The HIP4081A is a high frequency, medium voltage full bridge N-Channel FET driver IC, which can drive every possible switch combination except those which would cause a shoot-through condition. It can switch at frequencies up to 1MHz and is well suited to driving Voice Coil Motors, high-frequency switching power amplifiers, and power supplies.
The HIP4081A is a high‑frequency, medium‑voltage full‑bridge N‑channel FET driver IC. It can drive voice‑coil motors, high‑frequency switching power amplifiers and power supplies, and is suitable for medium‑voltage brush motors and stepper motor micro‑stepping.
Key specifications include an 80 V supply rating, 2.5 A peak output current, propagation delays around 55 ns, and a maximum switching frequency of 1 MHz. The device drives a 1000 pF load at 1 MHz with typical 10 ns rise/fall times, accepts 5 V‑15 V logic inputs, and is offered in 20‑lead PDIP and SOIC plastic packages.
