Analog Devices Inc./Maxim Integrated MAX16182ANSE330K+T

Overview

MAX16182ANSE330K+T from Analog Devices is a nano-power, single-channel supervisory IC with push-pull active-low reset output, factory-set 3.30V VCC threshold (±1.0%), 240nA quiescent current, and manual reset input configurable as active-low. It monitors supply voltage in battery-powered microcontroller systems to prevent erroneous code execution during brownout or power-up.

For engineers reviewing the MAX16182ANSE330K+T datasheet, MAX16182ANSE330K+T pinout, MAX16182ANSE330K+T application, or MAX16182ANSE330K+T equivalent, key selection criteria include ultra-low ICC (240nA), WLP-4 package footprint (0.97mm × 0.97mm), factory-programmed MR debounce (20ms for level-trigger), push-pull RST drive capability (VOH = 0.8×VCC, VOL = 0.4V @ 10mA), and -40°C to +125°C operation.

Technical Context

The MAX16182ANSE330K+T implements a bandgap-based voltage comparator with 38mV hysteresis to detect VCC drops below 3.30V, asserting reset for a factory-set timeout period (here: 100ms typ, ±25% over temperature). Its internal MR trigger logic supports active-low level detection with 20ms debounce, ensuring noise immunity against mechanical switch bounce.

Unlike open-drain variants (MAX16180/MAX16181), this part uses a push-pull output stage capable of sourcing 800µA and sinking 10mA, eliminating external pull-up resistors and enabling direct interface with µP reset inputs requiring active-low assertion without external biasing.

FAQ

What is the factory-set reset threshold voltage for MAX16182ANSE330K+T?

The MAX16182ANSE330K+T has a factory-set VCC threshold of 3.30V with ±1.0% accuracy over -40°C to +125°C. This value is laser-trimmed during production and cannot be adjusted externally. The 330 suffix in the part number explicitly denotes the 3.30V option per the Selector Guide, making MAX16182ANSE330K+T suitable for systems powered by standard 3.3V rails.

Does MAX16182ANSE330K+T require an external pull-up resistor on the RST pin?

No, MAX16182ANSE330K+T does not require an external pull-up resistor on the RST pin because it features a push-pull output stage. Unlike open-drain supervisors (e.g., MAX16180), this variant actively drives both high and low states: VOH = 0.8×VCC when high, and VOL = 0.4V at 10mA sink current when low. This eliminates BOM cost and PCB area associated with external biasing components.

What is the function of the MR pin on MAX16182ANSE330K+T, and how is it configured?

The MR pin on MAX16182ANSE330K+T is a factory-programmed manual reset input configured as active-low level-trigger. When pulled low for longer than the internal 20ms debounce period, it asserts the RST output. The K suffix indicates active-low configuration, and internal 50kΩ pulldown enables direct connection to a momentary switch tied to VCC-no external resistors are needed. MR response delay is <1.1µs for edge-trigger modes, but level-trigger dominates in this variant.

What package type and dimensions does MAX16182ANSE330K+T use?

MAX16182ANSE330K+T uses a 4-bump Wafer-Level Package (WLP) with outline number 21-100638 and land pattern per Application Note 1891. Its dimensions are 0.97mm × 0.97mm × 0.5mm, with 0.35mm ball pitch. The NS suffix in the ordering code confirms the WLP package, and the +T denotes tape-and-reel packaging for automated assembly. This ultra-compact footprint is ideal for wearables and hearing aids.

What is the guaranteed operating temperature range for MAX16182ANSE330K+T?

MAX16182ANSE330K+T is fully specified and tested over -40°C to +125°C ambient temperature. This extended range is confirmed by the A suffix in the part number and applies to all electrical parameters including VTH accuracy (±1.0%), reset timeout (±25%), and supply current (240nA typ). It meets requirements for under-hood automotive modules, industrial gateways, and outdoor-deployed sensors where thermal robustness is critical.
