SP706SEU-L

Supervisors Overview

The SP706SEU-L is a low-power microprocessor supervisory circuit manufactured by MaxLinear, Inc. It monitors a single voltage input with a threshold of 2.93V and provides an active-low push-pull reset output. The device features a manual reset input and a watchdog timer with a 1.6-second timeout. It operates within a supply voltage range of 1V to 5.5V and supports surface-mount installation in an 8-MSOP package. The component is rated for industrial temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 2.93V threshold for system stability
• Integrates a debounced manual reset input compatible with TTL/CMOS logic levels
• Includes an independent watchdog timer to detect software malfunctions
• Delivers a guaranteed reset pulse width to ensure proper processor initialization

Supervisors Applications

• Microprocessor power supply supervision in embedded systems
• Industrial control equipment requiring reliable reset sequences
• Communication devices needing watchdog functionality for fault recovery

Supervisors Procurement Notes

Verify the exact manufacturer designation as sources attribute this part to both MaxLinear and Exar Corporation due to corporate acquisitions. Confirm the specific suffix indicates the MSOP-8 package variant. Check current lifecycle status as listings indicate obsolete or limited availability across various distributors. Ensure compatibility with existing board layouts for the 8-pin micro package.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for 3.3V or 5V systems. Consider the integrated watchdog timer if software robustness is critical. Verify that the 8-MSOP package fits the available PCB space. Compare against other SP706 variants if different voltage thresholds like 2.63V or 3.08V are needed instead.

Supervisors Part Context

This part belongs to the SP706 series of low-power microprocessor supervisory circuits. The series includes variants with different voltage thresholds such as the SP706REU-L (2.63V) and SP706TEU-L (3.08V). These components are designed to provide essential reset and monitoring functions for digital systems operating at low voltages.

Supervisors Replacement Considerations

Direct substitutes include the SP706SEN-L/TR and SP706TEN-L/TR from MaxLinear. Other compatible options are the MAX706SESA+ from Analog Devices and the DS1706SEUA from Maxim Integrated.
