During steady state operation, the input voltage of the TPS7H3014 must be between 3V and 14V. A minimum bypass capacitance of at least 0.1μF is needed between V_IN and GND. The input bypass capacitors should be placed as close to the sequencer IC as possible. Is recommended that V_IN slew rate is controlled between 10V/μs to 1mV/μs for proper IC operation.

The voltage applied at V_IN serves as the input for the internal regulator that generates the VLDO voltage, typically 3.29V. At input voltages less the 3.29V (typ), the VLDO voltage will follow the voltage at V_IN. Recommended capacitance for VLDO is 1μF. Unused SENSE2 to SENSE4 can be tied to VLDO to by-pass the channel delay during sequence up and down. It is recommended to pull-up the FAULT pin to VLDO via a 10kΩ resistor, but otherwise it is recommended not to externally load this pin due to limited output current capability. During power up, the user should wait at least the 2.8ms (t_{Start_up_delay}) after V_IN > UVLO_RISE before attempting to start a sequence up, this is due to internal time constants in the device.

Each device generates an internal 1.2V bandgap reference that is utilized throughout the various internal control logic blocks. This is the voltage present on the REFCAP pin during steady state operation. This voltage is divided down to produce the reference for the comparator inputs SENSE_x (599mV typ), UP (598mV typ) and DOWN (498mV typ). The V_{TH_SENSEx} reference is measured at the EN_x outputs to account for offsets in the error amplifier and maintains regulation within ±1% across: voltage, temperature, and radiation TID (up to 100krad in Silicon). This tight reference tolerance allows the user to monitor voltage rails with high accuracy. A 470nF capacitor to GND is required at the REFCAP pin for proper electrical operation as well as to ensure robust SET performance of the device.
