Product details
Overview
The MAX6760TATZD3 from Maxim Integrated is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (2.5V nominal) supply rails for undervoltage and overvoltage conditions, with ±10% factory-trimmed thresholds, 100ms minimum reset timeout, push-pull UV output, open-drain OV output, manual reset input, and latched overvoltage functionality - used in microprocessor power supervision for telecom and industrial embedded systems.
For engineers reviewing the MAX6760TATZD3 datasheet, MAX6760TATZD3 pinout, MAX6760TATZD3 application, or MAX6760TATZD3 equivalent, key selection criteria include dual-rail monitoring capability, latched OV behavior, TDFN-8 package compatibility, -40°C to +125°C operation, and 10µA supply current at 3.6V.
Technical Context
The MAX6760TATZD3 implements independent voltage comparators for VCC and VCC2, each with programmable ±10% window via SET pin tied to VCC, and features a latched OV output controlled by OVLATCH. It asserts UV when either rail falls below its UVTH or MR is pulled low, and asserts OV when either rail exceeds its OVTH - with latch persistence until cleared.
Its timing architecture includes a 100ms minimum reset timeout (D3 option) after UV recovery, 20µs propagation delay for UV/OV assertion, and startup delay of 2ms for OV output. The device operates with VCC ≥ 1.4V (outputs valid down to 1.0V) and supports VCC2 monitoring from 0.9V to 5V via external divider when configured as adjustable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - primary monitored supply and device power source |
| VCC2 Nominal | 2.5V - secondary monitored supply, internally trimmed |
| OV/UV Window | ±10% - set by connecting SET pin to VCC; enables robust noise margin |
| Reset Timeout | 100ms min - ensures stable µP reset after supply recovery |
| Supply Current | 13µA typ at 3.6V - enables ultra-low-power system supervision |
| Operating Temp | -40°C to +125°C - qualified for automotive and industrial environments |
| Output Types | Push-pull UV, open-drain OV, active-low MR - supports direct µP interface without pull-ups |
Pinout & Package
MAX6760TATZD3 is housed in an 8-pin TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input / Primary Monitor Rail | Supplies device and serves as first monitored voltage (3.3V nominal) |
| 2 - GND | Ground Reference | Common return for all internal circuits and outputs |
| 3 - VCC2 | Secondary Monitor Rail Input | Input for second monitored supply (2.5V nominal); powers device if VCC2 > VCC |
| 4 - UV | Undervoltage Output | Active-low push-pull output asserted when VCC or VCC2 falls below UVTH |
| 5 - OV | Overvoltage Output | Active-low open-drain output asserted when VCC or VCC2 exceeds OVTH; latched via OVLATCH |
| 6 - MR | Manual Reset Input | Active-low input with 26kΩ internal pull-up; forces UV assertion on falling edge |
| 7 - OVLATCH | Latch Control Input | High-impedance input; high = latch OV, low = clear latch, GND = transparent mode |
| 8 - SET | Window Threshold Select | Connected to VCC for ±10% window; GND = ±5%, bias to VCC/2 = ±15% |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of VCC (3.3V) and VCC2 (2.5V) with separate UV/OV detection paths |
| Latched overvoltage output | OVLATCH pin enables persistent OV assertion until cleared - critical for fault logging and safety shutdown |
| Factory-trimmed ±10% window | Eliminates external resistor networks; achieves ±1.5% total threshold accuracy over temperature |
| 100ms minimum reset timeout | Guarantees µP reset pulse width meets ARM/Cortex and x86 requirements after brownout recovery |
| Low 13µA supply current | Reduces standby power in battery-backed or energy-harvesting systems without compromising response speed |

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 |
|---|---|---|---|
| MAX6761TATZD3 | Identical pinout, package, and electrical specs; differs only in UV output polarity (active-high push-pull vs. MAX6760's active-low) | Requires inverted logic handling in µP reset input; no change to OV or latch behavior | Select when host processor requires active-high reset assertion. |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OVLATCH, no SET-adjustable window, SOT23-3 package | Cannot replace dual-rail function; suitable only for simplified single-rail backup monitoring | Use only where VCC2 supervision is unnecessary and board space allows separate devices. |
Compared with MAX6761TATZD3, the MAX6760TATZD3 provides native active-low UV for direct connection to standard µP reset pins; compared with TLV809E33DBZR, it delivers full dual-rail supervision, latch control, and window configurability - making it irreplaceable in coordinated multi-rail power integrity designs.

FAQ
What is the exact VCC and VCC2 threshold voltage for MAX6760TATZD3?
The MAX6760TATZD3 has factory-trimmed thresholds: VCC nominal = 3.3V with ±10% window → OVTH = 3.63V (min), UVTH = 2.97V (max); VCC2 nominal = 2.5V with ±10% window → OVTH2 = 2.75V (min), UVTH2 = 2.25V (max). These values are guaranteed over -40°C to +125°C per the datasheet's Electrical Characteristics table.
Does MAX6760TATZD3 support adjustable VCC2 thresholds?
No - the MAX6760TATZD3 uses fixed internal trimming for VCC2 at 2.5V. Adjustable VCC2 monitoring is only available on MAX6760 variants with suffix 'A' (e.g., MAX6760TAAAD3), which require an external resistor divider to set VCC2 to 0.4255V. The 'TZ' suffix confirms fixed 2.5V VCC2.
How does the OVLATCH function behave in MAX6760TATZD3?
In the MAX6760TATZD3, driving OVLATCH high latches the OV output in its asserted (low) state regardless of subsequent VCC/VCC2 levels; driving OVLATCH low clears the latch only after both supplies return within their OV windows. When OVLATCH is grounded, the OV output operates transparently (no latch).
What is the purpose of the SET pin on MAX6760TATZD3?
The SET pin on MAX6760TATZD3 selects the voltage window tolerance: tied to VCC for ±10% (as in this part), GND for ±5%, or biased to VCC/2 for ±15%. This configures hysteresis and threshold spread without external components - critical for noise immunity in electrically noisy environments.
Can MAX6760TATZD3 operate with VCC below 1.4V?
Yes - the MAX6760TATZD3 functions with VCC ≥ 1.4V for full monitoring and output assertion, but its RESET, UV, and OV outputs remain in correct logic state (asserted/deasserted as appropriate) even when VCC drops to 1.0V, enabling graceful fail-safe behavior during deep brownouts.
