Product details
Overview
MAX16058ATA44+ from Analog Devices is an ultra-low-power microprocessor supervisory IC with open-drain RESET output, factory-trimmed 4.375V reset threshold (±2.5% over -40°C to +125°C), capacitor-adjustable reset timeout (10.5–17.0ms typical with 2700pF), and integrated watchdog timer with 128× extended mode. It monitors single-supply systems in battery-powered medical and portable electronics where supply current ≤125nA (typ) and VCC operation down to 1.1V are critical.
For engineers reviewing the MAX16058ATA44+ datasheet, MAX16058ATA44+ pinout, MAX16058ATA44+ application, or MAX16058ATA44+ equivalent, this page delivers verified technical context, exact pin functions for TDFN-8EP layout, real-world timing behavior under temperature variation, and two validated alternative parts with documented functional trade-offs - all aligned to automotive-grade (-40°C to +125°C) operation and nanoPower system design requirements.
Technical Context
The MAX16058ATA44+ implements a precision voltage monitor with hysteresis (0.5%) and a dual-capacitor-timed architecture: SRT sets reset timeout via ramp-current charging (210–240nA), while SWT and WDS jointly configure watchdog timeout (normal or 128× extended mode). Its open-drain RESET output guarantees valid logic down to VCC = 1.1V and supports external pullup to any rail ≤5.5V.
It features active-low manual reset (MR) with 250ns delay, glitch rejection (200ns), and watchdog input (WDI) sensitive to falling edges ≥150ns. The device samples SWT capacitance after RESET deassertion and disables watchdog if CSWT < 470pF (continuous reset) or > 0.47µF (infinite timeout), enabling robust fault detection in low-duty-cycle embedded systems.
Key Specifications

Pinout & Package
MAX16058ATA44+ uses an 8-pin 3mm × 3mm TDFN-EP package with exposed pad (EP) that must be connected to GND for thermal and electrical performance. Pin 1 is marked by a dot; EP is electrically tied to GND internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RESET | Open-drain reset output | Asserts low on VCC drop below 4.375V, MR low, or watchdog timeout; requires external pullup |
| 2 GND | Ground reference | Primary return path for internal circuitry and EP connection point |
| 3 SWT | Watchdog timeout capacitor input | Connects to GND via CSWT (2275pF–0.54µF) to set base watchdog period; grounded to disable |
| 4 MR | Manual reset input | Active-low asynchronous reset trigger; no internal pullup - must tie to VCC if unused |
| 5 SRT | Reset timeout capacitor input | Connects to GND via CSRT (39pF–4.7µF) to set reset hold time after VCC recovery |
| 6 WDS | Watchdog select input | GND = normal mode; VCC = 128× extended timeout; transition clears watchdog counter |
| 7 WDI | Watchdog input | Falling edge resets watchdog timer; pulse width ≥150ns required for reliable detection |
| 8 VCC | Supply and monitored voltage | Input for both power and VCC monitoring; bypass with 0.1µF ceramic capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 125nA typical supply current enables >10-year coin-cell operation in portable medical devices |
| Capacitor-adjustable tRP | SRT pin uses linear ramp current (210–240nA) to achieve precise, temperature-stable reset timeout without trimming |
| Watchdog with WDS scaling | WDS pin selects 1× or 128× multiplier on SWT-set timeout - eliminates need for large capacitors in long-interval monitoring |
| VCC transient immunity | Immune to 100mV transients ≤40µs duration - prevents spurious resets during noisy power-up sequences |
| Guaranteed RESET validity | RESET remains functional down to VCC = 1.1V - ensures deterministic reset before µP enters undefined state |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16056ATA44+ | Push-pull RESET output; identical reset threshold, timeout, and watchdog specs | Requires no external pullup; unsuitable for wired-OR reset buses or level-shifting | Select when driving CMOS inputs directly and board space permits simpler routing |
| TLV803EC43DBVR | Fixed 4.3V threshold; no watchdog; 1.8µA supply current; SOT-23-5 package | Lacks capacitor-adjustable timing and system-level fault detection capability | Choose for cost-sensitive, non-safety-critical applications where only basic reset is needed |
Compared with MAX16058ATA44+, MAX16056ATA44+ offers identical supervision accuracy and timing but eliminates external pullup components at the cost of bus-sharing flexibility, while TLV803EC43DBVR trades nanoPower operation and watchdog intelligence for lower unit cost and smaller footprint in simple reset-only designs.

FAQ
What is the factory-trimmed reset threshold voltage for MAX16058ATA44+?
The MAX16058ATA44+ has a factory-trimmed reset threshold of 4.375V (typical), with tolerance of ±2.5% over the full -40°C to +125°C operating temperature range. This value corresponds to the "44" suffix per Table 1 in the datasheet and is laser-trimmed during production to ensure accuracy without external calibration. The hysteresis is 0.5%, providing noise immunity during voltage recovery.
Does MAX16058ATA44+ include a watchdog timer, and how is it configured?
Yes, MAX16058ATA44+ includes a configurable watchdog timer. It is enabled by connecting a capacitor (CSWT) between SWT and GND, with timeout determined by CSWT value and WDS pin state: WDS = GND gives normal mode (5–9.5ms), WDS = VCC gives 128× extended mode (up to 296s). The watchdog is cleared by falling edges on WDI or transitions on WDS, and disabled by grounding SWT.
What package type and pin count does MAX16058ATA44+ use?
MAX16058ATA44+ uses an 8-pin 3mm × 3mm TDFN-EP (Thin Dual Flat No-lead with Exposed Pad) package. Pin 1 is marked by a dot; the exposed pad (EP) must be soldered to a GND plane for optimal thermal performance and electrical stability. This compact RoHS-compliant package supports high-density PCB layouts in space-constrained portable equipment.
How is the reset timeout period adjusted on MAX16058ATA44+?
The reset timeout period on MAX16058ATA44+ is adjusted using an external capacitor (CSRT) connected between the SRT pin and GND. The relationship is tRP = 5.15 × 10⁶ × CSRT (tRP in seconds, CSRT in farads). For example, a 2700pF capacitor yields 14.18ms typical timeout. Ceramic X7R capacitors are recommended for low leakage (<10nA) and stable temperature performance.
What is the maximum supply voltage and minimum operating voltage for MAX16058ATA44+?
MAX16058ATA44+ operates from VCC = 1.1V to 5.5V. The absolute maximum rating is -0.3V to +6V, but functional operation is guaranteed only within the 1.1V–5.5V range. Below 1.1V, RESET output sink capability degrades significantly; above 5.5V, permanent damage may occur. The device maintains valid RESET assertion down to 1.1V, ensuring reliable supervision during deep brownout conditions.
