UC3178 全桥接功率放大器
UC3178 描述
The UC3178 full-bridge power amplifier, rated for continuous output current of 0.45 Amperes, is intended for use in demanding servo applications. This device includes a precision current sense amplifier that senses load current with a single resistor in series with the load. The UC3178 is optimized to consume a minimum of supply current, and is designed to operate in both 5V and 12V systems. The power output stages have a low saturation voltage and are protected with current limiting and thermal shutdown. When inhibited, the device will draw less than 1.5mA of total supply current.
Auxiliary functions on this device include a load current sensing and rectification function that can be configured with the device\x92s over-current comparator to provide tight control on the maximum commanded load current
