Description

The Microchip Technology Inc. MCP6546/6R/6U/7/8/9

family of comparators is offered in single (MCP6546,

MCP6546R, MCP6546U), single with chip select (CS)

(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 MCP6546/6R/6U/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 switch-

ing due to internal noise voltage, reducing current draw.

These comparators operate with a single-supply

voltage as low as 1.6V and draw a quiescent current of

less than 1 µA/comparator.

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.
