DESCRIPTION
SP6339-SP6341 Triple µPower 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 three supplies with two precision factory-set thresholds and one
user defined custom threshold. These circuits perform a single function: if any of the input
supply voltages drops below its associated threshold, reset outputs are asserted. Products
in the family offer manual reset and watchdog functionalities. SP6339 and SP6341 are
packaged in an 8-pin TSOT package. All devices are fully specified over -40oC to +85oC
temperature range.
