What are the key features of MCP1316T-46KE/OT?
- 4.6 V factory-set trip threshold with active-low push-pull reset output for direct MCU interface without external pull-up resistors
- Integrated 1600 ms watchdog timer with dedicated WDI input catches firmware lockups and forces a system reset automatically
- 1.6 ms reset delay in a compact 5-pin SOT-23 package minimizes board space while meeting IEC 60730 supervisory timing requirements
What is MCP1316T-46KE/OT used for?
The MCP1316T-46KE/OT is used in microcontroller-based systems operating from a 5 V rail that require reliable power-on reset, undervoltage detection at 4.6 V, and watchdog supervision of firmware execution. It is well suited for industrial control modules, home appliance controllers, and automotive accessory boards where a compact SOT-23 supervisor with manual reset and watchdog in a single device reduces component count. The push-pull reset output drives MCU reset pins directly without additional pull-up resistors, simplifying PCB design.

Frequently Asked Questions
What reset threshold voltage and watchdog timeout does the MCP1316T-46KE/OT provide?
The MCP1316T-46KE/OT has a fixed trip threshold of 4.6 V and a watchdog timeout of 1600 ms. When the supply drops below 4.6 V, the active-low reset output asserts within the response time. If the WDI input is not toggled within 1600 ms, the watchdog forces a reset pulse with a 1.6 ms reset delay before the MCU restarts.
Which MCU supply voltage range is compatible with MCP1316T-46KE/OT supervision?
The MCP1316T-46KE/OT monitors a nominal 5 V supply rail with a 4.6 V trip threshold. It operates across a supply range from approximately 1 V up to 5.5 V, making it compatible with 5 V microcontrollers such as 8-bit AVR and PIC devices that require undervoltage reset protection during brown-out events.
How does the push-pull reset output of MCP1316T-46KE/OT simplify PCB design compared to open-drain alternatives?
The push-pull reset output actively drives both logic-high and logic-low levels, eliminating the need for an external pull-up resistor typically required with open-drain reset supervisors. This reduces the BOM by at least 1 component per supervisor instance and ensures fast rise times on the reset line even when the MCU reset pin has significant capacitance, typically achieving sub-microsecond transitions.
In which compact form factor does the MCP1316T-46KE/OT ship, and how much board space does it require?
The MCP1316T-46KE/OT ships in a 5-pin SOT-23 package, which measures approximately 2.9 mm x 1.6 mm with a typical footprint area under 10 mm². This makes it one of the smallest voltage supervisor options for space-constrained designs such as wearable devices, IoT sensors, and compact embedded modules that cannot accommodate larger 8-pin SOIC packages.
