SP6330 Family: Selecting a Multi-Voltage Supervisor
2006 Sipex Corporation
Page 1 of 6
Introduction
The primary function of a microprocessor (P) supervisor circuit is to ensure that
the input supply voltage of a microprocessor is at proper levels during power up,
power down and brownout conditions. If the input supply voltage to a
microprocessor is below its required operating range, it could cause code-
execution errors, memory corruption and latch up. The supervisor will constantly
monitor the input supply to the microprocessor, and in the event this supply
voltage falls below a certain threshold, the RESET output will be asserted. Many
of today’s power products require several different voltage rails for powering
various components. The microprocessor itself can have a separate core voltage
and logic voltage. Other components such as DSPs, ASICs and microcontrollers
can have their own unique voltage requirements. To service this demand of
monitoring multi-voltage systems, Sipex has developed the SP6330 family. The
SP6330 family is a series of multi-voltage supervisors that offer monitoring of up
to 4 separate supplies and are equipped with specialized features. A complete
listing of products and features are listed in Figure 4 at the end of this note.
