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.

MCP65R41/6 4.0 APPLICATIONS INFORMATION The MCP65R41/6 family of push-pull and open-drain output comparators are fabricated on Microchip’s stateof-the-art CMOS process. They are suitable for a wide range of high-speed applications requiring low power consumption. 4.1 Comparator Inputs 4.1.1 NORMAL OPERATION The input stage of this family of devices uses three differential input stages in parallel: one operates at low input voltages, one at high input voltages, and one at mid input voltages.
PAGE 22
MCP65R41/6 4.2 VDD D1 VPU RPU* V1 + R1 VOUT – D2 Push-Pull Output The push-pull output is designed to be compatible with CMOS and TTL logic, while the output transistors are configured to give a rail-to-rail output performance. They are driven with circuitry that minimizes any switching current (shoot-through current from supply to supply) when the output is transitioned from high-tolow, or from low-to-high (see Figures 2-18 and 2-19 for more information).

MCP65R41/6 4.3.1 4.3.2 NON-INVERTING CIRCUIT Figure 4-4 shows a non-inverting circuit for singlesupply applications using just two resistors. The resulting hysteresis diagram is shown in Figure 4-5.

MCP65R41/6 To determine the trip voltages (VTLH and VTHL) for the circuit shown in Figure 4-6, R2 and R3 can be simplified to the Thevenin equivalent circuit with respect to VREF, as shown in Figure 4-8: VPU VDD VOUT + VSS V23 R23 Where: RF R 2 R3 R 23 = -------------------R2 + R3 V 23 R3 = --------------------  VREF R2 + R3 * Pull-up resistor required for the MCP65R46 only.

PAGE 25
MCP65R41/6 4.6 PCB Surface Leakage 4.7 In applications where the low input bias current is critical, the Printed Circuit Board (PCB) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other type of contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 1012. A 5V difference would cause 5 pA of current to flow. This is greater than the MCP65R41/6 family’s bias current at +25°C (1 pA, typical).
PAGE 26
MCP65R41/6 4.7.3 OVER-TEMPERATURE PROTECTION CIRCUIT The MCP65R41 device can be used as an overtemperature protection circuit using a thermistor. The 2.4V VREF can be used as stable reference to the thermistor, the alert threshold and hysteresis threshold. This is ideal for battery powered applications, where the change in temperature and output toggle thresholds would remain fixed as battery voltage decays over time.
