PIN DESCRIPTION
Descriptions of the pins are listed in Table 2-1.
TABLE 2-1:
PIN FUNCTION TABLE
2.1
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
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.
2.4
Inductor Inputs (LREF, LBTN)
These pins are inputs for the external coils (reference
and sensor). The inputs should be AC coupled to the
coils by a 10nF ceramic capacitor.
2.5
Input Selection (REFSEL)
Digital input that is used to select between coil inputs
(reference and sensor).
2.6
Clock (CLK)
The external clock input is used for synchronous
detection of the AC waveforms on the coils. The clock
signal is also used to generate a triangular waveform
applied to coil driver input.
2.7
Inductor Driver Input (DRVIN)
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.
2.8
Inductor Driver Output (DRVOUT)
Driver output used to excite the sensor coils. It is a
current-mode output designed to drive small inductive
loads.
