Output Section
It is required that the output circuit have the high sink and source abilities for MOS FET drive. It is well known that the
“totempole circuit has high sink and source ability. However, it has the demerit of high through current.
For example, the through current may reach such the high current level of 1 A, if type M51996A has the “conventional”
totempole circuit. For the high frequency application such as higher than 100 kHz, this through current is very
important factor and will cause not only the large I
This IC uses the improved totempole circuit, so without deteriorating the characteristic of operating speed, its through
current is approximately 100 mA.
