When a voltage outside the supply range is applied to

most integrated circuits, there is a strong possibility they

will be damaged or “latch up” (that is, fail to operate prop-

erly even after the offending voltage is removed). If an

IC’s input or output pin is supplied with a voltage when the

IC’s power is off, and power is subsequently applied, the

device may act as an SCR and destroy itself and/or other

circuitry. Such “faults” are commonly encountered in

modular control systems where power and signals to inter-

connected modules may be interrupted and re-estab-

lished at random. They can happen during production

testing, maintenance, start-up, or a power “brownout.”

In t e rn a l Co n s t ru c t io n

Figure 1 shows the simplified internal construction of

each protector inside the MAX366/MAX367. Each circuit

consists of two N-channel FETs and one P-channel FET.

All the FETs are enhancement types; that is, the N chan-

nels must have approximately 1.3V of positive gate volt-

age in order to conduct, and the P channel must have

approximately 2V of negative gate voltage in order to

conduct.

During normal operation, V+ is connected to a positive

potential and V- is connected to a negative potential.

Since their gates are tied to V+, transistors Q1 and Q3

conduct as long as their sources are at least 1.3V below

V+ (the N-channel gate threshold.) Transistor Q2’s gate

is tied to V-, so it conducts as long as its source is 2V or

more above V- (the P-channel gate threshold.)

The MAX366/MAX367 are designed to protect delicate

input and output circuitry from overvoltage faults up to

±40V (with or without power applied), in devices such as

op amps, analog-to-digital/digital-to-analog converters,

and voltage references. These circuit protectors automati-

cally limit signal voltages and currents to safe levels with-

out degrading normal signal performance, even in very

high-impedance circuits. They are powered by the power

supply of the protected circuit and inserted into the signal

lines. There are no control lines, programming pins, or

adjustments.

V-

OUT

Unlike shunt diode networks, these devices are low-

impedance FETs that become high impedance during a

fault condition, so fault current and power dissipation are

extremely low. Equally important, leakage current during

normal and fault conditions is extremely low. In addition,

unlike most discrete networks, these parts protect circuits

both when power is off and during power transitions.
