Product details
Overview
MAX16057ATT17+ from Analog Devices is a nanoPower microprocessor supervisory circuit in a 6-pin TDFN package, designed to monitor a single supply voltage and assert an active-low reset when VCC drops below the factory-trimmed 1.665V threshold (±2.5% over temperature), with ultra-low 125nA typical supply current at 3.3V and -40°C to +125°C operation. It supports capacitor-adjustable reset timeout (e.g., 14.18ms with 2700pF) and includes manual reset input (MR), push-pull RESET output, and guaranteed RESET validity down to VCC = 1.1V - used in glucose monitors and battery-powered medical devices.
For engineers reviewing the MAX16057ATT17+ datasheet, MAX16057ATT17+ pinout, MAX16057ATT17+ application, or MAX16057ATT17+ equivalent, key selection criteria include its watchdog-free design (distinguishing it from MAX16056/MAX16058), 6-pin TDFN-EP footprint, 1.665V reset threshold, adjustable reset timeout via SRT capacitor, and automotive-grade temperature range compliance.
Technical Context
The MAX16057ATT17+ implements a precision voltage-monitoring architecture with internal hysteresis (0.5%) and a ramp-based timing circuit for capacitor-adjusted reset timeout. Its reset assertion is triggered solely by VCC falling below the trimmed threshold or MR pull-down - no watchdog logic is present, eliminating WDI, SWT, WDS, and N.C. pins found on related variants.
It features guaranteed RESET output validity down to VCC = 1.1V, power-supply transient immunity (e.g., ≤40µs for 100mV overdrive), and CMOS-compatible input thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC). The push-pull RESET output delivers VOL ≤ 0.3V at 50µA sink and VOH ≥ 0.8×VCC at 200µA source, enabling direct interface with low-voltage µPs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.665V (typ), ±2.5% over -40°C to +125°C - sets precise brownout detection point for 1.8V systems |
| Supply Current | 125nA (typ) at 3.3V, -40°C to +125°C - enables multi-year battery life in portable medical devices |
| Operating Voltage | 1.1V to 5.5V - supports operation during deep brownout and compatibility with 1.2V–5V rails |
| Reset Timeout | Adjustable via SRT capacitor (e.g., 14.18ms with 2700pF) - ensures µP initialization completes before release |
| Output Type | Push-pull RESET - eliminates need for external pull-up resistor, reducing BOM count and leakage risk |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| Hysteresis | 0.5% - prevents chatter during slow VCC recovery near threshold |
Pinout & Package
The MAX16057ATT17+ uses a 6-pin 3mm × 3mm TDFN-EP package with exposed pad (EP) recommended to be connected to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RESET | Active-low push-pull reset output | Asserts low during VCC undervoltage or MR activation; deasserts after capacitor-set timeout - directly drives µP RESET pin without pull-up |
| 2 GND | Ground reference | Primary return path for all internal circuits and RESET sink current; EP connection enhances thermal dissipation |
| 3 MR | Manual reset input | CMOS-compatible active-low input; no internal pull-up - must be tied to VCC if unused to prevent floating |
| 4 SRT | Reset timeout capacitor input | Connects to external capacitor (39pF–4.7µF) to set tRP = 5.15×10⁶ × CSRT seconds - enables precise power-on reset timing |
| 5 VCC | Supply and monitored voltage input | Powers device and serves as monitored rail; requires 0.1µF bypass capacitor to GND for noise immunity |
| 6 EP | Exposed thermal pad | Not electrically connected; soldered to PCB GND plane for improved thermal resistance (θJC = 9°C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 125nA typical supply current enables >10-year battery life in coin-cell-powered patient monitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16057ATT23+ | Higher reset threshold (2.313V typ), identical pinout, package, and feature set | Targeted at 2.5V/3.3V systems instead of 1.8V rails; same medical/industrial use cases | Select when system VCC nominal is ≥2.3V and brownout margin must exceed 10% |
| TPS3808G16DBVR | 1.6V threshold (±0.5%), 1.5µA IQ, SOT-23-6 package, no adjustable timeout - fixed 200ms delay | Lacks capacitor-adjustable reset timeout; higher supply current limits battery life in ultra-low-power designs | Choose only if fixed delay suffices and board space permits SOT-23; not suitable for long-life coin-cell applications |

FAQ
What is the exact reset threshold voltage of the MAX16057ATT17+?
The MAX16057ATT17+ 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 is confirmed by the "17" suffix in the part number per Table 1 of the datasheet and is laser-trimmed during production for precision brownout detection in 1.8V systems.
Does the MAX16057ATT17+ include a watchdog timer function?
No, the MAX16057ATT17+ does not include a watchdog timer. It is explicitly defined in the datasheet as a watchdog-free variant within the MAX16056–MAX16059 family. Unlike MAX16056/MAX16058, the MAX16057ATT17+ omits WDI, SWT, and WDS pins and contains no watchdog circuitry - simplifying design for applications requiring only voltage supervision and manual reset.
What package type and dimensions does the MAX16057ATT17+ use?
The MAX16057ATT17+ uses a 6-pin TDFN-EP (Thin Dual Flat No-lead with Exposed Pad) package measuring 3mm × 3mm with 0.5mm pitch. The exposed pad (EP) is thermally and electrically connected to GND per datasheet recommendation, and the package outline is documented under land pattern 90-0058 on analog.com/packages.
How is the reset timeout period configured on the MAX16057ATT17+?
The reset timeout period on the MAX16057ATT17+ is configured using an external capacitor connected between the SRT pin and GND. The relationship is tRP = 5.15 × 10⁶ × CSRT (seconds), where CSRT is in farads - for example, a 2700pF capacitor yields 14.18ms. Ceramic X7R capacitors are recommended for low leakage and temperature stability.
What is the minimum operating supply voltage for guaranteed RESET functionality in the MAX16057ATT17+?
The MAX16057ATT17+ guarantees valid RESET output functionality down to VCC = 1.1V, as specified in the Electrical Characteristics table. Below this voltage, RESET sink/source capability degrades significantly; however, the device continues asserting RESET until VCC falls below 1.1V, ensuring fail-safe behavior during deep brownout conditions in medical and industrial systems.
