Watchdog supervisor with 2.19 V threshold and 1.12 s timeout
The MAX6814XK+T is a single-channel watchdog circuit from Analog Devices, monitoring a single voltage rail with a 2.19 V threshold. The reset timeout is a minimum of 1.12 seconds, giving the system microcontroller a defined window to strobe the watchdog input before a system reset is triggered. This prevents the processor from locking up silently in unattended or safety-critical equipment.
Package and temperature grade for embedded use
Housed in a 5-lead SC-70-5 (SOT-353) package, the MAX6814XK+T occupies minimal board area and is suited for space-constrained designs such as portable instruments, sensor nodes, or control modules. The surface-mount footprint is standard for this package family.
