Product details
Overview
MAX6719AUTTZD6+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory IC monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V), with externally adjustable RSTIN threshold (626mV internal reference), 560ms min reset timeout, and push-pull active-low RST output. It guarantees valid reset assertion down to VCC1 or VCC2 = 0.8V and operates across –40°C to +125°C for industrial power-rail monitoring in multivoltage systems.
For engineers reviewing the MAX6719AUTTZD6+T datasheet, MAX6719AUTTZD6+T pinout, MAX6719AUTTZD6+T application, or MAX6719AUTTZD6+T equivalent, key selection criteria include its factory-trimmed dual-threshold architecture, 14µA typical supply current at 3.6V, immunity to sub-20µs VCC transients, and SOT23-6 package compatibility with space-constrained embedded designs requiring triple-voltage supervision with watchdog disable capability.
Technical Context
The MAX6719AUTTZD6+T integrates two independent voltage comparators (VCC1 and VCC2) with factory-trimmed thresholds, an adjustable RSTIN comparator referenced to a 626mV internal bandgap, and a reset timeout timer with fixed 560ms minimum period (suffix D6). Its push-pull RST output is referenced to VCC1 and asserts low when any monitored supply falls below its threshold or MR is pulled low.
It features no watchdog or power-fail circuitry - confirmed by pin mapping (no WDI, PFI, or PFO pins assigned) and ordering suffix decoding (T = RSTIN option, Z = push-pull RST, D6 = 560ms timeout). The device uses internal 50kΩ MR pullup and guarantees reset validity down to 0.8V on either supply rail, enabling reliable brownout detection in battery-backed and automotive-grade applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VCC1: 0.8V–5.5V; VCC2: 0.8V–5.5V - supports operation during deep brownout and enables supervision of core & I/O rails simultaneously |
| Reset Timeout Period | 560ms (min) - ensures sufficient hold time for full μP initialization before release, per suffix D6 |
| VCC1 Reset Threshold | 2.850V (typ, suffix S) - factory-trimmed for 2.85V primary supply monitoring with ±0.075V tolerance |
| VCC2 Reset Threshold | 2.850V (typ, suffix S) - matched dual-threshold configuration for symmetric dual-rail systems |
| RSTIN Threshold Voltage | 626.5mV (typ) - internal reference enabling external resistor-divider setup for third-voltage monitoring down to 0.62V |
| Supply Current | 14µA (typ at 3.6V) - ultra-low quiescent draw critical for always-on battery-powered subsystems |
| Operating Temperature | –40°C to +125°C - AEC-Q100 qualified variant available; this part meets full industrial temperature range requirements |
Pinout & Package
MAX6719AUTTZD6+T is housed in a 6-pin SOT23 package (package code U6+1), with 1.6mm × 2.9mm footprint and 0.95mm height. Pin 1 is marked via dot; pin numbering follows standard SOT23 counterclockwise convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low push-pull reset output referenced to VCC1; asserts low on VCC1/VCC2/RSTIN fault or MR low; remains low for full 560ms timeout |
| 2 | GND | Analog/digital ground reference for all comparators, timers, and output drivers; must be low-impedance connection |
| 3 | MR | Active-low manual-reset input with internal 50kΩ pullup to VCC1; 1µs minimum pulse width required to trigger reset |
| 4 | VCC2 | Secondary supply input powering VCC2 comparator and RST2 logic (not present on this variant); also used as reference for VCC2 threshold detection |
| 5 | VCC1 | Primary supply input powering core logic, RST driver, and VCC1 comparator; defines VOH level for push-pull RST output |
| 6 | RSTIN | High-impedance adjustable reset input; monitors external voltage via resistor divider; asserts reset when voltage falls below 626.5mV reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage supervision | Simultaneous monitoring of VCC1 (1.8–5.0V) and VCC2 (0.9–3.3V) with factory-trimmed thresholds eliminates need for discrete comparators and reduces BOM count |
| Externally adjustable third-voltage monitor | RSTIN pin with 626.5mV internal reference enables precise supervision of auxiliary rails (e.g., 1.2V DDR, 0.9V FPGA core) using only two external resistors |
