Product details
Overview
MAX6364HUT26 from Maxim Integrated is a low-power microprocessor supervisory circuit with auxiliary adjustable reset input, battery switchover, and active-high push-pull reset output. It operates from +1.2V supply, features 2.63V factory-set reset threshold, guarantees RESET assertion down to 1.2V, provides 150ms minimum reset timeout, and supports SRAM backup power switching in brownout conditions.
For engineers reviewing the MAX6364HUT26 datasheet, MAX6364HUT26 pinout, MAX6364HUT26 application, or MAX6364HUT26 equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in battery-backed µP systems, and validated alternative options for power-monitoring and reset control design.
Technical Context
The MAX6364HUT26 integrates a precision 1.235V internal reference for its RESET IN comparator, enabling external undervoltage detection independent of VCC. Its battery switchover logic requires both VCC < VTH and VCC < VBATT − 20mV before connecting BATT to OUT, with 40mV hysteresis to prevent oscillation during slow VCC decay.
RESET output remains high while VCC is below 2.63V and for ≥150ms after VCC rises above threshold; it also asserts when RESET IN falls below 1.235V. The device draws only 11µA at VCC = 2.8V and maintains guaranteed operation across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63V (factory preset; precise monitoring of +2.5V systems) |
| Operating Supply | +1.2V to +5.5V (supports ultra-low-voltage µP rails and battery backup) |
| Reset Timeout | 150ms minimum (ensures reliable µP initialization after power recovery) |
| Supply Current | 11µA at VCC = 2.8V (enables multi-year battery life in backup mode) |
| RESET IN Threshold | 1.235V ±5mV (stable reference for external power-rail monitoring) |
| Output Type | Active-high push-pull RESET (drives µP reset pin directly without pull-up) |
| Temperature Range | −40°C to +85°C (qualified for industrial embedded environments) |
Pinout & Package
MAX6364HUT26 uses a 6-pin SOT23-6 package with exposed pad (not electrically connected), footprint-compatible with JEDEC MO-178AA. Pin 1 is RESET (active-high push-pull), Pin 2 is GND, Pin 3 is RESET IN, Pin 4 is OUT, Pin 5 is BATT, Pin 6 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Active-high reset output | Drives µP reset pin high during fault; no external pull-up required |
| 2 - GND | Ground reference | Common return for VCC, BATT, and internal comparators |
| 3 - RESET IN | Auxiliary reset input | Comparator input referenced to 1.235V; asserts reset if voltage < 1.235V |
| 4 - OUT | Power output | Switches between VCC and BATT; powers SRAM during brownout |
| 5 - BATT | Backup battery input | Connects to Li+ or coin cell; sources current only when VCC < VTH and VCC < VBATT − 20mV |
| 6 - VCC | Main supply input | Primary power source; reset asserted when falling below 2.63V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6364HUT29 | 2.93V reset threshold; identical pinout, timing, and features | Suitable for +3.0V or +3.3V systems requiring higher trip point | Select when main supply nominal is ≥3.0V and 2.63V threshold causes premature reset |
| TPS3808G33DBVR | 3.08V fixed threshold; open-drain RESET; 1.8V–6.0V supply range; no RESET IN | Lacks auxiliary reset input and battery switchover; requires external diode-OR for backup | Choose when only basic reset supervision is needed and RESET IN functionality is unused |
Compared with MAX6364HUT26, MAX6364HUT29 offers higher reset threshold for tighter margin on 3.0V rails, while TPS3808G33DBVR trades RESET IN and battery control for wider supply range and lower quiescent current (1.1µA), but requires redesign for backup power path.

FAQ
What is the exact reset threshold voltage of the MAX6364HUT26?
The MAX6364HUT26 has a factory-trimmed reset threshold of 2.63V, with ±1.5% tolerance over −40°C to +85°C. This value is specified in Table 1 of the datasheet under suffix "26" and applies to the VCC supply falling condition. The threshold is internally generated and does not require external components.
Does the MAX6364HUT26 support battery switchover, and how does it behave?
Yes, the MAX6364HUT26 supports automatic battery switchover. When VCC falls below 2.63V and drops at least 20mV below VBATT, the internal MOSFET connects BATT to OUT. Switchover includes 40mV hysteresis to prevent oscillation. The device draws less than 1µA from the battery in backup mode (VBATT = 2.8V, VCC = 0), preserving battery life.
What is the function of the RESET IN pin on the MAX6364HUT26?
The RESET IN pin on the MAX6364HUT26 is an auxiliary reset input compared to an internal 1.235V reference. When voltage at RESET IN falls below 1.235V, the device asserts RESET regardless of VCC level. This enables monitoring of secondary rails (e.g., RTC, analog sensors) and provides fail-safe reset independent of main supply status.
What output type does the MAX6364HUT26 provide, and how is it used?
The MAX6364HUT26 provides an active-high push-pull RESET output (denoted by "H" in the part number). It drives the reset line high during fault conditions and releases it low upon recovery. No external pull-up resistor is needed, simplifying PCB layout and ensuring robust drive strength up to 1mA sink/source at VCC ≥ 1.2V.
Can the MAX6364HUT26 operate with a 1.2V supply, and what are the implications?
Yes, the MAX6364HUT26 operates down to +1.2V on VCC or VBATT, with guaranteed RESET/RESET validity at that level. At 1.2V, supply current is ~15µA, and OUT can deliver up to 25mA. However, battery switchover requires VBATT ≥ VCC + 20mV, so effective backup operation begins only when VBATT exceeds 1.22V - compatible with single-cell Li+ or NiMH configurations.
