ADM1067:  Super Sequencer® with Open-Loop Margining DACs

Информация о продукте

Статус продукта:Производство

The ADM1067 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 ADM1067 integrates six 8-bit voltage output DACs. These circuits can be used to implement an open-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 capability can be used for in-circuit testing of a board during production (for example, to verify board functionality at −5% of nominal supplies), or it can be used dynamically to accurately control the output voltage of a dc-to-dc converter.

The device also provides up to 10 programmable inputs for monitoring undervoltage faults, overvoltage faults, or out-of-window faults on up to 10 supplies. In addition, 10 programmable outputs can be used as logic enables.

Six of these programmable outputs can also provide up to a 12 V output for driving the gate of an N-FET that can be placed in the path of a supply.

The logical core of the device is a sequencing engine. This state-machine-based construction provides up to 63 different states. This design enables very flexible sequencing of the outputs, based on the condition of the inputs.

The device is controlled via configuration data that can be programmed into an EEPROM. The entire configuration can be programmed using an intuitive GUI-based software package provided by Analog Devices, Inc.
