Analog Devices Inc./Maxim Integrated MAX16072RS17D2+T

Overview

MAX16072RS17D2+T from Maxim Integrated is a nanoPower microprocessor supervisory circuit with push-pull active-low reset output, 1.67V factory-trimmed threshold (±2.5% over -40°C to +85°C), 34ms reset timeout, 0.7µA supply current at 1.8V, and guaranteed reset assertion down to VCC = 1.0V - used for reliable power-on reset and brownout detection in ultra-low-power portable systems.

For engineers reviewing the MAX16072RS17D2+T datasheet, MAX16072RS17D2+T pinout, MAX16072RS17D2+T application, or MAX16072RS17D2+T equivalent, this device delivers precision voltage monitoring, manual reset capability, transient immunity, and chip-scale packaging critical for space-constrained battery-powered designs.

Technical Context

The MAX16072RS17D2+T integrates a precision band-gap reference, comparator, and internally trimmed resistors to set its 1.67V detection threshold with ±2.5% accuracy across temperature. Its push-pull active-low RESET output drives low within 20–90µs of VCC falling below VTH and remains asserted for 34ms after VCC rises above VTH + hysteresis (6.3mV).

It features a manual reset input (MR) with internal 50kΩ pullup, supports MR pulse widths as short as 0.8µs, rejects transients <100ns, and operates from 1.2V to 5.5V while consuming only 0.7µA at 1.8V - enabling direct integration into 1.8V–3.3V system rails without external components.

FAQ

What is the factory-trimmed reset threshold voltage for MAX16072RS17D2+T?

The MAX16072RS17D2+T has a factory-trimmed reset threshold of 1.67V at +25°C, with guaranteed tolerance of ±2.5% over the full operating temperature range (-40°C to +85°C). This value is confirmed in Table 1 of the official datasheet and corresponds to the "17" suffix in the part number. The MAX16072RS17D2+T uses internal trimmed resistors to achieve this accuracy without external components.

Does MAX16072RS17D2+T support manual reset functionality?

Yes, the MAX16072RS17D2+T includes an active-low manual reset input (MR) with an internal 50kΩ pullup resistor to VCC. Driving MR low asserts the active-low RESET output immediately, and reset remains active for the full 34ms timeout period after MR returns high. The MAX16072RS17D2+T tolerates MR pulses as short as 0.8µs and rejects glitches under 100ns, making it robust against switch bounce or noise.

What is the reset timeout period for MAX16072RS17D2+T?

The MAX16072RS17D2+T has a reset timeout period of 34ms (typical), with a maximum of 69ms over temperature and process variation. This value is defined by the "D2" suffix and is verified in Table 2 of the datasheet. The timeout begins after VCC rises above the threshold (1.67V) and MR is high, ensuring sufficient time for microprocessor initialization before release.

Can MAX16072RS17D2+T operate reliably at very low supply voltages?

Yes, the MAX16072RS17D2+T guarantees valid reset assertion down to VCC = 1.0V - meaning it continues to monitor and assert RESET even during severe brownout or battery depletion. Its operational voltage range starts at 1.2V (min), and its 0.7µA supply current at 1.8V enables multi-year operation on small batteries. This behavior is explicitly documented in the Electrical Characteristics table under "Guaranteed Reset Valid to VCC = 1.0V".

What package type and dimensions does MAX16072RS17D2+T use?

The MAX16072RS17D2+T uses a 1mm × 1mm, 4-bump UCSP™ (Ultra-Compact Silicon Package) with bottom-side solder bumps - identified in the datasheet as package code R41C1-1 and outline no. 21-0242. The "+" suffix denotes RoHS-compliant, lead-free construction. This chip-scale package occupies less than 10% of the area of a standard SOT-23, enabling integration into ultra-thin portable devices where PCB real estate is constrained.
