DS1818R10TR

The Maxim Integrated DS1818R10TR is an EconoReset Supervisory Circuit with a pushbutton feature, providing reliable power monitoring and manual reset capability for industrial applications. It utilizes a temperature-compensated reference to detect supply voltage out-of-tolerance conditions, activating a reset signal to protect microprocessor operation. After power stabilization, it maintains reset for approximately 150 ms.

The device also monitors a pushbutton for manual reset, holding the reset line low for about 150 ms when pressed. Designed for industrial environments, it features an open-drain output with an internal 5.5 kΩ pull-up resistor, simplifying circuit design and reducing power consumption. No complicated setup is required, making it suitable for ensuring system stability and providing manual overrides.

Key electrical specifications include a supply voltage range of 1.0 to 5.5 V, a reset active time of 100 to 250 ms, and a maximum output current of 10 mA at 0.4 V. The Vcc trip points vary depending on the specific model, with ranges like 2.98 to 3.15 V for DS1818-5. The operating temperature range is -40°C to +85°C.

This power supervisor is supplied in a Tape & Reel package. Its robust design ensures dependable power monitoring and manual reset functions during power fluctuations, making it ideal for safeguarding systems and ensuring operational continuity.
