The ADG5404F is an analog multiplexer composed of four single channels with fault protected inputs. The ADG5404F switches one of the four inputs to a common drain, D, as determined by the 2-bit binary address lines (A0 and A1). An enable digital input, EN, is used to disable all the switches. Each channel conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. The digital inputs are compatible with 3 V logic inputs over the full operating supply range.When no power supplies are present, the switch remains in the off condition, and the channel inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed VDD or VSS by a threshold voltage, VT, the channel turns off and that Sx pin becomes high impedance. If the channel is on, the drain pin reacts according to the drain response (DR) input pin. If the DR pin is left floating or pulled high, the drain remains high impedance and floats. If the DR pin is pulled low, the drain pulls to the exceeded rail. Input signal levels up to +55 V or ?55 V relative to ground are blocked, in both the powered and unpowered conditions.The low on resistance of the ADG5404F, combined with on-resistance flatness over a significant portion of the signal range, makes it an ideal solution for data acquisition and gain switching applications where excellent linearity and low distortion are critical.Note that, throughout this data sheet, the dual function pin names are referenced only by the relevant function where applicable.

The ADM1085-ADM1088 are Simple Sequencing? circuits which provide a time delay between the enabling of voltage regulators at power-up in multiple supply systems. When the output voltage of the first regulator reaches a preset threshold, a time delay is initiated before an enable signal allows subsequent regulators to power-up. Any number of these devices can be cascaded with regulators to allow sequencing of multiple power supplies.Threshold levels can be set with a pair of external resistors in a voltage divider configuration. By choosing appropriate resistor values, the threshold can be adjusted to monitor voltages as low as 0.6V. The ADM1086?and ADM1088 have push-pull output stages, with active-high (ENOUT) and active-low (ENOUT) logic outputs, respectively. Similarly, the ADM1085 has an active-high (ENOUT) logic output and the ADM1087 has an active-low (ENOUT) output. Both the ADM1085 and ADM1087 have open-drain output stages which can be pulled up to voltage levels as high as 22V through an external resistor.

The ADM1172 is a hot swap controller that safely enables a printed circuit board to be removed and inserted to a live backplane. This is achieved using an external N-channel power MOSFET with a current control loop that monitors the load current through a sense resistor. An internal charge pump is used to enhance the gate of the N-channel FET. When an overcurrent condition is detected, the gate voltage of the FET is reduced to limit the current flowing through the sense resistor. During an overcurrent condition, the TIMER pin capacitor determines the amount of time the FET remains at a current limiting mode of operation until it is shut down. The ON (ON-CLR) pin is the enable input for the device and can be used to monitor the input supply voltage. The ADM1172 operates with a supply voltage ranging from 2.7 V to 16.5 V.The ADM1172 also features a power-fail comparator. The voltage on the PFI pin is compared with an internal 0.6 V reference, and the output of this comparator is presented on the PFO pin. This device is available in two options: the ADM1172-1 with automatic retry for overcurrent fault and the ADM1172-2 with latch-off for an overcurrent fault. Toggling the ON (ON-CLR) pin resets a latched fault. The ADM1172 is packaged in an 8-lead TSOT.Applications Hot swap board insertion: line cards, raid systems Industrial high-side switches/circuit breakers Electronic circuit breakers

The ADM1176 is an integrated hot swap controller that offers digital current and voltage monitoring via an on-chip, 12-bit analog-to-digital converter (ADC), communicated through an I2C interface.An internal current sense amplifier senses voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.The ADM1176 limits the current through this resistor by control-ling the gate voltage of an external N-channel FET in the power path, via the GATE pin. The sense voltage (and, therefore, the inrush current) is kept below a preset maximum.The ADM1176 protects the external FET by limiting the time that it spends with maximum current running through it. This current limit period is set by the choice of capacitor attached to the TIMER pin. Additionally, the device provides protection from overcurrent events that may occur once the hot swap event is complete. In the case of a short-circuit event, the current in the sense resistor exceeds an overcurrent trip threshold, and the FET is switched off immediately by pulling down the GATE pin.A 12-bit ADC can measure the current seen in the sense resistor, as well as the supply voltage on the VCC pin. An industry-standard I2C interface allows a controller to read current and voltage data from the ADC. Measurements can be initiated by an I2C command. Alternatively, the ADC can run continuously, and the user can read the latest conversion data whenever it is required. Up to 16 unique I2C addresses can be created, depending on the way the A0 and A1 pins are connected.The ADM1176 is packaged in a 10-lead MSOP.Applications Power monitoring/power budgeting Central office equipment Telecommunication and data communication equipment PCs/servers

In the case of a short-circuit event, the current in the sense resistor exceeds an overcurrent trip threshold, and the FET is switched off immediately by pulling down the GATE pin.A soft start (SS) pin is also included. This gives the user control over the reference on the current sense amplifier. An internal current source charges a capacitor on this pin at startup, allowing the user to set the profile of the initial current ramp. A voltage can also be driven on this pin to alter the reference.A 12-bit ADC can measure the current seen in the sense resistor, as well as the supply voltage on the VCC pin.
