SLVSFH6C January 2021 – December 2021 TPS61094
The TPS61094 has four operation modes by the EN pin and MODE pin selection. Table 7-4 lists the operation modes of the device with respect to the status of the EN and MODE pin.
|Forced bypass||0||0||√||×||×||Turn on bypass MOSFET, turn off boost/buck, VOUT = VIN|
|True shutdown||0||1||×||×||×||Bypass disconnect, turn off boost/buck, VOUT = 0 V|
|Forced buck||1||0||√||×||√||Buck enabled, turn on bypass MOSFET, VOUT = VIN while charging the supercap or backup battery|
|Auto buck or boost||1||1||√||×||√||Buck enable, when VIN > target VOUT +100 mV and VOUT > target VOUT, supercap is charged by buck|
|1||1||√||√||×||Boost and bypass enabled; when VOUT + 100 mV > VIN > target VOUT and VOUT = target VOUT, VOUT is from both VIN through bypass and supercap by boost.|
|1||1||×||√||×||Boost enable; when VIN < target VOUT, VOUT is powered from supercap by boost.|
