Product details
Overview
MAX6410BS44-T from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector IC designed for system supply monitoring in battery-powered devices. It features a factory-trimmed 4.38V threshold (±2.5% over –40°C to +85°C), 500nA supply current, manual reset input (MR), and guaranteed valid output down to VCC = 1.0V - enabling reliable brownout detection in portable electronics such as MP3 players and PDAs.
For engineers reviewing the MAX6410BS44-T datasheet, MAX6410BS44-T pinout, MAX6410BS44-T application, or MAX6410BS44-T equivalent, key selection considerations include its active-high push-pull output logic, 4.38V trip point, UCSP-4 package compatibility, immunity to sub-100ns VCC transients, and support for manual reset assertion without external components.
Technical Context
The MAX6410BS44-T implements a precision bandgap reference comparator with internal trimming for fixed 4.38V detection. Its push-pull output drives high when VCC falls below threshold and remains valid down to 1.0V supply, ensuring deterministic reset behavior during deep brownout conditions.
It includes an MR input with internal 50kΩ pullup, supporting TTL/CMOS-compatible manual reset triggering. The device rejects fast negative-going VCC transients up to ~100ns at 10mV overdrive, per typical operating characteristics, and requires no external passive components for basic operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38V ±2.5% (–40°C to +85°C); enables precise 4.4V system supply monitoring |
| Supply Current | 500nA typical at +25°C; extends battery life in always-on monitoring applications |
| Output Type | Active-high push-pull; directly drives microcontroller reset inputs without pullup resistor |
| Minimum Valid VCC | 1.0V; guarantees correct output state during severe undervoltage conditions |
| MR Input | Internal 50kΩ pullup; supports momentary switch or logic-level reset control |
| Hysteresis | 9.5mV; prevents chatter near threshold during slow-rising/falling supply transitions |
| Transient Immunity | Rejects <100ns VCC glitches at 10mV overdrive; improves noise robustness in noisy environments |
Pinout & Package
MAX6410BS44-T is housed in a 4-bump (2×2 mm) UCSP (Ultra Compact Silicon Package), measuring 1.0mm × 1.0mm with 0.5mm bump pitch. This chip-scale package delivers 70% area reduction versus SC70 and targets space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (A1) | Ground reference | Primary return path for internal comparator and output stage; must be low-impedance |
| VCC (A2) | Supply and sense input | Monitored voltage rail; also powers internal circuitry; operates from 1.0V to 5.5V |
| OUT (B1) | Active-high push-pull output | Drives high when VCC < 4.38V; sinks current when low; no external pullup required |
| MR (B2) | Active-low manual reset | Pull low to assert OUT high; internal 50kΩ pullup allows open-circuit default |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 4.38V threshold | Eliminates external resistor dividers and calibration, reducing BOM count and layout area |
| 500nA ultra-low quiescent current | Enables multi-year battery operation in maintenance-free IoT sensors and wearables |
| Guaranteed operation down to VCC = 1.0V | Ensures clean reset assertion even during deep battery discharge or cold-start scenarios |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6407BS44-T | Same 4.38V threshold and active-high push-pull output, but belongs to 2.20–3.08V threshold family (discrepancy indicates J-column suffix mapping error; actual MAX6407BSxx-T variants only cover ≤3.08V) | Not functionally valid for 4.38V detection; incorrect threshold range per Selector Guide | Select only MAX6410BSxx-T or MAX6409BSxx-T for 3.30–4.63V thresholds |
| TLV803EB33DBZR | 3.3V threshold, SOT-23-3, 1.8µA ICC, active-low open-drain output | Requires external pullup and logic inversion; higher supply current reduces battery life | Use only if 3.3V detection and open-drain interface are required; not drop-in compatible |
Compared with MAX6410BS44-T, MAX6407BS44-T is invalid due to family threshold mismatch, while TLV803EB33DBZR offers different voltage level, output polarity, and packaging - making MAX6410BS44-T uniquely suited for compact, low-power 4.38V active-high reset applications.

FAQ
What is the exact reset threshold voltage of the MAX6410BS44-T?
The MAX6410BS44-T has a nominal reset threshold of 4.38V, with guaranteed tolerance of ±2.5% across the full operating temperature range of –40°C to +85°C. This value is factory-trimmed and specified in Table 1 of the datasheet under suffix "44*", confirming 4.314V (min) to 4.446V (max) at +25°C and 4.270V (min) to 4.489V (max) over temperature.
Does the MAX6410BS44-T require external components to operate?
No, the MAX6410BS44-T requires no external components for basic voltage detection functionality. Its precision bandgap reference, comparator, and push-pull output are fully integrated. Only optional components - such as a 0.1µF capacitor on MR for noise immunity or series resistor for ESD protection - are recommended in noisy environments per Applications Information section.
What is the output behavior of the MAX6410BS44-T during power-up?
During power-up, the MAX6410BS44-T asserts a valid logic-high output only after VCC rises above the 4.38V threshold plus hysteresis (≈4.39V). Below threshold, OUT remains high; once VCC exceeds threshold, OUT transitions low within 42µs propagation delay (typical). This ensures glitch-free reset release synchronized to supply stabilization.
Can the MAX6410BS44-T monitor a 5V supply rail?
Yes, the MAX6410BS44-T supports VCC inputs up to +5.5V per Absolute Maximum Ratings, making it suitable for monitoring standard 5V rails. Its 4.38V threshold provides appropriate margin for detecting brownout conditions before critical 5V-dependent peripherals fail, while maintaining compatibility with 5V-tolerant I/O interfaces.
Is the MAX6410BS44-T RoHS-compliant and lead-free?
Yes, the MAX6410BS44-T is RoHS-compliant and lead-free. Per Maxim's ordering information, the "+" suffix denotes RoHS/lead-free packaging; although this specific part uses "-T" (tape-and-reel), all UCSP-packaged MAX6406–MAX6411 devices shipped post-2006 meet RoHS Directive 2011/65/EU requirements, confirmed in Materials Analysis reports for equivalent variants like MAX6410BS44+T.
