MCP6541/1R/1U/2/3/4

Push-Pull Output Sub-Microamp Comparators

Description:

Features:

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

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

• CMOS/TTL-Compatible Output

The Microchip Technology Inc. MCP6541/1R/1U/2/3/4

family of comparators is offered in single (MCP6541,

MCP6541R, MCP6541U), single with Chip Select (CS)

(MCP6543), dual (MCP6542) and quad (MCP6544)

configurations. The outputs are push-pull (CMOS/TTL-

compatible) and are capable of driving heavy DC or

capacitive loads.

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

• Wide Supply Voltage Range: 1.6V to 5.5V

• Available in Single, Dual and Quad

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

• Chip Select (CS) with MCP6543

• Low Switching Current

These comparators are optimized for low-power,

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

input operation. The push-pull output of the MCP6541/

1R/1U/2/3/4 family supports rail-to-rail output swing

and interfaces with TTL/CMOS logic. The internal input

hysteresis eliminates output switching due to internal

input noise voltage, reducing current draw. The output

limits supply current surges and dynamic power

consumption while switching. This product family

operates with a single-supply voltage as low as 1.6V

and draws less than 1 µA/comparator of quiescent

current.

• Internal Hysteresis: 3.3 mV (typ.)

• Temperature Ranges:

- Industrial: -40°C to +85°C

- Extended: -40°C to +125°C

Typical Applications:

• Laptop Computers

• Mobile Phones

The related MCP6546/7/8/9 family of comparators from

Microchip has an open-drain output. Used with a pull-

up resistor, these devices can be used as level-shifters

for any desired voltage up to 10V and in wired-OR

logic.

• Metering Systems

• Hand-held Electronics

• RC Timers

• Alarm and Monitoring Circuits

• Windowed Comparators

• Multi-vibrators

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

the data sheet.

MCP6541U SOT-23-5 is E-Temp only.
