General Description
Many of today’s high performance FPGA’s, microprocessors,
DSP and industrial/embedded subsystems require sequencing
of the input power. Historically this has been accomplished
by: i) discretely using comparators, references & RC circuits;
ii) using expensive programmable controllers; or iii) with low
voltage sequencers requiring resistor drop downs and several
high voltage optocoupler or level shift components.
The PS10 saves board space, improves accuracy, eliminates
optocouplers or level shifts and reduces overall component
count by combining four timers, programmable input UV/
OV supervisors, a programmable POR, and four 90V open
drain outputs. A high reliability, high voltage, junction isolated
process allows the PS10 to be connected directly across the
high voltage input rails.
The power-on-reset interval (POR) may be programmed by a
capacitor on C
RAMP. To sequence additional systems, multiple
PS10s may be daisy-chained together. If at any time the input
supply falls outside the UV/OV detector range, the PWRGD
outputs will immediately become IN-ACTIVE.
The PS10 is available in a space saving 14-Lead SOIC
package.
