The ADM1490E / ADM1491E are RS-485/RS-422 transceivers with ±8 kV ESD protection and are suitable for high speed, full-duplex communication on multipoint transmission lines. In particular, the ADM1490E/ADM1491E are designed for use in motor control applications requiring communications at data rates up to 16 Mbps.The ADM1490E / ADM1491E are designed for balanced transmission lines and comply with TIA/EIA-485-A-98. The devices each have a 12 kΩ receiver input impedance for unit load RS-485 operation, allowing up to 32 nodes on the bus.The differential transmitter outputs and receiver inputs feature electrostatic discharge circuitry that provides protection to ±8 kV using the human body model (HBM).The ADM1490E / ADM1491E operate from a single 5 V power supply. Excessive power dissipation caused by bus contention or output shorting is prevented by short-circuit protection and thermal circuitry. Short-circuit protection circuits limit the maximum output current to ±250 mA during fault conditions. A thermal shutdown circuit senses if the die temperature rises above 150°C and forces the driver outputs into a high impedance state under this condition.The receiver of the ADM1490E / ADM1491E contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).The ADM1490E / ADM1491E feature extremely fast and closely matched switching times. Minimal driver propagation delays permit transmission at data rates up to 16 Mbps, and low skew minimizes EMI interference.The ADM1490E/ADM1491E are fully specified over the commercial and industrial temperature ranges. The ADM1490E is available in two packages: a narrow body, 8-lead SOIC and an 8-lead MSOP.

The ADM2914 is a quad voltage supervisory IC ideally suitedfor monitoring multiple rails in a wide range of applications.Each monitored rail has two dedicated input pins, VHx and VLx, which allow each rail to be monitored for both overvoltage (OV) and undervoltage (UV) conditions. A common active lowundervoltage (UV) and overvoltage (OV) pin is shared by each of the monitored voltage rails.The ADM2914 includes a 1 V buffered reference output, REF,that acts as an offset when monitoring a negative voltage. Thethree-state SEL pin determines the polarity of the third andfourth inputs, that is, it configures the device to monitorpositive or negative supplies.The device incorporates an internal shunt regulator that enablesthe device to be used in higher voltage systems. This featurerequires a resistor to be placed between the main supply rail andthe VCC pin to limit the current flow into the VCC pin to no greater than 10 mA. The ADM2914 uses the internal shuntregulator to regulate VCC if the supply line exceeds the absolute maximum ratings.The ADM2914 is available in two models. The ADM2914-1offers a latching overvoltage output that can be cleared by toggling the LATCH input pin. The ADM2914-2 has a disablepin that can override and disable both the OV and UVoutputsignals.The ADM2914 is available in a 16-lead QSOP package. Thedevice operates over the extended temperature range of −40°Cto +125°C.Applications Server supply monitoring FPGA/DSP core and I/O voltage monitoring Telecommunications equipment Medical equipment

The ADM6305 / ADM6306 are dual voltage supervisors designed to monitor two supplies and provide a reset signal to DSP- and microprocessor-based systems. Low supply current and a small form factor make these devices suitable for portable and battery-operated applications.If a monitored power supply voltage falls below the minimum voltage threshold, a single active low output asserts triggering a system reset. Once all voltages rise above the selected threshold level, the reset signal remains low for the reset timeout period. Four reset timeout options are available.The ADM6305 monitors two supplies via two adjustable resistor-programmable undervoltage reset inputs. Both RST IN1 and RST IN2 have a reset threshold of either 0.4 V or 1.23 V depending on the particular model; that is, the RST IN1 and RST IN2 threshold of the ADM6305DxARJZ model is 1.23 V, while in the case of ADM6305DxARJZ1 model, it is 0.4 V. The VCC input of the ADM6305 is not a monitored input.The ADM6306 has one adjustable undervoltage reset input, RST IN, which features a choice of reset threshold, 0.4 V or 1.23 V (see the Ordering Guide for more information). The ADM6306 incorporates a variety of internally pretrimmed VCC undervoltage threshold options for monitoring supply voltages in increments between 2.5 V and 5 V. The ADM6306 also includes a manual reset input.The ADM6305 / ADM6306 RESET output remains valid as long as VCC exceeds 0.9 V.The ADM6305 / ADM6306 are available in a 5-lead SOT-23 package. These devices are specified over the temperature range of −40°C to +125°C.APPLICATIONS Portable/battery-operated equipment Microprocessor systems Multivoltage applications
