Product details
Overview
MAX6462XR16+T from Maxim Integrated is a precision ultra-low-power voltage detector IC designed for battery and power-supply monitoring in space-constrained, low-current systems. It features a 1.6V nominal trip threshold (VTH− = 1.600V typ), ±2.5% threshold accuracy over −40°C to +125°C, 1.0µA supply current at 3.6V, and 17µs propagation delay. It is used in portable medical devices and battery-powered instrumentation to ensure reliable power-on reset and brownout detection.
For engineers reviewing the MAX6462XR16+T datasheet, MAX6462XR16+T pinout, MAX6462XR16+T application, or MAX6462XR16+T equivalent, key selection criteria include its SC70-3 package, active-high push-pull output, 5% internal hysteresis, and guaranteed operation down to 1.2V supply - critical for Li-ion and coin-cell powered designs requiring stable undervoltage supervision without external components.
Technical Context
The MAX6462XR16+T implements a precision bandgap reference and comparator with internally trimmed resistor networks to set fixed VTH− = 1.600V (±2.5%) and VTH+ = 1.672V (VTH− × 1.05). Its hysteresis prevents output chatter during slow-rising/falling supply transitions near threshold.
This device belongs to the MAX6461–MAX6466 family of voltage detectors (not supervisory circuits with timeout), so it asserts output immediately on VCC drop below VTH− and releases immediately on VCC rise above VTH+, with no built-in reset timeout period - distinguishing it from MAX6464–MAX6466 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 1.0µA at 3.6V - enables multi-year battery life in always-on monitoring applications |
| Threshold Voltage (VTH−) | 1.600V ±2.5% (−40°C to +125°C) - matches standard 1.6V Li-ion cutoff and logic supply rails |
| Threshold Hysteresis | 5% (VTH+ = VTH− × 1.05) - eliminates false triggering during noisy or slowly varying VCC |
| Propagation Delay | 17µs (VCC falling at 10mV/µs) - ensures fast response to brownout events without excessive latency |
| Operating Voltage Range | 1.2V to 6.0V - supports operation down to near-dead battery levels while monitoring up to 5.5V systems |
| Output Type | Push-pull, active-high - drives logic inputs directly without pull-up resistors or level-shifting |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood and industrial embedded environments |
Pinout & Package
MAX6462XR16+T is housed in a 3-pin SC70-3 package (2.0mm × 2.1mm × 0.95mm), optimized for high-density PCB layouts in portable equipment. Pin 1 is OUT, Pin 2 is GND, and Pin 3 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Active-high push-pull output | Drives CMOS/TTL loads directly; asserts HIGH when VCC < VTH−, returns LOW when VCC > VTH+ |
| 2 (GND) | Ground reference | Return path for internal bandgap and comparator; must be low-impedance for threshold stability |
| 3 (VCC) | Supply input & monitored voltage | Single pin serves as both power source and monitored rail - no separate sense input required |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Internally trimmed resistors and bandgap eliminate calibration parts and layout area |
| Ultra-low 1.0µA quiescent current | Reduces standby power loss by >90% vs. discrete comparator-based solutions |
| ±2.5% threshold accuracy over full temperature range | Ensures deterministic reset behavior across automotive and industrial thermal profiles |
| Immunity to short voltage transients | Rejects sub-20µs glitches (e.g., switching noise, ESD coupling) without false assertion |
| SC70-3 footprint compatibility | Enables drop-in replacement for other 3-pin voltage monitors in existing 2.0×2.1mm layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB16DBVR | 1.6V threshold, 0.8µA ICC, SOT-23-3, open-drain active-low output | Requires external pull-up; not pin-compatible due to active-low polarity and different output stage | Select when open-drain interface to mixed-voltage logic is needed; verify pull-up sizing for timing compliance. |
| APX803S-16SA-7 | 1.6V threshold, 1.2µA ICC, SOT-23-3, push-pull active-low output | Same package but inverted output polarity; lacks hysteresis specification in datasheet | Use only if active-low reset signaling is required and hysteresis margin can be verified externally. |
Compared with TLV803EB16DBVR and APX803S-16SA-7, the MAX6462XR16+T provides guaranteed 5% hysteresis, active-high push-pull drive, and tighter ±2.5% threshold accuracy over temperature - making it preferable for systems where deterministic reset timing and direct logic interfacing are essential without added passives.

FAQ
What is the exact voltage threshold of MAX6462XR16+T?
The MAX6462XR16+T has a nominal lower trip threshold (VTH−) of 1.600V at +25°C, with guaranteed tolerance of ±2.5% over −40°C to +125°C (1.560V to 1.640V). Its upper threshold (VTH+) is 1.672V typ (VTH− × 1.05), providing 5% hysteresis to prevent output oscillation near the trip point. These values are factory-trimmed and do not require external calibration.
Does MAX6462XR16+T include a reset timeout period?
No, the MAX6462XR16+T does not include a reset timeout period. It is a voltage detector (not a µP supervisory circuit), so its output asserts immediately when VCC falls below VTH− and de-asserts immediately when VCC rises above VTH+. In contrast, MAX6464–MAX6466 variants provide a minimum 150ms timeout - a key functional distinction confirmed in the Selector Guide and Functional Diagram.
What is the output configuration of MAX6462XR16+T?
The MAX6462XR16+T features a push-pull output with active-high logic polarity. When VCC ≥ VTH+, the OUT pin is driven LOW; when VCC ≤ VTH−, OUT is driven HIGH. This eliminates the need for external pull-up resistors and allows direct interfacing with standard CMOS/TTL inputs - unlike MAX6461 (active-low push-pull) or MAX6463 (active-low open-drain) variants.
Can MAX6462XR16+T operate below 1.6V?
Yes, the MAX6462XR16+T operates down to 1.2V supply voltage per Absolute Maximum Ratings and Electrical Characteristics tables. While its threshold is fixed at 1.6V, the device remains functional and draws only 1.0µA at 1.2V - enabling reliable detection of deep brownout conditions before complete system failure, though output drive strength decreases below 1.8V.
Is MAX6462XR16+T pin-compatible with other MAX646x variants in SC70-3?
Yes, all MAX6461–MAX6466 SC70-3 variants (e.g., MAX6461XR16+T, MAX6463XR16+T) share identical pinout: Pin 1 = OUT, Pin 2 = GND, Pin 3 = VCC. However, output polarity and type differ - MAX6462XR16+T is active-high push-pull, while MAX6461XR16+T is active-low push-pull and MAX6463XR16+T is active-low open-drain - requiring firmware or schematic review before substitution.
