NJU7325 Single-phase DC Brushless Motor Driver IC GENERAL DESCRIPTION PACKAGE OUTLINE The NJU7325 is a dual power amplifier designed for small actuator applications. It incorporates MOS-FET transistor in NJU7325KV1 the output stage which can offer a low saturation output (DFN8-V1(ESON8-V1)) voltage in high current operation. The NJU7325 is available in small and thin surface mount packages MSOP8 (VSP8), MSOP8 (TVSP8) and ESON8-V1, which provides downsizing and thinning in motor applications.
