L99MOD54XP Multi-output driver for automotive applications Datasheet - production data Charge pump output for reverse polarity protection Applications L99MOD devices are recommended for those applications that need multiple motors control with additional loads in high-side configuration, such as bulbs/LEDs or requiring protected supply, like sensors or cameras. Description Features The L99MOD54XP is a microcontroller-driven multifunctional actuator driver for automotive AEC-Q100 qualified applications. Three half bridges for 0.75 A loads (R = 1600 m Up to two DC motors and three grounded DSon resistive loads can be driven with three half Two configurable high-side drivers for up to bridges and three high-side drivers. 1.5 A load (R 500= mor0.35 A load DSon (R = 1800 m) DSon The integrated SPI controls all operating modes (forward, reverse, brake and high impedance). A One high-side driver for 6load (R 100= m) DSon Also all diagnostic information is available via SPI Programmable soft start function to drive loads read. >with higher inrush currents (i.e. current 6 A, >current 1.5 A) Very low current consumption in standby mode (I < 6 A typ T 85 C) S j All outputs short circuit protected Current monitor output for high-side OUT1, OUT4, OUT5 and OUT6 All outputs over temperature protected Open-load diagnostic for all outputs Overload diagnostic for all outputs PWM control of all outputs Table 1.
