Quad µPower Supervisory Circuits

with Manual Reset & Watchdog

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
