The L99DZ81EP is a microcontroller driven multifunctional door actuator driver for automotive applications. Up to two DC motors and four high-side drivers are supported. It features current monitor output, temperature warning and protection, open-load detection, overcurrent protection, programmable PWM control, STM standard serial peripheral interface (ST-SPI 3.0), and prepared for additional fail-safe path for H-Bridge Applications.
The L99DZ81EP is a microcontroller-driven multifunctional door actuator driver designed for automotive applications. It is capable of driving up to two DC motors and four grounded resistive loads using three half bridges and four high-side drivers. The device integrates an SPI interface to control all operating modes, including forward, reverse, brake, and high impedance, while providing diagnostic information via SPI read.
