L99DZ80EP：Door actuator driver
The L99DZ80EP is a microcontroller driven multifunctional door 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. Four external MOS transistors in bridge configuration can be driven. An electrochromic mirror glass can be controlled 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 controls all operating modes (forward, reverse, brake and high impedance). All diagnostic information is available via SPI read.
