ROHM BD62321HFP Technical Note
The BD62321HFP is a full‑bridge driver for brush‑motor applications. It operates from 6 V to 32 V supply voltage and can deliver up to 3 A output current. The device uses MOSFET output stages, supports PWM control (20 kHz‑100 kHz), and includes built‑in protection circuits such as OCP, OVP, UVLO, TSD and SAP.
The note details functional descriptions, pin assignments, thermal design guidelines, and ordering information. It also explains the four basic operation modes (stand‑by, forward, reverse, brake) and the PWM control mode, together with the associated protection and safety circuits.
