ADM6384 is a supervisory circuit manufactured by Analog Devices, USA. It monitors the power supply voltage levels in microprocessor-based systems. When the supply voltage rises to a preset threshold level, a power-on reset signal is generated. The debounced manual reset input of the ADM6384 can be used to initiate a reset by means of an external pulse.
The ADM6384 supervisory circuit monitors power‑supply voltage in microprocessor‑based systems and generates a reset when the voltage falls below a programmable threshold. It is suited for microprocessor systems, computers, controllers, intelligent instruments, and portable equipment.
Key features include 31 selectable reset‑threshold options (1.58 V to 5.0 V), four reset‑timeout periods (1 ms, 20 ms, 140 ms, 1120 ms), a manual reset input, a push‑pull active‑low reset output, and operation over –40 °C to +125 °C in a 4‑lead SC70 package.
