STMicroelectronics L99DZ300HTR Low Side, Low Side Power Switch IC 64-Pin, LQFP-64

The STMicroelectronics Automotive Front Door Device with CAN FD and LIN 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 provides enhanced system standby functionality with programmable local and remote wake-up capability. Moreover, the 10 high-side drivers (9 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 5 DC motors and 4 external MOS transistors in H-bridge configuration can be driven in PWM mode up to 25 kHz.
