TMP423 具有 N 因數(shù)和串聯(lián)電阻校正的 ±1°C 三路遠(yuǎn)程和本地溫度傳感器

描述

TMP421，TMP422和TMP423是帶有內(nèi)置本地溫度傳感器的遠(yuǎn)程溫度傳感器監(jiān)視器。遠(yuǎn)程溫度傳感器二極管連接的晶體管通常是低成本，NPN或PNP型晶體管或二極管，是微控制器，微處理器或FPGA的組成部分。

遠(yuǎn)程精度為±1°C適用于多個(gè)IC制造商，無需校準(zhǔn)。雙線串行接口接受SMBus寫字節(jié)，讀字節(jié)，發(fā)送字節(jié)和接收字節(jié)命令來配置器件。

TMP421，TMP422和TMP423包括串聯(lián)電阻消除，可編程非理想因子，遠(yuǎn)程溫度測量范圍廣（最高+ 150°C）和二極管故障檢測。

TMP421，TMP422和TMP423均采用SOT23-8封裝。 TMP421C還提供DSBGA（WCSP）封裝。
