UC3176 UC3177 Full Bridge Power Amplifier FEATURES • Dual Power Operational Amplifiers • ±2A Output Current Guaranteed • Precision Current Sense Amplifier • Two Supply Monitoring Inputs • Parking Function and Under-Voltage Lockout • Safe Operating Area Protection • 3V to 35V Operation DESCRIPTION The UC3176/7 family of full bridge power amplifiers is rated for a continuous output current of 2A. Intended for use in demanding servo applications such as disk head positioning, the onboard current sense amplifier can be used to obtain precision control of load current, or where voltage mode drive is required, a standard voltage feedback scheme can be used. Output stage protection includes foldback current limiting and thermal shutdown, resulting in a very rugged device.
