Ground Sense Comparators
BA2903Yxxx-C, BA2901Yxx-C
●General Description
BA2903Yxxx-C/BA2901Yxx-C, integrate two or four
independent high gain voltage comparator.
Some features are the wide operating voltage that is 2
V to 36V and low supply current. BA2903Yxxx-C,
BA2901Yxx-C are manufactured for automotive
requirements of engine control unit, electric power
steering, antilock brake system, etc.
