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, 5962R2320101VXC.
