Transient Fault Condition
When a fast rising or falling transient on NO_ exceeds
V+ or V-, the output (COM_) follows the input (NO_) to
the supply rail with only a few nanoseconds delay. This
delay is due to the switch on-resistance and circuit
capacitance to ground. When the input transient
returns to within the supply rails, however, there is a
longer output recovery time. For positive faults, the
recovery time is typically 2.5s. For negative faults, the
recovery time is typically 1.3s. These values depend
on the COM_ output resistance and capacitance. The
delays do not depend on the fault amplitude. Higher
COM_ output resistance and capacitance increase the
recovery times.
Non-Fault-Protected Pins
FETs N2 and P2 can source about ±10mA from V+ or
V- to the COM_ pin in the fault condition (Figure 1).
Ensure that if the COM_ pin is connected to a low -
impedance load, the 30mA absolute maximum current
rating is never exceeded, both in normal and fault con-
ditions.
The GND, COM_, EN, and A_ pins do not have fault
protection. Reverse ESD protection diodes are internal-
ly connected between GND, COM_, A_, EN, and both
V+ and V-. If a signal on GND, COM_, EN, or A_
exceeds V+ or V- by more than 300mV, one of these
diodes will conduct. During normal operation, these
reverse-biased ESD diodes leak a few nanoamps of
current to V+ and V-.
Fault Protection Voltage and Power-Off
The maximum fault voltage on the NO_ pins is ±40V
from ground when the power is off. With ±15V supply
voltages, the highest voltage on NO_ can be V- + 40V,
and the lowest voltage on NO_ can be V+ - 40V.
Caution: Exceeding these limits can damage the IC.
Logic-Level Thresholds
The logic-level thresholds are CMOS and TTL compati-
ble with V+ = 4.5V to 16.5V.
Applications Information
Ground
There is no connection between the analog signal
paths and GND. The analog signal paths consist of an
N-channel and a P-channel MOSFET with their sources
and drains paralleled, and their gates driven out of
phase to V+ and V- by the logic-level translators.
V+ and GND power the internal logic and logic-level
translators and set the input logic thresholds. The logic-
level translators convert the logic levels to switched V+
and V- signals to drive the gates of the channel
MOSFETs. This drive signal is the only connection
between the power supplies and the analog signals.
GND, A_, EN, and COM_ have ESD protection diodes
to V+ and V-.
Supply Current Reduction
When the logic signals are driven rail-to-rail from 0 to
+15V or -15V to +15V, the current consumption will be
reduced from 300A (typ) to 180A.
Power Supplies
The MAX4534/MAX4535 operate with bipolar supplies
between ±4.5V and ±20V. The V+ and V- supplies
need not be symmetrical, but their sum cannot exceed
the 44V absolute maximum rating.
The MAX4534/MAX4535 operate from single supplies
between +9V and +36V when V- is connected to GND.
