Abstract
Power-sequencing controllers are connected to allow more complex power sequencing and/or larger numbers of voltage supplies to be monitored than with a single controller. Power-on-reset (POR) output signals from the 'slave' controllers are connected by a wired-OR, and the composite output is used as a reset signal or indicator signal by the 'master' controller. An output from the master controller coupled to the composite input signal is connected with the {overscore (POR)} output of the master controller by a wired-OR, and this composite signal is coupled to the reset terminals of the slave controllers. Connecting controllers in a master/slave configuration allows prevents any of the slave devices from starting until all the devices have been released, resulting in synchronous processing of subsequent signals and events.
