APPLICATION NOTE 4413
Sequencing Circuit Provides Pseudo Voltage Tracker
Abstract: This application note presents three approaches to track voltages between the supply rails. The
featured circuit, also the simplest approach, features the MAX6819 power-supply sequencer which performs
open-loop voltage tracking.
This design idea appeared in the June 1, 2006 issue of Portable Design magazine.
Modern microcontrollers, DSPs, and ASICs require multiple supply voltages for proper operation. With higher
speed and better processing capabilities, the voltages and fabrication geometries of these devices have been
scaled down to minimize power d
