3 說明
DRV8340-Q1 器件是一款適用于三相應用的 集成式柵極驅動器。此器件具有三個半橋柵極驅動器，每個驅動器都能夠驅動高側和低側 N 溝道功率 MOSFET。專用源極與漏極引腳支持對電磁閥應用進行獨立 MOSFET 控制。DRV8340-Q1 使用集成式電荷泵為高側 MOSFET 生成足夠的柵極驅動電壓，并使用線性穩壓器為低側 MOSFET 生成足夠的柵極驅動電壓。此智能柵極驅動架構支持高達 1A 的峰值柵極驅動拉電流和 2A 的峰值柵極驅動灌電流。DRV8340-Q1 可由單一電源供電，支持適用于柵極驅動器的 5.5 至 60V 寬輸入電源電壓范圍。
6x、3x、1x 和獨立輸入 PWM 模式可簡化與控制器電路的連接。柵極驅動器和器件的配置設置具有高度可配置性，可通過 SPI 或硬件 (H/W) 接口實現。
提供了低功耗睡眠模式，實現較低的靜態電流消耗。針對欠壓鎖定、電荷泵故障、MOSFET 過流、MOSFET 短路、相位節點電源和接地短路、柵極驅動器故障和過熱情況提供內部保護功能。故障狀況及故障詳情可通過 SPI 器件型號的器件寄存器顯示在 nFAULT 引腳上。
