Offers robust protection, glitch-free supervision and eliminates power-up errors for higher system reliability

More IoT system designers are switching to microcontrollers with core voltages of 1V and below. However, traditional supervisory ICs show unreliable outputs at these lower input voltages, leaving systems vulnerable to faulty power-up. This causes the MCU to wake up in an undefined state with incorrect I/O outputs, wrong data reads or other errors.

Now, designers can enhance system reliability in low-voltage IoT applications with the Essential Analog MAX16162 nanoPower supervisor IC. It offers glitch-free power-up and resets the entire system power supply ramp, eliminating low-voltage glitches during power-up and delivering higher system reliability.

The elimination of glitches until the input voltage achieves the appropriate voltage threshold 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 825nA, providing robust protection without burdening limited power budgets. Package size of 1.06mm x 0.73mm gives this supervisory IC a 23 per cent smaller form factor than other solutions and helps developers save board space.

Essential Analog ICs deliver Maxim’s advances in low-power, high-performance, single-function products to enable next-generation innovation in multiple applications and markets.

Key Advantages

  • Glitch Free at Low Voltages: Eliminates system errors by asserting a consistent, glitch-free reset during power-up, even for inputs below 0.6V
  • nanoPower: Draws only 825nA
  • Smallest Size: 23 per cent smaller than the closest competition

“ICs operating under 1V offer tremendous advantages for power savings and IoT proliferation but come with unacceptable reliability risks when not designed properly,” said Elnaz Shayesteh, business manager for the Core Products at Maxim Integrated. “We developed the industry’s first low-voltage glitch-free supervisory IC so system developers may eliminate the errors observed during power-up. No other company offers glitch-free capability at these voltages, further solidifying Maxim Integrated’s innovation leadership in robust protection technology.” 

The MAX16162 is available on Maxim Integrated’s website and also from authorised distributors.
