Product details
Overview
MAX6760TAWED3+ from Maxim Integrated is a dual-voltage window detector IC designed to monitor undervoltage and overvoltage conditions on two independent power rails-VCC (1.8V nominal) and VCC2 (0.9V nominal)-with ±15% factory-trimmed window tolerance, 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 DC-DC converter modules and automotive control units.
For engineers reviewing the MAX6760TAWED3+ datasheet, MAX6760TAWED3+ pinout, MAX6760TAWED3+ application, or MAX6760TAWED3+ equivalent, key selection considerations include its dual-rail monitoring capability, latched OV output for fault retention, AEC-Q100-compatibility (indicated by /V suffix-though this part lacks /V, it shares the same die and package qualification path), 10µA typical supply current, and TDFN-8 package with exposed pad.
Technical Context
The MAX6760TAWED3+ implements dual independent voltage comparators with internal precision reference and programmable window select via the SET pin (biased to VCC/2 for ±15%). It monitors VCC (1.8V nominal) and VCC2 (0.9V nominal) simultaneously, asserting UV and OV outputs when either rail breaches its respective threshold.
It features a latched overvoltage output controlled by OVLATCH, a manual reset input (MR) with 26kΩ internal pullup, and push-pull UV/RESET outputs with guaranteed logic state down to VCC = 1.0V. The 100ms minimum timeout (D3 suffix) applies to RESET deassertion after UV recovery, while OV responds within 20µs with no timeout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 1.8V - primary monitored supply; factory-trimmed threshold with ±15% window (SET = VCC/2) |
| VCC2 Nominal Voltage | 0.9V - secondary monitored supply; factory-trimmed threshold with ±15% window (SET = VCC/2) |
| Reset Timeout Period | 100ms min - ensures stable microprocessor reset hold time after undervoltage recovery |
| Supply Current (ICC) | 13µA typ at VCC = 3.6V - enables ultra-low-power supervision in always-on automotive domains |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| Output Configuration | Push-pull UV and RESET; open-drain OV - supports direct MCU interface without external pullups for UV/RESET |
| Threshold Hysteresis | 0.7% - prevents chatter during slow or noisy supply transitions |
Pinout & Package
MAX6760TAWED3+ is housed in an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP) internally connected to GND. The package supports high thermal dissipation and compact PCB layout for space-constrained automotive modules.
| 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 minimum pulse width |
| 2 - OVLATCH | Overvoltage latch control input | High = latch OV output until cleared; low = transparent mode; high-impedance, requires external bias |
| 3 - UV | Active-low undervoltage output | Push-pull; asserts when VCC or VCC2 falls below UVTH; deasserts after 100ms timeout |
| 4 - OV | Active-low overvoltage output | Open-drain; asserts immediately on OV condition; latched if OVLATCH = high; no timeout |
| 5 - SET | Window threshold select input | Bias to VCC/2 for ±15% window; determines hysteresis width for both VCC and VCC2 detectors |
| 6 - VCC2 | Secondary monitored supply input | Monitors 0.9V rail; also powers device when VCC2 > VCC; valid down to 0V |
| 7 - GND | Ground reference | Common return for all analog and digital circuitry; EP must be connected to GND for thermal and EMI performance |
| 8 - VCC | Primary monitored supply input | Monitors 1.8V rail; powers internal circuitry; outputs valid for VCC ≥ 1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 1.8V (VCC) and 0.9V (VCC2) rails with separate UV/OV outputs and thresholds |
| Latched overvoltage output | OVLATCH pin enables persistent fault flagging until manually cleared-critical for diagnostic logging in automotive ECUs |
| ±15% window tolerance (SET = VCC/2) | Wider hysteresis reduces false trips on noisy 0.9V core supplies common in low-power microcontrollers |
| 100ms minimum reset timeout (D3 suffix) | Guarantees sufficient reset assertion time for complex SoCs requiring extended power-up stabilization |
| AEC-Q100 design-in readiness | Same die, process (BiCMOS), and TDFN-8 package as /V-qualified variants; supports automotive-grade reliability validation |
| Low 13µA supply current | Enables integration into always-on domains (e.g., CAN wake-up circuits) without compromising battery life |
Applications
| Automotive Body Control Module | Industrial PLC I/O Power Supervision |

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 |
|---|---|---|---|
| MAX6761TAWED3+ | Identical electrical specs and pinout; differs only in UV output polarity (active-high push-pull vs. active-low in MAX6760) | Suitable where MCU requires active-high reset assertion; no PCB change needed if pullup/pulldown logic accommodates polarity | Select MAX6761TAWED3+ only when system reset controller expects active-high UV signal |
| TLV809EADL33DBVR | Single-supply (3.3V only), no VCC2 monitoring, no OVLATCH, no manual reset, SOT-23-5 package | Limited to basic 3.3V rail supervision; cannot replace dual-rail functionality or latch requirement | Use only for cost-sensitive single-rail applications where dual monitoring and fault latching are unnecessary |
Compared with MAX6761TAWED3+, the MAX6760TAWED3+ provides active-low UV output compatible with legacy reset controllers, while TLV809EADL33DBVR lacks dual-rail capability and fault retention-making it unsuitable for automotive or safety-critical dual-supply systems.

FAQ
What is the function of the SET pin on the MAX6760TAWED3+?
The SET pin on the MAX6760TAWED3+ selects the window tolerance for both VCC and VCC2 thresholds. When biased to VCC/2 (as indicated by the 'W' and 'E' suffixes), it configures a ±15% window-ensuring robust immunity to noise on the 1.8V and 0.9V rails. This setting is fixed at manufacture and verified per datasheet Table 2.
Does the MAX6760TAWED3+ support AEC-Q100 qualification?
The MAX6760TAWED3+ uses the same BiCMOS die and TDFN-8 package as AEC-Q100-qualified /V variants (e.g., MAX6760TAWED3/V+). While this specific part number lacks the /V suffix, its design, process, and package meet automotive stress test requirements-enabling qualification-ready deployment in non-safety-critical automotive subsystems.
How does the OVLATCH pin affect the OV output behavior of the MAX6760TAWED3+?
When OVLATCH is driven high, the MAX6760TAWED3+ latches the OV output in asserted (low) state upon any overvoltage event on VCC or VCC2-holding it until OVLATCH is pulled low. This enables fault retention for diagnostics. With OVLATCH tied to GND, OV operates transparently (deasserts immediately when voltage returns to spec).
What are the absolute maximum ratings for VCC and VCC2 on the MAX6760TAWED3+?
The MAX6760TAWED3+ allows VCC and VCC2 inputs from -0.3V to +6.5V. However, functional monitoring requires VCC ≥ 1.4V (per Note 2), and outputs remain valid down to VCC = 1.0V. VCC2 may be 0V during standby, but monitoring activates only when VCC2 ≥ 0.9V nominal.
Can the MAX6760TAWED3+ monitor voltages lower than 0.9V on VCC2?
No-the MAX6760TAWED3+ is factory-trimmed for 0.9V nominal on VCC2 (suffix 'E'). It does not support adjustable thresholds like the MAX6763/MAX6764. For sub-0.9V monitoring, an external resistor divider feeding a MAX6763/MAX6764 is required, as confirmed in the Adjustable Bias Current specification (±20nA) and Table 2.
