ultra-compact 8-pin SOT-23 package for space-critical embedded supervision circuits
What is MAX6368LKA26+T used for?
MAX6368LKA26+T is used in microprocessor-based embedded systems, industrial controllers, and communications equipment where reliable reset generation and watchdog supervision are required during power-up, brownout, and supply interruption events. The 2.63 V threshold and 280 ms delay make it suitable for 3.3 V systems that need margin against brief supply droops without nuisance resets. Its battery backup switch and watchdog functions also suit portable instruments and always-on IoT nodes that must recover autonomously from software lockups.

Frequently Asked Questions
At what supply voltage does MAX6368LKA26+T assert a reset signal, and how long does the reset stay active after power returns?
MAX6368LKA26+T asserts the active-low reset output when the supply voltage drops below the 2.63 V threshold and holds the reset active for a minimum 280 ms delay after the supply recovers above the threshold, ensuring the microprocessor clock and memory have fully stabilized before code execution resumes.
Does MAX6368LKA26+T require an external pull-up resistor on the reset output line?
No. MAX6368LKA26+T uses a push-pull active-low reset output, which can drive the reset line to a logic high level without an external pull-up resistor. This simplifies board design and ensures clean logic levels from 0 V to 5.5 V across the full supply range.
How does the integrated watchdog timer in MAX6368LKA26+T protect against software lockups in an embedded system?
The on-chip watchdog timer monitors for a periodic software kick signal; if the MCU firmware fails to toggle the watchdog input within the timeout window, MAX6368LKA26+T automatically drives the reset output low, forcing a full system restart without any external supervisor logic or additional ICs.
Is MAX6368LKA26+T suitable for a 3.3 V design that also needs battery backup supply switching?
Yes. MAX6368LKA26+T supports battery backup switching and operates over a 0 V to 5.5 V supply range, so it fits 3.3 V main-rail systems that need seamless switchover to a coin cell or backup battery when the primary supply falls below the 2.63 V reset threshold.
