MCP6546/6R/6U/7/8/9 Open-Drain Output Sub-Microamp Comparators Features Description • Low Quiescent Current: 600 nA/Comparator (typical) • Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V The Microchip Technology Inc. MCP6546/6R/6U/7/8/9 family of comparators, is offered in single (MCP6546, MCP6546R, MCP6546U), single with chip select (CS) (MCP6548), dual (MCP6547) and quad (MCP6549) configurations. The outputs are open-drain and are capable of driving heavy DC or capacitive loads. • • • • • • • • • Open-Drain Output: VOUT ≤ 10V Propagation Delay: 4 µs (typical, 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 Internal Hysteresis: 3.3 mV (typical) Temperature Range: - Industrial: -40°C to +85°C - Extended: -40°C to +125°C Typical Applications • • • • • • • • Laptop Computers Mobile Phones Metering Systems Hand-held Electronics RC Timers Alarm and Monitoring Circuits Windowed Comparators Multi-vibrators 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 MCP6546/6R/6U/7/8/9 family can be used as a level-shifter for up to 10V using a pullup 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. The related MCP6541/2/3/4 family of comparators from Microchip has a push-pull output that supports rail-torail output swing and interfaces with CMOS/TTL logic. * SC-70-5 E-Temp parts are not available at this release of the data sheet. MCP6546U SOT-23-5 is E-Temp only.

They are designed to make level shifting and wired-OR easy to implement. © 2002-2012 Microchip Technology Inc. 3.4 Negative Power Supply Power Supply (VSS and VDD) The positive power supply pin (VDD) is 1.6V to 5.5V higher than the negative power supply pin (VSS). For normal operation, the other pins are at voltages between VSS and VDD, except the output pins which can be as high as 10V above VSS. 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 µF to 0.1 µF) 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.

MCP6546/6R/6U/7/8/9 4.0 APPLICATIONS INFORMATION The MCP6546/6R/6U/7/8/9 family of push-pull output comparators are fabricated on Microchip’s state-of-theart CMOS process. They are suitable for a wide range of applications requiring very low power consumption. 4.1 VDD D1 V1 Comparator Inputs 4.1.1 INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-1. 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 Input Stage Bond Pad VIN– VSS Bond Pad FIGURE 4-1: Structures. Simplified Analog Input ESD In order to prevent damage and/or improper operation of these amplifiers, the circuits they are in must limit the currents (and voltages) at the VIN+ and VIN– pins (see Absolute Maximum Ratings † at the beginning of Section 1.0 “Electrical Characteristics”). 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. © 2002-2012 Microchip Technology Inc. – VOUT V2 R2 R3 R1 ≥ VSS – (minimum expected V1) 2 mA R2 ≥ VSS – (minimum expected V2) 2 mA FIGURE 4-2: Inputs. Protecting the Analog It is also possible to connect the diodes to the left of resistors R1 and R2. In this case, the currents through 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 2-42. Applications that are high impedance may need to limit the usable voltage range. 4.1.3 VIN+ Bond Pad MCP6G0X D2 PHASE REVERSAL The MCP6546/6R/6U/7/8/9 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. 4.1.2 + R1 NORMAL OPERATION The input stage of this family of devices uses two differential input stages in parallel, one operates at low input voltages, and the other at high input voltages. With this topology, the input voltage is 0.3V above VDD and 0.3V below VSS. The input offset voltage is measured at both VSS - 0.3V and VDD + 0.3V to ensure proper operation. The MCP6546/6R/6U/7/8/9 family has internally-set hysteresis that is small enough to maintain input offset accuracy (<7 mV), and large enough to eliminate output chattering caused by the comparator’s own input noise voltage (200 µVP-P). Figure 4-3 illustrates this capability.

