The TPS389x family also has a logic enable pin (ENABLE or ENABLE) to power on and off the output. With the TPS3895, for example, when the input voltage pin (SENSE) rises above the threshold, and the ENABLE pin is high, then the output pin (SENSE_OUT) goes high after the capacitoradjustable delay time. When SENSE falls below the threshold or ENABLE is low, then SENSE_OUT goes low. For truth tables, see Table 1 and Table 2. For TPS389xA versions, both SENSE and...
