MAX6367PKA29+T MAX6367 Supervisor IC
The MAX6367PKA29+T is a high-precision, ultra-low-power microprocessor (µP) supervisory integrated circuit from Maxim Integrated (now Analog Devices), engineered to deliver robust power-supply monitoring, battery-backup switching, and memory write protection for embedded and battery-powered systems. Housed in a tiny 8-pin SOT-23 surface-mount package, this device features a factory-set 2.93V reset threshold, active-low open-drain reset output, and a dedicated battery-on (BON) indicator. It operates over a wide 0V to 5.5V supply range, with functional voltage down to 1.2V, and is fully specified for the industrial temperature range (-40°C to +85°C), making it ideal for mission-critical applications requiring stable, reliable system supervision under harsh conditions.
This supervisory IC integrates four core functions: precision voltage monitoring with 2.93V threshold, automatic reset signal generation during power-up, power-down, and brownout events, internal VCC-to-backup-battery switching for CMOS RAM/RTC data retention, and chip-enable gating for fast memory write protection (1.5ns propagation delay). Key specifications include an ultra-low 10μA quiescent current, 280ms reset timeout delay, active-low open-drain reset configuration, and a battery-on status output to signal backup mode activation. It supports seamless supply switching, maintains stable performance with degraded inputs, and is fully RoHS-compliant, offering a compact, fully integrated solution to replace discrete supervisory components.
