Product details
Overview
MAX6352TYUK from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, featuring active-low open-drain reset output referenced to VCC1, precision factory-set thresholds of 3.08V (VCC1) and 2.19V (VCC2), 20µA supply current, and guaranteed RESET validity down to VCC1 ≥ 1.0V or VCC2 ≥ 1.0V - used for reliable power-on reset and undervoltage monitoring in multivoltage embedded systems.
For engineers reviewing the MAX6352TYUK datasheet, MAX6352TYUK pinout, MAX6352TYUK application, or MAX6352TYUK equivalent, this page delivers verified electrical parameters, exact pin functions, real-world use cases in portable equipment and controllers, and two confirmed alternative parts with documented functional and interface differences.
Technical Context
The MAX6352TYUK monitors two independent supply rails (VCC1 and VCC2) and asserts its open-drain RST output when either drops below its respective threshold (3.08V/2.19V). Reset remains valid as long as at least one supply exceeds +1.0V, enabling robust operation during brownout conditions.
It includes a debounced TTL/CMOS-compatible manual-reset input (MR), supports no external components for dual-rail supervision, and provides 100ms minimum power-on-reset pulse width with 20ppm/°C reset threshold tempco - ensuring timing stability across -40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 3.08V ±0.08V (TA = -40°C to +85°C); precise trip point for primary supply monitoring |
| VCC2 Threshold | 2.19V ±0.06V (TA = -40°C to +85°C); accurate secondary rail detection |
| Supply Current | 20µA typical (VCC1 = 5.5V, VCC2 = 3.6V); ultra-low quiescent power for battery-sensitive designs |
| Reset Pulse Width | 100–280ms; ensures reliable µP initialization across temperature and voltage variation |
| Operating Temp | -40°C to +85°C; fully specified for industrial and extended-temperature applications |
| Reset Validity | Guaranteed while VCC1 ≥ 1.0V or VCC2 ≥ 1.0V; enables reset assertion even during deep brownout |
| Package | 5-pin SOT23; compact footprint compatible with high-density PCB layouts |
Pinout & Package
MAX6352TYUK is housed in a 5-pin SOT23 package (package code U5-1), with exposed pad not electrically connected. Pin 1 is RST (open-drain), Pin 2 is GND, Pin 3 is MR, Pin 4 is VCC2, and Pin 5 is VCC1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low open-drain reset output | Requires external pull-up; referenced to VCC1; asserts low on any threshold violation |
| 2 - GND | Ground reference | Common return path for both supplies and internal circuitry |
| 3 - MR | Debounced manual-reset input | Pull low to force reset; internally pulled up (~63.5kΩ); glitch-filtered for noise immunity |
| 4 - VCC2 | Secondary supply input & monitor | Power source and monitored rail; threshold = 2.19V; must be ≤ VCC1 + 0.3V |
| 5 - VCC1 | Primary supply input & monitor | Power source and monitored rail; threshold = 3.08V; powers internal logic and defines RST pull-up domain |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of VCC1 (3.08V) and VCC2 (2.19V) with no shared reference dependency |
| Open-drain RST with VCC1-referenced drive | Enables level-shifting and wired-OR reset bus configurations without conflict on mixed-voltage systems |
| Guaranteed reset validity to 1.0V | Ensures deterministic reset behavior during severe brownout - critical for safe system shutdown |
| 20µA ultra-low supply current | Extends battery life in portable equipment; eliminates need for power-gating circuitry |
| 100ms min POR pulse width | Meets µP reset timing requirements across full temperature range without external RC timing |
Applications
| Portable/Battery-Powered Equipment | Intelligent Instruments |
|---|---|
Use Scenario: Power management in handheld test meters with dual Li-ion cell and 3.3V logic rails. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting open-drain reset to MCU when main battery drops below 3.08V or auxiliary rail falls below 2.19V. Use Value: Prevents erratic MCU operation during battery depletion; 20µA current draw extends runtime between charges. |
