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) for undervoltage/overvoltage conditions with ±15% factory-trimmed window, 100ms minimum reset timeout, latched overvoltage output, manual reset input, and operation from -40°C to +125°C. It serves as a system power supervisor in DC-DC converter modules and automotive electronics.
For engineers reviewing the MAX6760TATZD3+ datasheet, MAX6760TATZD3+ pinout, MAX6760TATZD3+ application, or MAX6760TATZD3+ equivalent, key selection criteria include dual-supply monitoring capability, latched OV output behavior, ±15% window select via SET pin, 100ms D3 timeout option, and TDFN-8 package compatibility with high-temperature industrial environments.
Technical Context
The MAX6760TATZD3+ implements two independent voltage comparators with internal reference and hysteresis (0.7%), one for VCC (3.3V nominal) and one for VCC2 (2.5V nominal), each with programmable ±5%/±10%/±15% window via SET pin. It features separate push-pull UV and open-drain OV outputs, with OV latch control via OVLATCH pin.
Its timing architecture includes a 100ms minimum reset timeout (D3 suffix), 20μs propagation delay on MR assertion, and startup delay of 2ms for OV output. The device operates with VCC ≥ 1.4V (outputs valid down to 1.0V) and VCC2 ≥ 0V, drawing only 13–30μA supply current at 3.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - Factory-trimmed threshold for primary supply monitoring |
| VCC2 Nominal Voltage | 2.5V - Factory-trimmed threshold for secondary supply monitoring |
| Window Tolerance | ±15% - Set by biasing SET pin to VCC/2; enables robust margin against supply drift |
| Reset Timeout Period | 100ms min - Ensures stable microprocessor reset during brownout recovery |
| Supply Current | 13–30μA at 3.6V - Enables use in always-on, low-power systems |
| Operating Temperature | -40°C to +125°C - Qualified for under-hood automotive and industrial environments |
| OV Latch Function | Yes - OVLATCH pin controls persistent OV assertion until cleared |
Pinout & Package
MAX6760TATZD3+ is housed in an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP) internally connected to GND. Pin 1 is MR, Pin 2 is OVLATCH, Pin 3 is UV, Pin 4 is OV, Pin 5 is SET, Pin 6 is VCC2, Pin 7 is GND, Pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Active-low manual reset input | Asserts UV and RESET outputs immediately; deassertion delayed by tMR_P (100–320ms) |
| 2 (OVLATCH) | Overvoltage latch control | High = latch OV output; low = clear latch; GND = transparent mode |
| 3 (UV) | Undervoltage output | Push-pull, active-low; asserts when VCC or VCC2 falls below UVTH |
| 4 (OV) | Overvoltage output | Open-drain, active-low; latched if OVLATCH high; no timeout |
| 5 (SET) | Window tolerance select | Bias to VCC/2 for ±15% window; GND = ±5%, VCC = ±10% |
| 6 (VCC2) | Secondary monitored supply | Input for second voltage monitor; also powers device if VCC2 > VCC |
| 7 (GND) | Ground reference | Common return for all analog and digital circuitry; EP tied to this node |
| 8 (VCC) | Primary monitored supply | Primary input voltage (3.3V nominal); powers internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V (VCC) and 2.5V (VCC2) rails with separate UV/OV outputs |

| Factory-trimmed ±15% window | Eliminates external resistor networks; reduces BOM count and layout area vs. adjustable solutions |
| 100ms minimum reset timeout (D3) | Guarantees sufficient hold time for microprocessor initialization after power recovery |
| Low 10μA quiescent current | Enables integration into battery-backed or energy-harvesting subsystems without significant drain |
| AEC-Q100 qualified option | Available in /V automotive-grade variant (MAX6760TATZD3+/V); not applicable to standard + suffix |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage window detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TATZD3+ | Active-high UV output (vs. active-low on MAX6760TATZD3+); identical thresholds, timing, and pinout | Requires inverted logic handling in host MCU GPIO or external inverter; same PCB layout | Select when system design expects high-asserted UV signal for direct MCU interrupt |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OV latch, no SET-adjustable window | Limited to single-rail systems; cannot replace dual-monitoring function without adding second IC | Consider only for cost-sensitive, single-rail applications where latching and dual monitoring are unnecessary |
Compared with MAX6761TATZD3+, the MAX6760TATZD3+ provides active-low UV output compatible with standard reset-interrupt inputs, while TLV809E33DBZR lacks dual-rail capability and fault latching-making it unsuitable as a drop-in replacement but viable for simplified single-supply designs.

FAQ
What is the function of the SET pin on the MAX6760TATZD3+?
The SET pin on the MAX6760TATZD3+ selects the undervoltage/overvoltage window tolerance: connecting to GND yields ±5%, to VCC yields ±10%, and biasing to VCC/2 yields ±15%. For MAX6760TATZD3+, the Z suffix indicates 2.5V VCC2 nominal, and the T suffix indicates 3.3V VCC nominal-so SET configures the window around those fixed thresholds. This eliminates external resistor dividers and ensures consistent performance across temperature.
Does the MAX6760TATZD3+ support latched overvoltage detection?
Yes, the MAX6760TATZD3+ supports 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 for diagnostics. Driving OVLATCH low clears the latch. The MAX6760TATZD3+ datasheet confirms this function is implemented in the MAX6760/MAX6761/MAX6762 family, and the TATZD3+ variant includes it as a core feature.
What are the absolute maximum ratings for VCC and VCC2 on the MAX6760TATZD3+?
The MAX6760TATZD3+ has absolute maximum ratings of -0.3V to +6.5V on VCC and VCC2 pins. However, functional operation requires VCC ≥ 1.4V (outputs remain asserted down to 1.0V), and VCC2 can operate from 0V to 6.0V. These limits ensure robustness against transient overvoltage events while maintaining guaranteed operation across the full -40°C to +125°C temperature range.
How does the 100ms reset timeout (D3 suffix) behave during power-up?
The 100ms reset timeout (D3 suffix) on the MAX6760TATZD3+ applies to the RESET/UV deassertion delay after VCC or VCC2 rises above UVTH. During initial power-up, the device asserts UV/RESET immediately and holds it for ≥100ms (min) after valid voltage is detected-ensuring microprocessors complete internal initialization. Startup delay for OV output is 2ms (per datasheet Note 4), independent of the D3 timeout.
Is the MAX6760TATZD3+ pin-compatible with other MAX6760 variants?
Yes, all MAX6760 variants-including MAX6760TATZD3+-use the same 8-pin TDFN package and identical pinout (MR, OVLATCH, UV, OV, SET, VCC2, GND, VCC). Differences lie only in threshold voltages (T=3.3V, Z=2.5V), window tolerance (determined by SET connection), and timeout option (D3=100ms min). This allows design reuse across voltage combinations without PCB changes.
