Voltage-Monitoring and Sequencing Application Diagram Figure 20 depicts an application in which the ADM1184 monitors four separate voltage rails, turns on three regulators in a sequence, and generates a power-good signal to turn on a controller when all power supplies are up and stable. The main supply, in this case 3.3 V, powers up the device via the VCC pin. The VIN1 pin monitors the main 3.3 V supply. In this example application, OUT1 is connected to the enable pin of a regulator. Before the voltage on VIN1 reaches 0.6 V, this output is switched to ground, disabling Regulator 1. When the main system voltage reaches 2.9 V, VIN1 detects 0.6 V. This causes OUT1 to assert, which drives the enable pin of Regulator 1 high, thus turning on its output. The 2.5 V output of this regulator begins to rise and is detected by input Pin VIN2. When VIN2 detects the 2.5 V rail rising above its voltage threshold point, it asserts OUT2, which turns on Regulator 2. The same scheme is implemented with the other input and output pins. Every rail that is turned on via an output pin, OUTx, is monitored via an input pin, VIN(x + 1). When all four monitored supplies are above their programmed threshold levels PWRGD asserts after a 190 ms (typical) delay. |
