Description

The L9733 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 addition, outputs 6, 7 and

8 can be PWM controlled via a external pins (IN6-8).

This device is capable of switching variable load

currents over the ambient range of -40 °C to

+125 °C. The outputs are MOSFET drivers to

minimize Vdd current requirements. For low-side

configured outputs an internal zener clamp from

the drain to gate with a breakdown of 50 V

minimum will provide fast turn off of inductive

loads. When a high-side configured output is

commanded Off after having been commanded

On, the source voltage will go to (VGND - 15 V).

An 16 bit SPI input is used to command the 8

output drivers either "On" or "Off", reducing the

I/O port requirement of the microcontroller.

Multiple L9733 can be daisy-chained. In addition

the SPI output indicates latched fault conditions

that may have occurred.
