- I2C interface programs 1.025V< VREF1<1.612V, the VDD output voltage reference
- I2C also programs the VTT tracking ratio ?25 %, and provides digital ON/OFF control
- Four different I2C addresses are selectible using 2 ADDR pins
- Four different VREF1 voltages are selectible using 2 VID pins if I2C communication is not available
- VTT tracking defaults to ?the VDD Remote Sense Amp output voltage
- Power Good output driven by an external bias input
- VDD to VTT overvoltage protection
- Soft-Stop turn-off to ensure VDDR and Vtt tracking
- Fault activated Crowbar pin to drive external NMOS devices for external output voltage protection
- Pin programmable slew rate of I2C programmed VREF1 voltage transitions
- 0.5% overall VDD system set point accuracy
- Remote sense amplifiers provide differential sensing and requires less than 50uA bias current
- Pin programmable per phase switching frequency of 250kHz to 1.5MHz
- Complete protection including over-current, over-voltage, open remote sense, and open control
