MCP6566/6R/6U/7/9
1.8V Low Power Open-Drain Output Comparator
Features
Description
• Propagation Delay at 1.8VDD
:
The Microchip Technology, Inc. MCP6566/6R/6U/7/9
families of Open-Drain output comparators are offered
in single, dual and quad configurations.
- 56 ns (typical) High to Low
• Low Quiescent Current: 100 µA (typical)
• Input Offset Voltage: ±3 mV (typical)
• Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V
• Open-Drain Output
These comparators are optimized for low power 1.8V,
single-supply applications with greater than rail-to-rail
input operation. The internal input hysteresis eliminates
output switching due to internal input noise voltage,
reducing current draw. The open-drain output of the
MCP6566/6R/6U/7/9 family requires a pull up resistor
and it supports pull-up voltages above and below VDD
which can be used to level shift. The output toggle
frequency can reach a typical of 4 MHz (typical) while
limiting supply current surges and dynamic power
consumption during switching.
• Wide Supply Voltage Range: 1.8V to 5.5V
• Available in Single, Dual, and Quad
• Packages: SC70, SOT-23-5, SOIC, MSOP,
TSSOP
Typical Applications
• Laptop computers
• Mobile Phones
This family operates with single supply voltage of 1.8V
to 5.5V while drawing less than 100 µA/comparator of
quiescent current (typical).
• Hand-held Electronics
• RC Timers
Package Types
• Alarm and Monitoring Circuits
• Window Comparators
• Multi-vibrators
