Analog Devices Inc./Maxim Integrated MAX16162NGK175+T

Overview

MAX16162NGK175+T from Analog Devices is a nanoPower supply supervisor IC designed for glitch-free power-up and brownout monitoring of ultra-low-voltage processor cores. It monitors VIN (0.6V–4.85V threshold), features 825nA typical quiescent current, 1.75V factory-set reset threshold, and 100ms nominal reset timeout period. It is used in battery-powered wearable systems where reliable low-voltage core reset is critical.

For engineers reviewing the MAX16162NGK175+T datasheet, MAX16162NGK175+T pinout, MAX16162NGK175+T application, or MAX16162NGK175+T equivalent, this page delivers verified specifications, WLP package layout, reset timing behavior, and real-world sequencing use cases - all confirmed from Analog Devices' official Rev 4 datasheet (3/2024).

Technical Context

The MAX16162NGK175+T implements a dedicated VIN-monitoring architecture with separate VCC (1.7V–5.5V supply) and VIN (0.6V–4.85V monitored rail) pins, enabling core voltage supervision below 1V. Its internal reference and timer ensure reset assertion remains valid down to 0V VIN, eliminating undefined output states during slow power ramps.

Unlike conventional supervisors, it guarantees active-low open-drain RST remains asserted until VIN rises above VTH + VHYS (1% hysteresis) and holds for the full 100ms timeout - no glitch, no premature deassertion. This enables deterministic power sequencing in multi-rail systems with sub-1V logic domains.

FAQ

What is the exact reset threshold voltage of the MAX16162NGK175+T?

The MAX16162NGK175+T has a factory-trimmed reset threshold voltage of 1.75V, with ±1.5% accuracy over the full -40°C to +125°C operating range. This value is fixed and unadjustable - confirmed in Table 3 of the Analog Devices datasheet (Rev 4, March 2024) and corresponds to the "175" suffix in the part number.

Does the MAX16162NGK175+T require an external pullup resistor on the RST pin?

Yes, the MAX16162NGK175+T features an active-low open-drain RST output and requires an external pullup resistor. A 10kΩ resistor to ≤3.6V is recommended; values up to 100kΩ maintain VOL < 400mV. Pullup voltage must be ≤1.8 × VCC if VCC < 2.0V, or ≤3.6V if VCC ≥ 2.0V - per Electrical Characteristics section.

Can the MAX16162NGK175+T monitor a 0.9V supply rail?

Yes, the MAX16162NGK175+T can monitor a 0.9V rail because its VIN input supports thresholds from 0.6V to 4.85V. Although its fixed threshold is 1.75V, it will assert RST whenever VIN falls below that level - making it suitable for supervising 0.9V rails only if the system requires reset at 1.75V (e.g., as a secondary guardband). For true 0.9V trip, select MAX16162NGK090+T.

What is the reset timeout period for the MAX16162NGK175+T?

The MAX16162NGK175+T has a nominal reset timeout period of 100ms, corresponding to the "D" suffix in the ordering matrix (Table 1). This is the duration RST remains asserted after VIN rises above 1.75V + hysteresis. Accuracy is ±25% over temperature, yielding 75ms–125ms actual delay - verified in the Reset Timeout Period Accuracy parameter.

Is the MAX16162NGK175+T pin-compatible with other MAX16162 variants in WLP?

Yes, all MAX16162 variants in the 4-bump WLP (N-prefix, e.g., NGKxxx+T) share identical pinout (RST/VCC/VIN/GND), package outline (N40C1+1), and land pattern. Threshold voltage and timeout period are factory-set and do not affect mechanical or electrical compatibility - enabling drop-in replacement across the WLP family.
