sensors or cameras.
Description
The L99MOD51XP is a microcontroller-driven
multifunctional actuator driver for automotive
applications. Up to two DC motors and two
grounded resistive loads can be driven with three
half bridges and two hide-side drivers.
The integrated SPI controls all operation modes
(forward, reverse, brake and high impedance).
Also, all diagnostic information is available via SPI
read.
