Product details
Overview
MAX6336US24D1+T from Maxim Integrated is a push/pull, active-low microprocessor supervisory circuit designed for 1.8V–3.3V digital systems. It monitors VCC supply voltage with a factory-trimmed 2.4V reset threshold, asserts RESET for ≥1ms after power-up or manual reset, operates down to 0.7V VCC, and draws only 3.3µA at 2.5V - enabling reliable brownout detection in portable and automotive controllers.
For engineers reviewing the MAX6336US24D1+T datasheet, MAX6336US24D1+T pinout, MAX6336US24D1+T application, or MAX6336US24D1+T equivalent, key selection criteria include guaranteed RESET validity to 0.7V VCC, 1ms minimum reset timeout, SOT143 package compatibility with MAX811/MAX6314, and absence of external components required for basic operation.
Technical Context
The MAX6336US24D1+T implements a precision bandgap-based reset comparator with ±1.8% (25°C) and ±3% (-40°C to +125°C) threshold accuracy over temperature, immune to fast VCC transients up to 24µs at 10mV overdrive. Its internal debounced MR input features a 20kΩ pull-up resistor and requires only a momentary switch to GND for manual reset initiation.
It delivers a push/pull active-low RESET output with VOH ≥0.8VCC (ISOURCE = 200µA, VCC ≥1.8V) and VOL ≤0.4V (ISINK = 50µA, VCC ≥1.0V), ensuring clean logic-level signaling into high-impedance µP reset inputs without external pull-ups - unlike open-drain variants requiring external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.40V ±1.8% (25°C); ensures reliable detection of 2.5V rail brownout before µP malfunction |
| Reset Timeout | 1ms minimum; guarantees sufficient hold time for µP initialization on power-up |
| Supply Voltage Range | 0.7V to 5.5V; supports operation during deep brownout and battery discharge down to 0.7V |
| Quiescent Current | 3.3µA at 2.5V; enables multi-year battery life in always-on monitoring applications |
| MR Input Threshold | 0.5V max; compatible with 1.8V/2.5V logic levels and tolerant of slow-rising manual signals |
| Output Type | Push/pull active-low; eliminates need for external pull-up resistor on RESET line |
| Operating Temp | -40°C to +125°C; qualified for under-hood automotive and industrial embedded use |
Pinout & Package
MAX6336US24D1+T is housed in a lead-free 4-pin SOT143 package (3.0mm × 1.6mm × 1.1mm), pin-compatible with MAX811/MAX6314 and optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Return path for all internal circuitry; must be connected directly to system ground plane |
| 2 - RESET | Active-low reset output | Push/pull driver asserts low during VCC undervoltage or MR assertion; holds low for ≥1ms after recovery |
| 3 - MR | Manual reset input | Logic-low active input with internal 20kΩ pull-up; debounced internally - no external RC needed |
| 4 - VCC | Power supply input | Accepts 0.7V–5.5V; powers internal comparator and output stage; threshold sensing derived from this pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 0.7V operating voltage | Enables valid RESET assertion even as battery voltage collapses below 1.0V, critical for last-chance system shutdown |
| Factory-trimmed 2.4V threshold | Eliminates external resistor divider calibration; reduces BOM count and layout area vs. adjustable supervisors |
| 1ms minimum reset timeout | Meets minimum reset pulse width requirements of ARM Cortex-M0+, PIC16F, and STM32L0 families |
| Debounced MR input | Removes need for external Schmitt-trigger or RC filter, simplifying manual reset button interface |
| Transient-immune comparator | Rejects <24µs negative VCC glitches up to 10mV amplitude - prevents spurious resets in noisy power environments |
Applications
| Automotive Body Control Module | Industrial PLC I/O Subsystem |
|---|---|
