Product details
Overview
MAX16058ATA17+T from Analog Devices is an ultra-low-power microprocessor supervisory IC with open-drain RESET output, factory-trimmed 1.665V reset threshold (±2.5% over -40°C to +125°C), 125nA typical supply current at 1.8V, capacitor-adjustable reset timeout (10.5–17.0ms with 2700pF), and integrated watchdog timer with 128× extended mode. It monitors single-supply systems in battery-powered medical and portable electronics.
For engineers reviewing the MAX16058ATA17+T datasheet, MAX16058ATA17+T pinout, MAX16058ATA17+T application, or MAX16058ATA17+T equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade (-40°C to +125°C) operation, and two rigorously cross-referenced alternative parts for low-power supervisory design.
Technical Context
The MAX16058ATA17+T implements a precision bandgap-based voltage monitor with 0.5% hysteresis and guarantees valid RESET assertion down to VCC = 1.1V. Its internal ramp-compare architecture uses SRT and SWT pins to set reset and watchdog timeouts via external capacitors, with sampling completed after RESET deassertion.
Watchdog functionality includes WDS input for 128× timeout extension, WDI falling-edge detection (150ns minimum pulse width), and automatic clearing on RESET assertion or WDS transition. The open-drain RESET output supports logic-level translation up to 5.5V and features guaranteed VOL ≤ 0.3V at 50µA sink current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.665V (typ), ±2.5% over full temperature range - ensures reliable brownout detection for 1.8V logic rails |
| Supply Current | 125nA (typ) at 1.8V/25°C - enables multi-year battery life in always-on medical sensors |
| Operating Voltage | 1.1V to 5.5V - supports direct monitoring of Li-ion, coin-cell, and 3.3V/5V system rails |
| Reset Timeout | 10.5–17.0ms (with 2700pF on SRT) - configurable to match µP power-up stabilization time |
| Watchdog Clock Period | 6.4ms (typ), ±33% over -40°C to +125°C - sets base timing resolution for firmware watchdog servicing |
| Reset Output Type | Open-drain - allows level-shifting to higher-voltage logic domains (e.g., 5V µP interface) |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
Pinout & Package
MAX16058ATA17+T is housed in a 3mm × 3mm, 8-pin TDFN-EP package with exposed pad (EP) for thermal enhancement. Pin 1 is marked by a dot; EP must be connected to GND per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RESET | Open-drain reset output | Asserts low during VCC undervoltage, MR activation, or watchdog timeout; requires external pullup |
| 2 GND | Ground reference | Primary return path for all internal circuits and external capacitor connections (SRT, SWT) |
| 3 SWT | Watchdog timeout capacitor input | Connects to GND via CSWT to set base watchdog period; grounded to disable watchdog |
| 4 MR | Manual reset input | Active-low asynchronous reset trigger; no internal pullup - must be tied to VCC if unused |
| 5 SRT | Reset timeout capacitor input | Connects to GND via CSRT to define reset assertion duration after fault clearance |
| 6 WDI | Watchdog input | Falling edge resets watchdog timer; minimum pulse width 150ns; tolerant of noisy MCU signals |
| 7 WDS | Watchdog select input | GND = normal mode (tWD); VCC = extended mode (tWD × 128); transition clears timer |
| 8 VCC | Power supply input | Monitored voltage rail; bypass with 0.1µF ceramic capacitor to GND for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 125nA typical supply current enables >10-year battery life in glucose monitors |
| Capacitor-adjustable tRP/tWD | Single external capacitor per function eliminates trimming resistors and saves PCB area |
| Watchdog capacitor open detect | SWT < 470pF forces continuous RESET assertion - detects PCB assembly defects |
| Transient immunity | Rejects 100mV VCC glitches ≤ 40µs - prevents spurious resets in noisy automotive environments |
| Valid RESET down to 1.1V | Ensures deterministic reset behavior during deep brownout conditions before µP lockup |
Applications
| Glucose Monitors | Patient Monitors |
|---|---|
Use Scenario: Continuous subcutaneous glucose sensing with Bluetooth LE transmission every 5 minutes. IC Role / Device Role / Timing Role: Supervises 1.8V coin-cell supply and triggers hardware reset if firmware hangs during BLE handshake. Use Value: 125nA ICC extends CR2032 battery life beyond 2 years; open-drain RESET interfaces directly to 3.3V BLE SoC GPIO. |
Use Scenario: Portable ECG device operating from rechargeable LiPo with sleep/wake cycles. IC Role / Device Role / Timing Role: Monitors 3.3V system rail and asserts RESET during power-up sequencing and watchdog timeout.

