The DS1233-5+T&R is a single-channel simple reset/power-on reset supervisor from the EconoReset series by Analog Devices, designed to monitor a single voltage rail and hold a microprocessor or logic circuit in reset until the supply stabilizes. The voltage threshold is set at 4.625V, making it suitable for 5V supply rails where the supervisor must assert reset before the rail drops below the processor's minimum operating voltage. Once the monitored voltage rises above the threshold, the output remains asserted for a minimum of 250ms — the reset timeout period — giving the system clock and power supplies time to settle before the processor starts executing code.
Fully ROHS3 compliant, with no exemptions listed, so it passes the materials declaration requirements for EU and UKCA markets without additional documentation.
