Product details
Overview
MAX16059ATT17+T from Analog Devices is a 6-pin TDFN ultra-low-power microprocessor supervisory circuit with factory-trimmed 1.665V reset threshold, 125nA typical supply current, capacitor-adjustable reset timeout (14.18ms with 2700pF), and no watchdog timer. It provides push-pull active-low RESET output and operates across -40°C to +125°C for battery-powered medical and portable electronics.
For engineers reviewing the MAX16059ATT17+T datasheet, MAX16059ATT17+T pinout, MAX16059ATT17+T application, or MAX16059ATT17+T equivalent, key selection criteria include reset threshold accuracy (±2.5% over temperature), guaranteed RESET validity down to VCC = 1.1V, open-drain/push-pull output configuration, and compatibility with low-leakage ceramic timing capacitors (SRT/CSRT).
Technical Context
The MAX16059ATT17+T implements a precision bandgap-based voltage monitor with 0.5% hysteresis and internal ramp-current timing architecture for capacitor-adjusted reset timeout. Its SRT input uses a 240nA (typ) ramp current charging an external capacitor to generate the reset delay period.
Unlike the MAX16056/MAX16058 variants, this device omits WDI, WDS, and SWT pins-confirming absence of watchdog functionality. The 6-pin TDFN-EP package integrates GND-connected exposed pad for thermal performance and EMI reduction in space-constrained automotive and medical PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 125nA typ at VCC = 1.8V, TA = +25°C - enables multi-year operation on coin-cell batteries |
| Reset Threshold | 1.665V (typ), ±2.5% over -40°C to +125°C - matches 1.8V system brownout detection |
| Reset Timeout | 14.18ms (typ) with 2700pF SRT capacitor - ensures reliable µP initialization after power recovery |
| Operating Range | VCC = 1.1V to 5.5V - supports single-supply operation from Li-ion down to partially discharged cells |
| Output Type | Push-pull active-low RESET - eliminates need for external pullup resistor in most µP interfaces |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive and industrial embedded use |
Pinout & Package
MAX16059ATT17+T uses a 6-pin 3mm × 3mm TDFN-EP package with exposed pad (EP) connected to GND for thermal and EMI performance. Pin 1 is RESET; Pin 2 is GND; Pin 3 is MR; Pin 4 is SRT; Pin 5 is VCC; Pin 6 is N.C. (no internal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Active-low reset output | Push-pull driver guarantees valid logic level without external pullup; sinks 50µA at 0.3V VOL |
| 2 - GND | Ground reference | Primary return path for internal bias and timing currents; connects to EP for thermal conduction |
| 3 - MR | Manual reset input | CMOS-compatible input with 200ns glitch rejection; asserts RESET when pulled low |
| 4 - SRT | Reset timeout capacitor terminal | Connects to GND via low-leakage ceramic capacitor (e.g., 2700pF X7R) to set tRP = 5.15×10⁶ × CSRT |
| 5 - VCC | Supply and monitored voltage | Input for both power and VTH comparison; requires 0.1µF bypass to GND for noise immunity |
| 6 - N.C. | No connection | Not internally bonded; must remain unconnected per datasheet to avoid malfunction |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 125nA typical supply current enables >10-year battery life in glucose monitors |
| Factory-trimmed VTH | 1.665V threshold with ±2.5% tolerance over full automotive temperature range |
| Capacitor-adjustable tRP | External SRT capacitor sets reset timeout from 10.5ms to 17.0ms (2700pF yields 14.18ms) |
| VCC ≥ 1.1V RESET guarantee | Ensures deterministic reset assertion even during deep brownout conditions |
| Transient immunity | Rejects ≤40µs, 100mV VCC transients - critical for noisy automotive power rails |
Applications
| Portable Medical Devices | Battery-Powered IoT Sensors |
|---|---|
