DESCRIPTION

SP6340 and SP6342

Dual

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 two supplies with two precision factory-set thresholds. 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 watchdog

functionalities. SP6340 and SP6342 are packaged in a 6-pin TSOT package. All devices are

fully specified over -40

C to +85

C temperature range.
