UCD90120RGCR Description

Short technical summary and product information.

The Texas Instruments UCD90120RGCR is a versatile 12-channel sequencer and system health monitor designed for robust power management applications. This device monitors and sequences up to 12 independent voltage rails, with all rails sampled every 200 µs. It integrates a 12-bit Analog-to-Digital Converter (ADC) with a 2.5V internal reference, capable of monitoring voltage, current, or temperature inputs.

 

The UCD90120RGCR offers advanced features such as six hardware comparators for rapid power supply fault response in under 80 µs, and four programmable under-voltage and over-voltage thresholds per monitor. It supports closed-loop margining for up to 10 rails and includes a watchdog timer and system reset functionality. The device is housed in a 64-VQFN (9x9 mm) package suitable for surface mounting.

 

With a wide operating supply voltage range of 3.3V to 12V and an operating temperature range of -40°C to 110°C, the UCD90120RGCR is well-suited for industrial, telecommunications, and server applications. It also features I2C/PMBus/SMBus and JTAG communication interfaces for configuration and monitoring via TI's Fusion Digital Power GUI.
