Description
●The L9733 IC is a highly flexible monolithic, medium current, output driver that incorporates 8
●outputs that can be used as either internal low or high side drives in any combination.
●Outputs 1-8 are self-configuring as high or low side drives. Self-configuration allows a user to
●connect a high or low side load to any of these outputs and the L9733 will drive them correctly as
●well as provide proper fault mode operation with no other needed inputs. In additon, Outputs 6, 7 and 8 can be PWM controlled via a external pins (IN6-8).
●Features
●■ Eight independently self configuring low/high drivers
●■ Supply voltage from 4.5V to 5.5V
●■ RON(max)=0.7Ω@ Tj = 25°C,
● RON(max)=1.2Ω@Tj= 125°C
●■ Minimum current limit of each output 1A
●■ Output voltage clamping min. 40V in low side configuration
●■ Output voltage clamping max. -14V in high side configuration
●■ SPI interface for outputs control and for diagnosis data communication
●■ Additional PWM inputs for 3 outputs
●■ Independent thermal shutdown for all outputs Open load, Short to GND, short to Vb,
●Overcurrent diagnostics in latched or unlatched mode for each channel
●■ Internal charge pump without need of external capacitor
●■ Controlled SR for reduced EMC
