Product details
Overview
The MAX6716AUTLTD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (4.625V threshold) and VCC2 (3.075V threshold) with 210ms (typ) reset timeout, push-pull active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in telecom power sequencing and industrial embedded controllers.
For engineers reviewing the MAX6716AUTLTD3+ datasheet, MAX6716AUTLTD3+ pinout, MAX6716AUTLTD3+ application, or MAX6716AUTLTD3+ equivalent, key selection factors include dual-supply threshold accuracy, 210ms timeout timing, push-pull reset drive capability, low 14µA supply current, and operation across –40°C to +125°C.
Technical Context
This device implements two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a digital reset timer with 210ms typical timeout, and push-pull RST output referenced to VCC1. It asserts reset when either supply falls below its threshold and holds reset for the full timeout after recovery.
It features no watchdog or manual-reset inputs (per suffix D3 and part number mapping), excludes RSTIN/PFI/WDI/MR pins in this variant, and relies solely on VCC1/VCC2 monitoring with guaranteed functionality at VCC ≥ 0.8V - enabling robust brownout detection in space-constrained, high-temperature systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed falling threshold; ensures reliable reset assertion during 5V rail brownout) |
| VCC2 Threshold | 3.075V (factory-trimmed falling threshold; matches common 3.3V I/O supply tolerance) |
| Reset Timeout | 210ms (typical minimum duration; provides sufficient hold time for processor initialization) |
| Supply Current | 14µA (typ at 3.6V; enables ultra-low-power operation in battery-backed or energy-sensitive systems) |
| Operating Temp | –40°C to +125°C (full automotive/industrial range; supports deployment in harsh environments) |
| Reset Output Type | Push-pull active-low (drives directly without external pullup; compatible with CMOS reset inputs) |
| VCC Validity Limit | 0.8V (guaranteed correct reset logic state down to this voltage; ensures fail-safe behavior during deep undervoltage) |
Pinout & Package
6-pin SOT23 package with exposed pad (RoHS-compliant, lead-free). Pinout optimized for dual-supply monitoring with minimal external components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; asserts low on VCC1/VCC2 fault and holds for 210ms timeout |
| 2 | GND | System ground reference for all internal comparators and timer circuits |
| 3 | MR | Not connected (NC) in MAX6716A variant; internal 50kΩ pullup disabled per datasheet pin mapping |
| 4 | VCC2 | Secondary supply input (monitored at 3.075V); powers internal VCC2 comparator path |
| 5 | VCC1 | Primary supply input (monitored at 4.625V); powers device core and references RST output |
| 6 | RSTIN/PFI/WDI | No-connect (NC) in MAX6716A; unused pins internally disconnected per ordering guide |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision eliminates need for two discrete supervisors |
| Factory-trimmed precision thresholds | ±1.5% threshold accuracy over temperature avoids external calibration or trimming resistors |
| Push-pull RST output | Direct-drive capability removes external pullup resistor, reducing BOM count and PCB area |
| Ultra-low quiescent current | 14µA typical supply draw extends battery life in portable equipment and backup systems |
| High-temperature operation | Guaranteed functionality up to +125°C enables use in engine control units and industrial motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716AUTLTD5+ | Same package and pinout; 420ms (typ) reset timeout instead of 210ms | Suitable for systems requiring longer reset hold time for complex boot sequences | Select when extended timeout improves reliability in multi-stage firmware initialization |
| TPS3808G33DBVR | Single-supply (3.3V only), 200ms timeout, open-drain RST, 2.5µA ICC | Lacks dual-supply monitoring; requires separate IC for 5V rail supervision | Choose only if monitoring one rail suffices and ultra-low current is prioritized over dual-rail integration |
Compared with MAX6716AUTLTD5+, the MAX6716AUTLTD3+ offers half the reset timeout for faster recovery; compared with TPS3808G33DBVR, it integrates dual-rail supervision in one 6-pin SOT23 but draws higher current - making it optimal for space-constrained dual-rail systems where 210ms timing aligns with processor boot profile.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6716AUTLTD3+?
The MAX6716AUTLTD3+ has a factory-trimmed VCC1 reset threshold of 4.625V (typical falling threshold), with ±1.5% tolerance over temperature. This value is fixed by the "T" suffix in the part number and confirmed in the Reset Voltage Threshold Suffix Guide. The MAX6716AUTLTD3+ uses this precise threshold to detect brownout on 5V rails without external resistive dividers.
Does the MAX6716AUTLTD3+ support manual reset or watchdog functionality?
No, the MAX6716AUTLTD3+ does not include manual-reset (MR), watchdog (WDI), or adjustable input (RSTIN) functionality. Per the Ordering Information table and Pin Configurations, the MAX6716A variant is configured exclusively for dual-supply monitoring with push-pull RST output. Pins 3, 6, and others associated with those features are no-connect in this specific part number.
What is the reset timeout period of the MAX6716AUTLTD3+ and how is it set?
The MAX6716AUTLTD3+ has a typical reset timeout period of 210ms, set by the "D3" suffix per the Reset Timeout Period Suffix Guide. This is a factory-programmed, temperature-compensated digital timer - not adjustable externally. The timeout begins when VCC1 or VCC2 recovers above threshold and ensures the reset signal remains asserted for the full duration regardless of transient re-falls.
Can the MAX6716AUTLTD3+ operate reliably at 0.8V supply voltage?
Yes, the MAX6716AUTLTD3+ guarantees correct reset output logic state (valid high/low assertion) when either VCC1 or VCC2 remains ≥ 0.8V - a key specification verified across –40°C to +125°C. This enables fail-safe operation during deep undervoltage conditions where other supervisors may misbehave, and is explicitly tested per Absolute Maximum Ratings and Electrical Characteristics tables.
What package type and RoHS status does the MAX6716AUTLTD3+ use?
The MAX6716AUTLTD3+ is supplied in a 6-pin SOT23 package with exposed pad, and the "+" suffix confirms it is lead-free and RoHS-compliant. This package meets JEDEC MO-178 standards, supports reflow soldering, and is rated for 696mW power dissipation at +70°C ambient - validated in the Absolute Maximum Ratings section of the datasheet.
