Description
Many of today’s high performance FPGA’s, Microproces-
sors, DSP and industrial/embedded subsystems require
sequencing of the input power. Historically this has been
accomplished: i) discretely using comparators, references
& RC circuits; ii) using expensive programmable control-
lers; or iii) with low voltage sequencers requiring resistor
drop downs and several high voltage optocoupler or level
shift components.
The PS10/11 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 PS10/11 to be con-
nected directly across the high voltage input rails.
The power-on-reset interval (POR) may be programmed
by a capacitor on Cramp. To sequence additional sys-
tems, PS10/11 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. Down sequencing may be accomplished with
additional components (see page 11).
The PS10/PS11 is available in a space saving SO-14
package.
