Product details
Overview
MAX6760TATGD3+T from Analog Devices is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (1.8V nominal) supplies with ±15% factory-trimmed thresholds, 100ms minimum reset timeout, latched overvoltage output, manual reset input, and operation from -40°C to +125°C. It asserts independent UV/OV outputs for power-rail integrity in telecom DC-DC modules.
For engineers reviewing the MAX6760TATGD3+T datasheet, MAX6760TATGD3+T pinout, MAX6760TATGD3+T application, or MAX6760TATGD3+T equivalent, key selection criteria include dual-rail monitoring capability, latched OV response, TDFN-8 package compatibility, and AEC-Q100 qualification for automotive-grade designs.
Technical Context
The MAX6760TATGD3+T implements two independent voltage comparators with internal reference and programmable window select via SET pin biasing to VCC/2 for ±15% tolerance. It features separate push-pull UV and open-drain OV outputs with latch control via OVLATCH pin.
It supports dual-supply monitoring where VCC = 3.3V (T suffix) and VCC2 = 1.8V (W suffix), with UVTH/VCC2 = 1.44V–1.71V and OVTH/VCC2 = 1.89V–2.16V across temperature, and includes MR input with 4µs minimum pulse width and 300ns propagation delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - primary supply monitored and powers device |
| VCC2 Nominal | 1.8V - secondary supply monitored; independent detection path |
| Window Tolerance | ±15% - set by biasing SET pin to VCC/2; enables robust margin against rail variation |
| Reset Timeout | 100ms min - ensures stable microprocessor reset after brownout recovery |
| Supply Current | 13µA typ at 3.6V - ultra-low power for always-on monitoring in battery-backed systems |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Output Types | UV: push-pull; OV: open-drain - allows flexible interface with MCU GPIO or external pull-up networks |
Pinout & Package
MAX6760TATGD3+T 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 efficiency (θJA = 41°C/W on multilayer board) and AEC-Q100 compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Active-low manual reset input | Asserts UV and resets latch; 26kΩ internal pullup; 4µs min pulse width required |
| 2 - OVLATCH | Overvoltage latch control | High = latch OV output; low = clear latch; high-impedance input requiring external pull |
| 3 - UV | Undervoltage output | Push-pull active-low; asserts when VCC or VCC2 falls below UVTH; deasserts after timeout |
| 4 - OV | Overvoltage output | Open-drain active-low; asserts immediately on OV condition; latched if OVLATCH = high |
| 5 - SET | Window threshold select | Bias to VCC/2 for ±15% window; sets hysteresis and tolerance band for both rails |
| 6 - VCC2 | Secondary monitored supply | Input for 1.8V rail monitoring; also powers device when VCC2 > VCC |
| 7 - GND | Ground reference | Common return for all analog/digital circuitry; EP must be connected to GND for thermal/signal integrity |
| 8 - VCC | Primary supply & monitor input | Powers device and monitors 3.3V rail; valid operation down to 1.0V with outputs asserted |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V (VCC) and 1.8V (VCC2) rails with separate UV/OV outputs and thresholds |
| Latched overvoltage response | OVLATCH pin enables persistent OV assertion until cleared-critical for fault logging and safety shutdown |
| Factory-trimmed ±15% window | Eliminates external resistor dividers; SET pin biased to VCC/2 configures full tolerance without calibration |
| 100ms reset timeout | Guarantees sufficient hold time for microprocessor initialization after power recovery |
| Low 13µA supply current | Enables continuous monitoring in energy-constrained applications such as remote sensors and telematics |

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 |
|---|---|---|---|
| MAX6761TATGD3+T | Same pinout and electrical specs; differs only in UV output polarity (active-high push-pull vs. active-low) | Requires inverted logic handling in MCU firmware; otherwise drop-in for same rail voltages and timing | Select when system design expects active-high UV signal to simplify GPIO interrupt routing |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OV latch, no SET-adjustable window; SOT-23-3 package | Cannot replace dual-rail functionality; suitable only for cost-sensitive single-rail applications without latching | Use only if monitoring one rail and accepting loss of latch, dual detection, and ±15% flexibility |

FAQ
What voltage rails does the MAX6760TATGD3+T monitor?
The MAX6760TATGD3+T monitors two independent voltage rails: VCC at 3.3V nominal (T suffix) and VCC2 at 1.8V nominal (W suffix). Both rails are supervised simultaneously with dedicated undervoltage and overvoltage comparators, enabling coordinated fault response in multi-rail systems like telecom DC-DC modules and automotive ADAS controllers.
How is the ±15% window threshold configured on the MAX6760TATGD3+T?
The ±15% window threshold on the MAX6760TATGD3+T is configured by biasing the SET pin to VCC/2 using a resistive divider. This setting selects the widest factory-trimmed tolerance band for both VCC and VCC2 thresholds, eliminating need for external calibration while ensuring robust operation across temperature and supply variation.
Does the MAX6760TATGD3+T provide latched overvoltage detection?
Yes, the MAX6760TATGD3+T provides latched overvoltage detection via the OVLATCH pin. When OVLATCH is driven high, the OV output remains asserted even after the overvoltage condition clears-enabling fault capture and diagnostic logging. The latch is cleared only when OVLATCH is driven low after overvoltage removal.
What is the reset timeout period of the MAX6760TATGD3+T?
MAX6760TATGD3+T has a D3-suffix indicating a 100ms minimum reset timeout period. After VCC or VCC2 recovers above its UV threshold, the RESET/UV output remains asserted for ≥100ms before deassertion-ensuring reliable microprocessor initialization and state recovery in embedded systems.
Is the MAX6760TATGD3+T qualified for automotive applications?
Yes, the MAX6760TATGD3+T is AEC-Q100 qualified (Grade 1, -40°C to +125°C), making it suitable for automotive applications including ADAS cameras, infotainment power management, and body control modules where dual-rail supervision and latch-based fault reporting are required.
