APPLICATION INFORMATION
1
By forcing the PROG input pin high, the chip enters programming mode: the multifunction pins PW_OK and
PS_ON are then disconnected from their normal functions (output pins) and are connected to internal logic as
DATA and CLOCK inputs respectively, allowing chip programming even when the device is assembled on the
application board. Onboard chip programming allows:
– selecting some working options;
– reference voltage setpoints adjusting.
It is also possible to verify the expected results before programming the chip definitively, in first instance, data
can be loaded into a re-writeble volatile memory (a flip-flop array) where they are kept as long as the chip is
supplied and can be changed as many times as one desires. A further operation is necessary to confirm the
loaded data and permanently store them into a PROM (a poly-fuse array) inside the IC.
Several steps compose the trimming/programming process:
1. PROG pin is forced high;
2. a clock signal is sent to the PS-ON/clock pin;
3. a byte with the following structure:
MSB
D3
D2
D1
D0
Data
ONBOARD DIGITAL TRIMMING AND MODE SELECTION
is serially sent to the PW-OK/DATA pin and loaded into the IC's volatile memory bit by bit on the falling edges
of the clock signal (see Fig. 16); "Address" is the identification code of the parameter that has to be trimmed
and "Data" contains the tuning bits;
4. PROG pin is forced low (warning: Vdd must never fall below V
ddUVL0
during this process otherwise the con-
tents of the volatile memory will be lost) and the result of the previous step is checked;
5. after any iterations of the steps 1-4 that might be necessary to achieve the desired value, force PROG pin
high and send the following burn code
MSB
0
0
0
0
to permanently store the data in the PROM memory.
Table 1 shows the list of the 6 programmable classes of functions, each one identified by a different code
A0..A3, and the corresponding trimmable parameter(s); in table 2 it is possible to find the trim coding for the E/
A reference setpoints and in table 3 all the selections mode option coding are showed. The timing diagram of
fig. 16 shows the details of data acquisition.
