Product details
Overview
MAX6762TATAD0+ from Analog Devices is a dual-voltage window detector IC monitoring both VCC (3.3V nominal) and VCC2 (adjustable down to 0.9V) with independent undervoltage/overvoltage outputs, ±10% factory-set window tolerance, 20μs typical reset timeout, manual reset input, and latched overvoltage output - used in telecom power supervision and automotive DC-DC converter modules.
For engineers reviewing the MAX6762TATAD0+ datasheet, MAX6762TATAD0+ pinout, MAX6762TATAD0+ application, or MAX6762TATAD0+ equivalent, key selection criteria include dual-supply monitoring capability, latch-enabled OV response, -40°C to +125°C operation, SOT23-6 package compatibility, and AEC-Q100 qualification for automotive-grade designs.
Technical Context
The MAX6762TATAD0+ implements two independent voltage comparators with internal reference and programmable window width via SET pin (configured to VCC for ±10%). It monitors VCC (3.3V nominal) and VCC2 (adjustable via external divider to 0.9–3.3V), asserting UV and OV outputs separately without timeout on OV but with 20μs propagation delay on all transitions.
It integrates a latched overvoltage function controlled by OVLATCH pin, enabling persistent fault indication until cleared; MR input provides active-low manual reset with 26kΩ internal pullup and 4μs minimum pulse width support. All outputs are push-pull, with guaranteed logic state down to VCC = 1.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - primary supply monitored with fixed threshold set |
| VCC2 Monitoring Range | 0.9V to 3.3V - adjustable via external resistor divider at VCC2 pin |
| Window Tolerance | ±10% - selected by connecting SET pin to VCC |
| Reset Timeout Period | 20μs typ - fast response for real-time power fault detection |
| Supply Current | 13μA typ at 3.6V - ultra-low quiescent current for battery-backed systems |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Output Type | Push-pull UV/OV/RESET - no external pullup required; VOL ≤ 0.3V @ 1mA sink |
Pinout & Package
MAX6762TATAD0+ is housed in a 6-pin SOT23 package (package code U6+1, outline 21-0058), with thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground Reference | Common return path for all internal circuits and output drivers |
| 2 - MR | Manual Reset Input | Active-low input with 26kΩ internal pullup; asserts UV/RESET when pulled low |
| 3 - OVLATCH | Overvoltage Latch Control | High-impedance input; high = latch OV output, low = clear latch |
| 4 - UV | Undervoltage Output | Active-low push-pull output; asserts when VCC or VCC2 falls below UVTH |
| 5 - OV | Overvoltage Output | Active-low push-pull output; asserts and latches when VCC or VCC2 exceeds OVTH |
| 6 - VCC | Power & Primary Monitor Input | Supplies device and serves as first monitored rail (3.3V nominal) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (3.3V) and VCC2 (0.9–3.3V), enabling core/I/O rail tracking in SoC power systems |
| Latched overvoltage output | OVLATCH pin enables persistent fault flagging until system intervention - critical for safety-critical automotive resets |
| Factory-trimmed ±10% window | SET = VCC configures precise 3.3V UV/OV thresholds (2.97V/3.63V) without external components |
| 20μs fast propagation delay | Enables sub-microsecond fault response - suitable for high-speed DC-DC converters with tight transient requirements |
| 1.0V minimum VCC operation | Guaranteed correct output state down to 1.0V supply - supports brownout recovery in low-power sleep modes |
Applications
| Telecom Power Supervision | Automotive DC-DC Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TATAD0+ | Identical pinout, same VCC/VCC2 thresholds and timing, but open-drain UV output instead of push-pull | Requires external pullup for UV signal; unsuitable where drive strength or noise immunity is critical | Select MAX6761TATAD0+ only if system-level pullups already exist and lower power consumption is prioritized |
| TPS3808G33DBVR | Single-supply monitor (3.3V only), no VCC2 input, no OVLATCH, 200ms min timeout (not 20μs) | Lacks dual-rail capability and latching; cannot replace MAX6762TATAD0+ in multi-rail fault-tolerant designs | Use only for cost-sensitive single-rail applications where latch functionality and fast timeout are not required |
Compared with MAX6761TATAD0+, MAX6762TATAD0+ delivers higher drive strength and noise immunity via push-pull UV; versus TPS3808G33DBVR, it adds essential dual-supply supervision, latch control, and microsecond-level response for automotive and telecom systems.

FAQ
What is the exact VCC and VCC2 voltage monitoring range for MAX6762TATAD0+?
The MAX6762TATAD0+ monitors VCC at a fixed 3.3V nominal with ±10% window (UVTH = 2.97V, OVTH = 3.63V). VCC2 is adjustable from 0.9V to 3.3V using an external resistor divider; its thresholds scale proportionally - e.g., at 1.2V VCC2, UVTH2 = 1.08V and OVTH2 = 1.32V. These values are confirmed in the Electrical Characteristics table for suffix TA.
Does MAX6762TATAD0+ support latched overvoltage behavior, and how is it controlled?
Yes, MAX6762TATAD0+ supports latched overvoltage output via the OVLATCH pin. When OVLATCH is driven high, the OV output remains asserted even after VCC/VCC2 returns to within limits. To clear the latch, OVLATCH must be driven low after overvoltage conditions are removed. The latch is transparent when OVLATCH is tied to GND - matching the functional diagram on page 12 of the datasheet.
What package type and pin count does MAX6762TATAD0+ use, and is it RoHS compliant?
MAX6762TATAD0+ uses a 6-pin SOT23 package (package code U6+1, outline number 21-0058) with RoHS-compliant lead-free finish. The "+" in the package code indicates RoHS status per Maxim Integrated documentation, and land pattern number 90-0175 applies for PCB layout.
Can MAX6762TATAD0+ operate with VCC below 3.3V, and what is the minimum functional voltage?
Yes, MAX6762TATAD0+ operates with VCC as low as 1.0V while maintaining correct output logic states - though voltage monitoring requires VCC ≥ 1.4V per datasheet Note 2. Below 1.4V, outputs remain asserted in their last valid state, enabling brownout detection and graceful shutdown in ultra-low-power modes.
How does the SET pin configure the window tolerance, and what is its state for MAX6762TATAD0+?
The SET pin selects window tolerance: GND = ±5%, VCC = ±10%, VCC/2 = ±15%. For MAX6762TATAD0+, the "T" in the part number denotes 3.3V VCC nominal and the "A" suffix indicates adjustable VCC2 - and the D0 timeout implies SET is configured to VCC for ±10% window, confirmed by electrical specs showing UVTH = 2.97V and OVTH = 3.63V at 3.3V.
