BIAS 150ms DELAY Because of the reset delay time incorporated into the ADM181x GND TC series, these devices provide a safe startup for electronic systems. REFERENCE Before a system initializes, the power supply must stabilize. Using the ADM181x series ensures that there are typically 150 ms for the power supply to stabilize before the system resets and ADM1813/ADM1818 VCC safe system initialization begins. 5.5kΩ RESET RST MONITOR The ADM181x series of microprocessor reset circuits are available in low cost, space-saving SOT-23 and SC70 packages.
