Integrated door zone systems IC with enhanced power management features


Automotive door zone IC for the front door, but with "Front drives Rear" topology for controlling most of the typical loads required by the power trunk or tailgate applications

The L99DZ200G is an automotive Door Zone device with LIN and HS-CAN communication layers for driving dual configurable H-bridges. Up to 3 DC motors and 8 external MOS transistors (4 for each of the 2 H-bridges) in H-bridge configuration can be driven. In addition, 5 high-side drivers to supply LEDs, 2 high-side drivers to supply bulbs increase the system integration level. It supports physical communication layers as well as LIN and HS CAN and integrating 2 Voltage regulators for MCU supply. Standard SPI interface allows advanced control and diagnosis of the device and enables generic software development.

Key features of L99DZ200G

  • 7 configurable high-side drivers, 4 configurable half-bridges, and 2 H-bridge gate drivers
  • One 5V voltage regulator for the MCU supply and one 5V voltage tracker for a peripheral supply
  • HS-CAN and LIN transceivers
  • Generator mode for power trunk/tailgate applications
  • Protection and supervision features (current monitor, open-load and overcurrent, thermal warning and thermal shutdown, etc.)
