DESCRIPTION
SP6330-SP6332- SP6334 Quad Power Supervisory Circuit Family is a family of
microprocessor reset supervisory circuits with multiple reset voltages. The family provides
low voltage monitoring ability for up-to four supplies with two precision factory-set thresholds
and two user defined custom thresholds. These circuits perform a single function: if any of
the input supply voltages drops below its associated threshold, reset outputs are asserted.
The SP6330, SP6332, and SP6334 are packaged in an 8-pin TSOT package. All devices are
fully specified over -40
o
C to +85
o
C temperature range.
