The ADM6326, ADM6328, ADM6346 and ADM6348 supervisory circuits feature an ultra-low 500-nA supply current.

Analog Devices (ADI) (Norwood, MA) has expanded its portfolio of supervisory ICs with new microprocessor supervisory circuits for monitoring under-voltage conditions in handheld industrial instruments, telecommunications devices, and other portable applications. The ADM6326, ADM6328, ADM6346 and ADM6348 supervisory circuits feature an ultra-low 500-nA supply current that can extend the battery life of mobile devices. Additional features include:

• A low-power option for the precision monitoring of DSP, ASIC, FPGA and other processor power supplies.
• Monitor 2.5, 3, 3.3, and 5 V voltage rails.
• A reset output during power-up, power-down and brownout conditions.
• An active low push-pull reset output (326, 346) and active open-drain output (328, 348).
• 24 reset threshold voltage options available in increments of 2.2 and 4.63V.
• A 3-lead SOT-23 package.
• A temperature range of -40° to +85°C.
