The ADM1166 Super Sequencer? is a configurable supervisory/ sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple-supply systems. In addition to these functions, the ADM1166 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a closed-loop margining system that enables supply adjustment by altering either the feedback node or reference of a dc-to-dc converter using the DAC outputs.Supply margining can be performed with a minimum of external components. The margining loop can be used for in-circuit testing of a board during production (for example, to verify board func-tionality at ?5% of nominal supplies), or it can be used dynamically to accurately control the output voltage of a dc-to-dc converter.

The ADM1278 is a hot swap controller that allows a circuit board to be removed from or inserted into a live backplane. It also features current, voltage, power, and temperature readback via an integrated 12-bit analog-to-digital converter (ADC), accessed using a PMBus? interface. The load current is measured using an internal current sense amplifier that measures the voltage across a sense resistor in the power path via the HS+ and HS? pins. A default current limit of 20 mV is set, but this limit can be adjusted, if required.The ADM1278 limits the current through the sense resistor by controlling the gate voltage of an external N-channel FET in the power path, via the GATE pin. The sense voltage, and therefore the load current, is maintained below the preset maximum. The ADM1278 protects the external FET by limiting the time that the FET remains on while the current is at its maximum value.This current-limit time is set by the choice of capacitor connected to the TIMER pin. In addition, a constant power foldback scheme is used to control the power dissipation in the MOSFET during power-up and fault conditions. The level of this power, along with the TIMER regulation time, can be set to ensure that the MOSFET remains within safe operating area (SOA) limits.In case of a short-circuit event, a fast internal overcurrent detector responds within 320 ns and signals the gate to shut down. A 1500 mA pull-down device ensures a fast FET response.The ADM1278 features overvoltage (OV) and undervoltage (UV) protection, programmed using external resistor dividers on the UV and OV pins. A PWRGD signal can be used to detect when the output supply is valid, using the PWGIN pin to accurately monitor the output.The ADM1278 is available in a 32-lead LFCSP with a RETRY pin that can be configured for automatic retry or latch-off when an overcurrent fault occurs.Applications Servers Power monitoring and control/power budgeting Telecommunication and data communication equipment?

EVAL-ADM3055E-ARDZ is an Arduino Uno compatible Shield for an isolated controller area network with flexible data rate (CAN FD) communications port. The circuit interfaces to the local development platform via Serial Peripheral Interface (SPI) providing a simple method to add field bus communication to new and existing designs. EVAL-ADM3055E-ARDZ enables both the higher bandwidth CAN FD data rates (up to 8Mbps) demanded by modern multi-node CAN FD networks and the rugged electromagnetic compatibility (EMC) performance required by industrial environments. The circuit uses the integrated auxiliary isolated digital channel of the ADM3055E transceiver for runtime configuration of the bus termination. The switchable termination circuitry connects a 120 Ω split termination with common-mode filtering capacitor between the CAN FD bus lines. Switchable termination allows on-the-fly software configuration of termination locations when the CAN FD bus is physically altered. Using switchable termination, each node can be used at any physical location without mechanical changes to the nodes and software can track the position of terminations in the network. Additionally, the circuit can be set by the development platform to a reduced power standby state. While in the standby state, the isolated CAN FD communications port will notify the development platform of a remote wake-up request being transmitted by a remote CAN FD node to the CAN FD bus. With the ADM3055E CAN FD transceiver, the circuit provides reinforced signal and power isolation between the node and CAN FD bus. Electrical connection to the CAN FD bus may be made either by screw terminal or the CAN CiA 303-1 male 9-pin sub-D port. Because the ADM3055E transceiver has an integrated isolated dc-to-dc converter, it does not require external power to be present on the CAN FD bus. The examples focus on CAN FD networks however this circuit is backwards compatible with classical CAN networks.
