UCD9090
Features
- 1 Monitor and sequence 10 voltage rails
- All rails sampled every 400 μs
- 12-bit ADC with 2.5-V, 0.5% internal VREF
- Sequence based on time, rail and pin dependencies
- Four programmable undervoltage and overvoltage thresholds per monitor
- Nonvolatile error and peak-value logging per monitor (up to 30 fault detail entries)
- Closed-loop margining for 10 rails
- Margin output adjusts rail voltage to match user-defined margin thresholds
- Programmable watchdog timer and system reset
- Flexible digital I/O configuration
- Pin-selected rail states
- Cascading multiple devices
- Multi-phase PWM clock generator
- Clock frequencies from 15.259 k Hz to 125 MHz
- Capability to configure independent clock outputs for synchronizing switch-mode power supplies
- JTAG and I2C/SMBus/PMBus™ interfaces
2 Applications
- Industrial and ATE
- Telemunications and networking equipment
