MCP6566/6R/6U/7/9
1.8V Low-Power Open-Drain Output Comparator
Features:
Description:
• Propagation Delay at 1.8 VDD
:
The Microchip MCP6566/6R/6U/7/9 family 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.
• Wide Supply Voltage Range: 1.8V to 5.5V
• Available in Single, Dual and Quad
• Packages: SC70, SOT-23-5, SOIC, MSOP, TSSOP
The open-drain output of the MCP6566/6R/6U/7/9 fam-
ily requires a pull-up resistor. It supports pull-up volt-
ages that are 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.
Typical Applications:
• Laptop Computers
• Mobile Phones
• Hand-held Electronics
• RC Timers
This family operates with single supply voltage of 1.8V
to 5.5V while drawing less than 100 µA/comparator of
quiescent current (typical).
• Alarm and Monitoring Circuits
• Window Comparators
• Multivibrators
