FEATURES - 2 Qualified for Automotive Applications - AEC-Q100 Qualified With the Following Results - Device Temperature Grade 1: - 40°C to 125°C Ambient Operating Temperature Range - Device HBM ESD Classification Level H2 - Device CDM ESD Classification Level C4B - ±1°C Remote Diode Sensor - ±1°C Local Temperature Sensor - Programmable Non-Ideality Factor - Series Resistance Cancellation - Alert Function - Programmable Resolution: 9 to 12 Bits - Programmable Threshold Limits - Two-Wire/ SMBus™ Serial Interface - Minimum and Maximum Temperature Monitors - Multiple Interface Addresses - ALERT/THERM2 Pin Configuration - Diode Fault Detection APPLICATIONS - Automotive DESCRIPTION The TMP411-Q1 is a remote temperature sensor monitor with a built-in local temperature sensor. The remote temperature-sensor diode-connected transistors are typically low-cost, NPN- or PNP-type transistors or diodes that are an integral part of microcontrollers, microprocessors, or FPGAs. Remote accuracy is ±1°C for multiple IC manufacturers, with no calibration needed. The twowire serial interface accepts SMBus write byte, read byte, send byte, and receive byte mands to program the alarm thresholds and to read temperature data. Features that are included in the TMP411-Q1 are: series resistance cancellation, programmable nonideality factor, programmable resolution, programmable threshold limits, minimum and maximum temperature monitors, wide remote temperature measurement range (up to 150°C), diode fault detection, and temperature alert function. The TMP411-Q1 is available in an VSSOP-8 package.
