Product details
Overview
MAX16072RS29D2+T from Maxim Integrated is a nanoPower microprocessor supervisory circuit with push-pull active-low reset output, factory-trimmed 2.93V reset threshold (±2.5% over temperature), 34ms reset timeout, and 0.7µA supply current at 1.8V. It monitors VCC in portable battery-powered systems and asserts RESET during power-up, brownout, or manual reset events.
For engineers reviewing the MAX16072RS29D2+T datasheet, MAX16072RS29D2+T pinout, MAX16072RS29D2+T application, or MAX16072RS29D2+T equivalent, this device delivers ultra-low-power voltage monitoring with guaranteed reset validity down to VCC = 1.0V, immunity to sub-100ns VCC transients, and manual reset input with internal 50kΩ pullup - critical for space-constrained, long-life embedded designs.
Technical Context
The MAX16072RS29D2+T integrates a precision band-gap reference, comparator, and internally trimmed resistors to set its 2.93V detection threshold with ±2.5% accuracy across –40°C to +85°C. Its reset assertion logic responds to VCC falling below VTH or MR low, with fixed 34ms timeout after VCC recovery or MR release.
It features push-pull active-low RESET output capable of sinking 100µA at 0.4V (VCC ≥ 1.2V) and sourcing 500µA at 0.8×VCC (VCC ≥ 1.65V), while ignoring fast VCC transients via built-in glitch rejection (100ns minimum pulse width rejection on MR, 20µs propagation delay on VCC drop).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93V ±2.5% over –40°C to +85°C - ensures reliable brownout detection for 3.0V nominal rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3123QDBVRQ1 | 3.08V threshold, 200ms timeout, 1.5µA ICC, SOT-23-5 package | Higher ICC and larger footprint; automotive AEC-Q100 qualified | Select for automotive-grade reliability where longer timeout and qualification outweigh size/power penalties |
| STM6315RWX6F | 2.93V threshold, 200ms timeout, 1.2µA ICC, SOT-23-5 package | Same threshold but 6× longer timeout; lacks MR input; higher ICC | Choose only if extended reset hold time is mandatory and manual reset is unnecessary |
Compared with TPS3123QDBVRQ1 and STM6315RWX6F, the MAX16072RS29D2+T offers the lowest ICC (0.7µA), smallest footprint (1mm²), and integrated MR - making it optimal for ultra-long-life, space-constrained consumer and industrial edge nodes where precise 2.93V detection and minimal BOM count are essential.

FAQ
What is the exact reset threshold voltage of MAX16072RS29D2+T and how accurate is it over temperature?
The MAX16072RS29D2+T has a factory-trimmed reset threshold of 2.93V at +25°C, with guaranteed accuracy of ±2.5% across the full –40°C to +85°C operating range. This is achieved using internally trimmed resistors and a precision band-gap reference, eliminating need for external calibration. The MAX16072RS29D2+T maintains this tolerance without drift compensation circuits.
Does MAX16072RS29D2+T support manual reset, and what are the electrical requirements for the MR pin?
Yes, MAX16072RS29D2+T includes an active-low manual reset (MR) input with an internal 50kΩ pullup resistor to VCC. MR asserts reset when driven below 0.3×VCC and releases reset after a 34ms timeout when pulled high. It accepts TTL/CMOS logic levels and requires no external components - a simple momentary switch to GND suffices, with optional 0.1µF capacitor for noise immunity in harsh environments.
What is the reset timeout period of MAX16072RS29D2+T, and is it adjustable?
The MAX16072RS29D2+T has a fixed 34ms reset timeout period (typical), selected by the 'D2' suffix per Table 2 in the datasheet. This timeout is internally generated and non-adjustable - it ensures sufficient hold time for microprocessor initialization without external RC networks. The MAX16072RS29D2+T guarantees 34ms ±15ms over temperature and supply voltage variations.
Can MAX16072RS29D2+T operate reliably at very low supply voltages, and what is its minimum functional VCC?
Yes, MAX16072RS29D2+T guarantees valid reset assertion down to VCC = 1.0V, supporting deep brownout detection in aging battery applications. Its operating voltage range is specified from 1.2V to 5.5V, with supply current remaining stable at 0.7µA (typical) even at 1.2V. The MAX16072RS29D2+T continues to monitor and assert RESET correctly until VCC drops below 1.0V.
What package type and footprint does MAX16072RS29D2+T use, and are soldering guidelines available?
MAX16072RS29D2+T uses a 1mm × 1mm, 4-bump UCSP™ (Ultra Compact Silicon Package) with R41C1-1 outline and bottom-side solder bumps. It is RoHS-compliant (indicated by '+' suffix) and rated for reflow up to +260°C. Land patterns and soldering recommendations are published by Maxim Integrated under package code R41C1-1 at maximintegrated.com/packages - no thermal pad or special stencil required.
