一般說明：MAX14870ETC+T
MAX14870ETC+T/MAX14872 電機驅動器提供了一個小型、用于驅動和控制的低功耗且簡單的解決方案有刷直流電機和繼電器之間的電壓4.5V 和 36V。極低的驅動器導通電阻降低了功耗。這些驅動器采用無電荷泵設計，適用于減少外部元件和低電源電流。集成的快速衰減電流調節允許用戶調節峰值啟動電機電流，并且需要最少的外部組件。單獨的電壓檢測輸入 (SNS) 可降低電流由于寄生走線電阻引起的感測錯誤。
MAX14870/MAX14872 具有擊穿保護和內部續流二極管，可吸收電感電機電流。驅動器輸出有短路保護從短路到地，到電源，以及 M1 和M2。低電平有效 FAULT 輸出信號熱過載和故障條件下的過電流。
MAX14870ETC+T具有 PWM 和方向控制輸入，而 MAX14872 具有正向和反向輸入方向控制。請參閱功能表。
MAX14870ETC+T/MAX14872 提供 12 引腳封裝(3mm x 3mm) TDFN-EP 封裝并在-40°C 至 +85°C 溫度范圍。
