| MCP6561/1R/1U/2/4 1.8V Low Power Push-Pull Output Comparator Features * Propagation Delay at 1.8VDD: - 56 ns (typical) High to Low - 49 ns (typical) Low to High * Low Quiescent Current: 100 A (typical) * Input Offset Voltage: 3 mV (typical) * Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V * CMOS/TTL Compatible Output * Wide Supply Voltage Range: 1.8V to 5.5V * Available in Single, Dual, and Quad * Packages: SC70-5, SOT-23-5, SOIC, MSOP, TSSOP Description The Microchip Technology, Inc. MCP6561/1R/1U/2/4 families of CMOS/TTL compatible comparators are offered in single, dual, and quad configurations. These comparators are optimized for low power 1.8V, single-supply applications with greater than rail-to-rail input operation. The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The push-pull output of the MCP6561/1R/1U/2/4 family supports rail-to-rail output swing, and interfaces with CMOS/TTL logic. The output toggle frequency can reach a typical of 4 MHz (typical) while limiting supply current surges and dynamic power consumption during switching. This family operates with single supply voltage of 1.8V to 5.5V while drawing less than 100 A/comparator of quiescent current (typical).

For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts are used in a single (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need a local bypass capacitor (typically 0.01 F to 0.1 F) within 2 mm of the VDD pin. These can share a bulk capacitor with nearby analog parts (within 100 mm), but it is not required. The comparator outputs are CMOS, push-pull digital outputs. They are designed to be compatible with CMOS and TTL logic and are capable of driving heavy DC or capacitive loads. (c) 2009 Microchip Technology Inc.

MCP6561/1R/1U/2/4 4.0 APPLICATIONS INFORMATION 4.1.2 The MCP6561/1R/1U/2/4 family of push-pull output comparators are fabricated on Microchip's state-of-theart CMOS process. They are suitable for a wide range of high speed applications requiring low power consumption. INPUT VOLTAGE AND CURRENT LIMITS 4.1 4.1.1 Comparator Inputs NORMAL OPERATION The ESD protection on the inputs can be depicted as shown in Figure 4-2. This structure was chosen to protect the input transistors, and to minimize input bias current (IB). The input ESD diodes clamp the inputs when they try to go more than one diode drop below VSS. They also clamp any voltages that go too far above VDD; their breakdown voltage is high enough to allow normal operation, and low enough to bypass ESD events within the specified limits. VDD Bond Pad 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 voltage. With this topology, the input voltage range is 0.3V above VDD and 0.3V below VSS, while providing low offset voltage through out the common mode range. The input offset voltage is measured at both VSS - 0.3V and VDD + 0.3V to ensure proper operation. The MCP6561/1R/1U/2/4 family has internally-set hysteresis VHYST that is small enough to maintain input offset accuracy and large enough to eliminate output chattering caused by the comparator's own input noise voltage ENI. Figure 4-1 depicts this behavior. Input offset voltage (VOS) is the center (average) of the (input-referred) low-high and high-low trip points. Input hysteresis voltage (VHYST) is the difference between the same trip points. VIN+ Bond Pad Input Stage Bond Pad VIN- VSS Bond Pad FIGURE 4-2: Structures.

Figure 4-3 shows the recommended approach to protecting these inputs. The internal ESD diodes prevent the input pins (VIN+ and VIN-) from going too far below ground, and the resistors R1 and R2 limit the possible current drawn out of the input pin. Diodes D1 and D2 prevent the input pin (VIN+ and VIN-) from going too far above VDD. When implemented as shown, resistors R1 and R2 also limit the current through D1 and D2. VDD D1 V1 R1 D2 V2 R2 R1 R2 R3 + MCP656X - VOUT Output Voltage (V) Time (100 ms/div) FIGURE 4-1: The MCP6561/1R/1U/2/4 comparators' internal hysteresis eliminates output chatter caused by input noise voltage.

