Product details
Overview
MAX6715AUTYDD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in SOT23-5 package, monitoring VCC1 (4.50V–4.75V factory-trimmed threshold) and VCC2 (0.765V–0.810V threshold), with 140ms minimum 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 controller brownout protection.
For engineers reviewing the MAX6715AUTYDD3+T datasheet, MAX6715AUTYDD3+T pinout, MAX6715AUTYDD3+T application, or MAX6715AUTYDD3+T equivalent, key selection factors include dual-rail voltage monitoring tolerance, 140ms reset hold time, low 15µA supply current at 3.6V, immunity to sub-20µs VCC transients, and SOT23-5 footprint compatibility with space-constrained embedded systems.
Technical Context
The MAX6715AUTYDD3+T integrates two independent voltage comparators with hysteresis (0.5% of threshold), a precision 1.22V internal reference scaled for VCC1/VCC2 thresholds, and a digital reset timeout timer with fixed 140ms (D3 suffix) delay. It asserts RST when either supply falls below its trimmed threshold and holds reset for the full timeout after recovery.
No watchdog, manual-reset, or power-fail inputs are enabled on this variant (suffix TYDD3 indicates VCC1/VCC2 monitoring only, push-pull RST, 140ms timeout, no WDI/MR/PFI). The device operates across -40°C to +125°C and guarantees valid logic states with VCC ≥ 0.8V - critical for automotive and industrial hot-swap applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.500V–4.750V (factory-trimmed, ±1.25% typical; ensures reliable reset assertion during 5V rail brownout) |
| VCC2 Threshold | 0.765V–0.810V (factory-trimmed, supports 0.9V core supply monitoring with margin) |
| Reset Timeout | 140ms min (D3 suffix; provides sufficient hold time for FPGA/CPU initialization sequences) |
| Supply Current | 15µA typ at 3.6V (enables always-on supervision in battery-backed systems without significant drain) |
| Operating Temp | -40°C to +125°C (AEC-Q100-qualified grade; validated for under-hood and industrial control environments) |
| Reset Valid Down To | VCC1 or VCC2 = 0.8V (guaranteed functional reset assertion even during deep undervoltage conditions) |
| VCC Transient Immunity | Immune to <20µs negative glitches (prevents spurious resets during switching noise or load dump) |
Pinout & Package
Package: 5-pin SOT23 (U5+1 code), 2.9mm × 1.6mm × 1.1mm body, JEDEC MO-178AC compliant, thermal resistance θJA = 324.3°C/W (four-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low push-pull reset output | Drives low to reset μP; referenced to VCC1; sinks 1.2mA at 2.7V; requires no external pullup |
| 2 - GND | Ground reference | Common return for all internal comparators, timer, and output driver; must be low-impedance |
| 3 - MR | Active-low manual-reset input | Internally pulled up to VCC1 (50kΩ); pulling low forces immediate reset; unused pin may float |
| 4 - VCC2 | Secondary supply input | Powers internal VCC2 comparator chain; monitors 0.765V–0.810V rail; must be ≥0.8V for valid operation |
| 5 - VCC1 | Primary supply input | Powers entire IC and primary comparator; monitors 4.50V–4.75V rail; supplies RST output stage |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of primary (5V) and secondary (0.9V) rails with separate thresholds and hysteresis |
| Guaranteed reset validity at 0.8V | Ensures deterministic reset behavior during deep brownout - critical for fail-safe system shutdown |
| Low quiescent current (15µA) | Enables permanent supervision in energy-sensitive applications without compromising battery life |
| Push-pull RST output | Eliminates need for external pullup resistor; drives high/low actively; compatible with bidirectional μP reset pins via 4.7kΩ series resistor |
| High noise immunity | 20µs glitch rejection and built-in hysteresis prevent false resets in electrically noisy industrial environments |
Applications
| Telecom Power Sequencing | Industrial PLC Controller |
|---|---|
Use Scenario: Dual-rail power-up sequencing in 48V DC-fed telecom line cards with 5V management and 0.9V FPGA core supplies. IC Role / Device Role / Timing Role: Supervises VCC1 (5V) and VCC2 (0.9V) independently; asserts RST until both rails stabilize above thresholds and hold for 140ms. Use Value: Prevents FPGA configuration corruption by ensuring both rails meet timing margins before release from reset. |
