Analog Devices Inc./Maxim Integrated MAX16162NDK300+T

Overview

MAX16162NDK300+T from Analog Devices is a nanoPower supply supervisor IC designed for ultra-low-voltage system monitoring and glitch-free reset assertion. It monitors VIN (not VCC) with a factory-set 3.00V threshold, asserts an active-low open-drain RST output during undervoltage or power-up, and guarantees reset remains asserted until valid supply is established - even at 0V VCC. Its 825nA typical quiescent current and 0.6V–4.85V VIN range support battery-powered microcontrollers and low-voltage FPGA cores.

For engineers reviewing the MAX16162NDK300+T datasheet, MAX16162NDK300+T pinout, MAX16162NDK300+T application, or MAX16162NDK300+T equivalent, key selection criteria include its separate VIN/VCC architecture, guaranteed reset state at zero supply voltage, 3.00V threshold accuracy (±1.5%), 1.06mm × 0.73mm 4-bump WLP package, and compatibility with core voltages as low as 0.6V in portable and wearable systems.

Technical Context

The MAX16162NDK300+T implements a dedicated VIN monitoring path independent of VCC, enabling supervision of sub-1.0V processor cores while powered from a higher VCC rail. Its internal reference and hysteresis (1% VTH) ensure stable threshold detection across -40°C to +125°C.

Unlike conventional supervisors, it maintains RST in a valid logic-low state down to 0V VCC via active sink capability - eliminating undefined regions and power-up glitches. The reset timeout period is fixed at 310μs (suffix 'A'), and the RST output requires an external pullup resistor (e.g., 10kΩ) to interface with downstream logic.

FAQ

What is the exact threshold voltage of the MAX16162NDK300+T?

The MAX16162NDK300+T has a factory-trimmed VIN threshold voltage of 3.00V with ±1.5% accuracy over -40°C to +125°C. This value is fixed and non-adjustable, confirmed in Table 3 and Selector Guide of the official datasheet. The threshold applies specifically to the VIN pin, not VCC, and remains stable across full temperature and supply ranges. No external components are required to set or calibrate this threshold.

Does the MAX16162NDK300+T require a manual reset (MR) input?

No, the MAX16162NDK300+T does not include a manual reset (MR) input. It is the MAX16162 variant - distinguished from MAX16161 by omission of MR and inclusion of separate VIN/VCC pins. The device relies solely on automatic voltage monitoring for reset assertion. Any system-level manual reset must be implemented externally, as the MAX16162NDK300+T has no MR pin or internal debounce circuitry.

What package type and dimensions does the MAX16162NDK300+T use?

The MAX16162NDK300+T uses a 4-bump Wafer-Level Package (WLP) with outline number 21-100478, measuring 1.06mm × 0.73mm and 0.4mm bump pitch. This RoHS-compliant, tape-and-reel packaged device is specified in the Ordering Information table and Package Information section. It is not available in SOT-23 variants - only WLP for this specific suffix ('N').

Can the MAX16162NDK300+T monitor a 0.8V supply rail?

Yes, the MAX16162NDK300+T can monitor a 0.8V supply rail because its VIN input supports 0.6V to 4.85V - explicitly confirmed in Electrical Characteristics and General Description. However, the 3.00V threshold means it will assert reset only when VIN falls below 3.00V. To supervise a 0.8V rail, a different threshold variant (e.g., MAX16162NDK080+T) must be selected - the '300' suffix fixes the threshold at 3.00V regardless of VIN voltage level.

What is the reset timeout period for the MAX16162NDK300+T?

The MAX16162NDK300+T has a nominal reset timeout period of 310μs, corresponding to suffix 'A' per Table 1 and Selector Guide. This is the time RST remains asserted after VIN rises above the 3.00V threshold plus hysteresis (VTH + VHYS). The timeout is factory-programmed and not adjustable; measured tolerance is ±25% over temperature, yielding 233μs to 388μs in worst-case conditions.
