DS1818R-10+T&R Description

Short technical summary and product information.

The DS1818R-10+T&R is a supervisor integrated circuit designed to monitor power supply status and ensure reliable processor operation. It features a voltage monitor that detects out-of-tolerance conditions, generating an active-low reset signal. This reset signal is maintained for approximately 150ms after the power supply returns to normal, allowing for system stabilization.

Key electrical specifications include a supply voltage of 2.88V and an active-low reset output that can be configured as open-drain or open-collector. The reset timeout is typically 100ms. The device is designed to operate within a temperature range of -40°C to 85°C.

This supervisor IC is available in a SOT-23-3 surface mount package, specifically TO-236-3, SC-59, or SOT-23-3. Its open-drain output is efficient, saving power and space. The DS1818R-10+T&R is suitable for applications requiring precise power-fail detection and automatic microprocessor restart after power interruptions.
