Description

The MCP111/112 are voltage-detecting devices

designed to keep a microcontroller in reset until the

system voltage has stabilized at the appropriate level

for reliable system operation. These devices also

operate as protection from brown-out conditions when

the system supply voltage drops below the specified

threshold voltage level. Eight different trip voltages are

available.

MCP111/112 4.0 APPLICATION INFORMATION 4.1 For many of today’s microcontroller applications, care must be taken to prevent low-power conditions that can cause many different system problems. The most common causes are brown-out conditions, where the system supply drops below the operating level momentarily.
PAGE 12
MCP111/112 4.2 Negative Going VDD Transients The minimum pulse width (time) required to cause a reset may be an important criteria in the implementation of a Power-on Reset (POR) circuit. This time is referred to as transient duration, defined as the amount of time needed for these supervisory devices to respond to a drop in VDD. The transient duration time is dependant on the magnitude of VTRIP – VDD. Generally speaking, the transient duration decreases with increases in VTRIP – VDD.
