7-Channel Precision Temperature Monitor With Beta Compensation

The MAX6693 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 ALERT, assert corre- sponding 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 tem- perature data and programming the alarm thresholds. The MAX6693 is specified for an operating temperature range of -40C to +125C and is available in a 20-pin TSSOP package. By Maxim Integrated Products
