Product details
Overview
MAX6716AUTSVD3+ 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 reset timeout, push-pull active-low RST output, and guaranteed reset validity down to VCC = 0.8V. It supports telecom power sequencing, industrial CPU reset assertion, and battery-backed system supervision.
For engineers reviewing the MAX6716AUTSVD3+ datasheet, MAX6716AUTSVD3+ pinout, MAX6716AUTSVD3+ application, or MAX6716AUTSVD3+ equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over -40°C to +125°C), ultra-low 14µA supply current at 3.6V, immunity to sub-20µs VCC transients, and compatibility with manual-reset and watchdog timer integration.
Technical Context
The MAX6716AUTSVD3+ integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a precision 210ms reset timeout timer, and push-pull RST output referenced to VCC1. Its internal logic asserts reset when either supply falls below its threshold and holds reset for the full timeout after recovery.
It features guaranteed operation with VCC1 or VCC2 ≥ 0.8V, 20ppm/°C reset threshold tempco, and 0.5% hysteresis referenced to typical VTH. The device lacks RSTIN, WDI, PFI, and PFO pins-confirmed by its 6-pin SOT23 pinout and suffix "D3" indicating dual-supply-only, no adjustable input or watchdog.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed, ±1.5% over temp; ensures reliable reset during 5V rail brownout) |
| VCC2 Threshold | 3.075V (factory-trimmed, ±1.5% over temp; matches common 3.3V I/O supply tolerance) |
| Reset Timeout | 210ms (minimum; provides sufficient hold time for ARM Cortex-M boot sequence) |
| Supply Current | 14µA typical at 3.6V (enables >10-year battery life in always-on supervisory applications) |
| Operating Temp | -40°C to +125°C (supports under-hood automotive and industrial control environments) |
| Reset Output Type | Push-pull active-low (drives directly into µP reset pin without external pullup; VOH ≥ 0.8×VCC1) |
| VCC Validity Limit | 0.8V minimum (guarantees correct reset state during deep brownout, enabling fail-safe shutdown) |
Pinout & Package
MAX6716AUTSVD3+ uses a 6-pin SOT23 package (JEDEC MO-178AA), 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and RoHS-compliant matte-tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; sinks up to 3.2mA at VCC1 ≥ 4.5V; asserts when VCC1 < 4.625V or VCC2 < 3.075V |
| 2 | GND | Ground reference for all internal comparators, timer, and output stage |
| 3 | MR | Active-low manual-reset input; internal 50kΩ pullup to VCC1; 1µs minimum pulse width required |
| 4 | VCC2 | Secondary supply input (3.075V monitor); powers internal circuitry when VCC2 > VCC1 |
| 5 | VCC1 | Primary supply input (4.625V monitor); powers internal circuitry when VCC1 > VCC2; defines RST VOH level |
| 6 | NC | No connect; internally unconnected; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | 4.625V (VCC1) and 3.075V (VCC2) with ±1.5% accuracy over full temperature range |
| Guaranteed reset validity at low VCC | Operates correctly with VCC1 or VCC2 ≥ 0.8V-critical for controlled power-down sequences |
| Ultra-low quiescent current | 14µA typical at 3.6V enables use in energy-harvesting and long-life battery systems |
| Push-pull RST output | Eliminates need for external pullup resistor; drives µP reset pin directly with 0.4V VOL at 3.2mA sink |
| Immunity to short VCC transients | Rejects negative-going glitches <20µs duration (at 100mV overdrive), preventing spurious resets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | 3.3V fixed VDD threshold only; single-supply monitor; 200ms timeout; 1.6µA IQ | Lacks VCC2 monitoring capability; requires external resistor divider for dual-rail use | Select when only one supply needs supervision and ultra-low IQ is critical |
| ADM6716AKSZ-REEL7 | 4.63V/3.08V thresholds; 200ms timeout; open-drain RST; 18µA IQ; same SOT23-6 package | Requires external pullup; higher leakage on RST during reset; slightly looser threshold tolerance (±2.5%) | Select when board already uses open-drain reset topology or ADM portfolio consolidation is preferred |
Compared with TPS3808G33DBVR and ADM6716AKSZ-REEL7, MAX6716AUTSVD3+ delivers true dual-supply monitoring with push-pull RST, tighter threshold accuracy (±1.5%), and guaranteed 0.8V operation-making it optimal for high-reliability embedded systems where both rails must be independently validated before release.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6716AUTSVD3+?
The MAX6716AUTSVD3+ has factory-trimmed reset thresholds of 4.625V for VCC1 and 3.075V for VCC2, with ±1.5% accuracy over the full -40°C to +125°C operating range. These values are defined by the "TS" and "VD" suffixes in the part number and confirmed in the Reset Voltage Threshold Suffix Guide. The MAX6716AUTSVD3+ does not support adjustable thresholds or third-supply monitoring.
Does the MAX6716AUTSVD3+ include a watchdog timer or power-fail input?
No, the MAX6716AUTSVD3+ does not include a watchdog timer (WDI), power-fail input (PFI), or power-fail output (PFO). Its 6-pin SOT23 configuration and "D3" timeout suffix confirm it is a dual-supply-only variant with RST, GND, MR, VCC2, VCC1, and NC pins. Watchdog and PFI/PFO functionality requires variants like MAX6729A or MAX6797A.
What is the reset timeout period of the MAX6716AUTSVD3+ and how is it guaranteed?
The MAX6716AUTSVD3+ provides a minimum reset timeout period of 210ms, as indicated by the "D3" suffix in its part number. This value is production-tested and guaranteed over temperature and voltage. The timeout begins when VCC1 and VCC2 rise above their respective thresholds and ends with RST deassertion-ensuring sufficient hold time for complex processor initialization sequences.
Can the MAX6716AUTSVD3+ operate reliably during deep brownout conditions?
Yes, the MAX6716AUTSVD3+ guarantees valid reset output logic state with VCC1 or VCC2 ≥ 0.8V-verified across -40°C to +125°C. This allows deterministic reset assertion during severe brownout events before supply collapse, unlike many supervisors that fail below 1.0V. No external components are needed to maintain this behavior.
Is the RST output of the MAX6716AUTSVD3+ push-pull or open-drain?
The MAX6716AUTSVD3+ features a push-pull active-low RST output, as confirmed by its "T" suffix (per Selector Guide) and electrical specs showing VOH ≥ 0.8×VCC1 and VOL ≤ 0.4V at 3.2mA sink. This eliminates the need for an external pullup resistor and enables direct connection to most microprocessor reset inputs.
