Product details
Overview
MAX6895PALT+T from Maxim Integrated is an ultra-small, low-power voltage supervisory circuit with adjustable threshold monitoring and fixed 150ns enable-to-output propagation delay. It features active-high enable input, active-high push-pull output, 0.5V precision input threshold (±1.8% over temperature), 1.5V–5.5V supply range, and operates across –40°C to +125°C. It is used in power-supply sequencing and reset control for industrial embedded systems.
For engineers reviewing the MAX6895PALT+T datasheet, MAX6895PALT+T pinout, MAX6895PALT+T application, or MAX6895PALT+T equivalent, key selection criteria include its fixed 150ns enable propagation delay (vs. capacitor-adjustable versions), push-pull output drive capability, µDFN-6 package footprint, and compatibility with low-voltage rail monitoring down to 0.5V via external resistor divider.
Technical Context
The MAX6895PALT+T implements a high-impedance monitor input (IN) with fixed 0.5V rising threshold and 5mV hysteresis, enabling precise low-voltage detection using external resistive dividers. Its ENABLE pin is active-high and asserts the output after a guaranteed 150ns propagation delay - not capacitor-programmable like A-version devices.
Output behavior is deterministic: OUT goes high when both IN > 0.5V and ENABLE = high, and deasserts to low within 16µs when IN falls below 0.495V or ENABLE goes low. The push-pull output drives up to ±20mA and supports VCC-referenced logic levels with VOH ≥ 0.8×VCC at 500µA source current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - powers from single Li-ion cell up to 5V logic rails without external regulation. |
| Input Threshold Voltage | 0.5V ±1.8% over –40°C to +125°C - enables accurate monitoring of sub-1V rails (e.g., 1.2V, 1.8V) with external divider. |
| Enable-to-Output Delay | 150ns typical - provides deterministic, jitter-free assertion timing independent of external capacitor tolerance or temperature drift. |
| Supply Current | 10µA typical at 3.3V - minimizes quiescent power in always-on monitoring paths for battery-backed systems. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and harsh-environment embedded applications. |
| Output Type | Active-high push-pull - eliminates need for external pull-up resistor and ensures fast, rail-to-rail logic transitions. |
| Package | 6-pin µDFN (1.0mm × 1.5mm) - supports high-density PCB layouts with minimal board area and thermal resistance of 477°C/W (θJA). |
Pinout & Package
MAX6895PALT+T is housed in a 6-pin ultra-thin µDFN package (1.0mm × 1.5mm, 0.5mm pitch), optimized for space-constrained applications. Thermal resistance θJA = 477°C/W (JEDEC 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ENABLE | Active-high logic-enable input | Drives output high within 150ns when asserted; forces output low immediately when deasserted - enables synchronous system-level control. |
| 2 - GND | Ground reference | Common return path for internal biasing and output stage; must be low-impedance to ensure noise immunity and accurate threshold operation. |
| 3 - IN | High-impedance monitor input | Accepts divided-down voltage; 15nA max input leakage allows use of MΩ-range resistors without measurement error. |
| 4 - OUT | Active-high push-pull output | Drives high to VCC or low to GND; sinks/source up to ±20mA - directly interfaces with MCU reset inputs or MOSFET gate drivers. |
| 5 - CDELAY | Capacitor-adjustable delay node | Connected to external capacitor for IN-to-OUT delay; internal 250nA current source charges CCDELAY to 1.0V threshold - sets tDELAY = CCDELAY × 4.0×10⁶ + 40µs. |
| 6 - VCC | Power supply input | Accepts 1.5V–5.5V; requires local 0.1µF ceramic bypass to GND - UVLO activates below 1.2V to prevent undefined output states. |
Key Features
| Feature | Design Value |
|---|---|
| 150ns enable propagation delay | Guaranteed fixed timing eliminates capacitor tolerance and temperature drift - critical for deterministic reset sequencing in multi-rail systems. |
| 0.5V ±1.8% threshold over temperature | Enables accurate monitoring of low-voltage rails (e.g., 1.2V, 1.8V) with simple two-resistor divider - no calibration required across full industrial temp range. |
| Push-pull active-high output | Eliminates external pull-up resistor and reduces BOM count; delivers rail-to-rail logic levels compatible with 1.8V/3.3V/5V MCUs and FPGAs. |
| Ultra-low 10µA supply current | Extends battery life in always-on supervision circuits - suitable for energy-sensitive portable and IoT edge nodes. |
| –40°C to +125°C operation | Fully specified across extended temperature range - supports deployment in automotive engine control units and industrial motor drives without derating. |
Applications
| Power-Supply Sequencing | Microcontroller Reset Supervision |
|---|---|
