The MAX6698 precision multichannel temperature sensor monitors its own temperature, the temperatures of three external diode-connected transistors, and the temperatures of three thermistors. All temperature channels have programmable alert thresholds. Channels 1, 4, 5, and 6 also have programmable over-temperature thresholds. When the measured temperature of a channel exceeds the respective threshold, a status bit is set in one of the status registers. Two open-drain outputs, OVERT and ALERT, assert corresponding to these bits in the status register. The 2-wire serial interface supports the standard system management bus (SMBus™) protocols: write byte, read byte, send byte, and receive byte for reading the temperature data and programming the alarm thresholds. The MAX6698 is specified for an operating temperature range of -40°C to +125°C and is available in 16-pin QSOP and 16-pin TSSOP packages.
The MAX6698 precision multichannel temperature sensor monitors its own temperature, three external diode‑connected transistors, and three thermistors. All channels have programmable alert thresholds, and channels 1, 4, 5, and 6 also support programmable over‑temperature thresholds. The device communicates via a 2‑wire SMBus‑compatible serial interface and provides two open‑drain outputs (OVERT and ALERT) for interrupt or shutdown signaling.
The sensor operates from –40 °C to +125 °C and is available in 16‑pin QSOP and TSSOP packages. It features low standby current (less than 15 µA) and supports standard SMBus protocols for reading temperature data and programming alarm thresholds. Detailed electrical characteristics, pin descriptions, and timing diagrams are provided for system integration. This manual is written in Chinese.
| Operating Temperature Range | -40°C to +125°C |
|---|---|
| Supply Voltage (VCC) | 3.0 V to 5.5 V |
| Standby Supply Current | 30 µA (typical) |
| Alert/OVERT Outputs | Open‑drain |
It uses a 2‑wire serial interface that supports standard SMBus™ protocols for reading temperature data and programming alarm thresholds.
Two open‑drain outputs, OVERT and ALERT, assert when programmed temperature thresholds are exceeded.
In standby mode the supply current is reduced to less than 15 µA.
