ISL6536A, Four Channel Supervisory IC

ISL6536A 1 2 PIN NAME VDD PGOOD Bias IC from nominal 2.7V to 5V PGOOD is the boolean AND function of all the UV inputs being satisfied.

This is an open drain output and can be pulled high to the appropriate level with an external resistor.

Additionally a 20kΩ pull up to VDD is provided internally.

® ISL6536A 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 comparison 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
