36V, 3.8A Two H-Bridge for Dual Brushed or Single Stepper Motor Drive

General Description The MAX22211 is a dual 36V, 3.8AMAX H-bridge. It can be used to drive two brushed DC motors or a single stepper motor. The H-bridge FETs have very low impedance resulting in high driving efficiency and low heat generation. The typical total RON (high-side + low-side) is 0.

用于兩個(gè)有刷或單個(gè)步進(jìn)電機(jī)驅(qū)動(dòng)器的 36V、3.8A 雙 H 橋

MAX22211 是一款雙通道 36V、3.8A MAX H 橋。它可用于驅(qū)動(dòng)兩個(gè)有刷直流電機(jī)或單個(gè)步進(jìn)電機(jī)。H 橋 FET 具有非常低的阻抗，因此，驅(qū)動(dòng)效率較高且散熱很少?？?RON（高側(cè) + 低側(cè)）的典型值為 0.25Ω。每個(gè) H 橋可使用三個(gè)邏輯輸入（DIN1、DIN2、EN）單獨(dú)進(jìn)行脈寬調(diào)制 (PWM) 控制。\n\n MAX22211 具有精確的電流驅(qū)動(dòng)調(diào)節(jié) (CDR) 功能，可用于限制有刷直流電機(jī)的啟動(dòng)電流或控制步進(jìn)操作的相電流。電橋輸出電流由無損耗式集成電流檢測(cè) (ICS) 套件進(jìn)行檢測(cè)，然后與用戶可配置的閾值 (ITRIP) 進(jìn)行比較。當(dāng)電橋電流超過 ITRIP 閾值 ? 兩個(gè) H 橋，最大工作電壓為 +36V\n? 每個(gè) H 橋的電流額定值（TA = 25°C 時(shí)的典型值）\n?IRMS = 2ARMS（每個(gè)全橋推薦的最大 RMS 電流）\n? 集成電流驅(qū)動(dòng)調(diào)節(jié)?ICS 無需使用體積較大的外部電阻，提高了效率\n? 電流驅(qū)動(dòng)調(diào)節(jié)監(jiān)控輸出引腳（CDRA、CDRB）\n?半滿量程 (HFS) 引腳可在低電流范圍內(nèi)提高電流控制精度;
