The MAX6697 precision multichannel temperature sensor monitors its own temperature and the temperatures of up to six external diode-connected transistors. All temperature channels have programmable alert thresholds. Channels 1, 4, 5, and 6 also have programmable overtemperature 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 MAX6697 is specified for an operating temperature range of -40°C to +125°C and is available in 20-pin QSOP and 20-pin TSSOP packages.
The MAX6697 is a precision multichannel temperature monitor that measures its own temperature and up to six external diode‑connected transistors. It provides programmable alert thresholds for each channel and additional over‑temperature thresholds for channels 1, 4, 5, and 6. Two open‑drain outputs, ALERT and OVERT, indicate when thresholds are exceeded.
Communication is via a standard 2‑wire SMBus interface supporting write‑byte, read‑byte, send‑byte, and receive‑byte commands. The device operates from 3.0 V to 5.5 V, supports standby mode with sub‑15 µA current, and is available in 20‑pin QSOP and TSSOP packages.
| Operating Temperature Range | -40 °C to +125 °C |
|---|---|
| Supply Voltage (VCC) | 3.0 V to 5.5 V |
| Number of Temperature Channels | 7 (1 local + 6 remote) |
| Standby Supply Current | < 15 µA (typical 30 µA static) |
| Alert Outputs | Two open‑drain outputs (ALERT, OVERT) |
It uses a standard 2‑wire SMBus‑compatible serial interface for reading temperature data and programming thresholds.
The device provides one local temperature sensor and up to six remote diode‑connected channels, for a total of seven channels.
Yes, channels 1, 4, 5, and 6 have programmable over‑temperature thresholds that drive the OVERT open‑drain output.
In standby mode the supply current is reduced to less than 15 µA, while the SMBus interface remains active.
