                      Product Overview

                      MAX6581TG9A+ is a precision multichannel temperature sensor that monitors its own temperature and the temperatures of up to seven external diode-connected transistors. All temperature channels have programmable alert and overtemperature thresholds. When the measured temperature of a channel crosses the respective threshold, a status bit is set in one of the status registers. Two open-drain alarm outputs (ALERT and OVERT) assert correspond to these bits in the status register(s). Resistance cancellation is available for all channels and compensates for high series resistance in circuit-board traces and thermal diodes. The 2-wire serial interface accepts SMBus protocols (write byte, read byte, send byte, and receive byte) for reading the temperature data and programming the alarm thresholds. It is used in applications such as desktop computers, notebook computers, workstations, servers, and data communications.

                      • Eight channels to measure seven remote and one local temperature
                      • Programmable under temperature/overtemperature alerts
                      • SMBus/I²C-compatible interface, resistance cancellation on all remote channels
                      • Two open-drain alarm outputs (active-low ALERT and active-low OVERT)
                      • Standby supply current is 4μA typical at (VCC = +3.0V to +3.6V, TA = -40°C to +125°C)
                      • Operating current is 500µA typical at (VCC = +3.0V to +3.6V, TA = -40°C to +125°C)
                      • Serial-clock frequency is 400KHz maximum at (VCC = +3.0V to +3.6V, TA = -40°C to +125°C)
                      • Pulse width of spike suppressed is 37ms typical at (VCC = +3.0V to +3.6V, TA = -40°C to +125°C)
                      • Operating temperature range from -40°C to +125°C
                      • 24-pin TQFN-EP package
