Description

The Microchip MCP6546/6R/6U/7/8/9 family of com-

parators, 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 Microchip MCP6541/2/3/4 family of com-

parators has a push-pull output that supports rail-to-rail

output swing and interfaces with CMOS/TTL logic.

Note that SC-70-5 E-Temp parts are not available at

this release of the data sheet.

The MCP6546U SOT-23-5 is E-Temp only.
