MCP102/103/121/131 - Microcontroller Supervisor Product Family Product Summary: Microchip's extensive family of low-cost, precision system supervisors allow the implementation of system reset circuits that protect the system from improper operation when the system voltage drops below a predetermined voltage level. The MCP102/103/121/131 family expands the choices available to the system designer by offering a wide range of output types, reset trip points and package options. These devices are functionally equivalent and pin-compatible with many industry standard supervisory products, offering easy migration to a lower power solution. Systems may need to take into account noisy environments and unreliable power sources, as well as the voltage decay of the system's battery. These issues may create a variety of system-level problems and can be eliminated by the use of a voltage supervisor device. Voltage supervisor devices are designed to output a signal that can be used as a system reset signal. Therefore, when the system voltage is below the operating range, the system is in reset. Once the voltage returns to the valid operating range, the voltage supervisor does not force a system reset. This allows the system supervisor to provide protection from system brown-outs, noisy power systems and decaying power supplies (such as battery applications and power loss).
