MAX825REUK

The MAX825REUK is a low-power microprocessor (μP) supervisory circuit from Maxim Integrated (now part of Analog Devices). It monitors system voltage and provides a reset signal to the μP during power-up, power-down, or brownout conditions, ensuring reliable operation.
Key features:
- Voltage monitoring: Tracks VCC (1.8V to 5V) and asserts reset if voltage drops below a preset threshold.
- Manual reset input: Allows external reset triggering via a pushbutton.
- Low quiescent current: Consumes minimal power (typ. 5μA), ideal for battery-powered applications.
- Reset timeout delay: Guarantees a stable reset pulse (typ. 140ms).
- Small package: SOT23-5 for space-constrained designs.
Common applications include embedded systems, industrial controls, and portable electronics where reliable power management is critical.
For detailed specs, refer to the datasheet.
