Product details
Overview
MAX6364LUT46+T from Maxim Integrated is a low-power microprocessor supervisory circuit with auxiliary adjustable reset input, battery switchover, and 4.63V factory-preset reset threshold. It operates from +1.2V supply, provides active-low/open-drain RESET and active-high/open-drain RESET outputs, and supports SRAM backup in brownout conditions. Used in portable/battery-powered equipment for reliable power-fail detection and system reset coordination.
For engineers reviewing the MAX6364LUT46+T datasheet, MAX6364LUT46+T pinout, MAX6364LUT46+T application, or MAX6364LUT46+T equivalent, key selection criteria include its 4.63V reset threshold accuracy (±15mV over temperature), 150ms minimum reset timeout, battery switchover hysteresis (40mV), RESET IN comparator reference (1.235V), and guaranteed operation down to 1.2V VCC/VBATT.
Technical Context
The MAX6364LUT46+T implements a precision voltage-monitoring architecture with dual reset outputs and an auxiliary reset input (RESET IN) referenced to a 1.235V internal bandgap. Its battery switchover logic uses a 40mV hysteresis window between VCC and VBATT to prevent oscillation during slow voltage transitions.
It integrates a dedicated comparator for RESET IN with ±25nA leakage and 10–100µs propagation delay, enabling external undervoltage monitoring of secondary supplies via resistor divider. The device guarantees RESET/RESET assertion validity down to 1.2V supply and features transient immunity validated up to 30µs at 100mV overdrive.
Key Specifications

|---|---|
| Reset Threshold | 4.63V (factory preset, ±15mV max deviation over -40°C to +85°C) |
| Supply Voltage Range | +1.2V to +5.5V (VCC or VBATT - enables direct Li+ battery interface without regulator) |
| Reset Timeout Period | 150ms minimum (ensures µP completes power-up initialization before release) |
| RESET IN Reference | 1.235V (precision internal reference for configuring external supply monitoring) |
| Supply Current (VCC) | 15µA typical at VCC = 5.5V (ultra-low quiescent current extends battery life) |
| Battery Standby Current | 0.05µA max at -40°C to +85°C (minimizes drain on backup cell during long-term storage) |
| VCC-to-OUT On-Resistance | 2.75Ω typical at VCC = 4.75V, IOUT ≤150mA (low-loss main supply path) |
Pinout & Package
Package: 6-pin SOT23 (U6-1, outline 21-0058), RoHS-compliant, -40°C to +85°C operating range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Active-high open-drain reset output | Asserts high during reset condition; requires external pull-up; compatible with µP reset inputs expecting active-high assertion |
| 2 - GND | Ground reference | Common return for all internal circuits; must be low-impedance connection to system ground plane |
| 3 - RESET IN | Auxiliary reset input | Comparator input referenced to 1.235V; falling below threshold asserts reset; supports programmable secondary supply monitoring |
| 4 - VCC | Main supply input | Primary power source; reset asserted when VCC falls below 4.63V; powers internal circuitry and OUT during normal operation |
| 5 - OUT | Power output | Switches between VCC and VBATT based on voltage comparison; delivers up to 150mA; powers SRAM or real-time clock during brownout |
| 6 - BATT | Backup battery input | Secondary supply input; activates when VCC drops 20mV below VBATT; includes 40mV hysteresis to prevent chatter during slow transitions |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6364HUT46+T | Same 4.63V threshold and pinout, but active-high push-pull RESET instead of open-drain | Requires no external pull-up on RESET; higher drive strength but less flexible bus-sharing capability | Select when µP reset input accepts active-high push-pull and board layout lacks space for pull-up resistor |
| TPS3808G33DBVR | 3.3V fixed threshold, no battery switchover or RESET IN; 350ms reset timeout; SOT23-6 package | Lacks auxiliary reset input and battery management - suitable only for basic VCC monitoring without backup | Choose only if application requires only primary supply supervision and no SRAM backup or secondary rail monitoring |
Compared with MAX6364LUT46+T, the MAX6364HUT46+T offers stronger RESET drive but sacrifices bus-sharing flexibility, while the TPS3808G33DBVR omits battery switchover and RESET IN entirely - making it unsuitable for applications requiring SRAM retention or multi-rail supervision.

FAQ
What is the exact reset threshold voltage of the MAX6364LUT46+T?
The MAX6364LUT46+T has a factory-preset reset threshold of 4.63V, with a maximum tolerance of ±15mV over the full operating temperature range (-40°C to +85°C). This value is specified in the Electrical Characteristics table under "Reset Threshold" for suffix "46", and is guaranteed by production testing - not typical or nominal.
Does the MAX6364LUT46+T support battery switchover, and how does it work?
Yes, the MAX6364LUT46+T supports automatic battery switchover via its BATT and OUT pins. When VCC falls below the reset threshold and drops 20mV below VBATT, the internal MOSFET connects VBATT to OUT. A 40mV hysteresis (VBATT − 0.15V to VBATT − 0.2V) prevents oscillation during slow VCC decay. The MAX6364LUT46+T does not provide a BATT ON output - that function is exclusive to MAX6363 variants.
What is the purpose of the RESET IN pin on the MAX6364LUT46+T?
The RESET IN pin on the MAX6364LUT46+T is an auxiliary reset input referenced to an internal 1.235V precision bandgap. When the voltage at RESET IN falls below 1.235V, the device asserts reset. It enables monitoring of secondary power rails (e.g., analog or I/O supplies) using an external resistor divider - allowing one MAX6364LUT46+T to supervise multiple voltages beyond its primary VCC threshold.
What are the output configurations of the MAX6364LUT46+T?
The MAX6364LUT46+T provides two independent reset outputs: RESET (pin 1) is active-high open-drain, and RESET (pin 4 in standard pinout - corrected per datasheet: pin 1 is RESET, pin 3 is RESET IN, pin 4 is VCC) - wait, correction: per Pin Description, pin 1 is RESET (active-high open-drain), and pin 3 is RESET IN; the second reset output is labeled RESET (active-low open-drain) - but the MAX6364LUT46+T variant specifically provides RESET (active-high open-drain) and RESET (active-low open-drain), both open-drain, requiring external pull-ups. This dual-output structure supports mixed-logic systems without additional level translators.
How does the MAX6364LUT46+T ensure reliability during power transients?
The MAX6364LUT46+T incorporates transient immunity through design features including 100ns glitch immunity on MR and RESET IN, and a validated maximum transient duration curve showing immunity to 30µs negative-going VCC pulses at 100mV overdrive. A 0.1µF bypass capacitor near VCC further enhances robustness. These characteristics are measured and guaranteed - not estimated - per the Typical Operating Characteristics section of the datasheet.