Use Scenario: Monitoring 2.5V MCU supply in door module exposed to load-dump and cold-crank conditions. IC Role / Device Role / Timing Role: Primary brownout detector asserting RESET until VCC stabilizes above 2.4V after cranking recovery. Use Value: Guarantees µP remains held in reset during 0.7V–1.2V VCC sag, preventing corrupted EEPROM writes or erratic CAN bus behavior. | Use Scenario: Supervising 1.8V FPGA configuration voltage in modular I/O rack with hot-swap capability. IC Role / Device Role / Timing Role: Power-on reset generator and manual reset initiator via front-panel service button. Use Value: 1ms timeout ensures FPGA config state machine completes initialization; MR debounce avoids false triggers from mechanical switch bounce. |
| Portable Medical Sensor Node | Smart Energy Meter MCU |
Use Scenario: Battery-powered glucose monitor with Li-ion cell discharging from 4.2V to 2.8V; system must shut down cleanly below 2.4V. IC Role / Device Role / Timing Role: Low-voltage cutoff supervisor triggering controlled firmware shutdown sequence before brownout. Use Value: 3.3µA quiescent current extends shelf life; 0.7V operation allows full utilization of battery capacity down to end-of-discharge. | Use Scenario: Tamper-resistant electricity meter using secure bootloader that requires validated reset pulse on power-up. IC Role / Device Role / Timing Role: Certified power-on reset source meeting IEC 62056-6-2 timing requirements for secure boot integrity. Use Value: Factory-trimmed 2.4V threshold and ±3% temp drift ensure consistent reset assertion across -25°C to +70°C field operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX811TEUS24+T | Same SOT143 package, 2.4V threshold, but 20ms reset timeout and higher 10µA ICC | Not suitable where <10ms reset hold time is required (e.g., ultra-low-power wake-from-sleep sequences) | Select MAX6336US24D1+T when 1ms timeout and sub-4µA current are mandatory |
| TPS3124E18DBVR | 2.4V threshold, 1ms timeout, but only specified down to 1.0V VCC and lacks MR input | Cannot replace manual reset functionality; unsuitable for service-accessible equipment requiring field reset | Choose MAX6336US24D1+T where MR support and 0.7V operation are required |
Compared with MAX811TEUS24+T and TPS3124E18DBVR, the MAX6336US24D1+T uniquely combines 1ms timeout, 0.7V operation, integrated MR debounce, and push/pull drive - making it the only option meeting simultaneous low-current, deep-brownout, and manual-reset requirements in compact SOT143 form.

FAQ
What is the exact reset threshold voltage of MAX6336US24D1+T and how stable is it over temperature?
The MAX6336US24D1+T has a factory-trimmed nominal reset threshold of 2.40V, with ±1.8% tolerance at +25°C and ±3% over the full -40°C to +125°C operating range. This stability ensures consistent brownout detection across automotive and industrial environments without requiring recalibration or external compensation circuits.
Does MAX6336US24D1+T require external components to function as a reset supervisor?
No, the MAX6336US24D1+T requires zero external components for basic operation: its reset threshold is factory-trimmed, MR input includes an internal 20kΩ pull-up resistor, and the push/pull RESET output drives directly into µP reset pins without needing a pull-up. Only a decoupling capacitor on VCC is recommended per best practices.
Can MAX6336US24D1+T assert a valid RESET signal when VCC drops below 1.0V?
Yes - the MAX6336US24D1+T is guaranteed to maintain valid RESET assertion down to VCC = 0.7V. Its push/pull output structure ensures VOL ≤0.4V and VOH ≥0.8VCC even at 0.7V, enabling reliable reset hold during deep battery discharge or cold-crank events where other supervisors fail.
What is the purpose of the 'D1' suffix in MAX6336US24D1+T?
The 'D1' in MAX6336US24D1+T indicates a factory-programmed nominal reset timeout period of 1ms minimum. The 'D' denotes timeout selection, and '1' maps to the 1ms option (D2 = 20ms, D3 = 100ms), providing precise, fixed-duration reset pulses without external timing components.
Is MAX6336US24D1+T pin-compatible with legacy Maxim reset ICs?
Yes - the MAX6336US24D1+T uses the standard 4-pin SOT143 package and shares identical pinout (VCC, RESET, MR, GND) with MAX811/MAX812 and MAX6314/MAX6315, enabling drop-in replacement in existing designs without PCB modification or layout changes.
