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.