Use Scenario: Controlling startup order of multiple DC-DC converters (e.g., 1.2V, 1.8V, 3.3V) in FPGA-based systems to prevent latch-up or back-powering. IC Role / Device Role / Timing Role: Voltage supervisor that monitors upstream rail and enables downstream regulator only after stable voltage is confirmed. Use Value: Prevents improper power-up sequence by asserting enable signal only after valid input voltage exceeds 0.5V and ENABLE is asserted - with deterministic 150ns response. | Use Scenario: Providing clean, glitch-free reset signal to ARM Cortex-M microcontrollers during brown-out or cold-start conditions. IC Role / Device Role / Timing Role: Precision reset generator that holds MCU in reset until main supply reaches safe operating voltage and remains asserted during enable window. Use Value: Ensures reliable boot by combining 0.5V threshold accuracy and 150ns enable delay - avoids premature release due to supply ripple or transient dips. |
| Overvoltage Protection Control | Low-Voltage Rail Monitoring |
Use Scenario: Detecting overvoltage on a 5V bus and disabling p-channel MOSFET switch within microseconds to protect downstream 3.3V logic. IC Role / Device Role / Timing Role: Fast-response supervisory circuit that triggers shutdown path when monitored voltage exceeds preset threshold via resistor divider. Use Value: Uses high-impedance IN input and 150ns enable delay to initiate protection action before damage occurs - compatible with high-side switch control. | Use Scenario: Monitoring battery voltage in a medical sensor node to trigger low-battery warning or graceful shutdown before 1.8V logic fails. IC Role / Device Role / Timing Role: Low-power voltage detector that asserts interrupt or control signal when battery drops below 2.0V (set via R1/R2 divider on IN pin). Use Value: Achieves <10µA quiescent current and ±1.8% threshold accuracy - extends operational time while maintaining precise undervoltage detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6895AALT+T | Capacitor-adjustable enable-to-output delay (vs. fixed 150ns); same pinout, threshold, and supply range. | Suitable where variable delay tuning is needed for system-specific timing margins or cascaded sequencing. | Select MAX6895AALT+T if delay must be programmable; MAX6895PALT+T preferred for deterministic, low-jitter timing. |
| TLV803EB25DBVR | Fixed 2.5V threshold (not adjustable), 350ms reset timeout, SOT-23-3 package, no enable input. | Limited to single-rail 2.5V monitoring; lacks sequencing capability and external enable control. | Choose TLV803EB25DBVR only for simple, cost-sensitive 2.5V reset - not a functional substitute for MAX6895PALT+T's adjustable threshold and enable-controlled sequencing. |
Compared with MAX6895AALT+T, MAX6895PALT+T trades delay flexibility for timing determinism and reduced component count (no CDELAY capacitor). Versus TLV803EB25DBVR, it offers full configurability for multi-rail systems but requires more design effort for resistor-divider setup and layout.

FAQ
What is the input threshold voltage of the MAX6895PALT+T and how accurate is it over temperature?
The MAX6895PALT+T has a fixed input threshold voltage of 0.5V with ±1.8% accuracy over the full –40°C to +125°C operating range. This specification is guaranteed by design and tested across temperature, enabling reliable low-voltage rail monitoring (e.g., 1.2V, 1.8V) using standard resistor dividers without recalibration.
Does the MAX6895PALT+T require an external capacitor for enable-to-output timing?
No, the MAX6895PALT+T does not require an external capacitor for enable-to-output timing. It features a fixed 150ns propagation delay from ENABLE assertion to OUT assertion - unlike the A-version (e.g., MAX6895AALT+T), which uses CDELAY for adjustable timing. The CDELAY pin remains functional for IN-to-OUT delay only.
What package type is used for the MAX6895PALT+T and what are its key mechanical dimensions?
The MAX6895PALT+T uses a 6-pin µDFN package measuring 1.0mm × 1.5mm with 0.5mm pitch. Its ultra-compact footprint supports high-density PCB layouts, and its thermal resistance (θJA = 477°C/W) is characterized per JEDEC JESD51-7 on a 4-layer board.
Can the MAX6895PALT+T monitor voltages below 1.0V, and how is the threshold set?
Yes, the MAX6895PALT+T can monitor voltages as low as 0.5V directly at the IN pin. To monitor higher voltages (e.g., 3.3V, 5V), connect a resistive divider between the rail and IN, selecting R1 and R2 such that the divided voltage equals 0.5V at the desired trip point - e.g., for 3.3V monitoring, R1/R2 ≈ 5.6.
What is the maximum sink/source current capability of the MAX6895PALT+T push-pull output?
The MAX6895PALT+T push-pull output supports ±20mA continuous current per pin. At 3.3V supply, it delivers VOH ≥ 2.64V at 500µA source current and VOL ≤ 0.3V at 90µA sink current - sufficient to directly drive MCU reset inputs, logic gates, or small MOSFET gates without buffering.
