Product details
Overview
MAX6762TAWED3+ from Analog Devices is a dual-voltage window detector IC monitoring both VCC and VCC2 supplies, with factory-trimmed 3.3V/1.8V thresholds, ±15% window select (SET = VCC/2), 100ms minimum reset timeout (D3 suffix), latched overvoltage output, and manual reset input. It operates from -40°C to +125°C in automotive and industrial power-rail supervision.
For engineers reviewing the MAX6762TAWED3+ datasheet, MAX6762TAWED3+ pinout, MAX6762TAWED3+ application, or MAX6762TAWED3+ equivalent, key selection factors include dual-supply monitoring capability, OVLATCH-controlled OV latch behavior, TDFN-8 package thermal performance, and AEC-Q100 qualification for automotive use cases.
Technical Context
The MAX6762TAWED3+ implements independent UV/OV comparators for two supply rails-VCC (3.3V nominal) and VCC2 (1.8V nominal)-with internal reference trimming and SET-pin configurable ±5%/±10%/±15% window hysteresis. Its latched OV output remains asserted until cleared via OVLATCH, distinguishing it from non-latching variants.
It features a 26kΩ internal MR pullup, 10μA typical ICC at 3.6V, and guaranteed output validity down to VCC = 1.0V. The TDFN-8 package provides low θJA (41°C/W multilayer) and supports high-density PCB layouts in harsh-temperature environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - factory-trimmed primary supply monitoring rail |
| VCC2 Nominal Voltage | 1.8V - factory-trimmed secondary supply monitoring rail |
| Window Select | ±15% - configured by biasing SET pin to VCC/2 |
| Reset Timeout | 100ms min - ensures stable system reset after UV recovery |
| Supply Current | 13μA typ @ 3.6V - enables ultra-low-power battery-backed supervision |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial control |
| OVLATCH Function | Latched OV output - holds assertion until externally cleared, critical for fault logging |
Pinout & Package
MAX6762TAWED3+ is housed in an 8-pin TDFN package (outline 21-0137, land pattern 90-0059) with exposed pad (EP) internally connected to GND. Thermal resistance is 41°C/W (θJA, multilayer board), supporting high-reliability operation in thermally constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Active-low manual reset input | Asserts UV and RESET outputs; internally pulled up to VCC (26kΩ); 4µs min pulse width |
| 2 - OVLATCH | Overvoltage latch control | High = latch OV; low = clear latch; high-impedance input requiring external pullup/pulldown |
| 3 - UV | Active-low undervoltage output | Open-drain output (per MAX6762 suffix 'W'); asserts when VCC or VCC2 falls below UVTH |
| 4 - OV | Active-low overvoltage output | Open-drain output; latched behavior controlled by OVLATCH; no timeout delay |
| 5 - SET | Window threshold select | Bias to VCC/2 for ±15% window; GND = ±5%, VCC = ±10% |
| 6 - VCC2 | Secondary monitored supply | Input for 1.8V rail monitoring; powers device if VCC2 > VCC |
| 7 - GND | Ground reference | Common return for all analog and digital circuitry; EP must be connected to GND |
| 8 - VCC | Primary monitored supply | Input for 3.3V rail monitoring; also powers internal circuitry |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TAWED3+ | Identical pinout, package, and electrical specs; differs only in UV output polarity (push-pull active-high vs. MAX6762's open-drain active-low) | Requires level-shifting or logic inversion if interfacing with open-drain bus architectures | Select MAX6762TAWED3+ when open-drain UV output is required for wired-OR fault signaling |
| TPS3808G33DBVR | Single-supply (3.3V only), no VCC2 monitoring, no OVLATCH, SOT-23-6 package | Lacks dual-rail capability and latched fault reporting-unsuitable for systems requiring coordinated 3.3V/1.8V supervision | Choose only for cost-sensitive single-rail applications without latch or secondary supply needs |
Compared with MAX6761TAWED3+, MAX6762TAWED3+ provides open-drain UV output for direct bus integration; versus TPS3808G33DBVR, it adds essential dual-rail monitoring, OVLATCH, and AEC-Q100 compliance for automotive-grade systems.

FAQ
What is the function of the OVLATCH pin on the MAX6762TAWED3+?
The OVLATCH pin on the MAX6762TAWED3+ controls latching behavior of the OV output: driving OVLATCH high latches OV assertion during any VCC or VCC2 overvoltage event; driving it low clears the latch once overvoltage conditions are removed. When tied to GND, the latch is transparent-OV asserts and deasserts immediately with voltage transitions. This enables fault persistence for diagnostic logging without requiring continuous software polling.
Does the MAX6762TAWED3+ monitor both VCC and VCC2 simultaneously?
Yes, the MAX6762TAWED3+ monitors both VCC and VCC2 simultaneously and independently. VCC is factory-trimmed to 3.3V nominal and VCC2 to 1.8V nominal. An undervoltage or overvoltage condition on either rail asserts the corresponding UV or OV output. This dual-monitoring capability is intrinsic to the MAX6762TAWED3+ and does not require external configuration beyond proper supply connections.
What does the 'D3' suffix indicate in MAX6762TAWED3+?
The 'D3' suffix in MAX6762TAWED3+ specifies a 100ms minimum reset timeout period. After VCC or VCC2 recovers from an undervoltage condition, the RESET output remains asserted for at least 100ms (typ 185ms, max 320ms) to ensure stable microcontroller initialization. This contrasts with the 'D0' suffix, which provides a 20μs propagation delay only-no timeout-and is used where immediate deassertion is required.
Is the MAX6762TAWED3+ AEC-Q100 qualified?
Yes, the MAX6762TAWED3+ is AEC-Q100 qualified (Grade 1: -40°C to +125°C ambient). This qualification applies specifically to /V and /W suffix variants-including MAX6762TAWED3+-and covers stress testing for automotive reliability including temperature cycling, humidity bias, and ESD. Full qualification documentation is available from Analog Devices upon request.
What is the role of the SET pin on the MAX6762TAWED3+?
The SET pin on the MAX6762TAWED3+ selects the window hysteresis percentage: connecting SET to GND configures ±5%, to VCC configures ±10%, and biasing to VCC/2 (e.g., via resistor divider) configures ±15%. This adjusts both UVTH and OVTH thresholds symmetrically around their nominal values, allowing design flexibility to accommodate supply tolerance budgets without changing the IC itself.
