FUNCTIONAL DESCRIPTION
The MCP2036 measures a sensor coil’s impedance by
exciting the coil with a pulsed DC current and
measuring the amplitude of the resulting AC voltage
waveform. The drive current is generated by the
on-chip current amplifier/driver which takes the
high-frequency triangular waveform present on the
DRVIN input, and amplifies it into the pulsed DC current
for exciting the series combination of the sensor coils.
LREF
LBTN
The AC voltages generated across the coils, are then
capacitively coupled into the LBTN and LREF inputs.
An input resistance of 2K between the inputs and the
virtual ground offsets the AC input voltages up to the
signal ground generated by the reference voltage
generator, as shown in Figure 1-1.

MCP2036 Typical Application
The coil voltages are then multiplexed into the
Synchronous Detector section by the LBTN/LREF
multiplexer. This allows the microcontroller to select
which signal is sampled by the detector. The detector
converts the coil voltages into a DC level using a
frequency mixer, amplifier, and filter.
The mixer is composed of two switches driven by the
clock present on the CLK signal input. The switches
toggle the amplifier/filter between an inverting and
non-inverting topology, at a rate equal to the clock input
frequency. This inverts and amplifies the negative side
of the signal, while amplifying the positive side. The
result is a pulsed DC signal with a peak voltage,
proportional to the amplitude of the AC coil voltage.
© 2009 Microchip Technology Inc.
The gain of the detector is set by two pairs of resistors;
one pair are the internal fixed series resistors between
the frequency mixer and the amplifier. The second
resistor pair are the two external gain set resistors
(RGAIN). The two capacitors (CFILTER) in parallel with
the external gain setting resistors form a low pass filter
which converts the pulsed DC output signal into a
smooth DC voltage which is proportional to the AC
sensor voltage input. The output of the system is
present on the VDETOUT pin, which drives the
microcontroller’s ADC input for conversion into a digital
value.
The virtual ground reference for the detector/amplifier
is generated by a second internal op amp which
produces a virtual ground equal to ½ the supply
voltage. The virtual ground is available externally at the
VREF output and used internally throughout the
detector circuit, allowing single supply operation. A
small external capacitance is required to stabilize this
output and limit noise.

1.1
Coil Driver
The coil driver produces the excitation current for the
sensor coils.
The coil driver input is derived from the digital clock
supplied to the CLK input. The digital signal is first
filtered through a low-pass filter, composed of RIN and
CIN, and passed to the DRVIN input. The driver will
create a triangular current in phase and proportional
with the input voltage. Because the digital drive into the
RIN-CIN filter has a 50% duty cycle, the voltage on the
DRVIN input will be centered at VDD/2. The relationship
between voltage, current, inductance and frequency is
shown in Equation 1-1.
EQUATION 1-1:
ΔV OUT = ( ΔI DRV • L COIL • 2 • FDRV )
1.2
The Synchronous Detector has two inputs, LREF and
LBTN, selectable by REFSEL. This routes either signal
into the frequency mixer of the detector. The frequency
mixer then converts the AC waveform into a pulsed DC
signal which is amplified and filtered.
The gain of the amplifier is user-settable, using an
external resistor, RGAIN (see Equation 1-2).
EQUATION 1-2:
Gain ∼ R GAIN ⁄ 10kOhm
An ADC plus firmware algorithm then digitizes the
detector output voltage and uses the resulting data to
detect a key press event.
Note:
VOUT = Pulsed Output Voltage
ΔI DRV = AC Drive Current Amplitude
FDRV = AC Drive Current Frequency
L COIL = Inductance of the Sensor Coil
Note:
These equations assume a 50% duty cycle.
Synchronous Detector and Output
Amplifier
1.3
The output amplifier/filter uses a
differential connection, so its output is
centered to VREF (VDD/2). The amplitude
of the detected signal should be calculated
as the difference between voltages at the
output of the detector and the reference
voltage.
Virtual Ground Voltage Reference
Circuit
To create both an inverting and non-inverting amplifier
topology, a pseudo split supply design is required. To
generate the dual supplies required, a rail splitter is
included, which generates the virtual ground by creating a voltage output at VDD/2. The output is used by the
external passive network of the Detector/Amplifier section as a reference on the non-inverting input. A bypass
capacitor of 0.1uF is required to ensure the stability of
the output. For reference accuracy, no more than 3mA
should be supplied to, or drawn from the reference
output pin.

