Product details
Overview
MAX6352SVUK from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with open-drain active-low reset output, precision factory-set thresholds of 2.93V (VCC1) and 1.58V (VCC2), 20µA supply current, and guaranteed RESET validity down to VCC1 ≥ 1.0V or VCC2 ≥ 1.0V - used in multivoltage embedded systems to ensure reliable power-on reset and brownout detection.
For engineers reviewing the MAX6352SVUK datasheet, MAX6352SVUK pinout, MAX6352SVUK application, or MAX6352SVUK equivalent, this device delivers deterministic dual-supply monitoring with no external components, transient-immune reset assertion, and compatibility with TTL/CMOS manual reset inputs in space-constrained SOT23-5 designs.
Technical Context
The MAX6352SVUK monitors two independent supply rails (VCC1 and VCC2) and asserts its open-drain RST output low whenever either falls below its respective factory-trimmed threshold - 2.93V for VCC1 and 1.58V for VCC2. Its reset timeout period is guaranteed at 100ms minimum, with hysteresis and temperature coefficient (20ppm/°C) specified across –40°C to +85°C.
It features a debounced TTL/CMOS-compatible manual reset input (MR), operates with supply voltages from 1.2V to 5.5V per rail, and maintains valid reset state as long as either VCC1 or VCC2 remains ≥1.0V - enabling robust operation during asymmetric supply sequencing or partial rail collapse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 2.93V ±0.05V (factory-trimmed; ensures precise +3.0V rail supervision) |
| VCC2 Threshold | 1.58V ±0.03V (factory-trimmed; enables accurate +1.6V or +1.8V logic rail monitoring) |
| Supply Current | 20µA typical (enables ultra-low-power operation in battery-backed or portable systems) |
| Reset Timeout | 100ms min (guarantees sufficient processor initialization time after power-up) |
| Operating Temp | –40°C to +85°C (fully specified for industrial-grade embedded applications) |
| Reset Output Type | Active-low open-drain (supports wired-OR configuration and level-shifting with external pull-up) |
| MR Input Compatibility | TTL/CMOS-debounced (accepts standard logic-level manual reset signals without external filtering) |
Pinout & Package
MAX6352SVUK is housed in a 5-pin SOT23-5 package (JEDEC MO-178AA), with 1.6mm × 2.9mm footprint and 1.1mm max height - optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low open-drain reset output | Asserted low when VCC1 < 2.93V or VCC2 < 1.58V; requires external pull-up for logic-high state |
| 2 - GND | Ground reference | Common return path for both supply rails and internal comparators |
| 3 - MR | Debounced manual reset input | Pull low to force reset; internally debounced to reject noise spikes <100ns |
| 4 - VCC2 | Secondary supply input & monitor rail | Power source and monitored voltage (1.58V threshold); must be ≤ VCC1 |
| 5 - VCC1 | Primary supply input & monitor rail | Power source and monitored voltage (2.93V threshold); powers internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises two rails (e.g., +3.0V I/O and +1.6V core) with no shared threshold dependency |
| No external components required | Eliminates discrete resistors, capacitors, or comparators in dual-rail reset generation circuits |
| Power-supply transient immunity | Rejects VCC transients ≤200µs (at 0.5V overdrive), preventing false resets during switching noise |
| Guaranteed reset validity to 1.0V | Ensures functional reset assertion even during deep brownout conditions on either rail |
| Low quiescent current | 20µA max enables >10-year battery life in always-on supervisory applications |
Applications
| Industrial PLC Controllers | Portable Medical Sensors |
|---|---|
Use Scenario: A programmable logic controller uses separate +3.3V I/O and +1.6V FPGA core supplies, requiring coordinated reset assertion if either rail collapses. IC Role / Device Role / Timing Role: MAX6352SVUK acts as dual-rail supervisor, asserting open-drain RST to hold the FPGA and I/O peripherals in reset until both supplies stabilize above 2.93V and 1.58V respectively. Use Value: Prevents metastability and configuration corruption by guaranteeing synchronized release only after both rails meet precision thresholds. |
