The programmable ADM6305 and ADM6306 complete ADI’s portfolio of high accuracy supervisory ICs for monitoring low voltage supplies in single rail systems up to 12 rail systems that use complex processors such as high end microprocessors, microcontrollers, DSP Processors, FPGA, ASIC SOC, and other controller/processor ICs.

These new supervisory ICs are designed to monitor two supplies, provide a reset signal to digital processor-based systems and are ideal for dual supply processors and FPGA’s. Available in a space saving 1.7 mm x 3.0 mm SOT package, the new ADM6305 and ADM6306 expands ADI’s portfolio into the widest portfolio of high accuracy multi voltage supervisors/monitors available.

Featuring two adjustable, resistor-programmable, under-voltage reset inputs of 0.4 V and 1.23 V, the ADM6305 and ADM6306 can monitor supplies of less than 1.2 V when the threshold is set at 0.4 V. When a monitored power supply voltage falls below the minimum voltage threshold, a single, active low output triggers a system reset. Once all voltages rise above the selected threshold level, the reset signal remains low for the reset timeout period. Four reset timeout options of 1 ms (milliseconds), 20 ms, 140 ms and 1.12 seconds are also provided. The ADM6305 and ADM6306 are available in a 5-lead SOT-23 package and are specified over a temperature range of -40°C to +85°C.

“Each device’s high threshold accuracy of ±1.2 percent allows very accurate monitoring of low voltage core rails,” said Nigel Brooke, product marketing manager, Power Management Technology Group, Analog Devices. “When this is compared to the ±2.4% accuracy specified for the nearest alternative supervisors, the ADM6305 and ADM6306 are the most accurate microprocessor supervisors available.”
