ADM1063 POWERING THE ADM1063 The ADM1063 is powered from the highest voltage input on either the positive-only supply inputs (VPn) or the high voltage supply input (VH). This technique offers improved redundancy, because the device is not dependent on any ...
Page 13
INPUTS SUPPLY SUPERVISION The ADM1063 has 10 programmable inputs. Five of these are dedicated supply fault detectors (SFDs). These dedicated inputs are called VH and VP1 to VP4 by default. The other five inputs are labeled VX1 to VX5 and ...
Page 14
ADM1063 INPUT COMPARATOR HYSTERESIS The UV and OV comparators shown in Figure 22 are always looking at VPn. To avoid chattering (multiple transitions when the input is very close to the set threshold level), these compara- tors have digitally programmable ...

ADM1063 OUTPUTS SUPPLY SEQUENCING THROUGH CONFIGURABLE OUTPUT DRIVERS Supply sequencing is achieved with the ADM1063 using the programmable driver outputs (PDOs) on the device as control signals for supplies. The output drivers can be used as logic enables or as ...
Page 17
SEQUENCING ENGINE OVERVIEW The ADM1063 sequencing engine (SE) provides the user with powerful and flexible control of sequencing. The SE implements a state machine control of the PDO outputs, with state changes conditional on input events. SE programs can enable ...
Page 18
ADM1063 SEQUENCING ENGINE APPLICATION EXAMPLE The application in this section demonstrates the operation of the SE. Figure 27 shows how the simple building block of a single SE state can be used to build a power-up sequence for a 3-supply ...
Page 19
SEQUENCE DETECTOR The sequence detector block is used to detect when a step in a sequence has been completed. It looks for one of the inputs to the SE to change state and is most often used as the gate ...

ADM1063 VOLTAGE READBACK The ADM1063 has an on-board, 12-bit, accurate ADC for voltage readback over the SMBus. The ADC has a 12-channel analog mux on the front end. The 12 channels consist of the 10 SFD inputs (VH, VP1 to ...
Page 21
SUPPLY MARGINING OVERVIEW It is often necessary for the system designer to adjust supplies, either to optimize their level or force them away from nominal values to characterize the system performance under these conditions. This is a function typically performed ...

ADM1063 WRITING TO THE DACs Four DAC ranges are offered. They can be placed with midcode (Code 0x7F) at 0.6 V, 0.8 V, 1.0 V, and 1.25 V. These voltages are placed to correspond to the most common feedback voltages. ...
Page 23
TEMPERATURE MEASUREMENT SYSTEM The ADM1063 contains an on-chip, band gap temperature sensor, whose output is digitized by the on-chip, 12-bit ADC. Theoretically, the temperature sensor and ADC can measure temperatures from −128°C to +127°C with a resolution of 0.125°C. Because ...

ADM1063 COMMUNICATING WITH THE ADM1063 CONFIGURATION DOWNLOAD AT POWER-UP The configuration of the ADM1063 (UV/OV thresholds, glitch filter timeouts, PDO configurations, and so on) is dictated by the contents of RAM. The RAM is comprised of digital latches that are ...
