SC8551A Single Cell High Efficiency 8-A Switched Capacitor Direct Charger
■ SC8551A is a 97% efficiency, 8-A battery charging solution using a switched cap architecture. The switched cap architecture and the integrated FETs are optimized to enable a 50% cycle, allowing the cable current to be half the current delivered to the battery, reducing the losses over the charging cable as well as limiting the temperature rise in the application.
■ SC8551A adopts 56pin CSP 2.995mm X 3.255mm package.
● Features:
■ 10-way system protection
▲ VAC_OVP
▲ IBUS/IBAT/VBAT regulation
▲ VDROP_OVP
▲ VBUS_OVP
▲ IBUS_OCP
▲ IBUS_UCP
▲ VOUT_OVP
▲ VBAT_OVP
▲ IBAT_OCP
▲ TSHUT
■ 6-way charge-pump protection
▲ VBUS_ERROR_HI protection before switch
▲ VBUS_ERROR_LO protection before switch
▲ CFLY short/open detection before switch
▲ CDRV short/open detection before switch
▲ PMID2OUT_OVP during switch
▲ PMID2OUT_UVP during switch
■ 7-channel 12-bit ADC
▲ VAC,VBUS,IBUS,VOUT,VBAT,IBAT,TDIE
