Product details
Overview
The MAX6352RVUK+T 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, factory-set VCC1 threshold of 2.63V and VCC2 threshold of 1.58V, 20µA supply current, and guaranteed RESET validity down to VCC1 ≥ 1.0V or VCC2 ≥ 1.0V - used for reliable power-on reset and supply monitoring in multivoltage embedded systems.
For engineers reviewing the MAX6352RVUK+T datasheet, MAX6352RVUK+T pinout, MAX6352RVUK+T application, or MAX6352RVUK+T equivalent, key selection criteria include dual-supply threshold accuracy (±0.05V over temperature), open-drain RST drive capability at low VCC (≥50µA sink @ 1.2V), manual-reset debouncing, and compatibility with 1.2V–5.5V supply rails in space-constrained industrial controllers.
Technical Context
This device implements independent precision voltage comparators for two supply rails (VCC1 and VCC2), with reset assertion triggered if either supply drops below its factory-trimmed threshold. The open-drain RST output requires an external pullup and remains valid as long as at least one supply exceeds +1.0V.
It includes a debounced TTL/CMOS-compatible manual-reset input (MR) that forces reset when pulled low, with glitch rejection (100ns) and sub-microsecond MR-to-RST delay (0.1µs). No watchdog timer or third-voltage monitor is present - confirmed by part number mapping and selector guide.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 2.63V ±0.05V over -40°C to +85°C - ensures accurate reset initiation for 2.7V nominal supplies |
| VCC2 Threshold | 1.58V ±0.05V over -40°C to +85°C - supports monitoring of 1.6V/1.8V auxiliary rails |
| Supply Current | 20µA typical at 5.5V/3.6V - enables battery-backed operation for >10 years in low-power systems |
| Reset Timeout | 100ms minimum - guarantees sufficient processor initialization time after power-up |
| RST Output Type | Active-low open-drain - allows wired-OR configuration and level translation across voltage domains |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded control environments |
| Reset Validity | Valid down to VCC1 ≥ 1.0V or VCC2 ≥ 1.0V - maintains system integrity during brownout conditions |
Pinout & Package
MAX6352RVUK+T is housed in a RoHS-compliant 5-pin SOT23 package (U5-1 outline, 90-0174 land pattern), with 1.3mm × 2.2mm footprint and 0.95mm height - suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low open-drain reset output | Drives low during fault; requires external pullup; referenced to VCC1 rail |
| 2 - GND | Ground reference | Common return path for both supply monitors and logic inputs |
| 3 - MR | Debounced manual-reset input | Pull low to force reset; internally pulled up (~63.5kΩ); glitch-filtered |
| 4 - VCC2 | Secondary supply input & monitor | Power source and monitored rail; threshold = 1.58V; must be ≤ VCC1 |
| 5 - VCC1 | Primary supply input & monitor | Power source and monitored rail; threshold = 2.63V; powers internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous tracking of VCC1 (2.63V) and VCC2 (1.58V) with no shared reference dependency |
| Open-drain RST with wide VCC validity | RST remains functional even if VCC1 or VCC2 drops to 1.0V - critical for brownout resilience |
| Low-power operation | 20µA quiescent current enables integration into always-on subsystems without compromising battery life |
| Robust manual reset interface | MR input includes 100ns glitch rejection and 1µs minimum pulse width tolerance - immune to board-level noise |
| Supply transient immunity | Withstands VCC transients <150ns at 0.5V overdrive - prevents false resets during switching noise |
Applications
| Industrial PLC I/O Modules | Battery-Powered Data Loggers |
|---|---|
Use Scenario: Monitoring 2.7V microcontroller core supply and 1.6V sensor interface rail in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: Dual-threshold supervisor asserting open-drain RST to hold MCU in reset until both rails stabilize post-power-up. Use Value: Prevents firmware execution on marginal supplies using factory-trimmed 2.63V/1.58V thresholds with ±0.05V accuracy over temperature. | Use Scenario: Ensuring clean boot of ARM Cortex-M0+ in solar-charged remote sensors operating across -40°C to +85°C. IC Role / Device Role / Timing Role: Providing 100ms minimum reset pulse while drawing only 20µA - extending coin-cell lifetime beyond 10 years.

IC Role / Device Role / Timing Role: Generating synchronized reset for dual-domain power sequencing without external timing components. Use Value: Factory-trimmed thresholds eliminate calibration overhead; SOT23-5 footprint fits tight meter PCB constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EC26DBVR | Single-supply (2.63V only), push-pull RST, no VCC2 monitor | Lacks dual-rail supervision - requires separate IC for second supply | Select when only one supply needs monitoring and push-pull output is preferred |
| ADM6315-26ARTZ-RL7 | 2.63V single-threshold, open-drain RST, 1.6µA supply current, no VCC2 input | No secondary supply monitoring capability - not functionally equivalent | Choose only for ultra-low-power single-rail applications where VCC2 monitoring is unnecessary |
Compared with TLV803EC26DBVR and ADM6315-26ARTZ-RL7, the MAX6352RVUK+T uniquely provides integrated dual-threshold supervision in a single 5-pin SOT23, eliminating BOM count and layout area versus discrete solutions - essential for compact multivoltage systems requiring coordinated reset behavior.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6352RVUK+T?
The MAX6352RVUK+T has a factory-set VCC1 threshold of 2.63V (±0.05V over -40°C to +85°C) and VCC2 threshold of 1.58V (±0.05V over same range), as defined by the "RV" suffix per the Voltage Threshold Levels table - these values are laser-trimmed and guaranteed in production test.
Does the MAX6352RVUK+T include a watchdog timer function?
No, the MAX6352RVUK+T does not include a watchdog timer. Watchdog functionality is exclusive to MAX6358/MAX6359/MAX6360 variants (6-pin SOT23), as confirmed by the Selector Guide and Pin Configurations section - the MAX6352RVUK+T is a 5-pin device with RST, GND, MR, VCC2, and VCC1 only.
What is the maximum supply voltage the MAX6352RVUK+T can tolerate on VCC1 and VCC2 pins?
The MAX6352RVUK+T supports VCC1 and VCC2 voltages from 1.2V to 5.5V over the full operating temperature range (-40°C to +85°C), with absolute maximum rating of -0.3V to +6V - exceeding this risks permanent damage per Absolute Maximum Ratings.
Can the MAX6352RVUK+T operate with only one supply connected?
Yes, the MAX6352RVUK+T guarantees valid RST output as long as either VCC1 ≥ 1.0V or VCC2 ≥ 1.0V - enabling operation during asymmetric power-up sequences or partial supply failures, with reset asserted if either rail falls below its respective threshold.
Is the RST output of the MAX6352RVUK+T push-pull or open-drain?
The RST output of the MAX6352RVUK+T is active-low open-drain, requiring an external pullup resistor - confirmed by Pin Description (page 6), Selector Guide (page 8), and functional diagram (page 7) which explicitly designate MAX6352 as "open-drain output".