INVERTING CIRCUIT Figure 4-4 shows an inverting circuit for a single-supply application using three resistors, besides the pull-up resistor. The resulting hysteresis diagram is shown in Figure 4-5. VDD IPU VIN VOUT IOL IRF R2 RF Open-Drain Output The open-drain output is designed to make levelshifting and wired-OR logic easy to implement. The output can go as high as 10V for 9V battery-powered applications. The output stage minimizes switching current (shoot-through current from supply-to-supply) when the output changes state. See Figures 2-15, 2-18 and 2-37 through 2-41, for more information. 4.3 RPU MCP654X VDD R3 4.2 VPU MCP6548 Chip Select (CS) FIGURE 4-4: Hysteresis. Inverting Circuit with VOUT VPU VOH Low-to-High High-to-Low The MCP6548 is a single comparator with a Chip Select (CS) pin. When CS is pulled high, the total current consumption drops to 20 pA (typical). 1 pA (typical) flows through the CS pin, 1 pA (typical) flows through the output pin and 18 pA (typical) flows through the VDD pin, as shown in Figure 1-1. When this happens, the comparator output is put into a highimpedance state. By pulling CS low, the comparator is enabled. If the CS pin is left floating, the comparator will not operate properly. Figure 1-1 shows the output voltage and supply current response to a CS pulse. FIGURE 4-5: Inverting Circuit. The internal CS circuitry is designed to minimize glitches when cycling the CS pin. This helps conserve power, which is especially important in battery-powered applications. In order to determine the trip voltages (VTHL and VTLH) for the circuit shown in Figure 4-4, R2 and R3 can be simplified to the Thevenin equivalent circuit with respect to VDD, as shown in Figure 4-6. 4.4 VIN VOL VSS VSS VTLH VTHL VDD VTLH = trip voltage from low to high VTHL = trip voltage from high to low Hysteresis Diagram for the Externally Set Hysteresis VPU Greater flexibility in selecting hysteresis, or input trip points, is achieved by using external resistors. 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. Hysteresis reduces output chattering when one input is slowly moving past the other, thus reducing dynamic supply current. It also helps in systems where it is best not to cycle between states too frequently (e.g., air conditioner thermostatic control). DS21714G-page 16 RPU MCP654X + VOUT V23 R23 FIGURE 4-6: RF Thevenin Equivalent Circuit. © 2002-2012 Microchip Technology Inc. MCP6546/6R/6U/7/8/9 EQUATION 4-1: 4.6 R2R3 R 23 = ------------------R2 + R3 R3 V23 = ------------------- × VDD R2 + R3 Reasonable capacitive loads (e.g., logic gates) have little impact on propagation delay (see Figure 2-27). The supply current increases with increasing toggle frequency (Figure 2-30), especially with higher capacitive loads. 4.7 Using this simplified circuit, the trip voltage can be calculated using the following equation: EQUATION 4-2: R23 R F + R PU ⎛ ⎞ VTHL = V PU ⎜ ----------------------------------------⎟ + V23 ⎛ ---------------------------------------⎞ ⎝ ⎠ R R + R + R ⎝ 23 PU⎠ 23 + R F + R PU F RF ⎛ R23 ⎞ V TLH = VOL ⎜ -----------------------⎟ + V 23 ⎛ ----------------------⎞ ⎝ R 23 + RF⎠ ⎝ R 23 + R F⎠ VTLH = trip voltage from low to high VTHL = trip voltage from high to low Figures 2-21 and 2-24 can be used to determine typical values for VOL. This voltage is dependent on the output current IOL as shown in Figure 4-4. This current can be determined using the equation below: EQUATION 4-3: I OL = I PU + I RF V PU – VOL V 23 – V OL I OL = ⎛ --------------------------⎞ + ⎛ ------------------------⎞ ⎝ R PU ⎠ ⎝ R23 + R F ⎠ Capacitive Loads Battery Life In order to maximize battery life in portable applications, use large resistors and small capacitive loads. Avoid toggling the output more than necessary. Do not use Chip Select (CS) too frequently, in order to conserve power. Capacitive loads will draw additional power at start-up. 4.8 PCB Surface Leakage 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 1012Ω. A 5V difference would cause 5 pA of current to flow. This is greater than the MCP6546/6R/6U/7/8/9 family’s bias current at 25°C (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 4-7. VIN- VIN+ VSS VOH can be calculated using the equation below: EQUATION 4-4: R 23 + R F V OH = ( V PU – V23 ) × ⎛ ---------------------------------------⎞ ⎝ R 23 + RF + R PU⎠ As explained in Section 4.1 “Comparator Inputs”, it is important to keep the non-inverting input below VDD+0.3V when VPU > VDD. 4.5 Supply Bypass With this family of comparators, the power supply pin (VDD for single supply) should have a local bypass capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm for good edge-rate performance. © 2002-2012 Microchip Technology Inc. Guard Ring FIGURE 4-7: Example Guard Ring Layout for Inverting Circuit. 1. For the Inverting Configuration (Figures 4-4 and 4-7): 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. DS21714G-page 17 MCP6546/6R/6U/7/8/9 4.9 Unused Comparators An unused amplifier in a quad package (MCP6549) should be configured as shown in Figure 4-8. 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). 4.10 Typical Applications 4.10.1 PRECISE COMPARATOR Some applications require higher DC precision. An easy way to solve this problem is to use an amplifier (such as the MCP6041) to gain-up the input signal before it reaches the comparator.
