Product details
Overview
MAX16057ATT17+T from Analog Devices is a nanoPower microprocessor supervisory circuit in a 6-pin TDFN package, monitoring single-supply VCC (1.1V–5.5V) and asserting active-low reset when voltage drops below factory-trimmed 1.665V threshold, manual reset is triggered, or watchdog timeout occurs - though MAX16057 lacks watchdog functionality. It delivers ultra-low 125nA typical supply current and supports capacitor-adjustable reset timeout (e.g., 14.18ms with 2700pF), enabling reliable power-up/brownout protection in battery-powered medical and portable electronics.
For engineers reviewing the MAX16057ATT17+T datasheet, MAX16057ATT17+T pinout, MAX16057ATT17+T application, or MAX16057ATT17+T equivalent, key selection criteria include its 1.665V reset threshold tolerance (±2.5% over −40°C to +125°C), push-pull RESET output with guaranteed validity down to VCC = 1.1V, adjustable reset timeout via SRT capacitor, absence of watchdog timer, and automotive-grade temperature operation.
Technical Context
The MAX16057ATT17+T implements a precision bandgap-based voltage monitor with hysteresis (0.5%) and an internal ramp-and-compare timing architecture for reset timeout generation. Its SRT pin uses a controlled 240nA (typ) ramp current charging an external capacitor to set tRP = 5.15 × 10⁶ × CSRT (seconds), ensuring predictable delay independent of VCC within 1.1V–5.5V range.
Unlike MAX16056/MAX16058 variants, MAX16057ATT17+T omits WDI, SWT, WDS, and N.C. pins - confirming no watchdog capability and simplified 6-pin topology. The device guarantees RESET assertion for VCC ≥ 1.1V and exhibits transient immunity up to 40µs for 100mV overdrive, critical for noisy automotive and industrial supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 125nA typical at VCC = 1.8V, TA = −40°C to +125°C - enables multi-year battery life in always-on medical monitors. |
| Reset Threshold | 1.665V (typ), ±2.5% over −40°C to +125°C - factory-trimmed for precise brownout detection without external resistors. |
| Operating Voltage | 1.1V to 5.5V - supports direct interface with 1.2V, 1.8V, 3.3V, and 5V logic domains without level shifting. |
| Reset Timeout | Adjustable from ~10.5ms to >24s via SRT capacitor (e.g., 2700pF → 14.18ms) - accommodates diverse µP initialization sequences. |
| Output Type | Push-pull RESET - drives high/low actively, eliminating need for external pullup and simplifying PCB layout. |
| Temperature Range | −40°C to +125°C - fully specified for automotive under-hood and industrial control applications. |
| Hysteresis | 0.5% - prevents reset chatter during slow VCC recovery near threshold. |
Pinout & Package
MAX16057ATT17+T is housed in a 3mm × 3mm, 0.8mm height, 6-pin TDFN-EP package with exposed pad (EP) recommended to be connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RESET | Active-low push-pull reset output | Asserts low on VCC drop below 1.665V, MR low, or timeout; remains low for tRP after recovery - directly interfaces µP RESET pin. |
| 2 GND | Ground reference | Primary return path for internal circuits and SRT/SWT capacitor discharge; connects to EP for optimal thermal conduction. |
| 3 MR | Manual reset input | CMOS-compatible active-low input; no internal pullup - must be tied to VCC if unused or driven by switch/pullup. |
| 4 SRT | Reset timeout capacitor input | Accepts external capacitor (39pF–4.7µF) to set tRP; internal 240nA ramp current ensures accurate, VCC-independent timing. |
| 5 VCC | Supply and monitored voltage input | Powers device and serves as monitored rail; requires 0.1µF bypass to GND; valid RESET guaranteed down to 1.1V. |
| 6 EP | Exposed thermal pad | Not electrically connected; soldered to GND plane for thermal dissipation (θJC = 9°C/W) and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 125nA typical supply current enables >10-year battery life in glucose meters and portable diagnostics. |
| Capacitor-adjustable tRP | SRT pin allows precise, resistor-free reset timeout tuning across 10ms–24s range using standard ceramic capacitors. |
| Guaranteed RESET validity | RESET output remains functional and well-defined down to VCC = 1.1V - critical for low-voltage SoC power sequencing. |
| High noise immunity | Withstands 40µs transients at 100mV overdrive - eliminates false resets in automotive and industrial environments. |
| Automotive qualification | Specified over −40°C to +125°C with AEC-Q100 stress testing - suitable for engine control, ADAS sensors, and infotainment. |
Applications
| Glucose Monitors | 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+T | Higher reset threshold (2.313V typ); identical 6-pin TDFN, push-pull, no watchdog. | Suitable for 2.5V/3.3V systems where 1.665V threshold is too low to avoid false resets. | Select when monitoring higher VCC rails; same footprint and timing behavior - only threshold differs. |
| TLV803EB29DBVR | Fixed 2.93V threshold, 350nA ICC, SOT-23-3 package, no adjustable timeout, no MR input. | Limited to simple reset-only use cases without manual reset or programmable delay. | Choose for cost-sensitive, space-constrained designs needing basic reset only - sacrifices adjustability and MR flexibility. |
Compared with MAX16057ATT23+T and TLV803EB29DBVR, MAX16057ATT17+T uniquely balances ultra-low power (125nA), precise 1.665V threshold for low-voltage systems, capacitor-adjustable reset timing, and manual reset support - making it optimal for battery-powered medical and portable equipment where both accuracy and configurability are essential.

FAQ
What is the factory-trimmed reset threshold voltage of MAX16057ATT17+T?
The MAX16057ATT17+T has a factory-trimmed reset threshold voltage of 1.665V (typical), with tolerance of ±1.5% 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 "17", and applies exclusively to the MAX16057ATT17+T variant - not to other suffixes or family members like MAX16056.
Does MAX16057ATT17+T include a watchdog timer function?
No, MAX16057ATT17+T does not include a watchdog timer. As explicitly stated in the General Description and Typical Operating Circuit tables, only MAX16056 and MAX16058 variants feature watchdog functionality. MAX16057ATT17+T is a dedicated supervisory circuit with reset monitoring and adjustable timeout only - confirmed by its 6-pin pinout omitting WDI, SWT, and WDS terminals.
What package type and dimensions does MAX16057ATT17+T use?
MAX16057ATT17+T uses a 6-pin TDFN-EP (Thin Dual Flat No-lead with Exposed Pad) package measuring 3mm × 3mm × 0.8mm. The exposed pad (EP) is thermally and electrically isolated but recommended to be soldered to GND for improved thermal performance and EMI suppression - per Package Information section and land pattern 90-0058.
How is the reset timeout period adjusted on MAX16057ATT17+T?
The reset timeout period on MAX16057ATT17+T is adjusted by connecting an external capacitor between the SRT pin and GND. The relationship is tRP = 5.15 × 10⁶ × CSRT (seconds), so a 2700pF capacitor yields 14.18ms. Ceramic X7R capacitors from 39pF to 4.7µF are recommended, and the SRT pin uses a precision 240nA (typ) internal ramp current to ensure VCC-independent timing accuracy.
Is MAX16057ATT17+T qualified for automotive applications?
Yes, MAX16057ATT17+T is fully specified and tested over the −40°C to +125°C automotive temperature range, and its datasheet explicitly states compliance with automotive requirements. While not AEC-Q100 certified in this revision, its electrical characteristics, thermal specs (θJA = 42°C/W), and application notes confirm suitability for under-dash and engine-compartment-adjacent systems such as body control modules and sensor nodes.
