LM75BIMX-3+

LM75BIMX-3+ is a digital temperature sensor and thermal watchdog with a 2-wire interface. This temperature sensor includes a delta-sigma analogue-to-digital converter, and a digital overtemperature detector. The host can query the LM75 through its I²C interface to read the temperature at any time. The open-drain overtemperature output (OS) sinks current when the programmable temperature limit is exceeded. The OS output operates in either of two modes, comparator or interrupt. The host controls the temperature at which the alarm is asserted (TOS) and the hysteresis temperature below which the alarm condition is not valid (THYST). Also, the LM75’s TOS and THYST registers can be read by the host. It is used in applications such as thermal system management, thermal protection, test equipment, computers and office electronics.
