Electrical tests are performed with VIN = 10V and 2k Ω pull-up resistors on all indicator outputs. All electrical specifications for the UC1544, UC2544, and UC3544 devices are tested with the inverting over-voltage input and the non-inverting under-voltage input externally connected to the 2.5V reference. TA = TJ. UC1543 UC1544 UC2543 UC2544 UC3543 UC3544 3 |
