What are the key features of MCP1317T-46LE/OT?
- Fixed 4.60 V undervoltage threshold with active-high reset output eliminating external comparator or resistor divider components
- Manual reset input pin allowing external push-button or logic-controlled system reset in 5-pin SOT-23 package
- Single-channel design in compact SOT-23-5 footprint for cost-effective processor reset in space-constrained embedded systems
What is MCP1317T-46LE/OT used for?
The MCP1317T-46LE/OT is used in microcontroller and DSP reset circuits where a reliable power-on reset and undervoltage lockout at 4.60 V is required. Its active-high reset output directly drives the reset pin of processors without additional logic inversion, simplifying circuit design in industrial controllers and communication equipment. The manual reset input supports panel-mounted reset buttons in embedded systems operating from regulated 5 V supplies.

Frequently Asked Questions
What is the fixed threshold voltage of the MCP1317T-46LE/OT and what type of reset output does it provide?
The MCP1317T-46LE/OT has a fixed undervoltage detection threshold of 4.60 V and provides an active-high reset output. When the monitored supply drops below 4.60 V, the output asserts high, holding the connected processor in reset until the supply recovers and the internal reset timeout elapses, ensuring reliable startup in 5 V embedded systems.
How does the manual reset input on MCP1317T-46LE/OT improve system controllability in embedded designs?
The manual reset input pin on MCP1317T-46LE/OT allows an external signal — such as a push-button connected through a debounce circuit or a supervisory GPIO — to force a system reset independently of the 4.60 V undervoltage threshold. This is useful in industrial embedded systems with front-panel reset buttons, where a hardware-initiated reset is needed without power cycling the 5 V supply rail.
When is MCP1317T-46LE/OT a compact alternative to discrete voltage supervisor circuits for 5 V systems?
MCP1317T-46LE/OT integrates 1-channel voltage monitoring, 4.60 V threshold detection, active-high output, and a manual reset input in a single 5-pin SOT-23 device — replacing a voltage divider, comparator, RC delay, and open-drain output stage. At under 3 mm × 1.75 mm footprint, it reduces BOM by 4 or more components while delivering a calibrated 4.60 V reset threshold suited to regulated 5 V rail supervision.
