MAX16162 nanoPower Supply Supervisor IC

Designers can now enhance system reliability in low-voltage IoT applications with the Essential Analog MAX16162 nanoPower supervisor with glitch-free power-up from Maxim Integrated Products, Inc. This supervisor IC can 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.

Key Advantages of MAX16162 Supervisor IC

  • 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 percent smaller than the closest competition

More IoT system designers are switching to microcontrollers with core voltages of 1V 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 825nA so that it provides robust protection without exacting a toll on limited power budgets. With a package size of 1.06mm by 0.73mm, this Essential Analog supervisory IC is 23 percent smaller than the closest competitive solution and helps developers save board space.

The new MAX16162 Supervisor IC is now available at Maxim Integrated’s website for $1.19 (1000-up, FOB USA) and is also available from authorized distributors.
