♠ TPS212x 2.8-V kuya ku-22-V Amandla Abalulekile E-MUX ane-Switchover Engenamthungo
Amadivayisi we-TPS212x yi-Dual-Input, Single-Output (DISO) Power Multiplexer (MUX) afaneleka kahle kumasistimu ahlukahlukene anemithombo yamandla eminingi. Amadivayisi azothola ngokuzenzakalelayo, akhethe, futhi ashintshe kalula phakathi kokufaka okutholakalayo.
Okubalulekile kunganikezwa ngokuzenzakalelayo ku-voltage ephezulu kakhulu yokufaka noma kunikezwe ngesandla okokufaka kagesi okuphansi ukuze kusekelwe kokubili ukusebenza kwe-ORing kanye Nokukhethwa Komthombo. I-voltage supervisor isetshenziselwa ukukhetha umthombo wokufaka.
Ukusebenza kwe-Ideal Diode kusetshenziselwa ukuguqula kalula phakathi kwemithombo yokufaka. Ngesikhathi sokushintsha, ukwehla kwamandla kagesi kulawulwa ukuze kuvinjwe amandla abuyela emuva ngaphambi kokuthi kwenzeke futhi kunikeze amandla angaphazamiseki emlayishweni ngamandla amancane okubamba.
Umkhawulo wamanje usetshenziswa ngesikhathi sokuqalisa nokushintsha ukuvikela ezenzakalweni ezidlulele, futhi uvikela idivayisi phakathi nokusebenza okuvamile. Umkhawulo wamanje ophumayo ungalungiswa nge-resistor eyodwa yangaphandle.
Amadivayisi we-TPS212x ayatholakala nge-WCSP kanye nezinketho zephakheji ezincane ze-VQFN-HR eziphawulelwe ukusebenza ebangeni lokushisa elingu--40°C kuya ku-125°C.
