In summary, the POWR6AT6, POWR607 and POWR605 are integrated power and platform solutions that will help reduce system cost while improving reliability. Each can supervise up to six independent voltage regulators with a high degree of accuracy, the POWR607 and POWR605 are rated for 0.5% accuracy. The devices feature 10-bit ADCs and an I²C interface for the measurement of the input voltages and a 8-bit DAC for open or closed loop control of the regulator trim pin. Any of the input voltages can be compared to an internal set point register that is programmed through the JTAG interface. The available evaluation board is preprogrammed to allow evaluation of functions, such as a voltage rail varying in and out of regulation. On-board LEDs give visual verification of sequencing, power good, variable watchdog timing and reset. Two pushbuttons provide a manual reset or watch dog input. The evaluation board can be reprogrammed to test other functions via the JTAG interface or the USB port.
