MP111-195E/LB

Manufacturer Part Number
MP111-195E/LB
Description
Micropower Voltage Detector
Manufacturer
MICROCHIP [Microchip Technology]
Datasheet
Features
• Ultra-low supply current: 1.75 µA (max.)
• Precision monitoring options of:
• Resets microcontroller in a power-loss event
• Active-low V
• Available in SOT23-3, TO-92, SC-70 and
• Temperature Range:
• Pb-free devices
Applications
• Critical Microcontroller and Microprocessor
• Computers
• Intelligent Instruments
• Portable Battery-Powered Equipment
Description
The
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.
