The L99H92 is designed to drive 4 external N-channel MOSFET transistors in single H-bridge or dual independent half bridge configuration for DC-motor control in automotive applications. Two free configurable current sense amplifiers are integrated. The device has a low power mode (standby mode) where the current consumption is less than 5 µA. Programmable gate driving current allows minimizing EMI. Each gate driver monitors independently its external MOSFET drain-source voltage for fault conditions. Programmable cross current protection time avoids concurrency of high side and low side activation for each half bridge. Two off-state diagnostic comparators detect potential short to ground, short to battery or open load conditions. The integrated standard serial peripheral interface (SPI) controls the device and provides diagnostic information. An additional DIAGN output pin alerts the microcontrollers of a fault occurred into the device faster than the SPI communication. The L99H92 device implements diagnostic and protection features such as supply voltage monitoring, charge pump voltage monitoring, overcurrent protection, temperature warning and overtemperature shutdown. The devices are hosted in a TQFP32 and a QFN32 package both with exposed pad. QFN32 has wettable flanks for easy visual inspection of the solder joint.

The L99LD21-ADIS discovery board enables you to drive four independent high brightness LED strings for automotive front lighting applications by connecting it to the SPC560B-DIS discovery board, application firmware examples and GUI are available.

The L99LDLH32 is a monolithic 32-channel linear current regulator specifically designed for automotive exterior O/LED rear lighting applications. Thanks to the high side configuration of the output channels, the L99LDLH32 is suitable to drive OLED panel with common cathode. It guarantees up to 35 V output driving capability - to cover the OLED forward voltage wide spread - and features 32 regulated current sources able to provide from 1 mA up to 15 mA individually programmable current to drive each pixel of the OLED panel independently. As the other device in the family (L99LDLL16), the L99LDLH32 integrates a robust purely automotive CAN FD Light compatible communication interface which allows a high rate data transmission (up to 1 Mbit/s) and uses CAN FD structure for long frames. Besides the CAN FD Light compatible physical layer, the device also integrates the protocol handler, so no additional external devices are needed to facilitate communication with Commander ECU. The L99LDLH32 can operate in bus mode using CAN FD Light compatible interface or in stand-alone/fail-safe mode using internal Few Time Programmable (FTP) memory registers.

The L99MC6 IC is a highly flexible monolithic medium current output driver that incorporates 3 dedicated low-side outputs (channels 4 to 6) and 3 independently self configuring outputs (channels 1 to 3) that can be used as either low-side or high-side drivers in any combination. The L99MC6 can control inductive loads, incandescent bulbs or LEDs. The L99MC6 can be used in a half bridge configuration with crosscurrent protection. The channel 2 can be controlled directly via the IN/PWM pin for PWM applications. The IN/PWM signal can be applied to any other output. The integrated 16-bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in off-state, overcurrent, temperature warning, overtemperature.

The L99MC6GJ IC is a highly flexible monolithic medium current output driver that incorporates 3 dedicated low-side outputs (channels 4 to 6) and 3 independently self configuring outputs (channels 1 to 3) that can be used as either low-side or high-side drivers in any combination. The L99MC6GJ can control inductive loads, incandescent bulbs or LEDs. The L99MC6GJ can be used in a half bridge configuration with crosscurrent protection. The channel 2 can be controlled directly via the IN/PWM pin for PWM applications. The IN/PWM signal can be applied to any other output. The integrated 16-bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in off-state, overcurrent, temperature warning, overtemperature.

The L99MD02 IC is a 6 x half bridge driver for automotive applications. The device is intended to drive DC-motors. It is possible to drive 3 DC-motors simultaneously or up to 5 DC-motors sequentially. The integrated 24 bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in on-state, overcurrent, temperature warning and overtemperature.
