Product details
Overview
The MAX6715AUTTGD3+ from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit monitoring VCC1 (primary) and VCC2 (secondary) with factory-trimmed reset thresholds, 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 embedded controllers.
For engineers reviewing the MAX6715AUTTGD3+ datasheet, MAX6715AUTTGD3+ pinout, MAX6715AUTTGD3+ application, or MAX6715AUTTGD3+ equivalent, key selection criteria include dual-voltage monitoring range (1.8V–5.0V / 0.9V–3.3V), 140ms reset timeout (D3 suffix), SOT23-6 package, -40°C to +125°C operation, and integrated manual-reset input with 50kΩ internal pullup.
Technical Context
This device implements independent voltage comparators for VCC1 and VCC2 with 0.5% hysteresis and 20ppm/°C tempco, asserting reset when either supply falls below its threshold. It guarantees correct reset logic state with VCC1 or VCC2 ≥ 0.8V and supports external RSTIN monitoring only in select variants (not MAX6715A).
The MAX6715AUTTGD3+ features a fixed 140ms reset timeout (D3 suffix), push-pull RST output referenced to VCC1, active-low manual-reset input (MR) with 1µs minimum pulse width and 100ns glitch rejection, and no watchdog or power-fail functionality - distinguishing it from MAX6721A–MAX6729A/MAX6797A variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VCC1 = 0.8V to 5.5V; VCC2 = 0.8V to 5.5V - enables operation across brownout and low-power states without loss of reset integrity. |
| Reset Timeout Period | 140ms (min) - ensures sufficient hold time for processor initialization and peripheral stabilization after power recovery. |
| VCC1 Reset Threshold | 4.625V (typ), ±125mV tolerance - factory-trimmed for precise 4.63V nominal trip point (suffix 'G') on primary supply. |
| VCC2 Reset Threshold | 3.075V (typ), ±75mV tolerance - factory-trimmed for precise 3.08V nominal trip point (suffix 'D') on secondary supply. |
| Supply Current | 15µA (typ) at VCC1 < 5.5V - ultra-low quiescent current preserves battery life in portable equipment. |
| 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 resistor and provides rail-to-rail drive capability. |
Pinout & Package
SOT23-6 package (package code U6+1), 1.6mm × 2.9mm footprint, 0.95mm height, thermal resistance θJA = 115°C/W (multilayer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; asserts low during fault and holds for 140ms after recovery. |
| 2 | GND | Ground reference for all internal comparators and output drivers; must be low-impedance connection. |
| 3 | MR | Active-low manual-reset input with 50kΩ internal pullup to VCC1; 1µs minimum pulse width required for reliable assertion. |
| 4 | VCC2 | Secondary supply input powering comparator for VCC2 monitoring; also serves as reference for RST2 in other variants (not present in MAX6715A). |
| 5 | VCC1 | Primary supply input powering core logic and VCC1 comparator; defines reset output voltage levels and MR pullup source. |
| 6 | RST2 | Not connected (NC) in MAX6715A - reserved for dual-output variants; unused pin with no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of VCC1 (1.8–5.0V) and VCC2 (0.9–3.3V) with separate thresholds ensures robust multirail system reliability. |
| Guaranteed reset validity at low VCC | Outputs remain logically valid even when VCC1 or VCC2 drops to 0.8V - critical for graceful shutdown in brownout conditions. |
| Immunity to short VCC transients | Rejects glitches ≤20µs duration (at 100mV overdrive), preventing spurious resets during switching noise or load transients. |
| Low supply current | 15µA typical ICC1 enables >10-year battery life in always-on monitoring applications such as remote sensors. |
| Industrial temperature grade | -40°C to +125°C operation supports deployment in harsh environments including motor drives and base station power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716AUTTGD3+ | Identical pinout and electrical specs, but open-drain RST output requiring external pullup resistor. | Suitable where level-shifting or wired-OR reset bus is needed; incompatible with direct MCU reset pin drive without pullup. | Select MAX6716AUTTGD3+ only if system requires open-drain reset for bus sharing or voltage translation. |
| TPS3808G33DBVR | Single-supply (VDD only), 3.3V fixed threshold, 200ms timeout, SOT23-6 - lacks VCC2 monitoring and manual reset input. | Applicable only for single-rail systems; cannot replace dual-monitoring function without redesigning power architecture. | Choose TPS3808G33DBVR only when supervising one supply and cost sensitivity outweighs feature parity. |
Compared with MAX6716AUTTGD3+, the MAX6715AUTTGD3+ eliminates external pullup components and simplifies layout; versus TPS3808G33DBVR, it delivers essential dual-rail monitoring and MR support required for complex embedded systems.

FAQ
What is the reset timeout period for MAX6715AUTTGD3+?
The MAX6715AUTTGD3+ has a fixed minimum reset timeout period of 140ms (D3 suffix), guaranteed over -40°C to +125°C. This interval begins when VCC1 and VCC2 rise above their respective thresholds and ensures sufficient hold time for microprocessor initialization before release. The timeout is internally generated and not adjustable.
Does MAX6715AUTTGD3+ support watchdog timer functionality?
No, MAX6715AUTTGD3+ does not include watchdog timer functionality. Watchdog inputs (WDI) and associated timing circuits are present only in MAX6721A–MAX6729A/MAX6797A variants. The MAX6715AUTTGD3+ is a dedicated dual-supply voltage supervisor with manual-reset input and fixed 140ms reset timeout.
What are the factory-trimmed reset thresholds for MAX6715AUTTGD3+?
The MAX6715AUTTGD3+ uses suffix 'G' for VCC1 (4.625V typical, 4.500V–4.750V min/max) and 'D' for VCC2 (3.075V typical, 3.000V–3.150V min/max). These thresholds are laser-trimmed at wafer test and specified over full temperature range with 20ppm/°C tempco and 0.5% hysteresis.
Can MAX6715AUTTGD3+ monitor a third voltage using RSTIN?
No, MAX6715AUTTGD3+ does not support RSTIN functionality. Adjustable third-voltage monitoring via RSTIN is available only in MAX6719A/MAX6720A and MAX6723A–MAX6727A variants. The MAX6715AUTTGD3+ is strictly a dual-supply supervisor with no RSTIN pin connection or internal circuitry.
What is the package type and pin compatibility of MAX6715AUTTGD3+?
MAX6715AUTTGD3+ is supplied in a 6-pin SOT23 package (U6+1 code) with 1.6mm × 2.9mm footprint. It shares identical pinout with MAX6716A–MAX6722A variants, differing only in reset output type (push-pull vs. open-drain) and internal feature set - enabling drop-in replacement where output drive requirements match.
