Product details
Overview
MAX6356TZUT+ from Maxim Integrated is a triple-voltage microprocessor supervisory circuit with precision dual-supply monitoring (VCC1 = 3.08V, VCC2 = 2.32V), an adjustable third-voltage input (RSTIN = 1.22V threshold), active-low push-pull reset referenced to VCC1, and debounced manual-reset input. It operates over -40°C to +85°C in 6-pin SOT23 and ensures system reliability in multivoltage embedded controllers.
For engineers reviewing the MAX6356TZUT+ datasheet, MAX6356TZUT+ pinout, MAX6356TZUT+ application, or MAX6356TZUT+ equivalent, key selection concerns include its triple-supply monitoring capability, guaranteed RESET validity down to VCC1 ≥ 1.0V or VCC2 ≥ 1.0V, 100ms minimum reset timeout, 20µA supply current, and compatibility with 1.8V–5.5V supply rails.
Technical Context
The MAX6356TZUT+ integrates two factory-trimmed voltage comparators for VCC1 and VCC2 monitoring plus a dedicated RSTIN comparator with 1.22V internal reference, enabling precise third-rail supervision via external resistive divider. Its reset generator asserts active-low RST when either monitored supply falls below its threshold or RSTIN drops below 1.22V.
It features a debounced TTL/CMOS-compatible MR input with 1µs minimum pulse width and glitch rejection of 100ns, and guarantees valid reset output as long as at least one supply remains ≥1.0V - critical for brownout resilience in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 3.08V ±0.08V (guaranteed over -40°C to +85°C); sets primary reset trigger point for main system rail |
| VCC2 Threshold | 2.32V ±0.07V (guaranteed over -40°C to +85°C); monitors secondary rail such as I/O or analog supply |
| RSTIN Threshold | 1.22V ±0.03V (typical); enables accurate supervision of third voltage (e.g., 1.2V core) using external resistor divider |
| Reset Timeout | 100–280ms; ensures sufficient processor initialization time after power-up or fault recovery |
| Supply Current | 20µA typical; supports ultra-low-power operation in portable and always-on systems |
| Operating Temp | -40°C to +85°C; qualified for industrial and extended-temperature embedded applications |
| RESET Valid Down To | VCC1 ≥ 1.0V or VCC2 ≥ 1.0V; maintains functional reset assertion during deep brownout conditions |
Pinout & Package
MAX6356TZUT+ is housed in a RoHS-compliant 6-pin SOT23 package (U6-1 outline), with 0.95mm pitch, 2.9mm × 1.6mm footprint, and thermal pad not present. Pin 1 is RST (active-low push-pull referenced to VCC1), Pin 2 is GND, Pin 3 is MR, Pin 4 is VCC2, Pin 5 is RSTIN, and Pin 6 is VCC1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low push-pull reset output | Referenced to VCC1; drives low without external pull-up; compatible with 1.8V–5.5V logic interfaces |
| 2 - GND | Ground reference | Common return path for all internal comparators and reset logic; must be low-impedance |
| 3 - MR | Manual-reset input | Debounced active-low input; forces reset when pulled ≤0.8V (for _T/_S/_R versions); no external pull-up required |
| 4 - VCC2 | Secondary supply input | Powers device if > VCC1; monitored at 2.32V threshold; must remain ≤6V and ≥-0.3V |
| 5 - RSTIN | Adjustable undervoltage comparator input | Monitors third rail via internal 1.22V reference; accepts external divider; voltage must not exceed VCC1 |
| 6 - VCC1 | Primary supply input | Powers device if > VCC2; monitored at 3.08V threshold; defines RST output reference and powers RSTIN circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Triple-supply monitoring | Simultaneously supervises VCC1 (3.08V), VCC2 (2.32V), and third rail via RSTIN (1.22V ref), eliminating need for discrete supervisors in multirail systems |
| Guaranteed reset validity to 1.0V | Ensures reliable reset assertion even during severe brownout - critical for safe shutdown in battery-backed or energy-harvesting designs |
| No external components required | Factory-trimmed thresholds and integrated glitch filtering remove need for external resistors, capacitors, or RC networks |
| 20µA ultra-low quiescent current | Enables multi-year operation on coin-cell batteries in portable instrumentation and IoT edge nodes |
| 100ns MR glitch rejection | Rejects noise-induced false resets on manual-reset line, improving field reliability in electrically noisy environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6355TZUT+ | Same pinout and triple-supply architecture, but features open-drain RST output instead of push-pull | Requires external pull-up resistor; better suited for wired-OR reset buses or level-shifting interfaces | Select MAX6355TZUT+ only if system requires open-drain reset signaling or shared reset bus topology |
| TPS3808G33DBVR | Dual-supply monitor (3.3V/1.8V only); no RSTIN input; fixed 3.3V VDD threshold, 1.8V VDD2 threshold; 350ms reset timeout | Lacks third-rail monitoring capability; longer reset timeout limits use in fast-booting processors | Choose TPS3808G33DBVR only for dual-rail systems where RSTIN functionality is unnecessary and longer reset hold is acceptable |
Compared with MAX6356TZUT+, MAX6355TZUT+ offers identical monitoring precision and temperature range but requires external pull-up due to open-drain RST, while TPS3808G33DBVR omits RSTIN entirely and cannot supervise a third voltage - making MAX6356TZUT+ the sole option for true triple-rail deterministic reset in space-constrained SOT23 designs.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6356TZUT+?
The MAX6356TZUT+ has a factory-set VCC1 threshold of 3.08V (±0.08V over -40°C to +85°C) and VCC2 threshold of 2.32V (±0.07V over temperature). These values are laser-trimmed during production and documented in the Voltage Threshold Levels table of the MAX6356TZUT+ datasheet - no external calibration is required.
Does the MAX6356TZUT+ support monitoring a third voltage, and how is it implemented?
Yes, the MAX6356TZUT+ supports third-voltage monitoring via its RSTIN pin, which features an internal 1.22V ±0.03V comparator reference. To supervise voltages above 1.22V (e.g., 3.3V or 5V), connect a resistive divider between the target rail and RSTIN, ensuring VRSTIN never exceeds VCC1. This enables full triple-rail supervision in a single 6-pin SOT23 package.
What is the function of the MR pin on the MAX6356TZUT+, and what are its voltage thresholds?
The MR pin on the MAX6356TZUT+ is a debounced active-low manual-reset input. For the TZ suffix (3.08V/2.32V thresholds), MR asserts reset when pulled ≤0.8V (VIL) and releases reset when rising above 2.3V (VIH), with 100ns glitch rejection and 1µs minimum pulse width. No external pull-up is needed - internal pullup is absent, so external biasing is required if left unused.
Can the MAX6356TZUT+ operate with supply voltages below 2.0V, and what is the minimum valid VCC?
Yes, the MAX6356TZUT+ guarantees functional operation with VCC1 or VCC2 as low as +1.2V over temperature, and its RESET output remains valid as long as either supply stays ≥+1.0V. This enables use in ultra-low-voltage systems such as energy-harvesting nodes or deep-brownout recovery circuits where other supervisors fail.
Is the MAX6356TZUT+ pin-compatible with other devices in the MAX6351–MAX6360 family?
The MAX6356TZUT+ shares the same 6-pin SOT23 (U6-1) package and pinout as MAX6351, MAX6355, MAX6357–MAX6360, but differs functionally: it provides push-pull RST referenced to VCC1 (unlike MAX6355's open-drain or MAX6357's VCC2-referenced RST). Pin compatibility exists physically, but electrical behavior and feature set require verification per application.
