What are the key features of MCP111T-315E/MB?
- Fixed 3.08 V reset threshold voltage with active-low open-drain output for direct microcontroller reset line connection
- AEC-Q100 automotive-qualified (E-grade) voltage detector ensuring reliable operation across the full automotive temperature range
- Ultra-compact 4-pin SOT-89-3 package (3 pins + tab) enabling minimal footprint processor supervisors in space-constrained automotive ECUs
What is MCP111T-315E/MB used for?
The MCP111T-315E/MB is used in automotive electronic control units (ECUs) and body-control modules where a dedicated voltage supervisor monitors the 3.3 V supply rail and issues an active-low reset when voltage drops below 3.08 V during ignition transients or brownout events. It is also applied in industrial sensor nodes and motor-control boards that require a simple, BOM-efficient processor reset controller without watchdog or programmable delay features. The SOT-89 package's thermal tab aids heat dissipation in thermally demanding under-hood automotive environments.

Frequently Asked Questions
At what supply voltage does MCP111T-315E/MB trigger a reset, and what is the output type?
MCP111T-315E/MB monitors a fixed threshold of 3.08 V and asserts an active-low open-drain reset output whenever the supply falls below that level, allowing it to be directly wired to the reset pin of a 3.3 V microcontroller or DSP without any additional level-shifting components in automotive ECU designs.
Is MCP111T-315E/MB qualified for use in automotive under-hood environments?
Yes, the E-grade designation in MCP111T-315E/MB indicates AEC-Q100 automotive qualification for the extended temperature range, making it suitable for under-hood ECU applications where ambient temperatures may exceed 85°C and the 3.08 V reset threshold must remain accurate across harsh thermal and voltage transient conditions.
How does MCP111T-315E/MB reduce BOM complexity compared to a voltage supervisor with a watchdog timer?
MCP111T-315E/MB is a dedicated 1-channel voltage detector with no watchdog, no programmable reset delay, and no manual-reset pin, so it requires zero external timing components to produce a clean active-low reset at 3.08 V, reducing the bill of materials and PCB area compared to feature-rich supervisors in automotive and industrial designs where watchdog functionality is already handled in the MCU.
What is the lead time and package style for procuring MCP111T-315E/MB in production volumes?
MCP111T-315E/MB has a factory lead time of 8 weeks and is supplied in a 4-pin SOT-89-3 (3 pins + tab, JESD-30 code R-PSSO-F3) tape-and-reel format, which is compatible with automated SMT pick-and-place for automotive and industrial production runs requiring a compact 3.08 V processor supervisor.
