♠ Programmable Multi-Chemistry Fast-Charge Management IC
Lub bq2000 yog programmable, monolithic IC rau kev tswj ceev ceev ntawm nickel cadmium (NiCd), npib tsib xee hlau-hydride (NiMH), los yog lithium-ion (Li-Ion) roj teeb hauv ib leeg- lossis ntau yam kev siv tshuaj. Lub bq2000 xaiv cov roj teeb uas tsim nyog (xws li npib tsib xee lossis lithium) thiab ua tiav nrog qhov zoo tshaj plaws them nyiaj thiab txiav tawm algorithms. Cov txheej txheem no tshem tawm qhov tsis xav tau, tsis muaj nqi, lossis overcharged tej yam kev mob, thiab tso cai kom raug thiab nyab xeeb ntawm kev them nqi ceev.
Nyob ntawm cov chemistry, bq2000 muab ntau tus nqi txiav tawm:
• Peak voltage, PVD (rau NiCd thiab NiMH)
• Yam tsawg kawg nkaus them tam sim no (rau Li-Ion)
• Qhov kub siab tshaj plaws
• Lub sijhawm them nyiaj siab tshaj plaws
Rau kev nyab xeeb, bq2000 inhibits ceev ceev kom txog thaum lub roj teeb voltage thiab kub nyob rau hauv cov neeg siv cov kev txwv. Yog tias lub roj teeb hluav taws xob qis dua qhov ntsuas hluav taws xob tsawg, bq2000 siv dag zog-them rau lub roj teeb. Rau NiMH roj teeb, bq2000 muab qhov kev xaiv sab saum toj-off them kom ua kom lub roj teeb muaj peev xwm.
Kev sib xyaw ua haujlwm siab sib piv tso cai rau bq2000 los ua lub hauv paus rau kev ua tiav, kev ua haujlwm siab roj teeb charger rau ob qho tib si nickel-based thiab lithium-based chemistry.
• Tswj kev nyab xeeb ntawm kev them nqi ceev rau NiCd, NiMH, lossis Li-Ion roj teeb pob
• High-Frequency Switching Controller rau kev siv tau zoo thiab yooj yim Charger tsim
• Kev Tsim Nyog Ua Ntej Rau Kev Tshawb Fawb Txog Cov Cells luv, puas, lossis kub dhau
