LM96011

LM96011 Hardware Monitor with Thermal Diode Input and SensorPath™ Bus ADVANCE INFORMATION September 2003 LM96011 Hardware Monitor with Thermal Diode Input and SensorPath™ Bus General Description The LM96011 is part of a hardware monitor system, comprised 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 SensorPath™ 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 mA (typ) n Round-robin Conversion of All Channels 91ms to 1460 ms Features n SensorPath 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 20081803 SensorPath™ is a trademark of National Semiconductor Corporation © 2003 National Semiconductor Corporation DS200818 www.national.com LM96011 Hardware Monitor with Thermal Diode Input and SensorPath™ Bus Block Diagram 20081801 LIFE SUPPORT POLICY NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.