Use Scenario: A handheld ECG sensor operates from a single-cell Li-ion battery (2.8–4.2V), regulating +3.0V and +1.6V rails for analog front-end and digital subsystems. IC Role / Device Role / Timing Role: MAX6352SVUK monitors regulated outputs, triggering reset if battery sag causes VCC2 to dip below 1.58V while VCC1 remains nominal. Use Value: Enables fail-safe shutdown before analog signal chain distortion occurs, preserving measurement integrity during low-battery operation. |
| Automotive Body Control Modules | IoT Edge Node Gateways |
Use Scenario: A BCM integrates microcontroller, CAN transceiver, and LED drivers powered by +5.0V (CAN) and +1.8V (MCU core), subject to load-dump and cold-crank transients. IC Role / Device Role / Timing Role: MAX6352SVUK supervises +3.0V (derived from +5.0V) and +1.6V (derived from +1.8V), asserting RST during undervoltage events on either derived rail. Use Value: Provides rail-specific reset timing without external dividers, meeting AEC-Q100 transient immunity requirements via built-in glitch rejection. |
Use Scenario: An LPWAN gateway uses +3.3V MCU and +1.5V RF transceiver supplies, where intermittent solar charging causes slow VCC2 ramp-up. IC Role / Device Role / Timing Role: MAX6352SVUK holds RST active until VCC2 reaches 1.58V, ensuring RF IC initialization completes before firmware execution begins. Use Value: Eliminates race conditions between power rail stabilization and firmware boot sequence in energy-harvested systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G18DBVR | Fixed 1.8V VDD threshold, single-supply monitoring only; no VCC2 input | Lacks dual-rail capability - requires external resistor divider to monitor second rail | Select when only one supply needs precision supervision and board area permits external components |
| ADM6315-29DARTZ-RL7 | Single 2.93V threshold, no secondary voltage monitor; push-pull (not open-drain) RST output | Cannot supervise two independent rails simultaneously; incompatible with wired-OR reset buses | Choose only for simple single-rail reset where open-drain flexibility and dual monitoring are unnecessary |
Compared with TPS3808G18DBVR and ADM6315-29DARTZ-RL7, the MAX6352SVUK uniquely provides factory-trimmed dual-threshold supervision in a 5-pin SOT23 with open-drain output - eliminating design compromises in multivoltage systems requiring coordinated, rail-specific reset behavior without external components.

FAQ
What is the exact reset threshold voltage for each supply rail in the MAX6352SVUK?
The MAX6352SVUK has factory-trimmed reset thresholds of 2.93V for VCC1 and 1.58V for VCC2, with tolerances of ±0.05V and ±0.03V respectively, fully specified over –40°C to +85°C. These values are confirmed in the Voltage Threshold Levels table and Electrical Characteristics section of the MAX6352SVUK datasheet, and apply directly to this specific suffix variant.
Does the MAX6352SVUK include a watchdog timer function?
No, the MAX6352SVUK does not include a watchdog timer. Watchdog functionality is exclusive to the MAX6358/MAX6359/MAX6360 variants in the same family. The MAX6352SVUK provides only dual-voltage supervision and manual reset, with no WDI pin or timeout circuitry - as confirmed by its 5-pin SOT23-5 pinout and functional description.
What is the output type and drive capability of the RST pin on the MAX6352SVUK?
The MAX6352SVUK features an active-low open-drain RST output, requiring an external pull-up resistor. It sinks up to 1.2mA at VCC ≥ 2.7V (VOL ≤ 0.3V) and 3.2mA at VCC ≥ 4.5V (VOL ≤ 0.4V), enabling direct interface with 1.8V–5V logic families when paired with appropriate pull-up voltage and resistance.
Can the MAX6352SVUK operate with VCC1 and VCC2 supplied from different sources and sequenced independently?
Yes, the MAX6352SVUK supports independent supply sequencing: it asserts RST if either VCC1 drops below 2.93V or VCC2 drops below 1.58V, and guarantees valid reset output as long as at least one supply remains ≥1.0V. This behavior is explicitly documented in the Absolute Maximum Ratings and Detailed Description sections for the MAX6352SVUK.
Is the MAX6352SVUK pin-compatible with other devices in the MAX6351–MAX6360 family?
No - the MAX6352SVUK uses a 5-pin SOT23-5 package, while most other variants (e.g., MAX6355–MAX6360) use 6-pin SOT23-6. Pin functions differ significantly: MAX6352SVUK pins are RST/GND/MR/VCC2/VCC1, whereas 6-pin versions add dedicated RSTIN or WDI pins. Direct replacement is not possible without PCB redesign.
