SPI Communication Frame Format
The table below defines the programming bits and
diagnostic bits. Fault information is sequentially clocked
out the SO pin of the NCV7703 as programming
information is clocked into the SI pin of the device. Daisy
chain communication between SPI compatible IC’s is
possible by connection of the Serial Output pin (SO) to the
input of the sequential IC (SI).

Operational Recommendations
Recommended operating voltages for this board are:
V
bat+ = 13.2 V
V
CC
= 5 V.
This board is not reverse battery protected. Damage to the
board may occur with incorrect connections. The NCV7703
device and C5 (aluminum electrolytic capacitor) are
particularly sensitive to reverse battery conditions. See the
NCV7703/D datasheet for electrical and environmental
testing limits.
