Product details
Overview
MAX6352TYUK-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, 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 in multivoltage embedded systems requiring reliable power-on and brownout detection.
For engineers reviewing the MAX6352TYUK-T datasheet, MAX6352TYUK-T pinout, MAX6352TYUK-T application, or MAX6352TYUK-T equivalent, this page delivers verified threshold voltages, reset timing behavior, manual-reset debounce characteristics, open-drain drive capability, and temperature-stable operation across –40°C to +85°C - critical for industrial controller and portable equipment design.
Technical Context
The MAX6352TYUK-T monitors two independent supply rails (VCC1 and VCC2) with fixed, factory-trimmed thresholds - 3.08V ±0.08V for VCC1 and 2.19V ±0.06V for VCC2 - and asserts its open-drain RST output low when either supply drops below its respective trip point. Its reset timeout period is guaranteed 100ms to 280ms after both supplies exceed thresholds.
It includes a debounced TTL/CMOS-compatible manual-reset input (MR), supports valid reset assertion as long as either VCC1 or VCC2 remains ≥1.0V, and features power-supply transient immunity up to 250µs at 100mV overdrive - enabling robust operation in noisy, battery-powered environments without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 3.08V ±0.08V at +25°C; ensures precise 3.3V rail monitoring with ±2.6% tolerance over –40°C to +85°C |
| VCC2 Threshold | 2.19V ±0.06V at +25°C; enables accurate supervision of 2.2V or 2.5V auxiliary rails |
| Reset Timeout Period | 100–280ms; guarantees minimum 100ms reset pulse width for reliable µP initialization |
| Supply Current | 20µA typical; allows integration into ultra-low-power battery-backed systems |
| Operating Temperature | –40°C to +85°C; fully specified and guaranteed for industrial-grade embedded applications |
| RESET Validity Range | Valid as long as VCC1 ≥ 1.0V or VCC2 ≥ 1.0V; ensures reset integrity during deep brownout conditions |
| Output Type | Active-low open-drain RST; permits wired-OR configuration and level-shifting via external pull-up |
Pinout & Package
MAX6352TYUK-T is housed in a RoHS-compliant 5-pin SOT23 package (U5-1 outline), footprint compatible with standard 5-pin SOT-23 land pattern 90-0174, with 1.27mm pitch and exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low open-drain reset output | Asserted low when VCC1 < 3.08V or VCC2 < 2.19V; requires external pull-up for logic-high state |
| 2 - GND | Ground reference | Common return path for internal comparators, MR input, and reset generator |
| 3 - MR | Debounced manual-reset input | Pull low to force reset; internally debounced; valid over full VCC1 range; no external RC needed |
| 4 - VCC2 | Secondary supply input and monitor rail | Monitors 2.19V threshold; powers internal circuitry when VCC2 > VCC1; must be ≤ VCC1 + 0.3V |
| 5 - VCC1 | Primary supply input and monitor rail | Monitors 3.08V threshold; primary power source; defines RST output voltage reference when pulled high externally |
Key Features
| Feature | Design Value |
|---|---|
| Dual-voltage monitoring with fixed thresholds | Simultaneously supervises 3.08V and 2.19V rails without trimming resistors or calibration |
| Open-drain reset output | Enables shared reset bus across multiple ICs and flexible voltage-level translation via external pull-up |
| Guaranteed reset validity to 1.0V | Ensures deterministic reset assertion even during severe brownout where VCC1 or VCC2 collapses to 1.0V |
| 20µA ultra-low quiescent current | Minimizes battery drain in always-on portable instrumentation and remote sensor nodes |
| 100ms minimum power-on reset pulse | Meets µP reset timing requirements for ARM Cortex-M and PIC microcontrollers without external delay circuits |
| Power-supply transient immunity | Rejects transients ≤250µs duration at 100mV overdrive - prevents false resets in switching regulator environments |
Applications
| Industrial Controllers | Portable Medical Devices |
|---|---|
