Functional Pin Description
5VSBY (Pin 1)
5VSBY is the bias supply of the ISL6537A. It is typically
connected to the 5V standby rail of an ATX power supply.
During S4/S5 sleep states the ISL6537A enters a reduced
power mode and draws less than 1mA (I
5VSBY supply. The supply to 5VSBY should be locally
bypassed using a 0.1μF capacitor.
