LB11852RVは、速度帰還による速度制御機能を有する、単相バイポーラ駆動のモータプリドライバである。少ない外付け部品で、高効率、低消費で静音性が高く、且つ、回転数精度も高い可変速駆動のファンモータが構成できる。小型外形の採用により、速度制御を必要とする小型ファンモータ駆動に最適である。
特長
 
  • 単相全波駆動プリドライバ
    外付けPower-Trに、PMOS-NMOS使用し、低飽和出力、単相全波駆動により高効率、低消費の駆動が可能である。
  • 速度制御回路内蔵
    速度帰還による速度制御(クローズドループ制御)により、オープンループ制御に比べて回転数精度の向上、および電源電圧変動や負荷変動時の回転数変動の低減が可能である。なお、可変速の方式は、他励式上側ダイレクトPWM方式である。
  • 外部PWM 入力、アナログ電圧入力による速度制御が可能
    速度制御のPWM Duty、アナログ電圧どちらにも対応する。
  • ソフトスタート回路内蔵
  • 最低速設定端子
    外付けの抵抗により、最低速の設定が可能である。
  • 電流制限回路内蔵
    起動時、ロック時にチョッパ方式の電流制限をする。
  • 無効電流カット回路内蔵
    相切り替え前の無効電流をカットし、静音化、低消費の駆動が可能である。
  • 自動復帰型拘束回路内蔵
  • RD(ロック検知)出力
アプリケーション
  • 小型ファンモータ駆動
