Product overview
Description
The L99MOD50XP is a microcontroller-driven multifunctional actuator driver for automotive applications.
Up to five DC motors and five grounded resistive loads can be driven with six half bridges and five high-side drivers.
The integrated SPI controls all operating modes (forward, reverse, brake and high impedance).
Also all diagnostic information is available via SPI read.
