The TPS7H3014 is an integrated, 3V to 14V, four-channel radiation-hardness-assured power-supply sequencer. Channel count can be expanded by connecting multiple devices in a daisy-chain configuration. The device provides sequence up and down control signals for integrated circuits (IC) with active high ("on") inputs. In addition SEQ_DONE and PWRGD flags are provided to monitor the sequence and power status of the monitored power tree.

An accurate 599mV ±1% threshold voltage and a 24µA ±3% hysteresis current provide programmable rise and fall monitoring voltages. The rise and fall delay time is globally programmed via a single resistor. Also, a time-to-regulation timer is provided to track the rising voltage on SENSEx. In addition to these features, a FAULT detection pin is incorporated to monitor internally generated faults and provide increased system level reliability for power sequencing space applications. A standard microcircuit drawing (SMD) is available for the QML variant, 5962R2320101VXC.
