Product details
Overview
MAX6354RVUK from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with active-low push-pull reset output referenced to VCC2, factory-set VCC1 threshold of 2.63V and VCC2 threshold of 1.58V, 100ms minimum reset timeout, 20µA supply current, and operation over -40°C to +85°C - used in multivoltage embedded systems to ensure reliable power-on and brownout reset sequencing.
For engineers reviewing the MAX6354RVUK datasheet, MAX6354RVUK pinout, MAX6354RVUK application, or MAX6354RVUK equivalent, key selection criteria include dual-supply monitoring capability, VCC2-referenced reset assertion, guaranteed RESET validity down to VCC2 = 1V, and compatibility with 5-pin SOT23 PCB layouts.
Technical Context
The MAX6354RVUK monitors two independent supply rails (VCC1 and VCC2) and asserts its single active-low push-pull RST output when either falls below its precision factory-set threshold - 2.63V for VCC1 and 1.58V for VCC2. Reset remains valid as long as at least one supply exceeds +1.0V.
It features a debounced TTL/CMOS-compatible manual-reset input (MR), supports no external components in dual-voltage systems, and provides power-supply transient immunity without requiring external filtering or timing capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 2.63V ±0.05V (factory-trimmed; ensures precise detection of +2.7V nominal rail dropout) |
| VCC2 Threshold | 1.58V ±0.03V (factory-trimmed; enables reliable monitoring of +1.6V or +1.8V logic rails) |
| Reset Timeout | 100–280ms (guaranteed minimum 100ms pulse width ensures full μP initialization before release) |
| Supply Current | 20µA typical (ultra-low quiescent draw extends battery life in portable equipment) |
| Operating Temp | -40°C to +85°C (fully specified across industrial temperature range) |
| RESET Validity | Valid down to VCC2 = 1.0V (ensures deterministic reset behavior during deep brownout) |
| Package | 5-pin SOT23 (compact footprint; compatible with high-density PCB layouts) |
Pinout & Package
MAX6354RVUK is housed in a 5-pin SOT23 package with gull-wing leads, optimized for reflow soldering and space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC2; drives low to assert reset, high-impedance off-state not applicable (push-pull) |
| 2 | GND | Ground reference for internal comparators and output stage; must be connected to system ground plane |
| 3 | MR | Debounced manual-reset input; pull low ≥1µs to force reset; internally pulled up ~63.5kΩ to VCC1 |
| 4 | VCC2 | Secondary supply input and monitoring rail; powers device when > VCC1; threshold = 1.58V |
| 5 | VCC1 | Primary supply input and monitoring rail; powers device when > VCC2; threshold = 2.63V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous precision tracking of two supplies (e.g., +2.7V core and +1.6V I/O) with separate thresholds |
| VCC2-referenced reset output | RST pin swings between GND and VCC2 - matches level-shifting requirements of low-voltage logic domains |
| No external components required | Eliminates need for RC timing networks, pull-up resistors, or external comparators in dual-rail supervision |
| Guaranteed operation down to 1.0V | RESET remains valid even as VCC2 decays to 1.0V - critical for orderly shutdown in battery-powered systems |
| Power-supply transient immunity | Rejects short-duration dips (<100ns at 100mV overdrive) without false triggering |
Applications
| Computers | Portable/Battery-Powered Equipment |
|---|---|
Use Scenario: Supervising dual-rail CPU core (+2.7V) and memory I/O (+1.6V) in compact embedded computers. IC Role / Device Role / Timing Role: Dual-threshold supervisor asserting reset when either rail drops below specification - prevents corrupted boot or data loss. Use Value: Ensures deterministic reset release only after both supplies stabilize above 2.63V and 1.58V respectively, eliminating race conditions. | Use Scenario: Monitoring main Li-ion battery (3.3V) and regulated LDO output (1.6V) in handheld medical devices. IC Role / Device Role / Timing Role: VCC2-referenced RST output directly interfaces 1.6V logic without level shifters; MR enables user-initiated safe shutdown. Use Value: 20µA quiescent current minimizes standby drain; 100ms reset pulse guarantees full MCU state recovery before wake-up. |
