SP708REN-L

Supervisors Overview

The SP708REN-L is a low-power microprocessor supervisory circuit manufactured by MaxLinear. It provides a reset signal with a threshold voltage of 4.4 V and features an active-high or active-low reset output. The device includes a manual reset input and a power-fail comparator but lacks a watchdog timer. It operates within a supply voltage range up to 5.5 V, with a reset delay time of 200 ms and accuracy of 4%. The component supports surface-mount installation in an 8-SOIC package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems
• Includes manual reset capability for system control
• Integrates a power-fail comparator for monitoring supply integrity

Supervisors Applications

• Microprocessor reset circuits
• Power supply monitoring systems
• Embedded controller supervision

Supervisors Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required reset polarity and threshold voltage for the target application design.

Supervisors Selection Notes

Select this component when a dedicated supervisor with manual reset and power-fail detection is required. Consider the 4.4 V threshold and 200 ms delay against system startup requirements. Verify that the 8-SOIC package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the SP708 series of low-power microprocessor supervisors from MaxLinear. The series typically offers various threshold voltages and output polarities to accommodate different logic families and supply rails in embedded designs.

Supervisors Replacement Considerations

Check for direct substitutes such as the SP708TEN-L/TR or SP708SEN-L/TR, which share the same family functionality but may differ in threshold voltage or packaging details.
