What the BD6210HFP-TR does on the board
The BD6210HFP-TR is a fully integrated brushed DC motor driver from ROHM Semiconductor, combining control logic and a power stage in a single HRP-7 package. It drives a single brushed DC motor with a continuous output current of 500 mA, using two internal half-bridge outputs configured for forward/reverse or brake control via a simple On/Off interface. The power stage uses Power MOSFET technology, which keeps conduction losses low in a compact footprint.
The BD6210HFP-TR comes in an HRP-7 package (7 leads plus a tab), designated as supplier device package HRP7. The exposed tab provides a thermal path to the PCB copper plane — essential for dissipating heat at the 500 mA continuous output.
