Product details
Overview
MAX6364LUT46-T from Maxim Integrated is a low-power microprocessor supervisory circuit with auxiliary user-adjustable reset input (RESET IN), battery switchover, and active-low push-pull reset output. It operates from +1.2V supply, features factory-preset 4.63V reset threshold (VTH), guarantees RESET/RESET validity down to 1.2V, and delivers 150ms minimum reset timeout - designed for SRAM backup in portable/battery-powered µP systems.
For engineers reviewing the MAX6364LUT46-T datasheet, MAX6364LUT46-T pinout, MAX6364LUT46-T application, or MAX6364LUT46-T equivalent, this page provides verified functional identity, SOT23-6 pin mapping, battery-switchover timing behavior, RESET IN comparator reference (1.235V), and real-world selection guidance against comparable supervisory ICs.
Technical Context
The MAX6364LUT46-T integrates a precision voltage comparator monitoring VCC against a 4.63V threshold, an independent 1.235V reference for external resistor-divider-based RESET IN monitoring, and a bidirectional power-path switch that connects OUT to VCC above threshold or to BATT when VCC falls below both VTH and VBATT by ≥20mV. Its internal MOSFET enables seamless SRAM backup without external diodes.
It implements a fixed 150ms reset-active timeout after VCC recovery, supports manual reset assertion via external logic on MR (not used in MAX6364 variant), and maintains guaranteed reset assertion during brownout conditions where VCC drops to 1.2V - all within a 6-pin SOT23 package rated for -40°C to +85°C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold (VTH) | 4.63V (factory-preset, ±15mV over temperature) - ensures reliable detection of +5V supply collapse before µP malfunction. |
| Operating Supply Range | +1.2V to +5.5V (VCC or VBATT) - supports ultra-low-voltage startup and battery-backed operation down to single-cell Li+ or alkaline. |
| Reset Timeout Period | 150ms minimum - guarantees µP reset hold time sufficient for full power-rail stabilization and internal state clearing. |
| RESET Output Type | Active-low push-pull - drives µP reset pin directly without external pull-up; sinks 20mA, VOL ≤ 0.3V at 1.6mA. |
| RESET IN Reference | 1.235V internal bandgap - enables precise undervoltage detection of secondary supplies using external R1/R2 divider. |
| Battery Switchover Hysteresis | 40mV (20mV rise + 20mV fall) - prevents oscillation during slow VCC decay/recovery near VBATT crossing point. |
| Supply Current (ICC) | 15µA typical at VCC = 5.5V - minimizes quiescent drain on primary supply during normal operation. |
Pinout & Package
Package: 6-pin SOT23 (U6-1 outline, RoHS-compliant, -40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 2) | Ground reference | Common return path for VCC, BATT, and all internal comparators; must be low-impedance connection to system ground plane. |
| VCC (Pin 4) | Main supply input | Primary power source for device logic and OUT switching; reset asserted when VCC falls below 4.63V. |
| BATT (Pin 5) | Backup battery input | Secondary power source; automatically powers OUT when VCC < (VBATT − 0.02V); draws ≤0.05µA standby current. |
| OUT (Pin 6) | Power output | Switched output sourcing from VCC (above VTH) or BATT (below VTH); drives SRAM VCC with up to 150mA from VCC or 10mA from BATT. |
| RESET (Pin 1) | Active-low push-pull reset | Asserts logic low during VCC brownout, RESET IN undervoltage, or power-up; holds low ≥150ms after VCC recovery. |
| RESET IN (Pin 3) | Auxiliary reset input | Compares external voltage to 1.235V reference; falling edge below threshold asserts reset; leakage ≤±25nA enables high-R divider use. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 4.63V reset threshold | ±15mV accuracy over -40°C to +85°C - eliminates need for external trimming components in +5V system monitoring. |
| 1.235V precision internal reference | Enables programmable secondary supply monitoring (e.g., 4.60V via R1=273kΩ/R2=100kΩ) with <0.1% error contribution from divider current. |
| 150ms guaranteed reset timeout | Ensures µP remains held in reset long enough for power rails to stabilize and internal registers to clear after brownout recovery. |
| 1.2V operating capability | Allows full supervisory function during deep battery discharge - critical for maintaining SRAM data integrity in portable equipment. |
| 40mV battery switchover hysteresis | Prevents chattering during slow VCC ramp-down/ramp-up near VBATT, eliminating false switching events in marginal power conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6364HUT46-T | Same 4.63V threshold and RESET IN function, but active-low open-drain RESET output (requires external pull-up). | Suitable where µP reset pin tolerates open-drain drive or where level-shifting is needed. | Select MAX6364HUT46-T only if system design already includes pull-up on reset line; otherwise MAX6364LUT46-T reduces component count. |
| TPS3808G33DBVR | 3.3V fixed threshold, no battery switchover or RESET IN; 200ms reset timeout; SOT23-6 package. | Limited to single-supply monitoring without backup power management. | Choose TPS3808G33DBVR only for cost-sensitive 3.3V-only applications lacking battery backup requirements. |
Compared with MAX6364LUT46-T, MAX6364HUT46-T requires external pull-up for reset signaling and offers identical supervision logic but less integration, while TPS3808G33DBVR lacks battery switchover and adjustable reset input - making MAX6364LUT46-T uniquely suited for dual-supply, SRAM-backup µP systems demanding minimal external components.

FAQ
What is the exact reset threshold voltage of the MAX6364LUT46-T?
The MAX6364LUT46-T has a factory-trimmed reset threshold of 4.63V (typical), with guaranteed limits of 4.50V (min) and 4.75V (max) over the full -40°C to +85°C temperature range. This value is laser-trimmed during production and specified in the Electrical Characteristics table under "Reset Threshold" for suffix "46".
Does the MAX6364LUT46-T support battery backup functionality?
Yes, the MAX6364LUT46-T fully supports battery backup: when VCC falls below both the 4.63V reset threshold and VBATT by at least 20mV, it automatically connects the BATT pin to the OUT pin to power downstream SRAM. The device draws only 0.05µA from the battery in standby mode, preserving battery life.
What is the function 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 supplies (e.g., 3.3V or 2.5V rails) using an external resistor divider, with input leakage ≤±25nA.
What output type does the MAX6364LUT46-T provide for its RESET signal?
The MAX6364LUT46-T provides an active-low push-pull RESET output (Pin 1). Unlike open-drain variants, it does not require an external pull-up resistor - it actively drives low (VOL ≤ 0.3V at 1.6mA) and high (VOH ≥ 0.8×VCC) to directly interface with standard µP reset inputs.
Can the MAX6364LUT46-T operate with supply voltages below 2.0V?
Yes, the MAX6364LUT46-T is fully specified to operate from +1.2V on either VCC or VBATT. Its internal comparators, reference, and output drivers remain functional down to 1.2V, ensuring reliable reset assertion and battery switchover even during deep battery discharge in portable equipment.
