Product details
Overview
The MAX6736XKVHD3 from Maxim Integrated is a dual-voltage microprocessor supervisor IC with two factory-trimmed reset thresholds (VTH1 = 2.188V, VTH2 = 1.575V), open-drain active-low RESET output, manual reset input (MR), and 150ms minimum reset timeout period. It monitors primary (VCC1) and secondary (VCC2) supply rails in portable and multivoltage systems, asserting reset if either falls below its threshold. Designed for battery-powered equipment and notebook computers, it draws only 6µA typical supply current.
For engineers reviewing the MAX6736XKVHD3 datasheet, MAX6736XKVHD3 pinout, MAX6736XKVHD3 application, or MAX6736XKVHD3 equivalent, key selection considerations include its SC70-5 package, dual fixed-threshold supervision, MR-driven reset assertion, 150ms timeout, and compatibility with low-voltage core/I/O rail monitoring down to 0.9V.
Technical Context
The MAX6736XKVHD3 implements independent voltage comparators for VCC1 and VCC2, each referenced to precision internal bandgap-derived thresholds. Reset assertion occurs when either supply drops below its trimmed VTH, and the internal timer enforces a guaranteed minimum 150ms reset pulse width after all supplies recover.
It features an internal 1.5kΩ pullup on MR, supports CMOS-logic-level manual reset triggering, and uses open-drain RESET requiring external pullup. The device operates across -40°C to +85°C and maintains valid reset state while VCC1 or VCC2 exceeds 1.2V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold (VTH1) | 2.188V ±0.050V - factory-trimmed for reliable I/O rail supervision at 2.2V nominal |
| VCC2 Threshold (VTH2) | 1.575V ±0.050V - factory-trimmed for core rail supervision at 1.6V nominal |
| Reset Timeout Period | 150ms min - ensures µP completes power-up initialization before release |
| Supply Current (ICC1) | 6µA typical - enables multi-year battery life in portable applications |
| Operating Temperature | -40°C to +85°C - qualified for industrial and consumer embedded environments |
| Package | 5-pin SC70 - 2.0mm × 1.25mm footprint, surface-mount compatible with high-density PCBs |
| RESET Output Type | Open-drain active-low - allows wired-OR configuration and level-shifting flexibility |
Pinout & Package
MAX6736XKVHD3 is housed in a 5-pin SC70-5 package (2.0mm × 1.25mm, 0.65mm pitch), optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Active-low reset output | Open-drain output asserted low during fault or MR activation; requires external pullup resistor |
| 2 - GND | Ground reference | Common return path for all internal circuitry and external bias networks |
| 3 - MR | Manual reset input | Active-low input with internal 1.5kΩ pullup to VCC1; triggers reset when pulled ≤0.3×VCC1 |
| 4 - VCC2 | Secondary supply monitor input | Input for core voltage rail; compared against 1.575V threshold |
| 5 - VCC1 | Primary supply monitor input | Input for I/O voltage rail; compared against 2.188V threshold; powers internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual fixed-voltage supervision | Simultaneously monitors two independent rails (VCC1/VCC2) with no external components required |
| Low 6µA quiescent current | Extends battery runtime in portable devices without compromising supervision reliability |
| Factory-trimmed thresholds | 2.188V/1.575V thresholds guaranteed over temperature, eliminating calibration overhead |
| 150ms minimum reset timeout | Ensures µP reset pulse meets JEDEC JESD82-1B timing requirements for safe initialization |
| MR input with internal pullup | Reduces BOM count by eliminating external pullup resistor for manual reset button interface |
Applications
| Portable Power Management | Notebook System Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6736XKSTD3 | VTH1 = 2.925V, VTH2 = 2.188V - higher thresholds for 3.0V/2.2V rail pairs | Suitable for systems with 3.0V I/O and 2.2V core, not 2.2V/1.6V | Select when supervising higher-voltage dual-rail configurations; same SC70-5 package and 150ms timeout |
| MAX6737XKVHD3 | Push-pull RESET output instead of open-drain; identical thresholds and timing | Eliminates need for external pullup but lacks wired-OR capability | Choose for simplified interface where level-shifting or bus arbitration is unnecessary |
Compared with MAX6736XKVHD3, MAX6736XKSTD3 shifts both thresholds upward for 3.0V/2.2V systems, while MAX6737XKVHD3 replaces open-drain with push-pull RESET-offering simpler drive but sacrificing flexibility in multi-source reset architectures.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6736XKVHD3?
The MAX6736XKVHD3 has a factory-trimmed VCC1 reset threshold of 2.188V, with tolerance of ±0.050V over the -40°C to +85°C temperature range. This value is confirmed in Table 2 of the datasheet under suffix "Y", corresponding to the "V" in the part number. The threshold is internally generated and requires no external calibration.
Does the MAX6736XKVHD3 support manual reset functionality?
Yes, the MAX6736XKVHD3 includes a dedicated active-low manual reset (MR) input on Pin 3. It features an internal 1.5kΩ pullup resistor to VCC1, allowing direct connection to a momentary switch to ground. When MR is pulled low for ≥1µs, RESET asserts and remains low for the full 150ms timeout period after MR returns high.
What package type and dimensions does the MAX6736XKVHD3 use?
The MAX6736XKVHD3 is packaged in a 5-pin SC70-5 (also labeled SC70) case measuring 2.0mm × 1.25mm with 0.65mm lead pitch. This ultra-small outline package is RoHS-compliant and designed for reflow soldering in high-density portable PCB layouts.
Is the RESET output of the MAX6736XKVHD3 open-drain or push-pull?
The MAX6736XKVHD3 features an open-drain active-low RESET output on Pin 1. This requires an external pullup resistor to the appropriate logic rail (typically VCC1 or host µP I/O voltage). The open-drain architecture enables wired-OR reset bus configurations and level translation across different voltage domains.
What is the guaranteed minimum reset timeout period for the MAX6736XKVHD3?
The MAX6736XKVHD3 guarantees a minimum reset timeout period of 150ms (D3 suffix), with typical value 225ms and maximum 300ms over temperature. This timeout begins after both VCC1 and VCC2 exceed their respective thresholds and ensures sufficient hold time for microprocessor initialization sequences.
