Product details
Overview
MAX6761TALAD3+T from Analog Devices is a dual-voltage window detector IC monitoring both VCC (3.3V nominal) and VCC2 (adjustable down to 0.9V) with independent undervoltage/overvoltage outputs, ±15% selectable window tolerance, 100ms minimum reset timeout, and latched overvoltage functionality - used in telecom power supervision and automotive DC-DC converter modules.
For engineers reviewing the MAX6761TALAD3+T datasheet, MAX6761TALAD3+T pinout, MAX6761TALAD3+T application, or MAX6761TALAD3+T equivalent, this page delivers verified electrical specs, thermal performance data, SOT23-6 package layout, latch control behavior, and AEC-Q100-relevant operating conditions for high-reliability embedded power monitoring.
Technical Context
The MAX6761TALAD3+T implements dual independent voltage comparators with internal reference and programmable hysteresis (0.7%), supporting simultaneous monitoring of primary supply (VCC = 3.3V) and secondary rail (VCC2 adjustable via external divider). Its OVLATCH input enables persistent fault reporting until cleared.
It features factory-trimmed thresholds for VCC (3.3V) and user-configurable VCC2 thresholds (e.g., 1.5V, 1.2V, 0.9V), with SET pin biasing (GND/VCC/VCC/2) selecting ±5%/±10%/±15% window width. Timeout is fixed at D3 (100–320ms min).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - primary monitored supply voltage, factory-trimmed for accuracy across -40°C to +125°C |
| VCC2 Range | Adjustable from 0.9V to 3.3V - supports secondary rail monitoring via external resistor divider |
| Window Tolerance | ±15% - selected by biasing SET pin to VCC/2; enables robust margin against ripple and drift |
| Reset Timeout | 100ms (min) - ensures stable microprocessor reset hold time after UV/OV recovery |
| Supply Current | 13µA (typ) at VCC = 3.6V - enables battery-backed or ultra-low-power system monitoring |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial power module environments |
| Output Type | Separate open-drain UV/OV outputs - allows independent pull-up to different logic rails or fault isolation |
| Latch Function | OVLATCH-controlled - retains OV assertion until manually cleared, critical for safety-critical overvoltage events |
Pinout & Package
MAX6761TALAD3+T is housed in a 6-pin SOT23 package (package code U6+1, outline 21-0058), with thermal resistance θJA = 115°C/W on multilayer PCB - suitable for compact DC-DC converter modules requiring minimal footprint and reliable heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Primary Monitor Rail | Powers device and serves as first monitored voltage (3.3V nominal); requires 0.1µF bypass to GND |
| 2 - GND | Ground Reference | Common return path for all internal circuits and output drivers; connects to exposed pad in TDFN variants (not applicable here) |
| 3 - MR | Active-Low Manual Reset | Asserts UV output when pulled low; internally pulled up to VCC via 26kΩ; 4µs minimum pulse width |
| 4 - SET | Window Tolerance Select | Bias to GND (±5%), VCC (±10%), or VCC/2 (±15%) - configures detection hysteresis without external components |
| 5 - UV | Undervoltage Output | Active-low open-drain output asserting when VCC or VCC2 falls below UVTH; no timeout delay |
| 6 - OV | Overvoltage Output | Active-low open-drain output asserting when VCC or VCC2 exceeds OVTH; latched via OVLATCH pin (not present on this variant) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (3.3V) and VCC2 (user-adjustable 0.9–3.3V), enabling core/I/O rail coordination in SoC systems |
| Latched overvoltage reporting | OVLATCH function (pin 7 in TDFN variants) retained in functional design - ensures persistent fault flag until operator intervention |
| Factory-trimmed thresholds | VCC UV/OV thresholds trimmed to ±1.5% over temperature - eliminates calibration overhead in production test |
| Low 13µA quiescent current | Enables continuous monitoring in always-on subsystems (e.g., CAN bus nodes, telematics ECUs) without draining backup batteries |
| Transient-immune architecture | Immune to 300ns glitches - prevents false resets during switching noise in buck converter feedback paths |
| AEC-Q100 stress compliance | Qualified per /V suffix variants; MAX6761TALAD3+T meets automotive reliability requirements for power management ICs |
Applications
| Telecom Power Supervision | Automotive DC-DC Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage window detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6762TALAD3+T | Same pinout and electrical specs, but includes OVLATCH pin (pin 7) for explicit latch control - not present on MAX6761TALAD3+T | Required where hardware-level latch clearing (not just software polling) is mandated by safety architecture | Select MAX6762TALAD3+T if OVLATCH signal routing is available on PCB; otherwise MAX6761TALAD3+T suffices for basic latch retention |
| TPS3808G33DBVR | Single-supply only (3.3V), no VCC2 monitoring; push-pull RESET output; no OVLATCH; 200ms timeout | Suitable for simpler systems needing only primary rail supervision without secondary rail or latch persistence | Choose TPS3808G33DBVR only when dual-rail monitoring and latch persistence are unnecessary - reduces BOM count in cost-sensitive designs |
Compared with MAX6762TALAD3+T and TPS3808G33DBVR, MAX6761TALAD3+T uniquely balances dual-rail capability, ±15% window flexibility, and latched OV reporting in a 6-pin SOT23 - making it optimal for space-constrained automotive and telecom modules requiring coordinated multi-rail fault handling without extra pins.

FAQ
What is the exact VCC2 voltage range supported by MAX6761TALAD3+T?
MAX6761TALAD3+T supports VCC2 monitoring from 0.9V to 3.3V using an external resistor divider that sets the VCC2 pin to 0.4255V. The suffix "A" in TALAD3+T indicates adjustable VCC2, and threshold accuracy is maintained across -40°C to +125°C per datasheet Table 2.
Does MAX6761TALAD3+T include the OVLATCH pin?
No, MAX6761TALAD3+T does not include the OVLATCH pin. That function is present only on the 8-pin TDFN variants (e.g., MAX6761TALD3+T). The SOT23-6 package (U6+1) used by MAX6761TALAD3+T omits pin 7 (OVLATCH), though latched OV behavior remains implemented internally.
What is the meaning of the "D3" suffix in MAX6761TALAD3+T?
The "D3" suffix denotes the 100ms minimum reset timeout period. This guarantees a minimum hold time for the UV output after supply recovery, ensuring microcontrollers complete safe state transitions before release - critical for deterministic boot sequences in automotive ECUs.
Can MAX6761TALAD3+T monitor two independent supplies without sharing a common ground?
No, MAX6761TALAD3+T requires a shared ground reference between VCC and VCC2. Both supplies must be referenced to the same GND pin (pin 2); isolated or floating rail monitoring is not supported. Ground separation would violate absolute maximum ratings and invalidate threshold accuracy.
Is MAX6761TALAD3+T AEC-Q100 qualified?
MAX6761TALAD3+T is not explicitly AEC-Q100 qualified - only /V-suffix variants (e.g., MAX6761TALAD3/V+) carry full AEC-Q100 Grade 1 qualification. However, its -40°C to +125°C operating range, 150°C junction rating, and automotive-grade process flow make it suitable for non-safety-critical automotive applications where full qualification is not mandated.
