Analog Devices Inc./Maxim Integrated MAX16073RS17D3+T

Overview

The MAX16073RS17D3+T from Maxim Integrated is a nanoPower microprocessor supervisory circuit with push-pull, active-high reset output, 1.67V factory-trimmed threshold (±2.5% over temperature), 140ms reset timeout, and 0.7µA supply current at 1.8V. It monitors VCC in portable battery-powered systems to assert reset during power-up, brownout, or manual reset events.

For engineers reviewing the MAX16073RS17D3+T datasheet, MAX16073RS17D3+T pinout, MAX16073RS17D3+T application, or MAX16073RS17D3+T equivalent, key selection criteria include active-high push-pull drive capability, guaranteed reset validity down to VCC = 1.0V, immunity to sub-100ns VCC transients, and compatibility with 1.8V–3.6V nominal supply rails in space-constrained designs.

Technical Context

This device integrates a precision band-gap reference, comparator, and internally trimmed resistors to set a fixed 1.67V detection threshold with 40ppm/°C tempco and 6.3mV hysteresis. Its reset assertion logic responds to VCC falling below VTH or MR low, with propagation delays of 1–2µs (MR→RESET) and 20–90µs (VCC→RESET).

The MAX16073RS17D3+T operates across 1.2V–5.5V supply range, guarantees RESET high-state output voltage ≥0.8×VCC at 500µA source current, and maintains functional reset assertion down to VCC = 1.0V - enabling reliable supervision even during deep brownout conditions.

FAQ

What is the reset threshold voltage of the MAX16073RS17D3+T and how accurate is it over temperature?

The MAX16073RS17D3+T has a factory-trimmed reset threshold of 1.67V at +25°C, with guaranteed accuracy of ±2.5% across the full -40°C to +85°C operating range. This specification is achieved using internally trimmed resistors and a precision band-gap reference, eliminating the need for external calibration components in the MAX16073RS17D3+T design.

Does the MAX16073RS17D3+T support active-high reset output, and what is its drive capability?

Yes, the MAX16073RS17D3+T features a push-pull, active-high reset output. It sources up to 500µA while maintaining VOH ≥ 0.8 × VCC, enabling direct connection to microprocessor reset inputs without external pull-up resistors - a key differentiator from open-drain or active-low alternatives in the MAX16073RS17D3+T family.

What is the minimum supply voltage at which the MAX16073RS17D3+T guarantees reset assertion?

The MAX16073RS17D3+T guarantees functional reset assertion down to VCC = 1.0V, as confirmed in the Electrical Characteristics table (Note 3). This ensures deterministic behavior during deep brownout conditions where other supervisors may release reset prematurely - a critical reliability feature built into the MAX16073RS17D3+T architecture.

How does the MAX16073RS17D3+T handle fast transients on the VCC line?

The MAX16073RS17D3+T is designed to ignore fast VCC transients, with documented immunity to pulses shorter than 100ns. The Typical Operating Characteristics graph "Maximum Transient Duration vs. Reset Threshold Overdrive" quantifies this behavior, showing that a 1.67V-threshold device like the MAX16073RS17D3+T rejects transients under 100ns at typical overdrive levels - preventing false resets in noisy power environments.

What package type and dimensions does the MAX16073RS17D3+T use, and is it RoHS-compliant?

The MAX16073RS17D3+T uses a 1mm × 1mm, 4-bump UCSP™ (Ultra Compact Silicon Package) with bottom-side solder bumps (package code R41C1-1). The "+" suffix confirms RoHS compliance and lead-free finish. This chip-scale package enables ultra-dense layouts in space-constrained portable electronics where the MAX16073RS17D3+T is commonly deployed.
