DESCRIPTION
The L9942 is a Super Smart Power device using
BCD60III mixed technology combining an 8bit
ST6 microcontroller and its periphery with a high
current motor bridge, a voltage regulator, a 2.0A
CAN bus (protocol handler and bus interface).
This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
