TSE2004GB2C0 Datasheet | IDT

Description The TSE2004GB2C0 digital temperature sensor es with several user-programmable registers to provide maximum flexibility for temperature-sensing applications. The userprogrammable registers specify critical, upper and lower temperature limits, as well as hysteresis settings. Both the limits and hysteresis values are used for municating temperature events from the chip to the system. This munication is done using the EVENT_n pin, which has an open-drain configuration. The user has the option of setting the EVENT_n pin polarity as either an active-low or active-high parator output for thermostat operation, or as a temperature event interrupt output for microprocessor-based systems. The sensor uses an industry standard 2-wire, I2C/SMBus serial interface, and allows up to eight devices to be controlled on the bus. The 4Kbit (512 bytes) Serial EEPROM memory in the part is organized as two pages of 256 bytes each, or 512 bytes of total memory. Each page is prised of two 128 byte blocks. The device can selectively lock the data in any or all of the four 128-byte blocks. Typical Applications - DIMM modules (DDR3, DDR4) - Servers, laptops, ultra-portables, PCs, etc. - Industrial temperature monitors - Hard disk drives and other PC peripherals Figure 1.
