Product details
Overview
MAX6716AUTSYD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 6-pin SOT23 package, monitoring VCC1 (4.625V factory-trimmed threshold) and VCC2 (3.075V threshold) with 210ms reset timeout, push-pull active-low RST output, and guaranteed reset validity down to VCC = 0.8V. It supports telecom power systems requiring precise dual-rail monitoring and brownout protection.
For engineers reviewing the MAX6716AUTSYD3+ datasheet, MAX6716AUTSYD3+ pinout, MAX6716AUTSYD3+ application, or MAX6716AUTSYD3+ equivalent, this page delivers verified electrical specs, exact pin functions, real-world use cases in multivoltage embedded systems, and two validated alternative parts with documented functional differences.
Technical Context
The MAX6716AUTSYD3+ implements dual independent voltage comparators with internal 4.625V and 3.075V thresholds referenced to VCC1 and VCC2 respectively, each feeding a shared reset timeout timer (210ms min). Its push-pull RST output is referenced to VCC1 and asserts low when either supply falls below its threshold or MR is pulled low.
It includes a manual-reset input (MR) with internal 50kΩ pullup to VCC1, 1µs minimum pulse width, and 200ns MR-to-reset delay. The device operates across -40°C to +125°C and draws only 10µA typical supply current at 3.6V, enabling use in battery-sensitive industrial controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (factory-trimmed, ±125mV tolerance), ensures reliable reset assertion for 5V logic rails during brownout |
| VCC2 Reset Threshold | 3.075V (factory-trimmed, ±75mV tolerance), matches common 3.3V I/O supply monitoring requirement |
| Reset Timeout Period | 210ms (minimum), provides sufficient hold time for full μP initialization after power recovery |
| Supply Current | 10µA typical at 3.6V, enables >10-year battery life in always-on monitoring applications |
| Operating Temperature | -40°C to +125°C, qualified for under-hood automotive and industrial control environments |
| Reset Output Type | Push-pull active-low RST, eliminates need for external pullup and drives directly into μP reset pin |
| VCC Validity Guarantee | Reset logic valid down to VCC1 or VCC2 = 0.8V, ensures deterministic behavior during deep brownout |
Pinout & Package
Package: 6-pin SOT23 (2.9mm × 1.6mm × 1.1mm height), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low reset output | Push-pull driver referenced to VCC1; asserts low on VCC1/VCC2 undervoltage, MR low, or watchdog timeout |
| 2 - GND | Ground reference | Common return path for all internal comparators, timers, and output drivers |
| 3 - MR | Manual-reset input | Active-low input with internal 50kΩ pullup to VCC1; 1µs minimum pulse width, 200ns response delay |
| 4 - VCC2 | Secondary supply input | Powers internal VCC2 comparator and sets secondary reset threshold (3.075V); must be ≥0.8V for valid operation |
| 5 - VCC1 | Primary supply input | Powers core logic and primary comparator (4.625V threshold); supplies RST output stage |
| 6 - NC | No connect | Unused pin; must remain unconnected per datasheet to avoid undefined behavior |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed voltage monitoring | Simultaneous 4.625V (VCC1) and 3.075V (VCC2) thresholds eliminate external resistor dividers and calibration |
| 210ms minimum reset timeout | Guarantees μP reset hold time exceeds boot sequence duration in ARM Cortex-M and similar MCUs |
| Push-pull RST output | Drives reset line directly without external pullup, reducing BOM count and PCB area in space-constrained designs |

IC Role / Device Role / Timing Role: Dual-rail supervisor ensuring 5V analog front-end and 3.3V digital core power up in correct order and remain stable. Use Value: 10µA quiescent current extends single-charge battery runtime while preventing corrupted image acquisition due to premature release of reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUTLTD3+ | Same 6-pin SOT23 package and 210ms timeout, but VCC1 threshold = 4.500V (L suffix) and VCC2 = 3.000V (T suffix) | Lower VCC1 threshold better suits 4.5V nominal rails; identical timing and pinout enable drop-in replacement where 4.5V trip is preferred | Select when system requires earlier reset assertion on 4.5V supply sag, with no layout or firmware changes needed |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only), 200ms timeout, SOT23-6 package, 1.8µA typical ICC | Lacks VCC2 monitoring capability; requires separate IC or redesign to monitor second rail | Choose only for single-rail systems; not suitable for dual-voltage monitoring without adding components |
Compared with MAX6716AUTSYD3+, MAX6715AUTLTD3+ offers identical form-factor and timing but shifts VCC1 trip point downward by 125mV-critical for tighter 4.5V margin systems-while TPS3808G33DBVR reduces current consumption by 80% but sacrifices dual-rail functionality entirely.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6716AUTSYD3+?
The MAX6716AUTSYD3+ has a factory-trimmed VCC1 reset threshold of 4.625V (±125mV), corresponding to the 'S' suffix in the Reset Voltage Threshold Suffix Guide. This value is guaranteed over -40°C to +125°C and ensures reliable detection of brownout on 5V nominal rails. The MAX6716AUTSYD3+ datasheet specifies this as the typical falling threshold with 0.5% hysteresis.
Does the MAX6716AUTSYD3+ support monitoring a third voltage rail?
No, the MAX6716AUTSYD3+ is a dual-supply supervisor and does not include RSTIN or PFI inputs. It monitors only VCC1 and VCC2. For triple-voltage monitoring, consider MAX6719AUTSYD3+ (with RSTIN) or MAX6728AKASD3+ (with PFI/PFO). The MAX6716AUTSYD3+ pinout omits RSTIN, PFI, and PFO terminals, confirming its dual-rail-only function.
What is the reset timeout period of the MAX6716AUTSYD3+ and how is it set?
The MAX6716AUTSYD3+ has a minimum reset timeout period of 210ms, indicated by the 'D3' suffix in its part number. This value is factory-programmed and non-adjustable. The timeout begins when VCC1 or VCC2 falls below threshold and holds RST low for ≥210ms after both supplies recover above their thresholds, ensuring full μP initialization before release.
Is the MAX6716AUTSYD3+ pin-compatible with other parts in the MAX6715A–MAX6729A family?
Yes, the MAX6716AUTSYD3+ shares the same 6-pin SOT23 package and pinout as MAX6715A/MAX6717A/MAX6719A variants. Pin 1 is RST, Pin 2 is GND, Pin 3 is MR, Pin 4 is VCC2, Pin 5 is VCC1, and Pin 6 is NC. However, functional differences exist-e.g., MAX6717A uses open-drain RST and lacks push-pull drive-so electrical compatibility must be verified per application.
What is the supply current specification for the MAX6716AUTSYD3+ at 3.6V?
The MAX6716AUTSYD3+ draws 10µA typical supply current at 3.6V with all I/O connections open and outputs not asserted, as specified in the Electrical Characteristics table. This ultra-low ICC enables deployment in battery-powered equipment where multi-year operation is required, and the value is measured across -40°C to +125°C with <39µA maximum at full temperature range.
