DS1814BR-10-U+

Supervisors Overview

The DS1814BR-10-U+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides reset signals for 5 Volt and 3.3 Volt systems. The device features a push-pull output and operates within a supply voltage range of 2.7V to 5.5V. It includes a programmable timeout period and supports active-low or active-high reset configurations. The component is housed in an SOT-23-5 package and is designed for surface-mount installation.

Supervisors Feature Summary

• Provides reliable system reset supervision for microprocessors
• Supports both 5V and 3.3V logic levels
• Features programmable reset timeout duration
• Offers configurable active-high or active-low reset output

Supervisors Applications

• Microprocessor system monitoring
• Power supply supervision for embedded controllers
• Brown-out detection circuits
• Watchdog timer integration

Supervisors Procurement Notes

Verify the specific suffix 'U+' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the 'BR' suffix corresponds to the correct temperature grade and packaging format. Ensure compatibility with existing board layout constraints for the SOT-23-5 footprint before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor is required for standard digital logic voltages. Consider the programmable timeout feature if precise reset delay timing is necessary for the target application. Verify that the SOT-23-5 package size fits within the available PCB area compared to alternative packages like SC-74A.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, which specializes in low-power supervisory circuits. These devices are commonly used in industrial, consumer, and computing applications where stable power sequencing and reliable reset generation are critical for system integrity and data protection.

Supervisors Replacement Considerations

Check for direct substitutes such as the DS1819 series, which offers similar functionality in different packages. Verify pinout compatibility and electrical specifications against alternatives like the MAX809 or MAX811 families before substitution.
