Description

SP6339-SP6341 Triple Power Supervisory Circuit Family is a family of microprocessor eset supervisory circuits with multiple reset voltages. The family provides low voltage onitoring ability for up to three supplies with two precision factory-set thresholds and one ser defined custom threshold. These circuits perform a single function: if any of the input upply voltages drops below its associated threshold, reset outputs are asserted. Products n the family offer manual reset and watchdog functionalities. SP6339 and SP6341 are ackaged in an 8-pin TSOT package. All devices are fully specified over -40 to +85emperature range.
