[Outline]
This IC is a features a built-in latch-up release function (patent pending) with (1) Latch-up detection ⇒ (2) Power source shut-off ⇒ (3) Latch-up release ⇒ (4) Automatic recovery sequence, which helps to prevent damage to micro-computers caused by latch-up. The use of bi-polar processing and a noise suppression element result in a design that makes it diffi cult for the IC itself to cause damage due to latch-up or static electricity. Results of static electricity noise/electric fi eld noise/magnetic fi eld noise tests that comply with IEC61000-4-2 (Electrostatic Discharge Immunity Tests) have show a much better ability to withstand noise than Mitsumi's previous products.


[Features]
1.Latch-up Release Function(current detection threshold, detection delay time and recovery delay time
     can be set)
2.Resilient against noise(IEC61000-4-2 Contact Discharge Test immunity 25kV)
3.Wide operating voltage range(maximum operating voltage 14V)
