The MAX6693 is a precision 7-channel temperature monitor with beta compensation, local temperature sensor, and 1.5°C remote temperature accuracy (+60°C to +100°C). Monitoring begins at POR for fail-safe system protection. The device also features ALERT and OVERT outputs, STBY input, and small, 20-pin TSSOP package.
The MAX6693 is a precision multichannel temperature monitor that measures its own temperature and up to six external diode‑connected transistors. It provides programmable alert and over‑temperature thresholds, two open‑drain status outputs (ALERT and OVERT), and a low‑power standby mode.
The device communicates via a 2‑wire SMBus‑compatible interface, operates from a 3.0 V‑3.6 V supply, and is offered in a 20‑pin TSSOP package. Key specifications include a –40 °C to +125 °C operating range, 7 channels (1 local + 6 remote), and beta‑compensation on channel 1 for improved accuracy.
