This document introduces the functions and characteristics of the MAX6683 system supervisor, including voltage monitoring, temperature monitoring, etc.
The MAX6683 is a system supervisor that monitors a local temperature sensor and up to three external supply voltages (1.8 V, 2.5 V, 5 V) as well as its own supply voltage. It communicates via an SMBus/I²C‑compatible 2‑wire serial interface and provides an ALERT output when programmed thresholds are exceeded.
The document includes electrical characteristics, timing diagrams, register maps, configuration options, and package information for the 10‑Pin pMAX (UMAX) device. It also describes recommended layout practices for accurate temperature sensing on a circuit board.
| Supply Voltage Range | 2.7 V to 5.5 V |
|---|---|
| Operating Temperature Range | -40 °C to +125 °C |
| Temperature Resolution | 0.125 °C per LSB (11‑bit mode) |
| Supply Current (typical) | 200 µA |
| Package | 10‑Pin pMAX (UMAX) package |
| Power‑On Reset Voltage | 2 V |
The device operates with a supply voltage between 2.7 V and 5.5 V.
In the default 11‑bit mode the resolution is 0.125 °C per LSB; in the reduced 9‑bit mode it is 0.5 °C per LSB.
It is supplied in a 10‑Pin pMAX (UMAX) package.
