FUNCTIONAL DESCRIPTION
The L9947 is a power interface circuit designed
for a multiplex system controlled by a parallel C
bus. The bus consists of four bidirectional data
wires D0 - D3 and three control wires read/write
(R/WN), mode (MODE) and chip select (CSN).
The device needs two supply voltages. The first
voltage supplies the half bridges, high side driver
and its driving part. The second one is a 5V stabi-
lized supply. The function of the device in the typi-
cal operating modes is described in the following
tables.