| Metering (Smart Meters) | HVAC Controllers |
Use Scenario: AMI smart meter with optical port and RF mesh networking. IC Role / Device Role / Timing Role: Provides brownout protection for 2.5V metrology ADC and resets communication processor on VCC sag.

Use Value: Open-drain RESET drives optocoupler input for isolated reset signaling; 125°C rating supports enclosed enclosure operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16056ATA17+T | Push-pull RESET output; identical reset threshold, watchdog, and timing specs | Requires no external pullup; unsuitable where level-shifting or wired-OR reset bus needed | Select when driving CMOS inputs directly and minimizing external components |
| TPS3808G16DBVR | Fixed 1.6V reset threshold (±0.5%), 1.6µA ICC, no watchdog, SOT-23-6 package | Lacks capacitor-adjustable timeout and watchdog; lower accuracy but tighter VTH tolerance | Select for cost-sensitive, non-watchdog applications where 1.6µA ICC is acceptable |
Compared with MAX16056ATA17+T, the push-pull variant eliminates pullup needs but forfeits level-shifting flexibility; versus TPS3808G16DBVR, MAX16058ATA17+T trades higher quiescent current for field-configurable timing and robust watchdog coverage.

FAQ
What is the factory-trimmed reset threshold voltage for MAX16058ATA17+T?
The MAX16058ATA17+T has a factory-trimmed reset threshold of 1.665V (typical), with ±1.5% tolerance at +25°C and ±2.5% over the full -40°C to +125°C operating range. This value corresponds to the "17" suffix in the part number, per Table 1 of the datasheet. The threshold is optimized for reliable supervision of 1.8V logic supplies while maintaining sufficient margin against noise-induced false resets.
Does MAX16058ATA17+T include a watchdog timer, and how is it configured?
Yes, MAX16058ATA17+T includes a fully functional watchdog timer. It is configured using three pins: SWT (capacitor input for base timeout), WDI (watchdog input for periodic clearing), and WDS (select input for 1× or 128× timeout scaling). The watchdog asserts RESET if WDI does not toggle within the programmed interval. Connecting SWT to GND disables the watchdog function entirely.
What package type and footprint does MAX16058ATA17+T use?
MAX16058ATA17+T uses an 8-pin TDFN-EP (Thin Dual Flat No-lead with Exposed Pad) package measuring 3mm × 3mm. The exposed pad (EP) must be soldered to a GND plane for thermal performance and electrical stability. Land pattern information is documented in Analog Devices' package drawing T833-2 (Outline No. 21-0137).
Can MAX16058ATA17+T operate with supply voltages below 1.8V?
Yes, MAX16058ATA17+T operates from 1.1V to 5.5V. Its 125nA typical supply current is specified down to 1.1V, and RESET output remains valid (guaranteed low) even as VCC drops to 1.1V. This enables use with single-cell alkaline, NiMH, or low-VCC energy harvesting sources where traditional supervisors fail.
How is the reset timeout period adjusted on MAX16058ATA17+T?
The reset timeout period on MAX16058ATA17+T is adjusted by connecting a capacitor (CSRT) between the SRT pin and GND. The relationship is linear: tRP = 5.15 × 10⁶ × CSRT (tRP in seconds, CSRT in farads). For example, a 2700pF capacitor yields 10.5–17.0ms timeout. Ceramic X7R capacitors are recommended for low leakage and temperature stability.
