Hi. This question is possibly off topic for this AVRFreaks section.
I am getting exposure to a L9300 IC. This is from www.st.com.
A small extract from the datasheet is;
Description; The device is an integrated circuit designed for automotive environment and implemented in BCD8s_auto technology.
The device configurability involves both the supplies block and the valve drivers stage and particularly address transmission applications.
The part in the chip I am most interested in is the capacity for it to drive 6 PWMs while it is connected to either SPI or CAN. This communication provides the commands. So a request comes to the IC (via SPI or CAN) and the correct PWM current is delivered (to a valve/whatever).
The IC itself has too many pins (with all the other functions it provides). And is difficult to obtain.
I am trusting that this forum has the people who most likely can suggest an alternative.
So, firstly can any one suggest alternative units that are suitable for connection to Arduino type microcomputers ?
(Does the hobby market have any suggestions ?)
Possibly a design using an Arduino itself ?
