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 -40
