帶看門(mén)狗計(jì)時(shí)器的電壓監(jiān)控器

TPS382x 系列監(jiān)控器主要為 DSP 和基于處理器的系統(tǒng)提供電路初始化和計(jì)時(shí)監(jiān)測(cè)等功能。上電期間，RESET 會(huì)在電源電壓 VDD 超出 1.1V 時(shí)置為有效。因此只要滿(mǎn)足以下條件，電源電壓監(jiān)控器就會(huì)監(jiān)測(cè) VDD 并將 RESET 保持為低電平有效：VDD 保持在閾值電壓 VIT? 以下。內(nèi)部計(jì)時(shí)器將會(huì)延遲輸出恢復(fù)至無(wú)效狀態(tài)（高電平）的時(shí)間，以確保系統(tǒng)正常復(fù)位。延遲時(shí)間 td 始于 VDD 上升至高于閾值電壓 (VIT? + VHYS)。當(dāng)電源電壓降到閾值電壓 VIT? 以下時(shí)，輸出再次變?yōu)橛行顟B(tài)（低電平）。無(wú)需外部組件。該系列中的所有器件均具有一個(gè)通過(guò)內(nèi)部分壓器設(shè)定的固定檢測(cè)閾值電壓 ? 具有固定延遲時(shí)間 200ms (TPS3823/4/5/8) 或 25ms (TPS3820) 的上電復(fù)位發(fā)生器 \n? 手動(dòng)復(fù)位輸入 (TPS3820/3/5/8)\n? 復(fù)位輸出提供低電平有效 (TPS3820/3/4/5)、高電平有效 (TPS3824/5) 和漏極開(kāi)路 (TPS3828)\n? 電源電壓監(jiān)控范圍：2.5V、3V、3.3V、5V\n? 看門(mén)狗計(jì)時(shí)器 (TPS3820/3/4/8)\n? 電源電流 15μA（典型值）\n? 5 引腳 SOT-23 封裝\n? 溫度范圍：?40°C 至 85°C;
