Frequently Asked Questions
At what supply voltage does MCP1319MT-46LE/OT assert its reset signal, and how is this threshold set?
The MCP1319MT-46LE/OT asserts its active-low RESET output when the monitored supply drops below the fixed 4.60 V threshold. This threshold is factory-trimmed and non-adjustable, eliminating the need for external resistor dividers and simplifying BOM in single-rail 5 V system designs.
Does MCP1319MT-46LE/OT support a manual reset function, and in which design scenarios is this useful?
Yes, the device includes a dedicated manual reset input (MR pin) that allows an external signal or pushbutton to force the RESET output low independent of supply voltage. This is valuable in factory test jigs, field-service reset scenarios, or watchdog-augmented designs requiring forced 1-pin resets.
How does the SOT-23-5 package of MCP1319MT-46LE/OT compare to larger supervisor packages in board space savings?
The SOT-23-5 package measures approximately 2.9 mm x 1.6 mm, consuming far less PCB area than 8-pin SOIC or DFN alternatives. For compact IoT nodes or wearable devices where board area is critical, this 5-pin package can save several square millimetres while delivering full voltage supervision functionality.