Use Scenario: Calibration and fault reporting in field-deployed environmental sensors with 5V analog front-end and 2.2V digital core. IC Role / Device Role / Timing Role: Monitors 3.08V system rail and 2.19V core rail; triggers reset if either sags due to load transients or aging batteries. Use Value: Eliminates need for discrete comparators and timers; 100ms reset pulse guarantees clean MCU restart before sensor data corruption. |
| Computers | Controllers |
Use Scenario: Embedded controller in fanless industrial PC with 3.3V I/O and 2.2V SoC supply. IC Role / Device Role / Timing Role: Provides synchronized reset to CPU and peripheral logic using single open-drain RST line pulled to 3.3V domain. Use Value: Ensures both voltage domains are stable before release; reset remains valid down to 1.0V on either rail for graceful failure response. |
Use Scenario: PLC I/O module requiring fail-safe reset during AC/DC converter ripple or transient events. IC Role / Device Role / Timing Role: Supervises 3.08V control logic rail and 2.19V isolated communication rail; asserts reset within 20µs of threshold breach. Use Value: 20ppm/°C tempco maintains threshold accuracy over wide ambient range; eliminates recalibration in uncontrolled environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6353TYUK | Replaces open-drain RST with VCC1-referenced push-pull output; identical thresholds and pinout | Eliminates external pull-up but requires VCC1-compatible reset sink; unsuitable for wired-OR buses | Select when driving a single µP reset pin directly and board space precludes pull-up resistor |
| TPS3808G30DBVR | Single-supply supervisor (3.0V threshold only); no VCC2 monitoring; 1.8–6.0V supply range | Cannot replace dual-rail supervision; requires separate IC for second rail or redesign to single-rail architecture | Choose only if system reduces to one monitored supply and lower cost per channel is prioritized over integration |
Compared with MAX6352TYUK, MAX6353TYUK offers push-pull drive for simpler µP interfacing but sacrifices bus-sharing capability, while TPS3808G30DBVR reduces integration by omitting VCC2 monitoring - making it a partial functional substitute only in single-rail contexts.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6352TYUK?
The MAX6352TYUK has a factory-set VCC1 threshold of 3.08V (±0.08V over -40°C to +85°C) and VCC2 threshold of 2.19V (±0.06V over same range). These values are defined by the "TY" suffix per the Voltage Threshold Levels table and are precision-trimmed during production - no external adjustment is required or supported for MAX6352TYUK.
Does the MAX6352TYUK include a watchdog timer function?
No, the MAX6352TYUK does not include a watchdog timer. Watchdog functionality is exclusive to the MAX6358/MAX6359/MAX6360 variants in the family. The MAX6352TYUK provides only dual-voltage monitoring, manual reset input, and open-drain reset output - confirmed by its 5-pin SOT23 pinout and absence of WDI pin.
Can the MAX6352TYUK operate with VCC1 and VCC2 supplied from different voltage sources?
Yes, the MAX6352TYUK is explicitly designed for independent dual-supply monitoring: VCC1 and VCC2 may be derived from separate regulators or power domains. Its datasheet specifies absolute maximum ratings of -0.3V to +6V on each supply pin, and reset assertion occurs if either drops below its respective threshold - no synchronization or sequencing dependency exists between them.
What is the purpose of the open-drain RST output on the MAX6352TYUK?
The open-drain RST output on the MAX6352TYUK allows wired-OR connection with other reset sources (e.g., multiple supervisors or power sequencers) on a shared reset bus. It requires an external pull-up resistor to a logic-compatible voltage (typically VCC1), enabling flexible level translation and fault-isolation in complex systems - a key distinction from push-pull variants like MAX6353TYUK.
Is the MAX6352TYUK RoHS-compliant and available in lead-free packaging?
Yes, the MAX6352TYUK is RoHS-compliant. Per Maxim's packaging documentation, lead-free versions are ordered by replacing the "-T" suffix with "+T" (e.g., MAX6352TYUK+T). The standard MAX6352TYUK-T uses leaded packaging; both variants share identical electrical specifications and 5-pin SOT23 mechanical form factor.
