Description

The L99DZ320 is a door zone system IC providing electronic control modules with enhanced power management

power supply functionality, including various standby modes, as well as LIN and CAN FD physical communication

layers. The device has two low drop voltage regulators to supply the system microcontroller and external

peripheral loads such as sensors and provide enhanced system standby functionality with programmable local

and remote wake-up capability. Moreover, the 9 high-side drivers (8 to supply LEDs and 1 to supply bulbs)

increase the system integration level; all the high-side drivers support the constant current mode for LED module

with high input capacitance. Up to 3 DC motors and 4 external MOS transistors in H-bridge configuration can be

driven in PWM mode up to 25 kHz. All the outputs are SC protected and implement an open-load diagnosis. The

ST standard SPI interface (4.0) allows control and diagnosis of the device and enables generic software

development.