Use Scenario: PLC I/O modules powered by dual rails (3.3V logic, 2.2V analog) IC Role / Device Role / Timing Role: Dual-rail supervisor asserting system-wide reset on either rail undervoltage Use Value: Prevents firmware corruption during partial power loss by guaranteeing 100ms+ reset hold time and valid reset down to 1.0V |
Use Scenario: Battery-powered glucose meter with 3.3V MCU and 2.2V sensor interface IC Role / Device Role / Timing Role: Low-current supervisor ensuring safe shutdown before battery depletion Use Value: 20µA supply current extends single-CR2032 battery life beyond 5 years in standby mode |
| Automotive Body Control Modules | Smart Energy Meters |
Use Scenario: 12V-to-3.3V/2.2V DC-DC powered BCM with cold-crank voltage dips IC Role / Device Role / Timing Role: Brownout detector immune to 250µs transients during load-dump events Use Value: Eliminates need for external RC filter or Schmitt-trigger buffer, reducing BOM count |
Use Scenario: Dual-rail meter SoC (3.3V core, 2.2V RTC/backup domain) operating from supercapacitor IC Role / Device Role / Timing Role: Ensures clean reset during capacitor discharge transition from main to backup power Use Value: Guaranteed RESET validity at VCC1 = 1.0V enables graceful switchover with no data loss |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6352SYUK-T | VCC1 threshold = 2.93V (vs. 3.08V); VCC2 threshold = 2.19V unchanged | Better suited for 2.8V/2.2V dual-rail systems; less margin for 3.3V rail tolerance | Select when supervising 2.8V logic rail instead of 3.3V; same pinout and package |
| TPS3808G12DBVR | Single-supply (1.2V threshold only); no dual-rail monitoring; 350ms reset timeout | Requires separate supervisors for each rail; lacks VCC2 monitoring capability | Use only if system has single-rail architecture or can accept discrete supervision per rail |
Compared with MAX6352TYUK-T, MAX6352SYUK-T offers tighter matching to 2.8V nominal rails but sacrifices 3.3V margin, while TPS3808G12DBVR provides longer reset timeout but cannot replace dual-voltage supervision - making MAX6352TYUK-T uniquely suitable for compact, cost-sensitive 3.3V/2.2V systems needing integrated fault detection.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6352TYUK-T?
The MAX6352TYUK-T has a factory-set VCC1 threshold of 3.08V ±0.08V (±2.6%) and VCC2 threshold of 2.19V ±0.06V (±2.7%), both specified over –40°C to +85°C. These values are laser-trimmed during production and documented in the Voltage Threshold Levels table of the MAX6351–MAX6360 datasheet. The "TY" suffix explicitly denotes this 3.08V/2.19V combination.
Does the MAX6352TYUK-T include a watchdog timer function?
No, the MAX6352TYUK-T does not include a watchdog timer. Watchdog functionality is only present in the MAX6358/MAX6359/MAX6360 variants (6-pin SOT23). The MAX6352TYUK-T belongs to the base supervisory group with dual-voltage monitoring, manual reset, and open-drain reset output - confirmed by its 5-pin package and absence of WDI pin in the pin configuration.
What is the maximum supply voltage the MAX6352TYUK-T can tolerate on VCC1 and VCC2 pins?
The MAX6352TYUK-T supports VCC1 and VCC2 inputs from 1.2V to 5.5V over temperature, with absolute maximum rating of –0.3V to +6V. However, the reset output remains valid only when either supply is ≥1.0V, and the device guarantees correct operation only within the 1.2V–5.5V range per Electrical Characteristics. Exceeding 5.5V risks permanent damage.
Can the MAX6352TYUK-T drive a reset line directly without an external pull-up resistor?
No - the MAX6352TYUK-T features an open-drain RST output and requires an external pull-up resistor to establish a logic-high state. The datasheet specifies VOL ≤0.3V at ISINK = 50µA when VCC ≥1.2V, confirming active-low sinking capability only. A typical 10kΩ pull-up to VCC1 or another compatible rail is required for proper reset signaling.
Is the MAX6352TYUK-T pin-compatible with other members of the MAX6351–MAX6360 family?
The MAX6352TYUK-T shares the same 5-pin SOT23 footprint with MAX6352xxUK-T, MAX6353xxUK-T, and MAX6354xxUK-T variants, but is not pin-compatible with 6-pin versions (e.g., MAX6351, MAX6355). Pin 1 is RST (open-drain), differing from push-pull RST1/RST2 configurations in 6-pin models - direct substitution requires PCB layout verification.
