ISL6536A Datasheet | Intersil

® Data Sheet January 2004 FN9136 Four Channel Supervisory IC The ISL6536A is a four channel supervisory IC designed to monitor voltages >, = 0.7V. This IC bias range is from 2.7V to 5V but can supervise any positive voltage using an external resistor divider to translate to a lower voltage for parison to the internal 0.63V reference. Once properly biased and enabled when all four voltage monitor (VMON) inputs are satisfied the PGOOD output will be immediately released to go high to signal that voltage is valid on all four rails. Subsequently when the monitored voltage on any rail drops below its user defined threshold point, the PGOOD output is pulled low. Each rail’s VMON...
