Product Details

Description

The L99DZ100G and L99DZ100GP are door zone systems IC providing electronic control

modules with enhanced power management power supply functionality, including various

standby modes, as well as LIN and HS CAN physical communication layers.

The two low-drop voltage regulators of the devices 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. In addition 8 high-side

drivers to supply LEDs, 2 high-side drivers to supply bulbs increase the system integration

level.

Up to 5 DC motors and 4 external MOS transistors in H-bridge configuration can be driven.

An additional gate drive can control an external MOSFET in high-side configuration to

supply a resistive load connected to GND (e.g. mirror heater). An electro-chromic mirror

glass can be controlled using the integrated SPI-driven module in conjunction with an

external MOS transistor. All 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.
