The family provides low voltage monitoring ability for up-to four supplies with two precision factory-set thresholds and two user defined custom thresholds. These circuits perform a single function: if any of the input supply voltages drops below its associated threshold, reset outputs are asserted. The SP6330, SP6332, and SP6334 are packaged in an 8-pin TSOT package. All devices are fully specified over -40oC to +85oC temperature range.