Protecting the Analog DS22139B-page 15 MCP6561/1R/1U/2/4 It is also possible to connect the diodes to the left of the resistors R1 and R2. In this case, the currents through the diodes D1 and D2 need to be limited by some other mechanism. The resistor then serves as in-rush current limiter; the DC current into the input pins (VIN+ and VIN-) should be very small. A significant amount of current can flow out of the inputs when the common mode voltage (VCM) is below ground (VSS); see Figure 2-32. Applications that are high impedance may need to limit the usable voltage range. 4.3.1 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. VDD VREF MCP656X + VIN R1 RF VOUT 4.1.3 PHASE REVERSAL The MCP6561/1R/1U/2/4 comparator family uses CMOS transistors at the input. They are designed to prevent phase inversion when the input pins exceed the supply voltages. Figure 2-3 shows an input voltage exceeding both supplies with no resulting phase inversion. FIGURE 4-4: Non-Inverting Circuit with Hysteresis for Single-Supply. VOUT VDD VOH High-to-Low VOL VSS VSS Low-to-High VIN VTHL VTLH VDD 4.2 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 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-to-low, or from low-to-high (see Figure 2-15 and Figure 2-18 for more information). 4.3 Externally Set Hysteresis Greater flexibility in selecting hysteresis (or input trip points) is achieved by using external resistors. Hysteresis reduces output chattering when one input is slowly moving past the other. It also helps in systems where it is best not to cycle between high and low states too frequently (e.g., air conditioner thermostatic control). Output chatter also increases the dynamic supply current. FIGURE 4-5: Hysteresis Diagram for the Non-Inverting Circuit. The trip points for Figure 4-4 and Figure 4-5 are: EQUATION 4-1: R1 R 1 V TLH = V REF 1 + ------ - V OL ------ RF R F R1 R1 V THL = V REF 1 + ------ - V OH ------ RF R F Where: VTLH VTHL = = trip voltage from low to high trip voltage from high to low DS22139B-page 16 (c) 2009 Microchip Technology Inc.

FIGURE 4-7: Inverting Circuit. Hysteresis Diagram for the 4.5 Capacitive Loads In order to determine the trip voltages (VTHL and VTLH) for the circuit shown in Figure 4-6, R2 and R3 can be simplified to the Thevenin equivalent circuit with respect to VDD, as shown in Figure 4-8. VDD MCP656X + V23 R23 RF VSS VOUT Reasonable capacitive loads (e.g., logic gates) have little impact on propagation delay (see Figure 2-31). The supply current increases with increasing toggle frequency (Figure 2-19), especially with higher capacitive loads. The output slew rate and propagation delay performance will be reduced with higher capacitive loads. FIGURE 4-8: Thevenin Equivalent Circuit. (c) 2009 Microchip Technology Inc. DS22139B-page 17 MCP6561/1R/1U/2/4 4.6 PCB Surface Leakage 4.7 PCB Layout Technique In applications where low input bias current is critical, PCB (Printed Circuit Board) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other 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 MCP6561/1R/1U/2/4 family's bias current at +25C (1 pA, typical). The easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin. An example of this type of layout is shown in Figure 4-9. ININ+ VSS When designing the PCB layout it is critical to note that analog and digital signal traces are adequately separated to prevent signal coupling. If the comparator output trace is at close proximity to the input traces then large output voltage changes from, VSS to VDD or visa versa, may couple to the inputs and cause the device output to oscillate. To prevent such oscillation, the output traces must be routed away from the input pins. The SC70-5 and SOT-23-5 are relatively immune because the output pin OUT (pin 1) is separated by the power pin VDD/VSS (pin 2) from the input pin +IN (as long as the analog and digital traces remain separated through out the PCB). However, the pinouts for the dual and quad packages (SOIC, MSOP, TSSOP) have OUT and -IN pins (pin 1 and 2) close to each other. The recommended layout for these packages is shown in Figure 4-10. OUTA -INA +INA Guard Ring VSS VDD OUTB -INB +INB FIGURE 4-9: Example Guard Ring Layout for Inverting Circuit. 1. Inverting Configuration (Figures 4-6 and 4-9): a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the comparator (e.g., VDD/2 or ground). b) Connect the inverting pin (VIN-) to the input pad without touching the guard ring. Non-inverting Configuration (Figure 4-4): a) Connect the non-inverting pin (VIN+) to the input pad without touching the guard ring. b) Connect the guard ring to the inverting input pin (VIN-). FIGURE 4-10: Recommended Layout. 4.8 Unused Comparators 2. An unused amplifier in a quad package (MCP6564) should be configured as shown in Figure 4-11. This circuit prevents the output from toggling and causing crosstalk. It uses the minimum number of components and draws minimal current (see Figure 2-15 and Figure 2-18). 1/4 MCP6564 VDD - + FIGURE 4-11: Unused Comparators.

An easy way to solve this problem is to use an amplifier (such as the MCP6291) to gain-up the input signal before it reaches the comparator. Figure 4-12 shows an example of this approach. VDD VREF MCP6291 VDD VIN R1 R2 VREF MCP656X VOUT A simple bistable multi-vibrator design is shown in Figure 4-14.
