Description
The Microchip Technology Inc. MCP6546/7/8/9 family
of comparators is offered in single (MCP6546), single
with chip select (MCP6548), dual (MCP6547) and quad
(MCP6549) configurations. The outputs are open-drain
and are capable of driving heavy DC or capacitive
loads.
These comparators are optimized for low power,
single-supply application with greater than rail-to-rail
input operation. The output limits supply current surges
and dynamic power consumption while switching. The
open-drain output of the MCP6546/7/8/9 family can be
used as a level-shifter for up to 10V using a pull-up
resistor. It can also be used as a wired-OR logic. The
internal Input hysteresis eliminates output switching
due to internal noise voltage, reducing current draw.
These comparators operate with a single-supply
voltage as low as 1.6V and draw less than 1 µA/
comparator of quiescent current.
The related MCP6541/2/3/4 family of comparators from
Microchip has a push-pull output that supports rail-to-
rail output swing and interfaces with CMOS/TTL logic.
