Product details
Overview
The MAX16059ATT30+ from Analog Devices is a 6-pin TDFN ultra-low-power microprocessor supervisory circuit with factory-trimmed 3.000V reset threshold, 125nA typical supply current, and capacitor-adjustable reset timeout (10.5–17.0ms). It monitors single VCC supply (1.1–5.5V), asserts active-low RESET on brownout or manual reset, and guarantees valid RESET down to VCC = 1.1V - used in glucose monitors and portable medical devices for reliable power-on initialization.
For engineers reviewing the MAX16059ATT30+ datasheet, MAX16059ATT30+ pinout, MAX16059ATT30+ application, or MAX16059ATT30+ equivalent, key selection criteria include its open-drain RESET output, absence of watchdog timer, automotive-grade -40°C to +125°C operation, and compatibility with low-leakage ceramic capacitors on SRT for precise reset timing control.
Technical Context
The MAX16059ATT30+ implements a precision voltage monitor with ±2.5% reset threshold tolerance over temperature and 0.5% hysteresis to prevent chatter during VCC recovery. Its internal ramp-based timing circuit uses SRT pin current (210–240nA) and threshold (1.173–1.297V) to generate reset timeout periods scalable via external capacitor (39pF–4.7µF).
As a member of the MAX16056–MAX16059 family, it shares BiCMOS process technology, 3mm × 3mm TDFN-EP package, and guaranteed RESET validity at VCC ≥ 1.1V. Unlike MAX16056/MAX16058 variants, it omits WDI, SWT, WDS, and N.C. pins - confirming no watchdog functionality and simplified 6-pin pinout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.000V (factory-trimmed, ±2.5% over -40°C to +125°C) - sets precise brownout detection point for 3.3V systems |
| Supply Current | 125nA typical at VCC = 1.8V, TA = +25°C - enables multi-year battery life in portable medical sensors |
| Operating Voltage | 1.1V to 5.5V - supports direct monitoring of Li-ion, coin-cell, and 3.3V/5V rails without external regulators |
| Reset Timeout | 10.5–17.0ms (with CSRT = 2700pF) - configurable via external capacitor to match µP reset hold requirements |
| Output Type | Open-drain RESET - allows level-shifting to different logic domains and wired-OR reset bus implementation |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| VCC to RESET Delay | 80µs - ensures fast response to supply collapse, critical for real-time safety-critical firmware |
Pinout & Package
Package: 6-pin TDFN-EP (3mm × 3mm, exposed pad), RoHS-compliant, thermal resistance θJA = 42°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RESET | Open-drain reset output | Asserts low during VCC undervoltage or MR activation; requires external pullup for logic-level compatibility |
| 2 GND | Ground reference | Primary return path for internal circuits and SRT/CSRT capacitor discharge |
| 3 MR | Manual reset input | Active-low asynchronous reset trigger; no internal pullup - must be tied to VCC if unused |
| 4 SRT | Reset timeout capacitor input | Connects to low-leakage ceramic capacitor (e.g., X7R) to set tRP = 5.15 × 10⁶ × CSRT seconds |
| 5 VCC | Supply and monitored rail | Power input and voltage sense node; bypass with 0.1µF ceramic capacitor to GND for noise immunity |
| 6 EP | Exposed thermal pad | Must be connected to GND for optimal thermal performance and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 125nA typical supply current enables >10-year battery life in always-on wearable sensors |
| Capacitor-adjustable tRP | SRT pin enables precise, field-tunable reset hold time (ms to seconds) without firmware changes |
| Valid RESET at low VCC | Guaranteed RESET assertion down to VCC = 1.1V prevents undefined µP state during deep brownout |
| Transient immunity | Immune to ≤40µs, 100mV VCC transients - eliminates false resets in noisy automotive/industrial power rails |
| Open-drain flexibility | Allows shared reset bus across multiple ICs and interface to 1.8V/2.5V/3.3V logic without level translators |
Applications
| Glucose Monitors | Patient Monitors |
|---|---|
