Designers can enhance system reliability in low-voltage IoT applications with the Essential Analog MAX16162 nanoPower supervisor with glitch-free power-up from Maxim Integrated Products. This supervisor IC is said to be the industry’s first to fully assert a system reset through the entire system power supply ramp, thereby eliminating low-voltage glitches during power-up and delivering higher system reliability.
More IoT system designers are switching to microcontrollers (MCU) with core voltages of 1 V and below and traditional supervisory ICs show unreliable outputs at these lower input voltages. This leaves systems vulnerable to faulty power-up, causing the MCU to wake up in an undefined state with incorrect I/O outputs, wrong data reads or other errors. The MAX16162, part of Maxim’s Essential Analog family of robust protection ICs, eliminates glitches until the input voltage achieves the appropriate voltage threshold. Eliminating glitches improves reliability not only for IoT systems, but also portable medical monitoring devices, wearables, base stations, programmable logic controllers and automation controls.
The MAX16162 draws only 825 nA, so that it provides robust protection without exacting a toll on limited power budgets. With a package size of 1,06 mm by 0,73 mm, this IC is 23% smaller than competitive solutions and helps developers save board space.
