NXP Semiconductors MC33HB2002 IC和驅動器是SMARTMOS單片半橋IC,通過SPI配置和診斷功能增強。這些電源IC能夠控制峰值電流大于10A的電感負載,標稱連續平均負載電流為3A。MC33HB2002 IC設計用于滿足ISO26262安全要求,符合汽車應用的嚴格要求,并符合AEC-Q100標準。這些電源IC通過誤差小于5%的電流鏡輸出信號提供高精度的實時電流反饋。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氣門控制、廢氣再循環控制 (EGR)、電動泵、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:
某些函數被強制關閉,FS_B信號被鎖定到邏輯[0]表示故障
