STMicroelectronics L99DZ80 Door Actuator Drivers

COMING SOON! STMicroelectronics' L99DZ80 Door Actuator Drivers are a microcontroller driven multifunctional door actuator driver for automotive applications. Up to five DC motors and five grounded resistive loads the L99DZ80 Door Actuator Drivers can be driven with six half bridges and five high-side drivers. Four external MOS transistors in bridge configuration can be driven as well. An electrochromic mirror glass can be controlled with STMicroelectronics L99DZ80 Door Actuator Drivers using the integrated SPI-driven module in conjunction with an external MOS transistor. The mirror glass can also be discharged through a negative supply. The integrated SPI of the L99DZ80 Door Actuator Drivers controls all operating modes (forward, reverse, brake and high impedance).
