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 -40o C to +85o C temperature range.
