Typical Application
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.
