1 / 53 page  2014 Microchip Technology Inc. DS20005275A-page 1 Data Sheet PRODUCT FEATURES EMC1428 1°C Multiple Temperature Sensor with HW Thermal Shutdown & Hottest of Thermal Zones General Description The EMC1428 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to CPU diodes requiring the BJT or transistor model) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. Additionally, the EMC1428 provides a hardware programmable system shutdown feature that is programmed at part power-up via a single TRIP_SET voltage channel that cannot be masked or corrupted through the SMBus. The EMC1428 provides ±1° accuracy for external diode temperatures and ±2°C accuracy for the internal diode temperature. The device monitors up to eight temperature channels (up to seven external and one internal). Applications Notebook Computers Desktop Computers Industrial Embedded Applications Features Hardware Thermal Shutdown — triggers dedicated SYS_SHDN pin — hardware configured range 65°C to 127°C in 1°C steps — cannot be disabled or modified by software Supports diodes requiring the BJT or transistor model Resistance Error Correction (up to 100 Ohms) Up to seven External Temperature Monitors — ±1°C Accuracy (60°C < TDIODE < 100°C) — 0.125°C Resolution — Supports up to 2.2nF filter capacitor — Anti-parallel diodes for extra diode support and compact design Internal Temperature Monitor — ±2°C accuracy 3.3V Supply Voltage Available in a 16-pin 4mm x 4mm QFN RoHS Compliant package Programmable temperature limits for ALERT Block Diagram |