Use Scenario: Continuous blood glucose sensing in handheld meters requiring stable startup after battery insertion or low-battery recovery. IC Role / Device Role / Timing Role: Supervisory circuit asserting RESET until VCC stabilizes above 3.000V and holds for ≥10.5ms to ensure ADC and RF subsystem initialization. Use Value: Prevents corrupted sensor readings or BLE transmission errors caused by premature µP execution during power ramp. | Use Scenario: Multi-parameter bedside monitors powered by backup batteries during AC mains failure. IC Role / Device Role / Timing Role: Brownout detector triggering system-wide reset when main 5V rail drops below 3.000V, with adjustable timeout matching display controller wake-up latency. Use Value: Eliminates display freeze or parameter loss by enforcing deterministic restart before analog front-end drifts out of spec. |
| Metering (Smart Meters) | HVAC Controllers |
Use Scenario: Tamper-resistant electricity/water meters operating on primary lithium batteries with 15+ year lifespan. IC Role / Device Role / Timing Role: Low-current supervisor enabling periodic wake-up cycles; open-drain RESET controls power-gating MOSFET to cut µP supply between readings. Use Value: Reduces average system current to <1µA during sleep, extending battery life while maintaining secure boot integrity. | Use Scenario: Embedded HVAC control units exposed to wide ambient temperatures (-40°C to +85°C) and line-voltage fluctuations. IC Role / Device Role / Timing Role: Automotive-grade supervisor ensuring reliable µP reset during cold cranking (VCC dip to 2.8V) and hot idle (125°C junction). Use Value: Prevents lockup or erratic valve actuation by guaranteeing RESET assertion for full timeout even at temperature extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16057ATT30+ | Push-pull RESET output (vs. open-drain); identical reset threshold, timing, and package | Requires no external pullup; unsuitable for wired-OR reset buses or mixed-voltage systems | Select when driving single µP with matched VCC logic levels and no bus sharing needed |
| TPS3808G30DBVR | 3.0V threshold, 1.6µA ICC (vs. 125nA), SOT-23-6 package, fixed 200ms timeout | Lacks capacitor-adjustable reset timeout; higher quiescent current limits battery lifetime | Select when board space is constrained and fixed long timeout suffices for non-battery applications |
Compared with MAX16057ATT30+, the MAX16059ATT30+ enables shared reset busing and level translation but requires external pullup; compared with TPS3808G30DBVR, it delivers 13× lower supply current and field-configurable timing at the cost of larger TDFN footprint.

FAQ
What is the factory-trimmed reset threshold voltage of the MAX16059ATT30+?
The MAX16059ATT30+ has a factory-trimmed reset threshold of 3.000V, with ±1.5% tolerance at +25°C and ±2.5% over the full -40°C to +125°C operating range. This value is confirmed in Table 1 of the datasheet under suffix "30", and applies specifically to the MAX16059ATT30+ variant - not extrapolated from adjacent thresholds.
Does the MAX16059ATT30+ include a watchdog timer function?
No, the MAX16059ATT30+ does not include a watchdog timer. As stated in the General Description and Pin Configurations, only MAX16056/MAX16058 variants feature watchdog inputs (WDI, SWT, WDS); the MAX16059ATT30+ is a 6-pin device omitting those pins and associated circuitry - confirmed by its pinout table and ordering information.
What package type and dimensions does the MAX16059ATT30+ use?
The MAX16059ATT30+ uses a 6-pin TDFN-EP package measuring 3mm × 3mm with an exposed thermal pad (EP). This is explicitly documented in the Package Information section and Typical Operating Circuit diagram, and matches land pattern number 90-0058 per Analog Devices' package database.
How is the reset timeout period configured on the MAX16059ATT30+?
The reset timeout period on the MAX16059ATT30+ is configured by connecting a low-leakage ceramic capacitor (e.g., X7R) between the SRT pin and GND. The relationship is tRP = 5.15 × 10⁶ × CSRT seconds - for example, 2700pF yields 14.18ms. This formula and recommended capacitor range (39pF–4.7µF) are specified in the Pin Description and Applications Information sections.
What is the maximum supply voltage rating for the MAX16059ATT30+?
The MAX16059ATT30+ has an absolute maximum VCC rating of +6V, with operational range specified from 1.1V to 5.5V. This is stated in both the Absolute Maximum Ratings table (VCC to GND: -0.3V to +6V) and Electrical Characteristics (Supply Voltage MIN/MAX: 1.1V/5.5V), and applies across the full temperature range.
