µPD16805 is a H-bridge driver IC from Toshiba that is used to drive camera motors. The driver has forward, reverse, and brake functions and is ideal for driving film advance or rewind motors, and auto focus or zoom motors.
The uPD16805 integrates a high‑drive H‑bridge driver circuit using low‑ON‑resistance MOSFETs. It provides forward, reverse, brake and standby functions, making it suitable for motor control in cameras, autofocus, and zoom mechanisms.
The device operates from a supply voltage of –0.5 V to +6.5 V (or +8.0 V) and can deliver a continuous DC drive current of 1 A, with a peak pulse current of 4.2 A for pulses under 200 ms. It is supplied in a 16‑pin plastic SOP (300 mil) package and includes a charge‑pump circuit for gate drive.
