Configurable multichannel drivers for automotive systems
Key applications
QQ Engine management
QQ Junction boxes
QQ Door-module systems
QQ HVAC flap driving
QQ LED driving
High-side configured
Low-side configured
Load driving in low-side and high-side mode
In automotive applications, increasing numbers of loads
are required to be driven in high-side mode. Multichannel
switches of today are mostly either high- or low-side
configured. This requires more than one IC if mixed load
configurations need to be driven.
STMicroelectronics offers a new device family, which
provides freely configurable output drivers in either high-
or low-side mode. Flexible configurability is also the key
to many interesting applications which need a bridge
arrangement, driving DC or stepper motors.
The L9733, L9753, L9848 and L99MC6 form a family
of configurable, SPI-controlled multichannel drivers for
various loads such as incandescent lamps, LEDs, DC
motors, unipolar and bipolar stepper motors.
Because of the freely configurable power switches, the
device family offers load driving in high-side and low-side
mode.
Up to four channels can operate in PMW mode – dimming
LEDs, for example. Open-load diagnosis is provided in off
mode.
The L9753 and L99MC6 can disable the open-load
sensing current to prevent glowing LEDs.
The L99MC6 offers an adjustable slew rate for LED drive
and a cross current protection in bridge configuration.
The devices are housed in small power packages with
superior thermal performance – ideal for compact and
lightweight systems
