MAX6699EE34+

MAX6699EE34+ is a 5-channel precision temperature monitor. It monitors its own temperature and the temperatures of up to four external diode-connected transistors. All temperature channels have programmable alert thresholds. Channels 1 and 4 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, active-low OVERT and active-low 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. Applications include desktop computers, notebook computers, workstations servers.

• Four thermal-diode inputs, local temperature sensor
• Temperature monitoring begins at POR for fail-safe system protection
• Active-low ALERT and active-low OVERT outputs for interrupts, throttling, and shutdown
• 2-wire SMBus interface
• Supply voltage range from 3 to 5.5V
• Temperature resolution is 11bits at channel 1 only, VCC=+3.3V and TA=+25°C
• Supply sensitivity of temperature accuracy is ±0.2°C/V typ at VCC=+3.3V and TA=+25°C
• Data hold time is 300ns minimum at fSCL=100kHz
• 16 QSOP package
• Temperature range from -40°C to +125°C
