The UCD9080RHBT from Texas Instruments is an 8-channel power supply sequencer and monitor designed for applications requiring controlled power-up and power-down sequences. This IC can monitor up to eight voltage rails, sampling each rail voltage every 50 microseconds with a resolution of 3.2 millivolts.
Key features include flexible rail sequencing options, settable under- and overvoltage thresholds per rail, and configurable digital outputs for power-on reset. The device supports independent rail configuration and flexible rail shutdown, where parent rail shutdown can cascade to child rails. It communicates via an I2C interface and includes a Microsoft Windows GUI for configuration and monitoring.
Packaged in a 32-VQFN (5x5 mm) surface-mount package, the UCD9080RHBT operates within an ambient temperature range of -40°C to 85°C. Its low power consumption and robust feature set make it suitable for telecommunications, servers, networking equipment, and test equipment.
This device is ideal for any system that requires the sequencing of multiple voltage rails, ensuring proper power-up and shutdown order to protect sensitive components and ensure system stability.
