1 / 9 page UC1834 UC2834 UC3834 High Efficiency Linear Regulator FEATURES • Minimum VIN - VOUT Less Than 0.5V At 5A Load With External Pass Device • Equally Usable For Either Positive or Negative Regulator Design • Adjustable Low Threshold Current Sense Amplifier • Under And Over-Voltage Fault Alert With Programmable Delay • Over-Voltage Fault Latch With 100mA Crowbar Drive Output DESCRIPTION The UC1834 family of integrated circuits is optimized for the design of low input-output differential linear regulators. A high gain amplifier and 200mA sink or source drive outputs facilitate high output current designs which use an external pass device. With both positive and negative precision refer- ences, either polarity of regulator can be implemented. A current sense am- plifier with a low, adjustable, threshold can be used to sense and limit currents in either the positive or negative supply lines. In addition, this series of parts has a fault monitoring circuit which senses both under and over-voltage fault conditions. After a user defined delay for transient rejection, this circuitry provides a fault alert output for either fault condition. In the over-voltage case, a 100mA crowbar output is activated. An over-voltage latch will maintain the crowbar output and can be used to shutdown the driver outputs. System control to the device can be accom- modated at a single input which will act as both a supply reset and remote shutdown terminal. These die are protected against excessive power dissi- pation by an internal thermal shutdown function. BLOCK DIAGRAM 6/94 |
