Overview

ADT7461 は、PC や温度管理システムでの使用を目的としたデュアルチャネル・デジタル温度計であり、低温/高温アラームでもあります。ADM1032 のピン互換とレジスタ互換があります。ADT7461 には、直列抵抗キャンセル機能 (温度モニタ・ダイオードと直列になっている最大 3 kΩ (標準) の抵抗が温度結果によって自動的にキャンセルされることで、ノイズ・フィルタリングが可能)、構成可能な~ALERT 出力、切替可能な拡張温度測定範囲の 3 つの機能が追加されています。

  • Thermal Management

  • Notebook and Desktop Computers
  • Game Consoles
  • RFID Readers
  • DSL Line Cards

  • On-chip and Remote Temperature Sensor
  • 0.25°C Resolution/1°C Accuracy on Remote Channel
  • 1°C Resolution/3°C Accuracy on Local Channel
  • Automatically Cancels up to 3 kΩ (typical) of Resistance in Series with Remote Diode to Allow Noise Filtering
  • 2-wire SMBus Serial Interface with SMBus Alert Support
  • Programmable Over/Under Temperature Limits
  • Up to Two Over Temperature Fail-safe THERM Outputs
  • 170 µA Operating Current, 5.5 µA Standby Current

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
