MN3111H
Vertical Driver LSI for Video Camera CCD Area Image Sensor
Overview
The MN3111H is a vertical driver LSI for a two-dimen-
sional interline CCD image sensor. It features a built-in
power supply circuit that, in conjunction with such
external components as four booster capacitors, six volt-
age stabilization capacitors, eight Schottky barrier diodes,
and two Zener diodes, produces stabilized +15.0V and
–10.0V power supplies from a +5.0V input and HD pulses.
Features
Single 5 volt power supply

Usage Notes
External components
1. This product requires eight Schottky barrier diodes and two Zener diodes.
We recommend the following components.
MN3111H
Schottky barrier diodes:
Zener diodes:
MA723 or equivalents
MA1150-M, MA8150-M (for positive regulated voltage) or equivalents
MA1100-M, MA8100-M (for negative regulated voltage) or equivalents

IZ=5mA, 14.6V ≤ VZ ≤ 15.35V
IZ=5mA, 9.75V ≤ VZ ≤ 10.25V
The MN3111H will not operate properly if the components do not satisfy the above specifications.
Ta=25˚C

2. Always use the specified components for peripheral circuits so as to ensure that OVEE and VL do not reverse
potentials when the power is turned off.

As the above sketch illustrates, allowing OVEE to exceed VL1 and VL2 by more than 0.7 V produces the risk
of applying a forward bias to the PN junction, turning on the parasitic transistor, and generating an
overcurrent that produces latch-up.
If this phenomenon arises, increase the size of capacitor C7 or decrease the size of capacitor C13 to increase
the OVEE time constant.
(See the sample application circuit for the locations of C7 and C13.)
