3 Description

The TPS7H3014 is an integrated, 3V to 14V, fourchannel

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, 5962R23201VXC.
