R5434D402AA R5434D Caricabatteria a 2 celle IC Power Manager IC

R5434D402AA protezione da sovraccarico IC serie R5434D protezione batteria ai polimeri di litio agli ioni di litio PMIC per protezione secondaria

Dettagli: Gestione batteria serie R5434D Protezione da 2 celle a 5 celle PMIC-Power manager IC

LINEAMENTI:

L'R5434D è un circuito integrato di protezione da sovraccarico per batterie secondarie seriali agli ioni di litio/polimeri di litio da 2 a 5.Quando viene rilevato un sovraccarico, dopo il tempo di ritardo fissato internamente dall'IC, l'uscita di COUT diventa "H".Dopo aver rilevato il sovraccarico, quando la tensione della cella diventa inferiore alla tensione di rilascio del sovraccarico, lo stato di sovraccarico viene rilasciato.Forzando VDD+3.0V o più al pin CTLC, il tempo di test del circuito di protezione può essere ridotto e il tempo di ritardo di sovraccarico diventa circa 1/30.Il tipo di uscita è CMOS.
