ZHCSN56C January 2021 – December 2021 TPS61094
PRODUCTION DATA
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.
| MODES | EN | MODE | BYPASS | BOOST | BUCK | FUNCTION |
|---|---|---|---|---|---|---|
| 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. |
