MAX6697EP99+T Board Mount Temperature Sensor IC 7-Channel Precision Temperature Monitor

MAX6697EP99+T Board Mount Temperature Sensors 7-Channel Precision

Temperature Monitor

Description
The MAX6697 precision multichannel temperature sen-
sor monitors its own temperature and the temperatures
of up to six external diode-connected transistors. All
temperature channels have programmable alert thresh-
olds. Channels 1, 4, 5, and 6 also have programmable
overtemperature thresholds. When the measured tem-
perature of a channel exceeds the respective thresh-
old, a status bit is set in one of the status registers. Two
open-drain outputs, OVERT and AL ERT, assert corre-
sponding to these bits in the status register.
The 2-wire serial interface supports the standard system
management bus (SMBusTM) protocols: write byte, read
byte, send byte, and receive byte for reading the tem-
perature 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.

Key Features of the MAX6697EP99+T:

• 7-channel temperature monitoring: The MAX6697EP99+T can monitor its own temperature and up to six
• external diode-connected transistors [1].
• Programmable alert thresholds: Each temperature channel has programmable alert thresholds, allowing
• for customized temperature monitoring [1].
• Overtemperature thresholds: Channels 4, 5, and 6 also have programmable overtemperature thresholds,
• providing additional monitoring capabilities [1].
• Status registers and outputs: When the measured temperature of a channel exceeds the respective
• threshold, a status bit is set in one of the status registers. The MAX6697EP99+T features two open-drain
• outputs, OVERT and ALERT, which assert corresponding to these bits in the status register [1].
• 2-wire serial interface: The sensor supports the standard system management bus (SMBus) protocols,
• including write byte, read byte, send byte, and receive byte. This interface allows for easy temperature
• data reading and programming of alarm thresholds [1].
• FailSafe system protection: Temperature monitoring begins at power-on reset (POR), ensuring system
• protection [1].
• Small package options: The MAX6697EP99+T is available in 20-pin QSOP and 20-pin TSSOP packages [1].

Specifications:

• Temperature range: The MAX6697EP99+T is specified for an operating temperature range up to +125°C [1].
• Supply voltage: VCC can range from 0V to +6V [1].
• Power dissipation: The continuous power dissipation varies depending on the package type and temperature.
• For example, the 20-pin QSOP package has a power dissipation of 727.3mW at +70°C (derated by 9.1mW/°C
• above +70°C) [1].
• ESD protection: The sensor provides ESD protection of ±2000V for all pins, based on the Human Body Model [1].
