What are the key features of MCP39F501-E/MQ?
- Dual-channel voltage supervision with adjustable threshold on each channel, supporting simultaneous monitoring of 2 independent supply rails
- 28-pin QFN package (5 mm x 5 mm typical) enabling compact layout for dense multi-rail power sequencing designs
- Pb-free JEDEC e3 compliant construction with 5-week factory lead time and 13-year YTEOL for long lifecycle industrial programs
What is MCP39F501-E/MQ used for?
MCP39F501-E/MQ is used in multi-rail embedded systems where independent voltage supervisors must assert reset or interrupt signals when any supply rail falls outside its adjustable threshold window. It suits industrial PLCs, server power modules, and communication equipment needing reliable startup sequencing and brownout detection across 2 voltage rails simultaneously. The adjustable threshold feature allows one part to cover multiple product variants with different core and I/O supply voltages.

Frequently Asked Questions
How many voltage rails can MCP39F501-E/MQ monitor simultaneously, and are the thresholds fixed or adjustable?
MCP39F501-E/MQ monitors 2 independent voltage rails simultaneously, with adjustable threshold levels on each channel. This allows a single IC to supervise, for example, a 3.3 V core rail and a 1.8 V I/O rail with independently set undervoltage trip points, reducing the need for 2 separate single-channel supervisor ICs and their associated resistor dividers.
What QFN package does MCP39F501-E/MQ use, and how does it fit in a compact multi-rail power management PCB?
MCP39F501-E/MQ is housed in a 28-pin QFN package (JEDEC S-PQCC-N28) with an exposed thermal pad and 0.5 mm pitch, typically measuring 5 mm x 5 mm. In a multi-rail power management board, this compact footprint allows placement within a 6 mm x 6 mm keep-out zone near the power input stage, leaving room for bulk capacitors and reset output pull-up resistors.
For a 13-year product lifecycle industrial controller, why is MCP39F501-E/MQ a reliable voltage supervisor choice?
MCP39F501-E/MQ has a YTEOL (years to end of life) rating of 13, meaning Microchip commits to manufacturing availability through at least 2039. For industrial control programs requiring a single board revision over a decade, this lifecycle commitment reduces costly redesigns. Its 5-week factory lead time and standard QFN-28 sourcing also support stable procurement planning for annual build volumes of 10,000 units or more.
