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.
