數(shù)據(jù): NXP Semiconductors MC33HB2002 IC和驅(qū)動(dòng)器.pdf
NXP Semiconductors MC33HB2002 IC和驅(qū)動(dòng)器是SMARTMOS單片半橋IC,通過(guò)SPI配置和診斷功能增強(qiáng)。這些電源IC能夠控制峰值電流大于10A的電感負(fù)載,標(biāo)稱(chēng)連續(xù)平均負(fù)載電流為3A。MC33HB2002 IC設(shè)計(jì)用于滿足ISO26262安全要求,符合汽車(chē)應(yīng)用的嚴(yán)格要求,并符合AEC-Q100標(biāo)準(zhǔn)。這些電源IC通過(guò)誤差小于5%的電流鏡輸出信號(hào)提供高精度的實(shí)時(shí)電流反饋。MC33HB2002 IC的工作電壓范圍為5V至28V。這些電源IC非常適合用于電子節(jié)氣門(mén)控制、廢氣再循環(huán)控制 (EGR)、電動(dòng)泵、渦輪和廢物擋板控制。
The MC33HB2002 operates in the following modes:
• Sleep mode:
MC33HB2002 functions are disabled. The current consumption does not exceed the sleep-state current specification.
• Standby mode
MC33HB2002 logic is fully operational with the outputs in a high-impedance state.
• Normal mode:
MC33HB2002 functions are fully operational. Any detected faults transition the device to Fault mode.
• Fault mode:
某些函數(shù)被強(qiáng)制關(guān)閉,F(xiàn)S_B信號(hào)被鎖定到邏輯[0]表示故障
