What are the key features of MCP100-315DI/TO?
- Fixed 3.15 V reset threshold with ±2% accuracy, eliminating the need for external resistor dividers in 3.3 V supply monitoring
- 140 ms reset timeout delay ensures stable power-up sequencing for microcontrollers and logic ICs
- Active-low open-drain reset output directly drives standard microprocessor reset pins without additional level shifting
- 3-pin TO-92 through-hole package supports manual assembly and prototype builds with minimal PCB footprint
What is MCP100-315DI/TO used for?
MCP100-315DI/TO is used to generate reliable power-on reset signals for microcontrollers, FPGAs, and DSPs operating from 3.3 V rails, preventing code execution before supply voltage stabilizes. It is commonly found in industrial controllers, motor drives, and embedded computing boards where brown-out protection during supply fluctuations is essential. Consumer electronics products such as smart home hubs and handheld instruments also use it to supervise the main MCU supply rail.

Frequently Asked Questions
At what supply voltage does MCP100-315DI/TO assert its reset output, and how accurate is that threshold?
MCP100-315DI/TO asserts its active-low reset output when the monitored supply falls below 3.15 V, with a threshold accuracy of ±2%. This precision is sufficient to distinguish normal 3.3 V rail operation from a genuine brown-out condition without requiring external resistors or trimming.
How long does MCP100-315DI/TO hold the reset signal after the supply rises above the threshold?
After the supply voltage rises above the 3.15 V threshold, the MCP100-315DI/TO maintains the reset output active for a fixed 140 ms timeout period. This delay allows oscillators, PLLs, and memory devices to stabilize before the microprocessor begins executing code, preventing spurious start-up behaviour.
Which circuit boards benefit most from using MCP100-315DI/TO instead of a discrete RC reset circuit?
Any 3.3 V microcontroller board that requires a predictable 140 ms power-on delay benefits from MCP100-315DI/TO over an RC network, because the IC maintains a consistent ±2% threshold over -40°C to 85°C while an RC circuit drifts with temperature and component tolerance. Industrial PLCs, data loggers, and IoT gateway boards are common targets.
What is the operating temperature range of MCP100-315DI/TO and what does the 'I' suffix indicate?
The 'I' suffix in MCP100-315DI/TO denotes the industrial temperature grade, covering -40°C to 85°C operation. The TO-92-3 through-hole package handles those extremes without derating, making it a cost-effective choice for equipment deployed in outdoor cabinets, factory floors, and unheated enclosures.