Use Scenario: Brownout detection in DIN-rail mounted programmable logic controllers operating in factory-floor environments with unstable 24VDC input. IC Role / Device Role / Timing Role: Monitors auxiliary 5V logic rail and 0.9V microcontroller core rail; triggers hard reset on simultaneous undervoltage. Use Value: Guarantees deterministic restart during voltage sags - avoids undefined state in safety-critical control loops. |
| Automotive Infotainment Module | Medical Diagnostic Equipment |
Use Scenario: Cold-cranking support in head-unit modules where battery voltage dips to 6V while 5V LDO and 0.9V SoC rails remain active. IC Role / Device Role / Timing Role: Validates VCC1 (5V) and VCC2 (0.9V) integrity down to 0.8V; maintains RST assertion until both recover and timeout completes. Use Value: Meets AEC-Q100 Grade 1 requirements for continuous operation during engine start transients. |
Use Scenario: Power supervision in portable ultrasound devices using Li-ion battery (3.0–4.2V) stepped down to 5V and 0.9V rails. IC Role / Device Role / Timing Role: Detects simultaneous collapse of both regulated rails during battery depletion; initiates controlled shutdown sequence. Use Value: Enables safe data save and hardware disable before complete power loss - critical for regulatory compliance (IEC 62304). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716AUTYDD3+T | Same package and timing, but open-drain RST output (requires external pullup) | Suitable where μP reset pin is bidirectional and external pullup already exists | Select when board layout includes 4.7kΩ pullup to VCC1 and system requires lower leakage during reset assertion |
| TPS3808G33DBVR | Single-supply (3.3V only), 200ms timeout, 2.5µA IQ, SOT23-5 | Lacks VCC2 monitoring; not suitable for dual-rail systems requiring independent 0.9V supervision | Choose only for cost-sensitive single-rail designs where 0.9V core rail supervision is handled elsewhere |
Compared with MAX6715AUTYDD3+T, MAX6716AUTYDD3+T offers identical timing and thresholds but requires external pullup for RST, increasing BOM count; TPS3808G33DBVR reduces supply current but eliminates dual-voltage capability - making it unsuitable for applications requiring concurrent 5V/0.9V fault detection.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6715AUTYDD3+T?
The MAX6715AUTYDD3+T has a factory-trimmed VCC1 reset threshold of 4.500V (min), 4.625V (typ), and 4.750V (max) - corresponding to the 'L' suffix in the Reset Voltage Threshold Suffix Guide. This ensures precise 5V rail supervision with ±1.25% tolerance over temperature and process variation.
Does MAX6715AUTYDD3+T support monitoring a third voltage rail?
No, MAX6715AUTYDD3+T does not support triple-voltage monitoring. Its suffix 'TYDD3' indicates dual-supply supervision only (VCC1 and VCC2). For RSTIN-based auxiliary monitoring, select variants like MAX6719AUTYDD3+T - the MAX6715AUTYDD3+T lacks the RSTIN input pin and associated comparator circuitry.
What is the function of Pin 3 (MR) on MAX6715AUTYDD3+T?
Pin 3 is the active-low Manual-Reset (MR) input on MAX6715AUTYDD3+T. It features an internal 50kΩ pullup to VCC1. Pulling MR low forces an immediate reset assertion, held for the full 140ms timeout after MR returns high. If unused, MR may be left floating or tied to VCC1.
Is MAX6715AUTYDD3+T qualified for automotive applications?
Yes, MAX6715AUTYDD3+T is AEC-Q100 qualified (Grade 1: -40°C to +125°C ambient). Its guaranteed operation down to VCC = 0.8V, 140ms reset timeout, and robust transient immunity make it suitable for automotive infotainment, body control, and ADAS subsystems requiring fail-safe power supervision.
What package type and footprint does MAX6715AUTYDD3+T use?
MAX6715AUTYDD3+T uses a 5-pin SOT23 package (package code U5+1, outline 21-0057). Its footprint matches JEDEC MO-178AC standard: 2.9mm × 1.6mm body, 0.95mm pitch, and 1.1mm max height - compatible with automated SMT assembly and reflow profiles for lead-free soldering.
