Note 2: When using both the 1.5V and
2.0V references the current out of pin 3 should be balanced by an equivalent current into
Pin 2. The
2.0V output will change 2.3mV per A of imbalance.
Note 3: Thermal shutdown turns off the driver. If Pin 15 (O.V. Latch Output) is tied to Pin 14 (Compensation/Shutdown) the
O.V. Latch will be reset.

ELECTRICAL CHARACTERISTICS: Unless otherwise stated, these specifications apply for TA=
55°C to +125°C
for the UC1834,
40°C to +85°C for the UC2834, and 0°C to +70°C for the
UC3834. VIN+ = 15V, VIN
= 0V, TA = TJ.