| Guaranteed reset validity down to 0.8V | Ensures deterministic reset assertion even during severe brownout conditions where VCC drops near silicon cutoff - critical for fail-safe embedded control |
| Ultra-low supply current | 14µA typical at 3.6V allows integration into energy-sensitive applications such as IoT sensor nodes and backup power domains without impacting battery life |
| SOT23-6 industrial package | 6-pin SOT23 footprint provides PCB area savings over SOIC-8 while maintaining thermal performance (θJA = 115°C/W on multilayer board) |
Applications
| Industrial PLC Power Management | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6720AUTTZD6+T | Identical pinout and electrical specs, but VCC1/VCC2 thresholds factory-trimmed to 3.075V (suffix T) instead of 2.850V (suffix S) | Targeted at 3.0V/3.3V system rails rather than 2.85V/2.85V matched dual-rail configurations | Select MAX6720AUTTZD6+T when primary/secondary supplies require higher trip points; otherwise MAX6719AUTTZD6+T provides tighter margin for 2.85V rails. |
| TLV809E33DBZR | Single-supply 3.3V reset IC (SOT23-3), no VCC2 or RSTIN inputs, 200ms timeout, 1.6µA ICC | Lacks dual-rail monitoring and adjustable third-input capability; suitable only for basic single-rail reset | Use TLV809E33DBZR only if system requires minimal footprint and single-rail supervision; MAX6719AUTTZD6+T is mandatory for true dual/three-rail integrity. |
Compared with MAX6720AUTTZD6+T, MAX6719AUTTZD6+T offers lower VCC1/VCC2 thresholds ideal for 2.85V systems, while TLV809E33DBZR sacrifices supervision flexibility for ultra-low current - making MAX6719AUTTZD6+T the sole choice for space-constrained dual-rail designs needing RSTIN configurability.

FAQ
What is the reset timeout period for MAX6719AUTTZD6+T?
The MAX6719AUTTZD6+T has a guaranteed minimum reset timeout period of 560ms, as indicated by the "D6" suffix in its part number. This fixed timeout ensures the reset signal remains asserted long enough for complete microprocessor initialization after power-up or brownout recovery, and is not user-adjustable. The timeout begins when any monitored supply (VCC1, VCC2, or RSTIN) falls below its threshold and ends only after all supplies exceed their thresholds and the full 560ms elapses.
Does MAX6719AUTTZD6+T include a watchdog timer?
No, MAX6719AUTTZD6+T does not include a watchdog timer. Its ordering suffix "T" denotes the RSTIN adjustable input option, and "Z" specifies push-pull RST output - neither implies watchdog functionality. Watchdog capability is only present in variants with "W" or "WD" suffixes (e.g., MAX6721A). The MAX6719AUTTZD6+T relies solely on voltage monitoring and manual reset for system supervision.
What are the factory-trimmed reset thresholds for VCC1 and VCC2 on MAX6719AUTTZD6+T?
MAX6719AUTTZD6+T uses the "S" threshold suffix, specifying a typical VCC1 reset threshold of 2.850V (range: 2.850V–3.000V) and a typical VCC2 reset threshold of 2.850V (range: 2.850V–3.000V). These values are laser-trimmed at wafer test and guaranteed over temperature (–40°C to +125°C) with ±0.075V tolerance. The matching thresholds simplify design for symmetric dual-rail systems like 2.85V FPGA banks.
Can MAX6719AUTTZD6+T monitor a third voltage, and how is it configured?
Yes, MAX6719AUTTZD6+T can monitor a third voltage via the RSTIN pin, which references an internal 626.5mV bandgap. To configure, connect an external resistor divider from the target supply (e.g., 1.2V rail) to GND, with the midpoint feeding RSTIN. The trip point is calculated as VTRIP = 626.5mV × (R1 + R2)/R2. This enables precise supervision of auxiliary rails without additional ICs, and RSTIN's 100nA max input current minimizes divider power loss.
What is the supply current consumption of MAX6719AUTTZD6+T at 3.6V?
MAX6719AUTTZD6+T draws 14µA typical supply current at 3.6V with all outputs unasserted and I/O connections open, as specified in the Electrical Characteristics table. This ultra-low quiescent current is critical for battery-backed applications and always-on subsystems. Total current scales with temperature and supply voltage, remaining below 39µA maximum across the full operating range, enabling multi-year operation in energy-constrained designs.
