... The MAX6604 also features an interrupt-output indica- tor for temperature-threshold monitoring. The threshold levels are programmable through the digital interface. The MAX6604 operates from -20°C to +125°C, and is available in JEDEC-standard 8-pin TSSOP and TDFN (MO-229-WCED-2) packages. Memory Modules ...

... A0, A1, and A2. See the Device Addressing section for details. The MAX6604 employs standard I using 16-bit registers: write word and read word. Write Serial Interface a word of data (16 bits) by first sending MAX6604’s I address (0011-A2-A1-A0-0), then sending the 8-bit 2 SMBus/I C command byte, followed by the first 8-bit data byte ...

... The thermal sensor continuously monitors the tempera- ture and records the temperature data at least eight times per second. Temperature data is latched internal the MAX6604 and can be read by software from the bus host at any time. Access to the temperature sensor is through the slave 0011-A2-A1-A0 ...

... In comparator mode, the EVENT output behaves like a window-comparator output that asserts when the tem- perature is outside the window. Reads/writes on the MAX6604’s registers do not affect the EVENT output in comparator mode. The EVENT signal remains asserted until the temperature goes inside the alarm window or the window thresholds are reprogrammed so that the current temperature is within the alarm window ...
