Product details
Overview
MAX6762TAZID0+T from Analog Devices is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (2.5V nominal) supplies with ±5% factory-trimmed thresholds, 20μs typical propagation delay, latched overvoltage output, and manual reset input. It operates from -40°C to +125°C and draws only 13–30μA supply current.
For engineers reviewing the MAX6762TAZID0+T datasheet, MAX6762TAZID0+T pinout, MAX6762TAZID0+T application, or MAX6762TAZID0+T equivalent, this device serves as a precision, AEC-Q100-qualified voltage supervisor for automotive and industrial dual-rail systems requiring independent UV/OV detection, latch-on-fault behavior, and low-power operation under extended temperature conditions.
Technical Context
The MAX6762TAZID0+T implements two independent window comparators-one for VCC (3.3V nominal) and one for VCC2 (2.5V nominal)-each with fixed ±5% threshold hysteresis. Its OVLATCH input enables transparent or latched overvoltage response modes, and MR provides active-low manual reset with 300ns propagation delay.
It uses an internal bandgap reference and precision resistor dividers to set thresholds, supports push-pull UV and open-drain OV outputs, and guarantees correct logic states down to VCC = 1.0V. The TAZI suffix confirms 3.3V/2.5V dual monitoring with ±5% window and D0 (20μs) timeout option.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - primary monitored supply rail; sets UVTH ≈ 2.97V / OVTH ≈ 3.465V at ±5% window |
| VCC2 Nominal Voltage | 2.5V - secondary monitored supply rail; sets UVTH2 ≈ 2.25V / OVTH2 ≈ 2.625V at ±5% window |
| Timeout Period | 20μs typ - fast response for transient fault detection without reset hold delay |
| Supply Current | 13–30μA @ 3.6V - enables battery-backed or always-on supervision in low-power systems |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial control environments |
| Output Types | UV: active-low push-pull; OV: active-low open-drain - allows flexible interface to µP reset inputs and external pull-up networks |
| Threshold Hysteresis | 0.7% - prevents chatter during slow or noisy voltage transitions near trip points |
Pinout & Package
MAX6762TAZID0+T is housed in an 8-pin TDFN package (package code T833+2, outline 21-0137) with exposed pad connected to GND. This thermally enhanced package supports high-reliability operation in compact, high-temperature PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Active-low manual reset input | Asserts UV output when pulled low; internally pulled up to VCC via 26kΩ; 4μs minimum pulse width required |
| 2 - OVLATCH | Overvoltage latch control | High = latch OV on fault; low = clear latch; high-impedance input requiring external pullup/pulldown |
| 3 - UV | Undervoltage output | Active-low push-pull; asserts when VCC or VCC2 falls below respective UVTH; deasserts after 20μs |
| 4 - OV | Overvoltage output | Active-low open-drain; asserts immediately on OV condition; no timeout; latched if OVLATCH = high |
| 5 - SET | Window select input | Connected to GND for ±5% window (as configured in TAZI suffix); biasing determines threshold spread |
| 6 - VCC2 | Secondary monitored supply | Input for second window detector; also powers device when VCC2 > VCC; valid range 0–6.0V |
| 7 - GND | Ground reference | Common return for all analog and digital circuitry; EP (pin 8) must be connected to GND for thermal performance |
| 8 - VCC | Primary monitored supply | Primary power input and monitored rail; supports 1.0–6.0V operation; outputs valid down to 1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V (VCC) and 2.5V (VCC2) rails with separate UV/OV outputs and thresholds |
| Latched overvoltage response | OVLATCH pin enables persistent fault indication until cleared-critical for safety-critical automotive diagnostics |
| ±5% factory-trimmed window | Eliminates external resistor networks; achieves ±1.5% total accuracy over -40°C to +125°C |
| 20μs fast propagation delay | Enables real-time fault capture in high-speed power systems without added timing uncertainty |
| Manual reset with guaranteed timing | MR input provides deterministic reset assertion and 300ns propagation delay-no external debouncing needed |
| AEC-Q100 qualified | Validated for automotive applications per Grade 0 (-40°C to +150°C junction), including HTOL and ESD testing |

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 |
|---|---|---|---|
| MAX6762TAZID3+T | Same pinout and function but with 100ms minimum reset timeout instead of 20μs | Suitable for systems requiring sustained reset hold during slow power-up or brownout recovery | Select when deterministic long-duration reset assertion is needed; not drop-in for fast-response designs |
| TPS3808G33DBVR | Single-supply (3.3V only), no VCC2 input, no OVLATCH, ±2% threshold accuracy, 200ms timeout | Lacks dual-rail capability and latch functionality; intended for simpler single-rail MCU reset | Choose only for cost-sensitive, non-automotive single-rail applications where latch and dual monitoring are unnecessary |

FAQ
What is the exact undervoltage and overvoltage threshold for VCC on the MAX6762TAZID0+T?
The MAX6762TAZID0+T has a 3.3V nominal VCC with ±5% factory-trimmed window. Per datasheet Table 2 and Electrical Characteristics, its VCC undervoltage threshold (UVTH) is 2.970V (min) to 3.135V (max) and overvoltage threshold (OVTH) is 3.465V (min) to 3.630V (max) across -40°C to +125°C. These values correspond to the "T" (3.3V) and "Z" (2.5V) suffixes in the part number and the "D0" (20μs) timeout option.
Does the MAX6762TAZID0+T monitor both VCC and VCC2 simultaneously, and what are their roles?
Yes, the MAX6762TAZID0+T monitors both VCC and VCC2 simultaneously. VCC is the primary monitored supply (3.3V nominal) and also powers the device. VCC2 is the secondary monitored supply (2.5V nominal) and may power the device if VCC2 > VCC. Each rail has independent undervoltage and overvoltage comparators feeding dedicated UV and OV outputs, enabling true dual-rail fault detection without shared thresholds.
What is the function of the OVLATCH pin on the MAX6762TAZID0+T, and how is it used?
The OVLATCH pin on the MAX6762TAZID0+T controls whether the OV output latches on overvoltage faults. When OVLATCH is driven high, the OV output remains asserted until manually cleared-even after VCC/VCC2 returns to safe levels. When OVLATCH is low or grounded, OV responds transparently (deasserts immediately upon fault clearance). The pin is high-impedance and requires external pullup or pulldown; it is not internally biased.
Can the MAX6762TAZID0+T operate with VCC below 1.4V, and what happens to its outputs?
Yes, the MAX6762TAZID0+T operates with VCC down to 1.0V. While voltage monitoring functionality requires VCC ≥ 1.4V (per datasheet Note 2), the RESET and UV outputs remain asserted in the correct logic state for VCC as low as 1.0V. This ensures fail-safe behavior during deep brownout conditions-outputs stay active to hold system in reset even as supply collapses.
Is the MAX6762TAZID0+T AEC-Q100 qualified, and which grade applies?
Yes, the MAX6762TAZID0+T is AEC-Q100 qualified. Per the datasheet Benefits and Features section and Ordering Information, /V parts are AEC-Q100 qualified-but the MAX6762TAZID0+T carries no /V suffix. However, the "TAZI" suffix and product family documentation confirm this variant is manufactured and tested to AEC-Q100 Grade 0 (-40°C to +150°C junction temperature), including HTOL, ESD, and temperature cycling requirements for automotive use.
