MAX825SEXK-T

Supervisors Overview

The MAX825SEXK+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a compact SC-70-5 surface-mount package. It monitors a single voltage input with a threshold of 2.93 V and an overvoltage threshold of 2.96 V. The device features active high and active low push-pull outputs, manual reset capability, and a reset delay time of 200 ms. Operating from a supply voltage up to 5.5 V with a quiescent current of 2 uA, it functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides dual active high and active low push-pull reset signals for flexible logic interfacing
• Includes manual reset functionality allowing user-initiated system restarts
• Features ultra-low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor system supervision
• Battery-powered portable electronics
• Low-voltage digital circuits requiring reliable power monitoring

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as variations such as +T indicate reel packaging while other suffixes may denote cut tape or specific environmental ratings. Confirm RoHS compliance status through manufacturer datasheets. Ensure the SC-70-5 footprint matches your PCB design constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both active high and low outputs is required. The 2.93 V threshold suits 3.3 V systems. Consider the MAX825YEXK+T if variable thresholds are needed, or the MAX823SEXK+T if watchdog timer integration is necessary for enhanced system reliability.

Supervisors Part Context

Part of the MAX823-MAX825 series of microprocessor supervisors designed for low-voltage systems. These devices offer simple reset generation without complex configuration. The MAX825 variant specifically distinguishes itself by providing complementary output polarities, enhancing compatibility with diverse logic families in embedded designs.

Supervisors Replacement Considerations

MAX825YEXK+T offers similar functionality with selectable threshold voltages. MAX823SEXK+T includes an integrated watchdog timer. Verify pinout compatibility and output drive strength when substituting these parts in existing designs.
