Overview
The L99MC6 IC, produced by STMicroelectronics, is a highly flexible monolithic medium current output driver. It features 3 independently self-configuring high-/low-side channels (channels 1 to 3) and 3 dedicated low-side outputs (channels 4 to 6). This device is capable of controlling inductive loads, incandescent bulbs, or LEDs and can be used in various configurations, including half-bridge with crosscurrent protection.
The L99MC6 integrates a 16-bit standard serial peripheral interface (SPI) for controlling all outputs and providing diagnostic information such as normal operation, open-load in off-state, overcurrent, temperature warning, and overtemperature protection.