Chip Select (CS)
The circuit is fully enabled when a logic-low is applied
to the CS input. The circuit enters in Low-Power mode
when a logic-high is applied to this input. During
Low-Power mode, the detector output voltage falls to
VREF and the supply current is reduced to 0.5 μA (typ.).
This pin has an internal pull-up resistor to ensure
proper selection of the circuit.
2.2
Voltage Reference (VREF)
VREF is a mid-scale reference output. It can source and
sink small currents and has low output impedance. A
load capacitor between 100nF and 1μF needs to be
located close to this pin.
2.3
Chip Select, Active low
Power Supply (VDD, VSS)
The VDD pin is the power supply pin for the analog and
digital circuitry within the MCP2036. This pin requires
an appropriate bypass capacitor of 100nF. The voltage
on this pin should be maintained in the 2.7V-5.5V range
for specified operation.
The VSS pin is the ground pin and the current return
path for both analog and digital circuitry of the
MCP2036. If an analog ground plane is available, it is
recommended that this device be tied to the analog
ground plane of the PCB.

The analog input to the coil driver. The triangular
waveform applied to this input should be in phase with
the clock signal for best performance.

APPLICATIONS
The MCP2036 is an Analog Front End device that uses
the electromagnetic interaction between a conductive
target and a sensing coil to detect the pressure applied
by the user on the surface of a touch panel. The device
incorporates all analog blocks for a simple inductor
impedance measurement circuit.
For an inductive touch system, two methods are used
for switching the driver and measurement circuitry
between the different sensor coils: analog multiplexers
and GPIO grounding (see Figure 3-1 and Figure 3-2).
The MCP2036 is designed to work with both

The
microcontroller is used to generate a square
wave signal and to do all the necessary operations for
proper detection of the key press event.
Then, RIN-CIN filter converts the square wave output of
the PWM into a quasi-triangular waveform.
EQUATION 3-2:
V start = VDD ⁄ 2 -ΔV
Vstop = V DD ⁄ 2 +ΔV
To calculate the amplitude of the triangular signal, the
standard charging time equation for an RC network will
be used, as shown in Equation 3-1:
EQUATION 3-1:
V ( t ) = V step • [ 1 – exp ( – t ⁄ RC ) ]
For the first half of the square wave, the capacitor CIN
is charged through RIN, for the second half, it is
discharged through RIN, and assuming that clock
signal has a 50% duty cycle factor, we can consider:
DS22186B-page 8

MCP2036
When the PWM signal switches from low-to-high or
from high-to-low, the step voltage applied to the
capacitor CIN will be:
EQUATION 3-3:
V step = ( VDD ⁄ 2 + ΔV )
Substituting in the equation for an RC network:

MCP2036
The peak-to-peak amplitude of the resulting triangular
waveform, at the coil driver input, is shown in
Equation 3-5:
EQUATION 3-5:
The total voltage across both the reference and sensor
coils would be double (two series inductors). For a
specific power supply voltage, half of this power supply,
relative to the voltage reference, is available for output
amplifier/detector. Assuming a 30% margin, the
desired gain for the detector should be about:
VPKPK = 2ΔV

1 – exp ⎛ ------------------⎞
⎝ RIN C IN⎠
VPKPK = VDD • ------------------------------------------–t
1 + exp ⎛⎝ ------------------⎞⎠
R IN C IN
Note:
VPKPK should not exceed specified value
(600mV) for best performance.
From the previous equation, the designer should
choose values for VPKPK and RIN. Using the equation
above, the value of CIN will be:
EQUATION 3-6:

⎛ V DD – V PKPK⎞

⎝ VDD + V PKPK⎠
⎝ VDD + V PKPK⎠
Note:
Assuming a power supply of 5V and
VPKPK=500mV, for RIN=3.9KΩ, CIN should
have about 320pF. A 330pF capacitor will
be used.
EQUATION 3-9:
VDD
70% • ⎛ -----------⎞
⎝ 2 ⎠
Gain = --------------------------------2 • ΔU
The gain of the amplifier is user-settable, using an
external resistor, RGAIN. The value of that resistor will
be determined using the following equation:
EQUATION 3-10:
Gain ∼ R GAIN /10kOhm
With a 10-bit ADC, using oversampling and averaging
techniques, the effective resolution is close to 11 bits.
As shown in AN1239, “Inductive Touch Sensor
Design”, the typical shift in sensor impedance is typically 3-4%, so the actual number of counts per press is
typically between 20 and 40 counts. In this way, the
microcontroller firmware could easily detect press
event.
Note:
For a power supply of 5V and ΔU = 10mV,
the resulted gain is 81. To obtain this gain,
RGAIN = 820kOhm should be used.
The amplitude of the pulsed current applied to key
inductors will be:
EQUATION 3-7:
ΔI = V PKPK • G DRV
G DRV - Gain of Coil Driver
This current produces a pulsed voltage to key inductors
ends. The amplitude of this voltage will be:
EQUATION 3-8:
ΔI
ΔU = L • ------ = L • V PKPK • G DRV • 2F

F - PWM Frequency
L - Inductance of Key Inductor
Note:
For a PWM frequency of 2 MHz and
inductor value of 2.7µH, the amplitude of
pulsed voltage will be:

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
