SP6415ER-L/TR

Overview

The SP6415ER-L/TR is a dual-supply supervisor IC manufactured by Sipex. It monitors two independent voltage rails and provides reset signals when inputs fall below specified thresholds. The device features an open-drain or push-pull reset output, a manual reset input, and a watchdog timer with a timeout period of approximately 280ms. It operates within a supply voltage range of 1.7V to 5.5V and includes a power-on reset circuit. The component is housed in an 8-pin SOIC package.

Feature Summary

• Dual-channel voltage monitoring for independent power rails
• Integrated watchdog timer with automatic timeout reset
• Manual reset input capability for system control
• Low quiescent current consumption

Applications

• Portable electronic devices requiring dual power domains
• Embedded systems with microcontroller supervision needs
• Battery-powered equipment with low-power constraints
• Industrial control modules requiring reliable reset sequencing

Procurement Notes

Verify the specific suffix configuration against official Sipex documentation to ensure correct output drive type and threshold settings. Confirm RoHS compliance status if required for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any recent obsolescence notices from Exar or its successors.

Selection Notes

Select this component when dual-voltage supervision is required in a compact footprint. Ensure the monitored voltages fall within the operational range of the device. Consider the watchdog timer requirements for your application's fault detection strategy. Verify that the package size fits your PCB layout constraints compared to alternative supervisor ICs.

Part Context

This part belongs to the Sipex/Exar family of power management supervisors. These devices are designed to enhance system reliability by monitoring critical power supplies. The series typically includes variants with different reset delays and output configurations. Sipex was acquired by Exar, which later became part of Renesas Electronics.

Replacement Considerations

Check for direct pin-compatible alternatives from Renesas or other manufacturers offering dual-supervisor ICs. Verify that replacement parts match the voltage thresholds and watchdog timeout specifications. Ensure the replacement supports the same package type and operating temperature range.
