Product details
Overview
MAX6364PUT26 from Maxim Integrated is a low-power microprocessor supervisory circuit with battery switchover, auxiliary reset input, and factory-preset 2.63V reset threshold. It monitors +2.5V/+3.0V/+3.3V/+5.0V supplies, asserts reset during brownout or power failure, and switches SRAM supply to backup battery when VCC falls below threshold. Designed for portable/battery-powered equipment requiring reliable power monitoring and data retention.
For engineers reviewing the MAX6364PUT26 datasheet, MAX6364PUT26 pinout, MAX6364PUT26 application, or MAX6364PUT26 equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in critical µP systems, and validated alternative options - all grounded in Maxim's official specifications and ordering documentation.
Technical Context
The MAX6364PUT26 integrates a precision voltage comparator (1.235V internal reference) for its RESET IN input, enabling external undervoltage detection independent of VCC monitoring. Its battery switchover logic requires both VCC < VTH and VCC < VBATT − 0.15V to engage, with 40mV hysteresis preventing oscillation during slow VCC decay.
It features an active-low push-pull RESET output with guaranteed assertion down to 1.2V VCC or VBATT, 150ms minimum timeout, and glitch immunity up to 100ns. The OUT pin sources up to 150mA from VCC or VBATT, with on-resistance as low as 2.25Ω at VBATT = 2.8V and TA = +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63V (factory preset, ±1.5% accuracy over -40°C to +85°C) |
| RESET IN Threshold | 1.235V (internal reference, used for secondary undervoltage detection) |
| Supply Voltage Range | +1.2V to +5.5V (supports operation during deep brownout or battery-only mode) |
| Reset Timeout Period | 150ms minimum (ensures µP completes full reset sequence before release) |
| Supply Current (VCC) | 11µA typical at VCC = 2.8V (enables multi-year battery life in backup mode) |
| Battery Standby Current | 0.02µA typical at TA = +25°C (minimizes battery drain when VCC is active) |
| OUT On-Resistance | 2.25Ω max at VBATT = 2.8V (limits voltage drop under 25mA SRAM load) |
Pinout & Package
MAX6364PUT26 is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), optimized for space-constrained portable designs. Pinout matches the MAX6364 family and is fully compatible with standard SOT23-6 footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common return path for VCC, VBATT, and output stages; must be low-impedance for noise immunity |
| VCC | Main supply input | Primary power source; reset asserted when voltage falls below 2.63V |
| RESET IN | Auxiliary reset trigger | Asserts reset when voltage drops below 1.235V; enables secondary power-rail monitoring |
| BATT | Backup battery input | Connects to Li+ or coin cell; powers OUT when VCC fails and meets switchover conditions |
| OUT | Switched output supply | Delivers regulated power to SRAM; sourced from VCC or BATT depending on voltage comparison |
| RESET | Active-low push-pull reset signal | Drives µP reset pin directly; sinks 1.6mA at 0.4V VOL, no external pull-up required |
Key Features
| Feature | Design Value |
|---|---|
| Factory-preset 2.63V reset threshold | Eliminates external resistor divider; ensures accurate +2.5V system monitoring without calibration |
| 1.235V RESET IN comparator | Enables independent monitoring of auxiliary rails (e.g., analog supply, I/O voltage) with fixed reference |
| 150ms reset timeout with temperature stability | Maintains reset assertion across -40°C to +85°C; prevents premature µP release during thermal stress |
| 2.25Ω BATT-to-OUT on-resistance | Supports 25mA SRAM load with <60mV dropout at 2.8V battery, preserving data integrity |
| 11µA VCC supply current at 2.8V | Extends primary supply runtime in always-on monitoring applications without compromising responsiveness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6364HUT26 | Same 2.63V threshold and RESET IN function, but active-high push-pull RESET output | Requires µP with active-high reset input; incompatible with standard active-low reset designs | Select only if host µP reset pin is active-high and PCB layout allows RESET polarity change |
| TPS3808G125DBVR | 1.25V adjustable reset threshold (via external resistor), no battery switchover or RESET IN pin | Lacks BATT/OUT switching and auxiliary reset input; suitable only for single-rail monitoring without backup power | Choose when cost sensitivity outweighs battery backup need and reset threshold must be user-configurable |
Compared with MAX6364PUT26, MAX6364HUT26 offers identical supervision accuracy and battery control but requires redesign of reset signal routing, while TPS3808G125DBVR reduces BOM count for basic VCC monitoring but cannot replace MAX6364PUT26 in SRAM-retention-critical applications.

FAQ
What is the exact reset threshold voltage of the MAX6364PUT26?
The MAX6364PUT26 has a factory-preset reset threshold of 2.63V, with ±1.5% accuracy over the full operating temperature range (-40°C to +85°C). This value is confirmed in Table 1 of the Maxim datasheet and corresponds to the "26" suffix in the part number. The threshold is trimmed during production and does not require external components.
Does the MAX6364PUT26 support battery switchover, and what are the activation conditions?
Yes, the MAX6364PUT26 supports automatic battery switchover to the OUT pin. Switchover activates only when two conditions are met simultaneously: VCC falls below the 2.63V reset threshold AND VCC is at least 0.15V lower than VBATT. This 40mV hysteresis prevents chattering during slow VCC decay and is documented in the Pin Description and Detailed Description sections.
What is the function of the RESET IN pin on the MAX6364PUT26?
The RESET IN pin on the MAX6364PUT26 connects to an internal 1.235V comparator. When the voltage at RESET IN falls below 1.235V, the device asserts the RESET output regardless of VCC status. This enables secondary power-rail monitoring - for example, detecting failure of an analog supply or I/O voltage - and is explicitly defined in the Electrical Characteristics table and Pin Description.
What output type does the MAX6364PUT26 feature, and how is it configured?
The MAX6364PUT26 features an active-low push-pull RESET output, indicated by the "P" in the part number suffix (PUT26). This means the RESET pin actively drives low during reset and high when released, eliminating the need for an external pull-up resistor. Output drive strength is specified as 1.6mA sink at 0.4V VOL, per the Electrical Characteristics table.
Can the MAX6364PUT26 operate with supply voltages below 2.63V?
Yes, the MAX6364PUT26 operates from VCC or VBATT as low as +1.2V, and its RESET output remains valid down to 1.2V - meaning it continues asserting reset even as VCC collapses below the 2.63V threshold. This behavior is guaranteed in the Absolute Maximum Ratings and Electrical Characteristics tables, ensuring robust brownout response.