Use Scenario: Glucose meters and patient monitors powered by CR2032 coin cells requiring multi-year shelf life and reliable power-on reset. IC Role / Device Role / Timing Role: Supervisory circuit asserting active-low RESET until VCC stabilizes above 1.665V and holds it for 14.18ms post-recovery. Use Value: Prevents firmware execution errors during battery insertion or voltage sag; 125nA ICC extends usable battery life beyond 5 years. | Use Scenario: Wireless environmental sensors deployed in remote locations with infrequent maintenance and no access to recharge. IC Role / Device Role / Timing Role: Voltage monitor ensuring µP only boots when supply exceeds 1.665V and remains stable for capacitor-defined timeout. Use Value: Eliminates false wakeups from transient dips; push-pull output reduces BOM count by removing external pullup resistor. |
| Automotive Body Electronics | Industrial Handheld Terminals |
Use Scenario: Door module controllers exposed to load-dump and cold-crank conditions where VCC may dip below 2.0V. IC Role / Device Role / Timing Role: Brownout detector with guaranteed RESET assertion down to VCC = 1.1V and -40°C to +125°C operation. Use Value: Maintains system integrity during engine start; 0.5% hysteresis prevents chatter near threshold during slow VCC recovery. | Use Scenario: Ruggedized barcode scanners used in warehouses with variable ambient temperatures and mechanical shock. IC Role / Device Role / Timing Role: Power supervisor providing manual-reset capability via front-panel button and precise reset timing. Use Value: MR input with 1µs minimum pulse width allows direct switch interface; 6-pin TDFN saves PCB area versus SOIC alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16057ATT17+T | Identical pinout, same 1.665V threshold and 6-pin TDFN, but push-pull RESET output (same as MAX16059ATT17+T) | No functional difference - MAX16057ATT17+T and MAX16059ATT17+T share identical supervisory functionality and timing specs | Select MAX16057ATT17+T if top-mark traceability or legacy BOM alignment is required; electrically interchangeable |
| TPS3808G16DBVR | 1.6V threshold, 1.8µA ICC (14× higher), SOT-23-6 package, fixed 200ms reset timeout, no capacitor adjustment | Suitable for cost-sensitive, non-battery-critical applications where longer fixed timeout is acceptable | Choose only if ultra-low ICC is not required; incompatible timing flexibility and higher quiescent current limits battery-life-critical designs |
Compared with MAX16057ATT17+T, the MAX16059ATT17+T offers identical electrical behavior but distinct top-mark and ordering code; versus TPS3808G16DBVR, it delivers 14× lower supply current and field-adjustable reset timeout-critical for energy-constrained medical and portable systems.

FAQ
What is the factory-trimmed reset threshold voltage for MAX16059ATT17+T?
The MAX16059ATT17+T has a factory-trimmed reset threshold voltage of 1.665V (typical), with ±2.5% tolerance over the full -40°C to +125°C operating temperature range. This value corresponds to the "17" suffix in the part number per Table 1 of the datasheet, and is optimized for 1.8V system monitoring with margin against brownout.
Does MAX16059ATT17+T include a watchdog timer function?
No, the MAX16059ATT17+T does not include a watchdog timer. As confirmed in the Ordering Information table and Pin Description section, MAX16059 variants lack WDI, WDS, and SWT pins. Only MAX16056 and MAX16058 include watchdog functionality; MAX16059ATT17+T is a reset-only supervisory circuit.
What capacitor value sets the standard reset timeout for MAX16059ATT17+T?
A 2700pF capacitor connected between the SRT pin and GND sets the standard reset timeout of 14.18ms (typical) for MAX16059ATT17+T. This value is explicitly listed in the Electrical Characteristics table under "Reset Timeout Period (tRP)" and verified in Table 2 of the datasheet.
Is MAX16059ATT17+T compatible with 1.1V supply rails?
Yes, MAX16059ATT17+T operates with VCC as low as 1.1V and guarantees valid RESET output down to that voltage. The datasheet specifies "Guaranteed RESET Valid for VCC ≥ 1.1V", making it suitable for deeply discharged battery scenarios where other supervisors fail to assert reset reliably.
What is the package type and thermal specification for MAX16059ATT17+T?
MAX16059ATT17+T uses a 6-pin 3mm × 3mm TDFN-EP package with exposed pad (EP). Its junction-to-ambient thermal resistance (θJA) is 42°C/W, and junction-to-case (θJC) is 9°C/W, measured per JEDEC JESD51-7 on a four-layer board - enabling reliable operation at +125°C ambient with proper PCB copper pour under the EP.
