L99DZ300GTROverview
The L99DZ300GTR is a highly integrated Power Management IC (PMIC) designed for automotive door zone applications. It combines dual voltage regulators, a high-speed CAN FD transceiver, and a LIN transceiver with multiple power drivers in a single LQFP-64 package. The device features integrated half-bridge and high-side drivers for motor control and lighting, while maintaining a low standby current of 20uA for power-sensitive automotive environments.
Why Choose This Part
The L99DZ300GTR reduces PCB footprint by integrating communication physical layers and power drivers into one AEC-Q100 qualified component. It provides advanced diagnostics, including short-circuit detection on all half-bridges and programmable overcurrent recovery for handling high inrush currents. The inclusion of a 10-bit PWM timer for each high-side driver allows for precise control of dimming and motor speed without taxing the host microcontroller.
Applications
Getting Started
Start development using the EV-L99DZ200G evaluation board, which provides a reference for the L99DZ family power and communication layouts. Use an SPI-enabled microcontroller to configure the device registers and handle diagnostic interrupts. STMicroelectronics provides a dedicated Graphical User Interface (GUI) to simplify register configuration and driver testing during the prototyping phase.
