Product details
Overview
MAX6762TATWD3+ from Maxim Integrated is a dual-voltage window detector IC designed to monitor undervoltage and overvoltage conditions on two independent power rails-VCC (3.3V nominal) and VCC2 (1.8V nominal)-with ±10% factory-trimmed thresholds, 100ms minimum reset timeout, latched overvoltage output, manual reset input, and operation from -40°C to +125°C. It serves as a system-level power supervisor in microprocessor-based industrial controllers.
For engineers reviewing the MAX6762TATWD3+ datasheet, MAX6762TATWD3+ pinout, MAX6762TATWD3+ application, or MAX6762TATWD3+ equivalent, key selection considerations include dual-rail monitoring capability, latched OV response for fault persistence, ±10% window tolerance, TDFN-8 package footprint, and compatibility with 1.8V/3.3V I/O domains in automotive and industrial embedded systems.
Technical Context
The MAX6762TATWD3+ integrates two independent voltage comparators-one for VCC (3.3V) and one for VCC2 (1.8V)-each with programmable ±10% window via SET pin tied to VCC. It features separate UV and OV open-drain outputs, a latched OV function controlled by OVLATCH, and a manual reset input with internal 26kΩ pull-up.
Its timing architecture includes a 100ms minimum reset timeout period (D3 suffix), 20µs propagation delay for UV/OV assertion, and guaranteed output validity down to VCC = 1.0V. The device draws only 13–30µA supply current and operates across the full -40°C to +125°C extended temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 3.3V nominal, ±10% window (OVTH = 3.63V / UVTH = 2.97V at TA = +25°C) |
| VCC2 Threshold | 1.8V nominal, ±10% window (OVTH2 = 1.98V / UVTH2 = 1.62V at TA = +25°C) |
| Reset Timeout | 100ms minimum (D3 option); ensures stable MCU boot after brownout recovery |
| Supply Current | 13–30µA at VCC = 3.6V; enables ultra-low-power always-on supervision |
| Operating Temp | -40°C to +125°C; qualified for under-hood automotive and industrial control environments |
| Output Type | Open-drain UV and OV outputs; supports wired-OR logic and flexible pull-up voltage selection |
| Manual Reset | Active-low MR with 4µs min pulse width and 26kΩ internal pull-up; simplifies external reset button design |
Pinout & Package
MAX6762TATWD3+ is housed in an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP) internally connected to GND. Pin 1 is marked with dot; EP must be soldered to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Main power supply input and first monitored rail (3.3V nominal) |
| 2 | GND | Analog/digital ground reference; connects to EP for low-impedance return path |
| 3 | OVLATCH | High-impedance latch control: high = latch OV, low = clear latch, GND = transparent mode |
| 4 | VCC2 | Second monitored rail input (1.8V nominal); powers internal comparator for dual-supply monitoring |
| 5 | UV | Active-low open-drain undervoltage output; asserts when VCC or VCC2 falls below UVTH |
| 6 | OV | Active-low open-drain overvoltage output; latched when OVLATCH = high; no timeout |
| 7 | MR | Active-low manual reset input; internally pulled up to VCC (26kΩ); initiates UV/OV assertion |
| 8 | SET | Window select input: tied to VCC for ±10% threshold tolerance (per TATW suffix) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V core and 1.8V I/O rails without external resistors or dividers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage window detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TATWD3+ | Identical pinout, same VCC/VCC2 thresholds and timing; differs only in UV output type (push-pull vs. open-drain) | Requires level-shifting if interfacing with 1.8V logic; lacks wired-OR capability of open-drain UV | Select when push-pull drive strength needed for long trace routing or capacitive loads |
| TPS3808G33DBVR | Single-rail (3.3V only), no VCC2 input or latched OV; 2% threshold accuracy vs. ±10%; SOT-23-6 package | Cannot supervise dual supplies; requires external circuitry for latch functionality and 1.8V rail monitoring | Choose for cost-sensitive single-rail designs where ±2% accuracy and smaller footprint outweigh dual-rail need |
Compared with MAX6761TATWD3+, the MAX6762TATWD3+ provides open-drain UV for flexible voltage-domain interfacing; versus TPS3808G33DBVR, it delivers true dual-rail supervision with latch and wider temperature range-enabling consolidated power monitoring in complex embedded systems.

FAQ
What voltage rails does the MAX6762TATWD3+ monitor?
The MAX6762TATWD3+ monitors two independent voltage rails: VCC at 3.3V nominal and VCC2 at 1.8V nominal, both with ±10% factory-trimmed window thresholds. It asserts UV or OV outputs when either rail falls below its undervoltage threshold or rises above its overvoltage threshold. This dual-monitoring capability eliminates the need for separate supervisors on core and I/O supplies.
How does the latched overvoltage function work on the MAX6762TATWD3+?
The MAX6762TATWD3+ implements latched overvoltage behavior via the OVLATCH pin: when OVLATCH is driven high, the OV output remains asserted even after the overvoltage condition clears, until OVLATCH is actively pulled low. When OVLATCH is grounded, the OV output operates transparently-deasserting immediately upon return to valid voltage. This feature enables persistent fault signaling for diagnostic logging in safety-critical systems.
What is the purpose of the SET pin on the MAX6762TATWD3+?
On the MAX6762TATWD3+, the SET pin selects the window tolerance: tied to VCC (as indicated by the 'T' in TATW), it configures ±10% undervoltage and overvoltage thresholds around the nominal 3.3V and 1.8V rails. This eliminates external resistor networks and guarantees threshold accuracy across temperature, simplifying design for applications requiring known voltage margins like industrial control and automotive subsystems.
Does the MAX6762TATWD3+ support operation at low supply voltages?
Yes, the MAX6762TATWD3+ guarantees correct UV/OV output logic states for VCC down to 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V. Its 13–30µA supply current and operation from -40°C to +125°C make it suitable for battery-backed systems and extended-temperature industrial environments where reliable low-voltage supervision is essential.
What package type is used for the MAX6762TATWD3+?
The MAX6762TATWD3+ uses an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP) internally connected to GND. This compact, thermally enhanced package supports high-density PCB layouts and requires EP soldering to the PCB ground plane for optimal thermal dissipation and noise immunity in noisy industrial or automotive settings.
