UCD9081RHBT Typical application Circuitry

UCD9081RHBT

The UCD9081RHBT is a variant of the UCD9081 device, a Power Supply Sequencer and Monitor integrated circuit from Texas Instruments. It's designed to manage and sequence multiple power rails in electronic systems, ensuring that each power rail is activated in the correct order and operating correctly before allowing the subsequent power rail to activate. This sequencing is crucial in complex electronic systems, like servers and telecommunications equipment, to prevent damage from incorrect power-up sequences.

1. Power Supply and Ground Connections: A reliable power source must be connected to the UCD9081RHBT. The power supply is attached to the VDD pin, and its normal voltage range is 3.0V to 3.6V. It is necessary to connect the VSS pin to the system ground. These connections ensure that the IC is powered correctly for operation.

2. Sequencing Control: The device can control up to eight power rails. Because it is programmable, the sequencing can be altered to fit the unique needs of the system being created. Each of the eight channels can be programmed to turn on or off in a particular sequence, with dependencies and timing delays.

3. Voltage Monitoring: Each of the eight channels has a corresponding voltage monitoring input. These inputs allow the UCD9081RHBT to monitor the voltage levels of each power rail it controls, ensuring that each rail is within its proper operating range before allowing the next rail in the sequence to activate.

4. Power Good Outputs: For each monitored rail, there's a corresponding "power good" output signal. This signal can be used to indicate that a specific power rail has successfully reached its operational voltage level, providing a means of intercommunication between different system components or subsystems.

5. Configuration and Interface: The device is programmable via an I2C interface, which allows for the configuration of the power-up and power-down sequences, timing parameters, and the monitoring functions. The I2C interface also enables the device to communicate status information back to a host processor, which can take actions based on the power rail statuses.

6. External Components: Depending on the application, external components like resistors and capacitors may be connected to the UCD9081RHBT for setting timing parameters, filtering, and providing stable operation.

Incorporating the UCD9081RHBT into a system design involves understanding these key aspects and ensuring that the device is correctly configured to manage the specific power sequencing requirements of the system. The use of this IC helps in improving the reliability and safety of the electronic systems by ensuring that the power rails are activated and deactivated in a controlled manner.
