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 continu-
ous output current of 2A. Intended for use in demanding servo applica-
tions 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.
Auxiliary functions on this device include a dual input under-voltage com-
parator that can be programmed to respond to low voltage conditions on
two independent supplies. In response to an under-voltage condition the
power Op-Amps are inhibited and a high current, 100mA, open collector
drive output is activated. A separate Park/Inhibit command input.
The devices are operational over a 3V to 35V supply range. Internal un-
der-voltage lockout provides predictable power-up and power-down char-
acteristics.
