... The ADM1063 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 ADM1063 integrates a 12-bit ADC that can be used to accurately read back separate voltages. The device also provides programmable inputs for monitoring undervoltage faults, overvoltage faults, or out-of- window faults supplies ...

... Temperature measurement is possible with the ADM1063. The device contains one internal temperature sensor and two pairs of differential inputs for remote thermal diodes. These are measured by the 12-bit ADC. The logical core of the device is a sequencing engine. This state- machine-based construction provides different states. ...

... A supply comparator chooses the highest input to provide the on-chip supply. There is minimal switching loss with this architecture (~0.2 V), resulting in the ability to power the ADM1063 from a supply as low as 3.0 V. Note that the supply on the VXx pins cannot be used to power the device. An external capacitor to GND is required to decouple the on-chip supply from noise ...

... Table 6 shows the details of each input. PROGRAMMING THE SUPPLY FAULT DETECTORS The ADM1063 can have SFDs on its 10 input channels. These highly programmable reset generators enable the supervision supply voltages. The supplies can be as low as 0.573 V and as high as 14 ...
Page 15
... Thus, potentially any supply can be divided down into the input range of the VXx pin and supervised, enabling the ADM1063 to monitor other supplies, such as +24 V, +48 V, and − additional supply supervision function is available when the VXx pins are selected as digital inputs ...

... All of the internal registers in an unprogrammed ADM1063 device from the factory are set to 0. Because of this, the PDOx pins are pulled to GND by a weak (20 kΩ) on-chip pull-down resistor. As the input supply to the ADM1063 ramps up on VPx or VH, all PDOx pins behave as follows: • ...

... ADM1063 SEQUENCING ENGINE APPLICATION EXAMPLE The application in this section demonstrates the operation of the SE. Figure 25 shows how the simple building block of a single SE state can be used to build a power-up sequence for a three- supply system. Table 8 lists the PDO outputs for each state in the same SE implementation. In this system, a good 5 V supply on VP1 and the VX1 pin held low are the triggers required to start a power-up sequence ...

... Timeout delays of 100 μs to 400 ms can be programmed. FAULT AND STATUS REPORTING FAULT The ADM1063 has a fault latch for recording faults. Two registers, FSTAT1 and FSTAT2, are set aside for this purpose. A single bit is assigned to each input of the device, and a fault on that input sets the relevant bit ...

... READING or input into the SE to determine what sequencing action the ADC ADM1063 should take. Only one register is provided for each input channel. Therefore, either an undervoltage threshold or overvoltage threshold (but not both) can be set for a given channel. The round- robin circuit can be enabled via an SMBus write can be programmed to turn on in any state in the SE program ...

... DxP input NPN transistor is used, the emitter is connected to the DxN input and the base is connected to the DxP input. Figure 29 and Figure 30 show how to connect the ADM1063 to an NPN or PNP transistor for temperature measurement. To prevent ground noise from interfering with the measurement, ...

... ADM1063 To measure ΔV , the sensor is switched between operating BE currents of I and N × I. The resulting waveform is passed through a 65 kHz low-pass filter to remove noise and through a chopper- stabilized amplifier that amplifies and rectifies the waveform to produce a dc voltage proportional to ΔV measured by the ADC to produce a temperature output in 12-bit offset binary ...

Page 28
... ADM1063 The master sends a command code telling the slave device to erase the page. The ADM1063 command code for a page erasure is 0xFE (1111 1110). Note that for a page erasure to take place, the page address must be given in the previous write word transaction (see the Write Byte/Word section) ...
Page 29
... In a block read operation, the master device reads a block of data from a slave device. The start address for a block read must have been set previously. In the ADM1063, this is done by a send byte operation to set a RAM address or a write byte/word operation to set an EEPROM address. The block read operation ...
