MCP1316T-46FE/OT

Supervisors Overview

The MCP1316T-46FE/OT is a supervisory circuit designed to monitor system voltage and maintain a microcontroller in reset until power stabilizes. It features an active low push-pull output with a fixed threshold of 4.6V. The device operates within a supply voltage range of 1V to 5.5V, drawing a typical operating current of 10μA. It includes built-in hysteresis (typically 50mV) to prevent oscillation during slow or noisy voltage ramps. The component is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Active low push-pull output driver for direct interface with digital logic
• Built-in hysteresis prevents output oscillation during slow or noisy voltage transitions
• Low quiescent current consumption suitable for battery-powered applications
• Fixed voltage threshold ensures reliable reset generation at specified levels

Supervisors Applications

• Microcontroller power-on reset circuits
• Battery-operated electronic devices requiring voltage monitoring
• Portable equipment with limited power budgets
• Industrial control systems needing stable power supervision

Supervisors Procurement Notes

Verify the specific suffix '46FE' confirms the 4.6V threshold and LSSOP/SOT-23-5 packaging variant. Confirm RoHS compliance status as lead-free. Ensure the ordering code matches the exact manufacturer part number to avoid functional mismatches in threshold voltage or output configuration.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for system supervision. The active low push-pull output simplifies interface design compared to open-drain variants. Consider the low 10μA operating current for energy-sensitive designs. Verify that the SOT-23-5 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the Microchip MCP1316 series of supervisory circuits. The series offers various threshold voltages and output configurations to suit different system requirements. The MCP1316T-46FE/OT specifically targets applications needing a 4.6V trip point with robust noise immunity provided by internal hysteresis.

Supervisors Replacement Considerations

Compatible substitutes include other MCP1316 variants with similar thresholds or output types, such as MCP1316T-46LE/OT for open-drain output. Cross-reference datasheets for pin compatibility and electrical specifications before substitution.