| Controllers | Multivoltage Systems |
Use Scenario: Power sequencing and fault detection in industrial PLC I/O modules with mixed 3.3V, 2.5V, and 1.6V domains. IC Role / Device Role / Timing Role: Monitors primary controller supply (VCC1 = 2.63V trip) and isolated sensor interface rail (VCC2 = 1.58V trip). Use Value: Push-pull RST referenced to VCC2 eliminates external pull-up, reducing BOM count and layout complexity. | Use Scenario: Supervising FPGA core (2.5V) and auxiliary I/O bank (1.6V) where reset must track the lower-voltage domain. IC Role / Device Role / Timing Role: Single-chip dual-monitor replaces discrete resistor-divider + comparator solutions; RST tied to VCC2 ensures correct logic levels. Use Value: Factory-trimmed thresholds eliminate calibration; guaranteed operation to 1.0V prevents spurious resets during brownout recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6354RVUT-T | 6-pin SOT23 package; identical electrical specs but includes unused pin 6 (NC); same VCC1/VCC2 thresholds and RST functionality | Requires different PCB footprint; suitable where board design already accommodates 6-pin variant or future upgrade path exists | Select MAX6354RVUT-T only if 6-pin layout is available; MAX6354RVUK offers smaller footprint and lower assembly cost. |
| TPS3808G15DBVR | Single-supply supervisor (1.5V threshold only); no dual-rail monitoring; open-drain RST; requires external pull-up | Cannot replace MAX6354RVUK in dual-voltage systems without redesign; lacks VCC2-referenced output and second threshold | Only consider TPS3808G15DBVR for single-rail 1.5V applications; not a functional substitute for MAX6354RVUK's dual-monitor architecture. |
Compared with MAX6354RVUT-T, the MAX6354RVUK saves board area and reduces component count via its 5-pin SOT23 footprint while retaining identical supervision functionality; versus TPS3808G15DBVR, it delivers true dual-rail monitoring with push-pull output, eliminating external biasing and enabling direct interfacing to low-voltage logic domains.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6354RVUK?
The MAX6354RVUK has a factory-set VCC1 threshold of 2.63V (±0.05V over temperature) and a VCC2 threshold of 1.58V (±0.03V). These values are laser-trimmed during production and documented in the Voltage-Threshold Levels table of the MAX6351–MAX6360 datasheet. The "RV" suffix explicitly denotes this threshold pair, and both thresholds are guaranteed across the full -40°C to +85°C operating range.
Does the MAX6354RVUK provide watchdog timer functionality?
No, the MAX6354RVUK does not include a watchdog timer. Watchdog capability is exclusive to the MAX6358/MAX6359/MAX6360 variants (identified by "UT-T" suffix and 6-pin SOT23 package). The MAX6354RVUK belongs to the MAX6352–MAX6354 subgroup, which offers dual-voltage monitoring and manual reset only - confirmed by its 5-pin configuration and absence of WDI pin in the pin description.
What is the function and voltage reference of the RST pin on the MAX6354RVUK?
The RST pin on the MAX6354RVUK is an active-low push-pull output referenced to VCC2. It drives low (≤0.3V at 50µA sink) when either VCC1 < 2.63V or VCC2 < 1.58V, and drives high (≥0.8 × VCC2 at 350µA source) otherwise. This VCC2 referencing allows direct interfacing with 1.6V logic without level shifters - a key differentiator from VCC1-referenced variants like MAX6353.
Can the MAX6354RVUK operate with supply voltages below 1.58V on VCC2?
Yes - the MAX6354RVUK guarantees valid RESET output operation down to VCC2 = 1.0V, even though its VCC2 threshold is 1.58V. As long as VCC2 remains ≥1.0V, the RST output remains functional and correctly asserted/deasserted per threshold conditions. Below 1.0V, device operation is undefined per Absolute Maximum Ratings, and RESET validity is no longer assured.
Is the MAX6354RVUK pin-compatible with other members of the MAX6351–MAX6360 family?
The MAX6354RVUK shares the same 5-pin SOT23 footprint and pinout as MAX6352 and MAX6353, but differs functionally: MAX6352 has open-drain RST, MAX6353 has VCC1-referenced RST, while MAX6354RVUK provides VCC2-referenced RST. Pin compatibility exists only within the 5-pin subgroup (MAX6352/MAX6353/MAX6354), not with 6-pin variants (e.g., MAX6355–MAX6360) which add RSTIN or WDI pins.
