Note 2: This voltage has a positive temperature coefficient of approximately 3500ppm/°C.
Note 3: This resistance has a positive temperature coefficient of approximately 3500ppm/°C.
The total resistance from Pin 1 to Pin 8 will include an additional 60 to 100m
of package resistance.
ELECTRICAL CHARACTERISTICS: Unless otherwise stated, specifications hold for TA = 0°C to + 70°C for the
UC3835/6, –25°C to + 85°C for the UC2835/6, and –55°C to +125°C for the
UC1835/6, +VIN = 6V, Driver Source= 0V, Driver Sink = 5V, TA = TJ.
