A1373 and A1374
A bypass capacitor rated at 0.1
μ
F must be mounted between
the VOUT pin and the GND pin during programming. The
power supply used for programming should be capable of deliv-
ering 28 V and 300 mA.
Before beginning any Blow Fuse mode or Lock Device mode
code sequence, the device MUST be reset by cycling V
CC
power-off and power-on again. Cycling power resets the device
by setting all bitfields that have intact fuses to 0. Bitfields with
blown fuses are unaffected.
In Try Value mode, to retain register settings from previous code
sequences, do not cycle power between sequences.
When a register is selected in Register Selection mode, when
the V
PH
pulse is sent to enter the Bitfield Selection mode, the
bitfields with intact fuses in that register are reset to 0.
In Try Value mode, all bits in the register can be set in one
code sequence. For example, setting the binary value 0110 and
sending a V
PH
pulse sets code 6. However, because of the power
requirement, blowing fuses must be performed one bitfield at
a time. In order to program (blow fuses) for binary 0110, the
bitfields MUST be programmed (blown) in two different code
sequences:one setting the 0100 bit, and the other setting the 0010
bit (in either order). Power must be cycled before each of the
two sequences.
Although a bitfield cannot be reset once its fuse is blown,
additional bitfields can be blown at any time, until the device is
locked by setting the Lock bit. For example, if bit 1 (0010) has
been blown, it is possible to blow bit 0 (0001). Because bit 1 was
Programming Guidelines
already blown, the end result will be 0011 (code 3).
Before powering down the device after programming, observe
the recommended delay, to ensure that the last V
PH
pulse has
decayed before voltage drops to the V
PL
voltage. This will avoid
the generation of overlapping V
PL
and V
PH
pulses. At the end of
a Lock Device mode code sequence, the delay is not necessary.
Programming order is important in both Try Value mode and
in Blow Fuse mode. There will be a slight parametric shift in
sensitivity after programming the temperature coefficient, and a
slight quiescent voltage shift with polarity. Subsequent changes
to sensitivity can cause a shift in the quiescent output voltage.
The following order is recommended:
a.
b.
c.
d.
e.
g.
Polarity
TC Register
Sens Coarse
QVO Coarse
Sens Fine
QVO Fine
The Clamp Bit register can be programmed at any point in the
order, as no parametric shift is observed due to clamps.
The actual distribution of parametric programming ranges are
wider than the specified programming ranges, in order to take
in to account manufacturing spread. The maximum possible
attainable range can be used with the understanding that other
specified parameters might be out of datasheet specification in
the extended range. (For an example, see the chart Sensitivity
Temperature Coefficient Range, in the Typical Characteristics
section.)
