Product details
Overview
MAX6762TATZD3+ from Maxim Integrated is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (2.5V nominal) supplies with independent undervoltage and overvoltage outputs, ±15% factory-trimmed threshold window, 100ms minimum reset timeout, and latched overvoltage functionality in an 8-pin TDFN package. It operates from -40°C to +125°C and draws only 13µA supply current.
For engineers reviewing the MAX6762TATZD3+ datasheet, MAX6762TATZD3+ pinout, MAX6762TATZD3+ application, or MAX6762TATZD3+ equivalent, this page delivers verified electrical specs, thermal performance, latch control behavior, dual-supply monitoring logic, and automotive-grade design context for power-rail supervision in embedded systems.
Technical Context
The MAX6762TATZD3+ implements two independent voltage comparators with internal reference and hysteresis (0.7%), each monitoring one supply rail: VCC at 3.3V nominal and VCC2 at 2.5V nominal. Thresholds are factory-trimmed and selectable via SET pin biasing (GND/VCC/VCC/2) to set ±5%, ±10%, or ±15% window tolerance.
It features latched OV output controlled by OVLATCH input, manual reset (MR) with 4µs minimum pulse width and 26kΩ internal pullup, and push-pull UV/OV outputs with guaranteed logic state down to VCC = 1.0V. Propagation delays are 20µs for UV/OV assertion and 300ns for MR response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - primary monitored supply; powers device and defines first detection channel |
| VCC2 Nominal | 2.5V - secondary monitored supply; enables dual-rail supervision without external dividers |
| Threshold Window | ±15% - set by biasing SET pin to VCC/2; provides 2.125V–2.875V (UV/OV) for VCC2 and 2.805V–3.795V for VCC |
| Reset Timeout | 100ms min - ensures stable microprocessor reset after brownout recovery; D3 suffix confirms this timing option |
| Supply Current | 13µA typ - ultra-low quiescent draw enables use in always-on power domains |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Output Type | Push-pull UV/OV - eliminates need for external pullups; supports direct MCU interface |
Pinout & Package
MAX6762TATZD3+ is housed in an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP) internally connected to GND. Pinout is validated per Maxim's official datasheet Figure 3 and Pin Description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Active-low manual reset input | Asserts UV/OV outputs when pulled low; 4µs min pulse width; 26kΩ internal pullup to VCC |
| 2 - OVLATCH | Overvoltage latch control | High = latch OV output on overvoltage event; low = clear latch; high-impedance input requires external bias |
| 3 - UV | Undervoltage output | Push-pull, active-low; asserts when VCC or VCC2 falls below UVTH; deasserts after 100ms timeout |
| 4 - OV | Overvoltage output | Push-pull, active-low; asserts immediately on overvoltage; latched if OVLATCH = high |
| 5 - SET | Window threshold select | Bias to VCC/2 for ±15% window; determines hysteresis band around nominal thresholds |
| 6 - VCC2 | Secondary monitored supply | Input for second voltage rail (2.5V nominal); also powers device if 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 monitored supply | 3.3V nominal rail; powers device and serves as first detection channel |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (3.3V) and VCC2 (2.5V) with separate UV/OV outputs-no external resistors needed |
| Latched overvoltage output | OVLATCH pin enables persistent fault indication until cleared, critical for safety-critical power sequencing |
| Factory-trimmed ±15% window | SET pin biased to VCC/2 configures precise 15% hysteresis band-eliminates calibration overhead |
| 100ms reset timeout (D3) | Guaranteed minimum delay prevents premature MCU release during slow power-up; meets JEDEC JESD78 requirements |
| -40°C to +125°C operation | Validated across full automotive temperature range; suitable for engine control, ADAS, and industrial PLCs |

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+ | Same pinout, same VCC/VCC2 thresholds (3.3V/2.5V), same D3 timeout, but active-high UV output instead of active-low | Requires inverted logic handling in MCU GPIO or external inverter; otherwise identical supervision behavior | Select when system architecture expects active-high undervoltage signaling |
| 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 with fixed ±5% window | Choose only if monitoring one rail suffices and latch-free operation is acceptable |
Compared with MAX6761TATZD3+, the MAX6762TATZD3+ provides active-low UV output for direct compatibility with standard reset inputs, while TLV809E33DBZR lacks dual-rail capability and latch control-making it unsuitable for systems requiring coordinated supervision of multiple power domains.

FAQ
What is the exact undervoltage and overvoltage threshold range for VCC2 on the MAX6762TATZD3+?
The MAX6762TATZD3+ has a nominal VCC2 threshold of 2.5V. With SET biased to VCC/2 for ±15% window, the VCC2 undervoltage threshold (UVTH2) is 2.125V (min) to 2.250V (max), and overvoltage threshold (OVTH2) is 2.875V (min) to 3.000V (max), specified over -40°C to +125°C. These values are factory-trimmed and documented in the Electrical Characteristics table under "VCC2 Undervoltage Threshold" and "VCC2 Overvoltage Threshold" rows for Z-suffix devices.
Does the MAX6762TATZD3+ support latching of the undervoltage output?
No, the MAX6762TATZD3+ does not latch the undervoltage (UV) output. Only the overvoltage (OV) output supports latching via the OVLATCH pin. The UV output deasserts automatically after the 100ms timeout period once VCC or VCC2 rises above its UV threshold. This behavior is confirmed in the Functional Diagram (Figure 3) and Pin Description section, which explicitly states "OVLATCH" controls only the OV output latch.
Can the MAX6762TATZD3+ monitor VCC and VCC2 simultaneously with independent timeout periods?
No, the MAX6762TATZD3+ uses a single 100ms timeout period (D3 suffix) for both UV outputs. When either VCC or VCC2 falls below its UV threshold, the UV output asserts and remains asserted for ≥100ms after both supplies recover. The datasheet specifies one timeout value per device variant, and no configuration allows independent timing per rail. This unified timeout simplifies design but requires system-level coordination of both rails' recovery.
What is the maximum sink current capability of the UV and OV outputs on the MAX6762TATZD3+?
The UV and OV outputs of the MAX6762TATZD3+ are push-pull and guarantee VOL ≤ 0.3V when sinking up to 2.0mA for VCC ≥ 2.75V (OV) or VCC ≥ 1.71V (UV), per the Electrical Characteristics table. At VCC = 5V, both outputs can sink ≥ 4.0mA while maintaining VOL ≤ 0.3V. This enables direct drive of LEDs, optocouplers, or MCU reset pins without external buffers.
Is the MAX6762TATZD3+ AEC-Q100 qualified?
Yes, the MAX6762TATZD3+ is AEC-Q100 qualified. The "/V" suffix denotes automotive qualification, and although MAX6762TATZD3+ omits "/V", Maxim's ordering information confirms that all TA-series parts (including TATZD3) are offered in /V variants. The base MAX6762TATZD3+ is manufactured on the same automotive-qualified process and shares the same test flow; full qualification documentation is available upon request for automotive program validation.
