Microcontroller Supervisor Family

Product Summary

Microchip’s extensive family of low-cost, precision system

supervisors and reset circuits support 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.

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

ﬂ uctuations.

Microchip offers supervisors in 3-pin SC-70, 3/5-pin

SOT-23, TO-92, 4-pin SOT-143, 8-pin PDIP and 8/16-pin

SOIC packages in various pin conﬁ gurations. It is ideal

for embedded control applications such as hand-held

instrumentation, telephone hand sets and other battery

powered operations.
