L9733 Datasheet PDF - ST Microelectronics

●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
