MCP65R41/6

3 µA Comparator with Integrated Reference Voltage

Features

Description

• Factory Set Reference Voltage

- Available Voltage: 1.21V and 2.4V

- Tolerance: ±1% (typical)

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.

• Low Quiescent Current: 2.5 µA (typical)

• Propagation Delay: 4 µs with 100 mV overdrive

• Input Offset Voltage: ±3mV (typical)

• Rail-to-Rail Input: V_SS- 0.3V to V_DD+ 0.3V

• Output Options:

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.
