Accurate reset signals are generated during momentary power interruptions, or whenever power supply voltages sag to intolerable levels. Several reset threshold versions of the device are available. A totem-pole output topology is incorporated to provide both current source and sink capability to the user. SA56614-XX is available in the SOT23-5 surface mount package.
