Description:

The Microchip Technology Inc. MCP65R41/6 family of

push-pull and open-drain output comparators are

offered with integrated reference voltages of 1.21V and

2.4V. This family provides ±1 (typical) tolerance while

consuming 2.5 μA (typical) current. These comparators

operate with a single-supply voltage as low as 1.8V to

5.5V, which makes them ideal for low cost and/or

battery powered applications.

These comparators are optimized for low-power,

single-supply applications with greater than rail-to-rail

input operation. The output limits supply current surges

and dynamic power consumption while switching. The

internal input hysteresis eliminates output switching

due to internal noise voltage, reducing current draw.

The MCP65R41 output interfaces to CMOS/TTL logic.

The open-drain output device MCP65R46 can be used

as a level-shifter from 1.6V to 10V using a pull-up

resistor. It can also be used as a wired-OR logic.

This family of devices is available in the 6-lead SOT-23 package.
