FUNCTIONAL BLOCK DIAGRAM

Open-drain version (N) has only an N-channel output transistor.

[Ordering code N.]

Complementary (“CMOS”) version includes a P-channel output

transistor (dotted lines). [Ordering code C.]

GENERAL DESCRIPTION

especially for battery-powered applications because of their

extremely low 1µA operating current and small surface-

mount packaging. Each part is laser trimmed to the desired

threshold voltage which can be ordered in the range of 0.9V

to 6.0V, in 0.1V steps.

precision reference, laser-trimmed divider, hysteresis circuit

and output driver. The latter is available in either an open-

drain or complementary (“CMOS”) configuration.
