ADM6315 is a reliable voltage-monitoring device suitable for microprocessor systems, controllers, intelligent instruments, automotive systems, safety systems, and portable instruments. It features temperature adjustment, low power consumption, precision voltage monitoring, and built-in manual reset.
The ADM6315 is an open‑drain microprocessor supervisory circuit that monitors supply voltages from 2.5 V to 5 V in 100 mV steps. It provides a debounced manual reset input and an open‑drain reset output that can sink current from higher‑voltage sources, making it suitable for microprocessor systems, controllers, automotive and safety applications.
The device is offered in a compact 4‑lead SOT‑143 package and features selectable reset timeout periods (1 ms, 20 ms, 140 ms, 1120 ms), low typical supply current (5 pA), and an ESD rating of 25 kV. It operates over –40 °C to +125 °C and includes detailed pin functions, thermal specifications, and ordering information.
