LM96011 Datasheet | National Semiconductor

Description The LM96011 is part of a hardware monitor system, prised of two parts the Super I/O (Master) and LM96011 (slave). The LM96011 will be controlled by the Master and report to the master temperature, and voltage measurements using a Sensor Path™ single-wire bus. The LM96011 measures the temperature of its own die as well as an external device such as a processor thermal diode or a diode connected transistor. The LM96011 can resolve temperatures up to 140˚C and down to -55˚C. Using Σ∆ ADC it measures Vccp, +2.5V, +3.3V, +5V and +12V analog input voltages with internal scaling resistors. - Internal local temperature zone - 0.5 ˚C resolution - Measures temperatures up to 140 ˚C n 14-lead TSSOP package Key Specifications ± 2 % (max) n Voltage Measurement Accuracy ± 3 ˚C (max) n Temperature Sensor Accuracy n Temperature Range: - LM96011 Junction Temperature 0 ˚C to +85 ˚C - Remote Tempemperature +25 ˚C to +125 ˚C n Power Supply Voltage +3.0 V to +3.6 V n Average Power Supply Current 0.5 m A (typ) n Round-robin Conversion of All Channels 91ms to 1460 ms Features n Sensor Path Bus Interface - 2 hardware programmable addresses n Voltage Monitoring - 9-bit Σ∆ ADC - Internal scaling resistors for all inputs - Monitors Vccp, +2.5 V, +3.3 V, +5 V and +12 V n Temperature Sensing - Remote diode temperature sensor zone Applications n Microprocessor based equipment (Motherboards, Video Cards, Base-stations, Routers, ATMs, Point of Sale, …) Typical Application ..
