IMP3253D(S)是集成高壓半橋驅(qū)動(dòng)器與類似工業(yè)標(biāo)準(zhǔn)555定時(shí)器于一體的柵極驅(qū)動(dòng)芯片,CT腳具有保護(hù)關(guān)斷特性,可以使用低電壓控制信號(hào)使高低側(cè)柵級(jí)驅(qū)動(dòng)輸出失.另外,驅(qū)動(dòng)器輸出脈沖寬度相同,一量VCC上升到欠壓閉鎖閥值,驅(qū)動(dòng)器能以更加穩(wěn)定的頻率開(kāi)始起振.通過(guò)降低柵極驅(qū)動(dòng)器di/dt的峰值 和提高欠壓閉鎖閥值的滯后電壓到1V,使電路的抗噪性有了實(shí)質(zhì)性的提高.電路引腳的整體抗噪保護(hù)方面也有所改進(jìn).
