DS1233-10

The DS1233-10 from Analog Devices (formerly Maxim Integrated) is a supervisor IC that provides essential monitoring functions for microprocessor-based systems. It ensures system stability by detecting power supply out-of-tolerance conditions and managing external pushbutton resets.

Key electrical specifications include a monitored voltage of 4.375V and a reset timeout of 250ms minimum. The device offers an active-low reset output, which can be configured as open-drain or open-collector. It monitors a single voltage rail and is designed to automatically restart the microprocessor after a power failure or to maintain a reset for approximately 350ms after VCC returns to an in-tolerance condition.

The DS1233-10 is available in a through-hole TO-92-3 package, making it suitable for various PCB designs. Its operating temperature range is -40°C to 85°C, ensuring reliable performance in diverse environmental conditions. The internal circuitry debounces pushbutton switches, simplifying external component requirements and reducing the need for discrete components.

This supervisor IC is ideal for applications requiring robust power monitoring and reset control, contributing to the overall reliability and stability of embedded systems.
