Product details
Overview
MAX6354RVUK-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with active-low push-pull reset output referenced to VCC2, precision factory-set thresholds of 2.63V (VCC1) and 1.58V (VCC2), 20µA supply current, and guaranteed RESET validity down to VCC1 ≥ 1V or VCC2 ≥ 1V - used in multivoltage embedded systems to ensure reliable power-on and brownout reset sequencing.
For engineers reviewing the MAX6354RVUK-T datasheet, MAX6354RVUK-T pinout, MAX6354RVUK-T application, or MAX6354RVUK-T equivalent, key selection criteria include dual-supply threshold accuracy, reset output referencing (VCC2), manual-reset debouncing, SOT23-5 package compatibility, and operation across –40°C to +85°C industrial temperature range.
Technical Context
The MAX6354RVUK-T monitors two independent supply rails (VCC1 and VCC2) and asserts its single active-low push-pull RST output when either falls below its respective factory-trimmed threshold (2.63V for VCC1, 1.58V for VCC2). Reset assertion is guaranteed as long as at least one supply remains ≥ 1.0V, enabling robust low-voltage operation during brownout conditions.
It features a debounced TTL/CMOS-compatible manual-reset input (MR), supports no external components for dual-rail supervision, and delivers a minimum 100ms power-on-reset pulse width. Unlike watchdog-equipped variants (e.g., MAX6359/MAX6360), MAX6354RVUK-T lacks WDI functionality and is not part of the watchdog-enabled subgroup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 2.63V ±0.05V (–40°C to +85°C); precise detection of +2.7V nominal rail collapse |
| VCC2 Threshold | 1.58V ±0.03V (–40°C to +85°C); accurate monitoring of +1.6V or +1.8V logic supply |
| Supply Current | 20µA typical; enables ultra-low-power battery-backed or always-on supervision |
| Reset Pulse Width | 100–280ms; ensures sufficient duration for μP initialization and peripheral settling |
| Operating Temp | –40°C to +85°C; qualified for industrial-grade embedded control and instrumentation |
| Reset Output Type | Active-low push-pull referenced to VCC2; drives loads directly without external pull-up |
| Reset Validity | Guaranteed while VCC2 ≥ 1.0V; maintains valid reset state during deep brownout |
Pinout & Package
MAX6354RVUK-T is housed in a 5-pin SOT23 package (U5-1 outline, 21-0057), with 1.6mm × 2.9mm footprint and 0.95mm height - compatible with high-density PCB layouts and reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low reset output | Push-pull driver referenced to VCC2; sinks 1.2mA @ VCC2 ≥ 2.7V, VOH = 0.8×VCC2 |
| 2 - GND | Ground reference | Common return path for internal comparators, MR input, and reset output |
| 3 - MR | Manual-reset input | Debounced active-low input; forces reset when pulled ≤ 0.8V (VCC1 > VTH1) |
| 4 - VCC2 | Secondary supply input | Powers device and sets RST output reference; monitored at 1.58V threshold |
| 5 - VCC1 | Primary supply input | Monitored at 2.63V threshold; powers internal logic but does not reference RST output |
Key Features
| Feature | Design Value |
|---|---|
| Dual-voltage precision monitoring | Simultaneously tracks +2.7V (VCC1) and +1.6V (VCC2) rails with <20ppm/°C tempco |
| Factory-trimmed thresholds | No calibration required; 2.63V/1.58V thresholds guaranteed over full temperature range |
| Low-quiescent-current operation | 20µA max ICC enables multi-year battery life in portable equipment |
| VCC-referenced push-pull RST | RST output swings fully between GND and VCC2 - eliminates need for external pull-up resistor |
| Brownout resilience | RESET remains valid even if VCC2 drops to 1.0V - critical for graceful system shutdown |
Applications
| Computers | Portable/Battery-Powered Equipment |
|---|---|
Use Scenario: Desktop motherboard with separate +2.5V I/O and +1.5V core supplies. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting reset when either rail collapses, ensuring coordinated CPU and chipset reset.

IC Role / Device Role / Timing Role: Supervises dual isolated rails and provides clean reset to ARM Cortex-M4 controller on power-up and fault. Use Value: Eliminates need for discrete comparator + timer circuits - reduces BOM count by 4 components per channel. | Use Scenario: Digital multimeter with segmented LCD, microcontroller, and analog front-end powered from +2.7V and +1.6V supplies. IC Role / Device Role / Timing Role: Ensures display and measurement subsystems initialize only after both supplies stabilize. Use Value: Prevents corrupted readings or display artifacts caused by asynchronous power sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6353RVUK-T | Same thresholds (2.63V/1.58V) but RST output referenced to VCC1 instead of VCC2 | Requires VCC1 as reset reference rail; unsuitable where reset must track VCC2 stability | Select when reset signal must be level-shifted to primary supply domain |
| TPS3808G15DBVR | Single-supply supervisor (1.5V threshold only); no dual-rail monitoring or VCC2-referenced output | Lacks dual-threshold capability - requires additional IC for second rail | Choose only for single-rail systems where cost and space outweigh dual-monitoring need |
Compared with MAX6353RVUK-T, MAX6354RVUK-T provides VCC2-referenced reset essential for systems where secondary supply integrity dictates reset timing; versus TPS3808G15DBVR, it delivers integrated dual-rail supervision without external components or layout overhead.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6354RVUK-T?
The MAX6354RVUK-T has a factory-trimmed VCC1 threshold of 2.63V (±0.05V over –40°C to +85°C) and a VCC2 threshold of 1.58V (±0.03V over the same range). These values are confirmed in the Voltage Threshold Levels table and Electrical Characteristics section of the official datasheet, and correspond to the "RV" suffix in the ordering nomenclature.
Does the MAX6354RVUK-T include a watchdog timer function?
No, the MAX6354RVUK-T does not include a watchdog timer. Watchdog functionality is exclusive to the MAX6358/MAX6359/MAX6360 variants in the family. The MAX6354RVUK-T provides only dual-voltage monitoring, manual reset, and a single VCC2-referenced push-pull reset output - verified by the Selector Guide and Pin Configurations table.
What is the package type and pin count of the MAX6354RVUK-T?
The MAX6354RVUK-T uses a 5-pin SOT23 package (package code U5-1, outline 21-0057), with standard lead spacing and RoHS-compliant construction. This matches the "UK-T" suffix in the part number and is explicitly listed in the Ordering Information table alongside other 5-pin variants like MAX6352 and MAX6353.
How does the reset output of the MAX6354RVUK-T interface with downstream logic?
MAX6354RVUK-T features an active-low push-pull RST output referenced to VCC2, capable of sinking 1.2mA at VCC2 ≥ 2.7V (VOL ≤ 0.3V) and sourcing current up to 350µA (VOH ≥ 0.8×VCC2). This eliminates the need for an external pull-up resistor and ensures direct compatibility with CMOS inputs operating at the VCC2 voltage level.
Is the MAX6354RVUK-T suitable for operation down to 1.0V on either supply rail?
Yes - the MAX6354RVUK-T guarantees valid reset output as long as either VCC1 ≥ 1.0V or VCC2 ≥ 1.0V, per Absolute Maximum Ratings and Electrical Characteristics. This allows continued supervision during deep brownout events, a key differentiator from many competing supervisors that require ≥1.8V for reset validity.
