LM75BD,118

LM75BD,118 is a temperature-to-digital converter using an on-chip band gap temperature sensor and sigma-delta A-to-D conversion technique with an overtemperature detection output. The LM75B can be configured for different operation conditions. It can be set in normal mode to periodically monitor the ambient temperature, or in shutdown mode to minimize power consumption. The OS output operates in either of two selectable modes: OS comparator mode or OS interrupt mode. Its active state can be selected as either HIGH or LOW. The fault queue that defines the number of consecutive faults in order to activate the OS output is programmable as well as the set-point limits. This high-temperature resolution is particularly useful in applications of measuring precisely the thermal drift or runaway. Application includes system thermal management, personal computers, electronics equipment, and industrial controllers.
