MCP6546/6R/6U/7/8/9

Open-Drain Output Sub-Microamp Comparators

Features

Description

• Low Quiescent Current: 600 nA/comparator (typ.)

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

• Open-Drain Output: V_OUT≤ 10V

• Propagation Delay: 4 µs (typ., 100 mV Overdrive)

• Wide Supply Voltage Range: 1.6V to 5.5V

• Single available in SOT-23-5, SC-70-5 * packages

• Available in Single, Dual and Quad

• Chip Select (CS) with MCP6548

• Low Switching Current

The Microchip Technology Inc. MCP6546/7/8/9 family

of comparators is offered in single (MCP6546,

MCP6546R, MCP6546U), 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 a quiescent current of

less than 1 µA/comparator.

• Internal Hysteresis: 3.3 mV (typ.)

• Temperature Range:

- Industrial: -40°C to +85°C

- Extended: -40°C to +125°C

Typical Applications

• Laptop Computers

• Mobile Phones

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.

• Metering Systems

• Hand-held Electronics

• RC Timers

* SC-70-5 E-Temp parts not avaliable at this release of

the data sheet.

• Alarm and Monitoring Circuits

• Windowed Comparators

• Multi-vibrators

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