DS1815R-5/T&R

Supervisors Overview

The DS1815R-5 is a supervisory microprocessor circuit designed to monitor voltage levels and provide reset signals for digital systems. It features a fixed output threshold of 4.63V, ensuring reliable operation within standard logic families. The device includes an active-low reset output with a programmable timeout period, typically adjustable via external components or internal settings depending on the specific variant configuration. It operates over an extended temperature range and is housed in a compact SOT-23 package, suitable for space-constrained applications requiring robust power management.

Supervisors Feature Summary

• Monitors supply voltage and generates reset signal upon undervoltage conditions
• Provides active-low reset output with configurable timeout delay
• Operates within specified voltage thresholds for stable system initialization

Supervisors Applications

• Microcontroller system power supervision
• Embedded controller reset generation
