DS1836CS-10+T&R

Supervisors Overview

The DS1836CS-10+T&R is a MicroManager supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It provides precise monitoring for 5V and 3.3V power supplies, generating reset signals during out-of-tolerance conditions. The device features an internal battery backup switch that activates when VCC drops below specified thresholds (3.8V for 5V versions, 2.6V for 3.3V versions), ensuring continuous operation from a secondary source. It maintains the reset state for 350ms after VCC returns to normal. The component operates within a temperature range of -40°C to +85°C and utilizes an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Monitors voltage status and generates internal power-fail signals during out-of-tolerance conditions
• Switches to battery supply automatically when main voltage degrades below threshold levels
• Maintains reset assertion for 350ms after main supply returns to tolerance
• Provides precision temperature-compensated voltage reference and sensor

Supervisors Applications

• Systems designed to operate with dual power supplies
• PIC microprocessor applications requiring reliable supervision
• Battery-operated handheld applications needing orderly shutdown or backup switching
• Nonvolatile memory systems requiring power-fail warnings

Supervisors Procurement Notes

Verify current availability status as this part number may be subject to limited supply or discontinuation. Confirm the specific suffix matches the required voltage version (5V vs 3.3V) and package type. Check manufacturer documentation for RoHS compliance details and ensure the ordering suffix corresponds to the tape and reel configuration if applicable. Cross-reference with official distributor catalogs for accurate stock information.

Supervisors Selection Notes

Select this component for applications requiring integrated power management and supervision in space-constrained designs. It reduces the need for discrete components by combining voltage monitoring, reset generation, and battery backup switching in a single IC. Ensure the system voltage aligns with the specific variant's operating range. Consider the 350ms reset delay for timing-critical microprocessor resets. Verify thermal requirements against the industrial temperature range specification.

Supervisors Part Context

The DS1836 belongs to the MicroManager family, which integrates essential system functions for microprocessor-based designs. This series simplifies design by providing power-on reset, power-fail indication, and battery backup control. The CS-10 suffix typically denotes the commercial temperature range and specific monitoring thresholds. It serves as a cost-effective alternative to multiple discrete supervisor components, offering high accuracy and low current consumption.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Users should consult the manufacturer's official replacement guide or contact sales engineering for direct equivalents. Generic replacements may not match the specific battery switch thresholds or reset timing characteristics.
