L99MOD51XP Multi-output driver for automotive applications Datasheet - production data All outputs over temperature protected Open-load diagnostic for all outputs Overload diagnostic for all outputs Programmable PWM control of all outputs Charge pump output for reverse polarity protection Applications L99MOD devices are recommended for those Features applications that need multiple motors control with additional loads in high-side configuration, such AEC-Q100 qualified as bulbs/LEDs ors requiring protected supply, like One half bridge for 7.4 A load sensors or cameras. (R = 150 m) DSon Two half bridges for 5 A load (R = 200 m) DSon Description Two high-side drivers for 1.25 A load The L99MOD51XP is a microcontroller-driven (R = 800 m) DSon multifunctional actuator driver for automotive Programmable soft start function to drive loads applications. Up to two DC motors and two with higher inrush currents (i.e.current > 7.4 A, grounded resistive loads can be driven with three A, >5 A)>1.25 half bridges and two hide-side drivers. Very low current consumption in standby mode The integrated SPI controls all operation modes (I < 3 A, typ., T C) 85 S j (forward, reverse, brake and high impedance). All outputs short circuit protected Also, all diagnostic information is available via SPI Current monitor output for all high-side drivers read. Table 1.
