One high-side driver for 5 A load Control block with external MOS transistor for (R =100 m ) ON charging / discharging of electrochromic glass. One configurable high-side driver for up to Motor bridge driver. 1.5 A (R = 500 m ) or 0.35 A ON H-bridge control for external power transistors (R = 1600 m ) load ON One configurable high-side driver for 0.7 A Description (R =800 m ) or 0.35 A (R = 1600 m) ON ON load The L99DZ80EP is a microcontroller driven Two high-side drivers for 0.5 A load multifunctional door actuator driver for automotive (R =1600m ) applications. Up to five DC motors and five ON grounded resistive loads can be driven with six Programmable softstart function to drive loads half bridges and five high-side drivers. Four with higher inrush currents as current limitation external MOS transistors in bridge configuration value can be driven. An electrochromic mirror glass can Very low V current consumption in standby S be controlled using the integrated SPI-driven mode (I < 6 A typ T 85 C) S j module in conjunction with an external MOS Current monitor output for all high-side drivers transistor. The mirror glass can also be discharged through a negative supply. The Central two-stage charge pump integrated SPI controls all operating modes Motor bridge driver with full R down to 6 V dson (forward, reverse, brake and high impedance). All Device contains temperature warning and diagnostic information is available via SPI read. protection Table 1.
