Microcontroller Supervisor Family Product Information The Microchip family of low-cost, precision system supervisors supports microcontrollers, ASICs, digital signal processors and custom chip sets. The family offers a large variety of reset trip points, output types and package options to cover most application requirements. Also, the breadth of the product line enables Microchip supervisors to cross to virtually all competitors supervisory reset products. The devices are functionally and pinout comparable to products from other analog suppliers. Noisy environments, unreliable power or battery power in many microcontroller applications may create a variety of system-level problems that can be eliminated with power-on reset or brown-out detect functions found on the supervisors. The power-on reset devices are designed to hold the microcontroller in reset until the supply voltage reaches a predetermined operating level and stabilizes. This supervisor family protects from brown-out conditions occurring as a result of supply voltage drops below the safe operating level. It eliminates a slowly decaying power supply which causes the microcontroller to begin executing instructions without enough voltage to sustain its SRAM, producing indeterminate results, and helps prevent a runaway system or helps back up critical data during power fluctuations. Microchip offers supervisors in 3-pin SOT-23, TO-92, 4-pin SOT143, 8-pin PDIP and 8/16-pin SOIC packages in various pin configurations. It is ideal for embedded control applications such as hand-held instrumentation, telephone hand sets and other battery powered operations.
