Current ranges in excess of 1.2 A or at high power supply consisting of programmable force voltages and current and high voltage combinations can be achieved by measure ranges. This part includes the required DAC levels to paralleling or ganging multiple DPS devices. Open-drain alarm outputs are provided in the event of overcurrent, set the programmable inputs for the drive amplifier, as well as clamping and comparator circuitry. Offset and gain correction overtemperature, or Kelvin alarm on either the SENSE or is included on-chip for DAC functions. A number of program- DUTGND line. mable measure current ranges are available: five internal fixed The DPS functions are controlled via a simple 3-wire serial ranges and two external customer-selectable ranges (EXTFORCE1 interface compatible with SPI, QSPI, MICROWIRE, and DSP and EXTFORCE2) that can supply currents up to 1.2 A and interface standards running at clock speeds of up to 50 MHz. 500 mA, respectively. The voltage range possible at this high current level is limited by headroom and the maximum power Rev.
