Product details
Overview
MAX6364LUT31-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 3.08V reset threshold (±1.5% over temperature), guarantees RESET/RESET validity down to 1.2V, and delivers 150ms minimum reset timeout. It is used in portable/battery-powered equipment for SRAM backup power control and secondary supply monitoring.
For engineers reviewing the MAX6364LUT31-T datasheet, MAX6364LUT31-T pinout, MAX6364LUT31-T application, or MAX6364LUT31-T equivalent, key selection considerations include its 3.08V precision reset threshold, 1.235V internal reference for external resistor-programmable RESET IN, SOT23-6 package footprint, battery switchover hysteresis (40mV), and guaranteed operation at VCC/VBATT ≥1.2V - all critical for brownout resilience and dual-supply monitoring in space-constrained embedded systems.
Technical Context
The MAX6364LUT31-T integrates a precision voltage comparator for primary VCC monitoring (3.08V threshold), a dedicated 1.235V reference with ±0.5% accuracy for external resistor-divider-based RESET IN, and a battery switchover MOSFET with 40mV hysteresis between VCC and VBATT. Its push-pull RESET output drives µP reset inputs directly without external pull-up.
It supports dual-supply supervision: VCC powers OUT during normal operation; when VCC falls below 3.08V and VBATT exceeds VCC by >20mV, the internal MOSFET connects BATT to OUT. RESET IN monitors secondary supplies (e.g., analog rails) via external resistors, with propagation delay <100µs (typ) from RESET IN falling edge to reset assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08V ±1.5% (factory preset; ensures reliable detection of 3.3V rail brownout) |
| RESET IN Reference | 1.235V ±0.5% (enables accurate external resistor programming of secondary supply reset points) |
| Supply Voltage Range | +1.2V to +5.5V (supports ultra-low-voltage operation and full compatibility with 5V/3.3V/2.5V systems) |
| Reset Timeout Period | 150ms minimum (guarantees µP reset hold time sufficient for stable power-up sequencing) |
| Battery Switchover Hysteresis | 40mV (prevents oscillation during slow VCC decay near VBATT) |
| Operating Temperature | -40°C to +85°C (qualified for industrial ambient environments) |
| Supply Current (VCC) | 11µA typ at 2.8V (minimizes quiescent drain on main supply in always-on monitoring) |
Pinout & Package
Package: 6-pin SOT23 (U6-1 outline, 2.9mm × 1.6mm × 1.1mm height), RoHS-compliant lead-free (-T suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: RESET | Active-low push-pull reset output | Drives µP reset pin directly; no external pull-up required; sinks 20mA max |
| 2: GND | Ground reference | Common return for VCC, VBATT, and all internal circuits; must be low-impedance |
| 3: RESET IN | Auxiliary reset input | Compares external voltage to 1.235V reference; asserts reset if input <1.235V |
| 4: VCC | Main supply input | Primary power source; reset asserted when VCC <3.08V; powers OUT during normal operation |
| 5: OUT | Power output | Supplies SRAM or other backup loads; sourced from VCC or BATT depending on switchover state |
| 6: BATT | Backup battery input | Connects to Li+ or coin cell; activates OUT path when VCC fails and VBATT > VCC +20mV |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6364PUT31-T | Same 3.08V threshold and RESET IN function, but active-low open-drain RESET output requiring external pull-up | Suitable where µP reset pin has internal pull-up or board-level pull-up already exists | Select when system-level pull-up is available and lower standby current (30µA vs 11µA) is not critical |
| TPS3808G30DBVR | 3.0V fixed threshold, no RESET IN input, open-drain RESET, higher 16µA ICC (typ) | Lacks auxiliary reset monitoring; limited to single-rail supervision only | Choose only if secondary supply monitoring is unnecessary and SOT23-6 footprint compatibility is required |
Compared with MAX6364LUT31-T, MAX6364PUT31-T trades push-pull drive simplicity for slightly higher supply current and external pull-up dependency, while TPS3808G30DBVR omits RESET IN entirely - making MAX6364LUT31-T uniquely suited for dual-supply monitoring in compact battery-backed systems.

FAQ
What is the exact reset threshold voltage of the MAX6364LUT31-T?
The MAX6364LUT31-T has a factory-preset reset threshold of 3.08V, with guaranteed tolerance of ±1.5% over the full -40°C to +85°C operating temperature range. This value is laser-trimmed during production and does not require external components. The "31" suffix in the part number explicitly denotes the 3.08V threshold variant per Maxim's ordering guide.
How does the RESET IN pin function on the MAX6364LUT31-T?
The RESET IN pin on the MAX6364LUT31-T compares an externally applied voltage to an internal 1.235V reference. When the voltage at RESET IN falls below 1.235V, the device asserts reset. This enables monitoring of secondary power supplies (e.g., analog rails) using a simple resistor divider. The MAX6364LUT31-T datasheet provides the formula VRTH = VREF × (1 + R1/R2) for setting the trip point.
What is the purpose of the BATT pin on the MAX6364LUT31-T?
The BATT pin on the MAX6364LUT31-T accepts a backup battery (e.g., 3.6V Li+ cell) and enables automatic switchover to battery power when the main VCC supply drops below the 3.08V reset threshold and VBATT exceeds VCC by at least 20mV. An internal MOSFET connects BATT to the OUT pin, providing uninterrupted power to SRAM or other critical loads during main supply failure.
Does the MAX6364LUT31-T require external components to operate?
The MAX6364LUT31-T requires no external components for basic supervision: its 3.08V threshold is factory-set, RESET is push-pull, and battery switchover is self-contained. However, a 0.1µF bypass capacitor on VCC is recommended for transient immunity, and external resistors are needed only if using the RESET IN function to monitor secondary supplies.
What is the guaranteed minimum reset timeout period for the MAX6364LUT31-T?
The MAX6364LUT31-T guarantees a minimum reset timeout period of 150ms after VCC rises above the 3.08V threshold, after RESET IN recovers, or after manual reset release. This duration is specified over temperature and ensures sufficient hold time for microprocessor initialization and peripheral stabilization before code execution resumes.
