Data sheet:
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.
