FEATURES
● Three half bridges for 1.5A load (Ron=800mΩ)● One highside driver for 6A load (Ron=100mΩ)
● Two highside drivers for 1.5A load (Ron=800mΩ)
● Programmable softstart function to drive loads with higher inrush currents (i.e. current >6A, >1.5A)
● Very low current consumption in standby mode (IS < 6µA typ; Tj ≤ 85 °C)
● All outputs short circuit protected
● Current monitor output for highside 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
● Charge pump output for reverse polarity protection PowerSO-36 PowerSSO-36
APPLICATIONS
● Door actuator driver with bridges for mirror axis control and highside driver for mirror defroster and two 10W-light bulbs.DESCRIPTION
Up to two DC motors and three grounded resistive loads can be driven with three half bridges and three highside drivers. All diagnostic information is available via the SPI. Table 1. Device summar...
