MCP13xx System Supervisors and Reset Circuits

Microchip MCP13xx System Supervisors and Reset Circuits are an extensive family of low-cost, precision system supervisors. These system supervisors and reset circuits support microcontrollers, ASICs, digital signal processors, and custom chipsets. The family offers a large variety of reset trip points, output types, and package options to cover most application requirements. The supervisor family protects from brown-out conditions occurring as a result of supply voltage drops below the safe operating level. The devices are ideal for embedded control applications such as hand-held instrumentation, telephone hand-sets, and other battery-powered operations.
