The UCD9090RGZT from Texas Instruments is an active 10-channel power supply sequencer and system health monitor. This device is designed to monitor and sequence up to 10 voltage rails, with all rails sampled every 400 microseconds. It features a 12-bit Analog-to-Digital Converter (ADC) with a 2.5-V internal voltage reference that has 0.5% accuracy.
Sequencing can be based on time, rail, or pin dependencies. The UCD9090RGZT includes four programmable undervoltage and overvoltage thresholds per monitor, along with nonvolatile error and peak-value logging capabilities for up to 30 fault detail entries. It also supports closed-loop margining for 10 rails, allowing margin outputs to adjust rail voltage to user-defined thresholds.
Additional features include a programmable watchdog timer and system reset, flexible digital I/O configuration, and pin-selected rail states. The device supports cascading multiple units and includes a multi-phase PWM clock generator with frequencies ranging from 15.259 kHz to 125 MHz. Communication interfaces include JTAG, I2C, SMBus, and PMBus.
The UCD9090RGZT is supplied in a 48-VQFN (7x7 mm) package and is designed for surface mount applications. It operates within a temperature range of -40°C to 125°C.
