MCP6546/7/8/9

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 碌A/

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.
