The UCD9080 Power Supply Sequencer EVM is an evaluation module from Texas Instruments for the
UCD9080 Power Supply Sequencer and Monitor. The UCD9080 is a highly configurable, 8-channel power
supply sequencer (see SLVS692 data sheet) with four additional general-purpose digital outputs.
The hardware can be configured and monitored through a Windows™ interface running on a PC. The GUI
communicates with the hardware through the provided USB Interface Adapter, which acts as an I
2
C
master for the board.
This UCD9080EVM has this functionality:
• Sequencing for up to eight power supplies on the board using digital enable signals
• Monitoring for up to eight voltage rails on the board using analog signals
• Power supply enables can be sent off board via a header for sequencing external power supplies
(controlled using jumpers for each rail)
• External voltage rails can be connected to a header on the board for monitoring external power
supplies (controlled using jumpers for each rail)
• Sequencing for up to four digital outputs for reset circuits, etc.
• Jumpers for configuring the I
