Pin
Signal
Name
Description
1,2
I/O1, 2
Bi-directional I/O. Can also be used as input to A/D converter. I/O can be
controlled by serial communications or by firmware as alarm inputs or level
out.
3
TSTB
Test pin for Melexis production testing.
4
FLT
Filter pin; allows for connection of a capacitor to the internal analog path.
5
OFC
Offset control output. Provides access to the internal programmed offset
control voltage for use with external circuitry.
6,7
VBN,VBP
Bridge inputs, negative and positive.
8
TMP
Temperature sensor input. An external temperature sensor can be used in
conjunction with the internal one. The external sensor can provide a
temperature reading at the location of the bridge sensor.
9
VDD
Regulated supply voltage. Used for internal analog circuitry to ensure accurate
and stable signal manipulation.
10
FET
Regulator FET gate control. For generating a stable supply for the bridge
sensor and internal analog circuitry (generates regulated voltage for VDD).
11
VDD1
Unregulated supply voltage. Used for digital circuitry and to generate FET
output.
12
VMO
Voltage mode output. Compensated sensor output voltage.
13
CMO
Current mode output. Compensated sensor output for current mode operation.
14
CMN
Current mode negative rail. Current mode return path.
15
GND
Power supply return.
16
COMS
Serial communications pin. Bi-directional serial communication signal for
reading and writing to the EEPROM.
Table 3. Pin Description
(CSGN[2:0]). The signal path can be directed
through the processor for digital processing. Two I/O
pins are available for analog inputs or digital outputs.
These pins can be used for alarms on various points
on the analog signal path and built-in or external
temperature values.
Programming and Setup
The
MLX90314
needs
to
have
the
compensation coefficients programmed for a
particular bridge sensor to create the sensor
system. Programming the EEPROM involves
some
minimal
communications
interface
circuitry, Melexis’ setup software, and a PC.
The
communications
interface
circuitry
is
available in a development board. This circuitry
communicates with the PC via a standard RS-
232 serial communications port.
