ADM1060ARUZ

ADM1060 is a programmable supervisory/sequencing device that offers a single chip solution for multiple power supply fault detection and sequencing in communications systems. In central offices, servers, and other infrastructure systems, a common backplane dc supply is reduced to multiple board supplies using DC to DC converters. These multiple supplies are used to power different sections of the board, such as 3.3V logic circuits, 5V logic circuits, DSP core, and DSP I/O circuits. There is usually a requirement that certain sections power up before others; for example, a DSP core may need to power up before the DSP I/O, or vice versa, to avoid damage, miscommunication, or latch-up. It facilitates this, providing supply fault detection and sequencing/combinatorial logic for upto seven independent supplies. It is widely used in application such as central office systems, servers, infrastructure network boards, high density, multivoltage system cards etc.

• Faults detected on 7 independent supplies, 4 general-purpose logic inputs
• 1 high voltage supply (2V to 14.4V), 4 positive voltage only supplies (2V to 6V)
• 2 positive/negative voltage supplies (+2V to +6V and -2V to -6V)
• Watchdog detector input timeout delay programmable from 200ms to 12.8sec
• Open collector (external resistor required), open collector with internal pull-up to VDD
• Fast internal pull-up to VDD, open collector with internal pull-up to VPn
• EEPROM 256bytes of user EEPROM, industry-standard 2-wire bus interface (SMBus)
• Guaranteed PDO low with VPn, VH = 1V
• Operating temperature is -40°C to +85°C
• Package style is 28-lead TSSOP
