3 / 32 page Preliminary Technical Data ADM1062 Rev. PrJ | Page 3 of 32 GENERAL DESCRIPTION (continued from Page 1) In addition to these functions the ADM1062 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a closed loop margining system. This enables supply adjustment by altering either the feedback node or reference of a DC/DC Converter using the DAC outputs. The supply margining can be performed, with a minimum of external components, to an accuracy of 0.5%. The margining loop can be used at In Circuit Testing of a board during production (to verify the board’s functionality at say −5% of nominal supplies), or can be used dynamically to accurately control the output voltage of a DC/DC converter. The device also provides up to ten programmable inputs for monitoring Under, Over, or out-of-window faults on up to ten supplies. In addition, ten programmable outputs are provided. These can be used as logic enables. Six of them can also provide up to a +12V output for driving the gate of an N- Channel FET which may be placed in the path of a supply. Temperature measurement is possible with the ADM1062. The device contains one internal temperature sensor and a differential input for a remote thermal diode. These are measured using the 12- bit ADC. The logical core of the device is a Sequencing Engine. This is a state machine based construction, providing up to 63 different states. This enables very flexible sequencing of the outputs, based on the condition of the inputs. The device is controlled via configuration data which can programmed into an EEPROM. All of this configuration can be programmed using an intuitive GUI based software package provided by ADI. |
