Product details
Overview
MAX6336US23D3-T from Maxim Integrated is a push/pull active-low microprocessor supervisory circuit designed to monitor 2.3V power supplies in ultra-low-voltage embedded systems. It asserts reset when VCC falls below 2.30V (±3% over temperature) or upon debounced manual reset, with a guaranteed 100ms minimum timeout and valid RESET output down to VCC = 0.7V. Used in portable equipment and automotive controllers for reliable brownout protection.
For engineers reviewing the MAX6336US23D3-T datasheet, MAX6336US23D3-T pinout, MAX6336US23D3-T application, or MAX6336US23D3-T equivalent, key selection criteria include its 2.3V factory-trimmed threshold, 100ms reset timeout, push/pull output structure, SOT143-4 package, and operation down to 0.7V supply - critical for battery-powered and wide-temperature industrial designs.
Technical Context
The MAX6336US23D3-T implements a precision bandgap-based voltage comparator with factory-trimmed 2.30V reset threshold (±1.8% at +25°C, ±3% over -40°C to +125°C) and built-in hysteresis to reject fast VCC transients up to 24µs at 10V/ms slew rate. Its internal debounced manual-reset input eliminates external RC networks.
It features a push/pull RESET output capable of sourcing 200µA at VCC ≥1.8V (VOH ≥0.8VCC) and sinking 50µA at VCC ≥1.0V (VOL ≤0.4V), ensuring robust interface with µP reset inputs across its full 0.7V–5.5V operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.30V ±3% over -40°C to +125°C - ensures accurate brownout detection for 2.3V logic domains |

Pinout & Package
MAX6336US23D3-T is housed in a 4-pin SOT143 package (1.3mm × 2.1mm, 0.95mm height), optimized for space-constrained PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Return path for all internal circuitry and RESET output current |
| 2 - RESET | Active-low push/pull output | Drives µP reset pin low during fault; actively pulls high when deasserted |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX811SUR23D3-T | Same SOT143-4 package, 2.3V threshold, but only 1.6V min VCC and 20ms timeout | Limited to commercial temp range (-40°C to +85°C); not rated for automotive under-hood use | Select when cost sensitivity outweighs extended temperature and long timeout needs |
| TLV803EB23DBZR | 2.32V threshold, 350ms timeout, 0.9V min VCC, open-drain output | Requires external pull-up; higher ICC (1.8µA typ) but wider VCC range (0.9V–6V) | Choose for systems needing longer reset hold time or interfacing with bidirectional µP reset pins |
Compared with MAX811SUR23D3-T and TLV803EB23DBZR, the MAX6336US23D3-T uniquely combines automotive-grade temperature range, 100ms timeout, push/pull drive, and 0.7V operation - making it optimal for safety-critical, battery-depleted, or thermally harsh deployments where reset integrity must be guaranteed across full voltage and temperature extremes.

FAQ
What is the exact reset threshold voltage for MAX6336US23D3-T and how does it vary with temperature?
The MAX6336US23D3-T has a factory-trimmed nominal reset threshold of 2.30V, with ±1.8% tolerance at +25°C and ±3% over the full -40°C to +125°C operating range. This means the actual threshold remains between 2.23V and 2.37V across temperature, ensuring consistent brownout detection for 2.3V logic domains without external calibration.
Does MAX6336US23D3-T require an external pull-up resistor on the RESET pin?
No, MAX6336US23D3-T does not require an external pull-up resistor because it features a push/pull output stage. The RESET pin actively drives high (≥0.8VCC) when deasserted and low (≤0.4V) when asserted, enabling direct connection to microcontroller reset inputs without additional components - unlike open-drain alternatives such as MAX6337US23D3-T.
What is the minimum supply voltage at which MAX6336US23D3-T guarantees valid RESET output behavior?
The MAX6336US23D3-T guarantees correct RESET output state down to VCC = 0.7V, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables. Below this voltage, the device may cease operation, but within its specified 0.7V–5.5V range, RESET remains fully functional - a key advantage for deep-battery-discharge applications.
How is the 100ms reset timeout period implemented in MAX6336US23D3-T?
The 100ms reset timeout in MAX6336US23D3-T is factory-programmed using on-chip timing circuitry - no external capacitor or resistor is needed. After VCC rises above 2.30V or MR is released, RESET remains asserted for a minimum of 100ms (150ms typical, 200ms max), satisfying boot-time requirements of modern microcontrollers without design overhead.
Is MAX6336US23D3-T pin-compatible with legacy supervisory ICs like MAX811?
Yes, MAX6336US23D3-T is explicitly pin-compatible with MAX811/MAX812 and MAX6314/MAX6315 in the SOT143-4 package. Pin 1 (GND), Pin 2 (RESET), Pin 3 (MR), and Pin 4 (VCC) match identically, enabling drop-in replacement while delivering improved specs: tighter threshold accuracy, lower ICC, and extended temperature range.
