♠ LM7480-Q1 Ideal Diode Controller nwere Nchekwa Mbufu ibu
LM7480x-Q1 ezigbo onye na-ahụ maka diode na-ebugharị ma na-achịkwa mpụga azụ azụ N-Channel MOSFETs iji ṅomie ezigbo diode rectifier na njikwa ike ON / Gbanyụọ yana nchebe oke ọkụ. Ntinye ntinye obosara nke 3 V ruo 65 V na-enye ohere nchekwa na njikwa batrị 12-V na 24-V na-arụ ọrụ batrị ECU. Ngwaọrụ nwere ike iguzogide ma chebe ibu ahụ site na voltaji ọkọnọ na-adịghị mma ruo -65 V. Onye na-ahụ maka njikwa diode zuru oke (DGATE) na-ebugharị MOSFET mbụ iji dochie diode Schottky maka mgbanaka ntinye aka na njide voltaji mmepụta. Site na MOSFET nke abụọ na ụzọ ike ngwaọrụ ahụ na-enye ohere ịkwụpụ ibu (nchịkwa ON/ Gbanyụọ) yana nchebe oke ọkụ site na iji njikwa HGATE. Ngwaọrụ ahụ nwere atụmatụ nchedo nbibi oke voltaji enwere ike idozi. LM7480-Q1 nwere ụdị abụọ, LM74800-Q1 na LM74801-Q1.
