♠ DRV8876 H-Bridge Tsav Tsav Tsheb Nrog Kev Ruaj Ntseg Tam Sim No thiab Kev Cai
DRV887x tsev neeg ntawm cov khoom siv yog cov tsav tsheb hloov tau yooj yim rau ntau yam kev siv. Cov khoom siv sib xyaw ua ke N-channel H-bridge, them twj tso kua misregulator, tam sim no sensing thiab tswj, tam sim no proportional tso zis, thiab tiv thaiv circuitry. Tus nqi twj tso kua mis txhim kho efficiency los ntawm kev tso cai rau ob qho tib siHigh-sab thiab qis-sab N-channels MOSFETs thiab 100% kev txhawb nqa lub voj voog. Cov tsev neeg ntawm cov khoom siv los ntawm tus pin-rau-tus pin, scalable RDS (on) kev xaiv los txhawb cov khoom sib txawv nrog cov qauv tsim tsawg heev.
Integrated tam sim no sensing tso cai rau tus neeg tsav tsheb tswj lub cev muaj zog tam sim no thaum pib thiab siab load txheej xwm. Ib qho kev txwv tam sim no tuaj yeem teeb tsa nrog kev siv hluav taws xob sab nraud kho tau. Tsis tas li ntawd, cov cuab yeej muab cov zis tam sim no proportional rau lub cev muaj zog load tam sim no. Qhov no tuaj yeem siv los kuaj xyuas lub cev muaj zog lossis hloov pauv hauv cov xwm txheej thauj khoom. Kev sib xyaw ua ke tam sim no siv lub iav sab hauv tam sim no architecture, tshem tawm qhov xav tau ntawm lub zog loj shunt resistor, txuag lub rooj tsav xwm cheeb tsam thiab txo cov nqi system.
Lub zog pw tsaug zog qis yog muab los ua kom tau txais ultralow quiescent tam sim no kos los ntawm kev kaw feem ntau ntawm cov hluav taws xob sab hauv. Cov yam ntxwv tiv thaiv sab hauv yog muab rau cov khoom siv hluav taws xob tsis muaj hluav taws xob (UVLO), lub twj tso kua mis hauv qhov hluav taws xob (CPUV), tso zis ntau dhau (OCP), thiab ntaus ntawv overtemperature (TSD). Cov xwm txheej tsis raug yog qhia ntawm nFAULT.
