MAX6658 - SMBus-Compatible Remote/Local Temperature Sensors

Description

The MAX6657/MAX6658/MAX6659 are precise, twochannel digital temperature sensors.

Each accurately measures the temperature of its own die and one remote PN junction, and reports the temperature in digital form on a 2-wire serial interface.

Features

  • o Dual Channel Measures Remote and Local Temperature o 11-Bit, +0.125°C Resolution o High Accuracy ±1°C (max) from +60°C to +100°C (Remote) o No Calibration Required o Programmable Under/Overtemperature Alarms o Programmable Conversion Rate (0.0625Hz to 16Hz) o SMBus/I2C-Compatible Interface o Two Alarm Outputs: ALERT and OVERT1 (MAX6657 and MAX6658) o Three Alarm Outputs: ALERT, OVERT1, and OVERT2 (MAX6659) o Compatible with 65nm Process Technology (Y Versions) Ordering Information PART MEASU.

19-2034; Rev 5; 10/10 MAX6657/MAX6658/MAX6659 ±1°C, SMBus-Compatible Remote/Local Temperature Sensors with Overtemperature Alarms General Description The MAX6657/MAX6658/MAX6659 are precise, twochannel digital temperature sensors. Each accurately measures the temperature of its own die and one remote PN junction, and reports the temperature in digital form on a 2-wire serial interface. The remote junction can be a diode-connected transistor like the low-cost NPN type 2N3904 or 2N3906 PNP type. The remote junction can also be a common-collector PNP, such as a substrate PNP of a microprocessor.
