SP690TCN-L

Supervisors Overview

The SP690TCN-L is a voltage supervisory circuit manufactured by MaxLinear, Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 4.75 V to 5.5 V. Key electrical parameters include an under-voltage threshold of 4.525 V and an over-voltage threshold of 4.775 V. The device features an active low, open-drain output with a manual reset capability and a watchdog timer. It has a reset delay time of 200 ms and consumes 35 uA of operating current. The component is housed in an SOIC-Narrow-8 package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates under-voltage and over-voltage detection for comprehensive power rail supervision
• Includes a manual reset input and a watchdog timer for system reliability
• Provides an active low, open-drain output signal compatible with standard logic interfaces

Supervisors Applications

• Microprocessor power supply monitoring
• Battery backup switching circuits
• Industrial control system power management

Supervisors Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and design specifications. Check for RoHS compliance details as required by project regulations. Evaluate alternative components if long-term supply stability is a critical requirement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both under-voltage and over-voltage protection is required. The manual reset feature allows for user-initiated recovery, while the watchdog timer adds automated fault handling. Consider the 35 uA quiescent current for low-power applications. Verify that the SOIC-Narrow-8 package fits the mechanical constraints of the design.
