Product details
Overview
MAX6898PALT from Maxim Integrated is an ultra-small, low-power supervisory circuit with active-low enable and active-low open-drain output, designed for precise power-supply sequencing and reset control in space-constrained systems. It monitors input voltages down to 0.5V via external resistive divider, provides 150ns enable-to-output propagation delay, operates from 1.5V to 5.5V supply, and is fully specified over –40°C to +125°C for automotive and industrial applications.
For engineers reviewing the MAX6898PALT datasheet, MAX6898PALT pinout, MAX6898PALT application, or MAX6898PALT equivalent, this page delivers verified technical context, exact pin functions, real-world sequencing use cases, and validated alternative options for voltage monitoring and enable-controlled power sequencing.
Technical Context
The MAX6898PALT implements a fixed 150ns propagation delay from ENABLE assertion (low) to OUT assertion (low), distinguishing it from capacitor-adjustable A-versions. Its high-impedance IN input (±15nA leakage) enables accurate threshold setting via external resistor dividers, with 0.5V rising threshold and 5mV hysteresis.
It features an open-drain output rated for 28V pullup voltage, supporting level-shifting across disparate supply domains, and integrates undervoltage lockout (UVLO) at 1.20V–1.35V to ensure reliable operation during brownout conditions. The device draws only 10µA typical supply current, enabling battery-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - powers directly from common logic rails without LDO overhead |
| IN Threshold Voltage | 0.491V to 0.509V - enables precise monitoring of sub-1V rails (e.g., 1.2V, 1.8V) with ±1.8% accuracy over temperature |
| ENABLE Input Logic | Active-low - asserts output when ENABLE falls below 0.4V, deasserts when above 1.4V |
| OUT Type & Rating | Active-low open-drain, 28V tolerant - supports external pullup to higher voltage domains (e.g., 12V, 24V) for system-level enable signaling |
| Enable-to-Output Delay | 150ns typ - deterministic, fixed timing for fast enable-controlled sequencing without capacitor tuning |
| Supply Current | 10µA typ - minimizes quiescent power in always-on monitoring paths |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and medical equipment environments |
Pinout & Package
MAX6898PALT is housed in an ultra-small 6-pin µDFN package (1.5mm × 1.0mm × 0.8mm, package code L611-1), optimized for high-density PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ENABLE | Active-low logic-enable input | Drives output low when pulled ≤0.4V; deasserts output high when ≥1.4V - enables immediate system-level control independent of monitored voltage |
| 2 - GND | Ground reference | Common return path for internal circuitry and external CDELAY capacitor; must be low-impedance for stable timing |
| 3 - IN | High-impedance monitor input | Accepts voltage from external resistive divider; triggers on 0.5V rising edge with 5mV hysteresis to reject noise-induced false trips |
| 4 - OUT | Active-low open-drain output | Sinks current when asserted (low); requires external pullup resistor - enables bidirectional voltage domain interfacing up to 28V |
| 5 - CDELAY | Delay capacitor connection | Unused in P-version - internally bypassed; no external capacitor required for timing (unlike A-versions) |
| 6 - VCC | Supply voltage input | Accepts 1.5V–5.5V; requires local 0.1µF ceramic decoupling to GND for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 150ns enable propagation delay | Eliminates timing uncertainty and capacitor tolerance drift in critical enable-chain sequencing |
| 28V-tolerant open-drain output | Allows direct interface to higher-voltage system buses (e.g., 12V/24V enable lines) without level-shifters |
| 0.5V precision monitor threshold | Supports accurate supervision of modern low-voltage rails (1.2V, 1.8V, 2.5V) using standard resistor values |
| 10µA typical supply current | Enables continuous monitoring in battery-backed or energy-harvesting systems without significant drain |
| –40°C to +125°C operation | Validated for automotive engine control units, industrial PLCs, and medical diagnostic equipment |
Applications

| Automotive Body Control Module | Industrial Sensor Node Power Management |
Use Scenario: Enabling auxiliary subsystems (e.g., LIN transceivers, LED drivers) only after main 5V bus stabilizes and ignition signal is valid. IC Role / Device Role / Timing Role: Dual-condition supervisor monitoring both battery-derived rail and ignition switch status via IN and ENABLE inputs. Use Value: Ensures fail-safe operation by requiring both power integrity and system command before enabling safety-critical loads. |
Use Scenario: Managing power to wireless sensor ICs (e.g., temperature, humidity) in battery-operated IIoT nodes with intermittent wake cycles. IC Role / Device Role / Timing Role: Low-quiescent-current sequencer that gates sensor power using open-drain output tied to load switch gate. Use Value: Reduces standby current to <15µA total system draw while maintaining precise voltage qualification before activation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-monitoring and sequencing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6898AALT+T | Capacitor-adjustable enable-to-output delay (190ms max) vs. fixed 150ns | Suitable where variable sequencing timing is needed across product variants | Select MAX6898AALT+T if delay tuning per board revision is required; MAX6898PALT is preferred for production stability and BOM simplification |
| TPS3808G15DBVR | Active-low push-pull output (not open-drain), 200ms max adjustable delay, 1.5V–6.5V supply | Lacks 28V-tolerant output; limited to same-domain signaling | Choose TPS3808G15DBVR only when open-drain capability is unnecessary and TI ecosystem alignment is prioritized |
Compared with MAX6898AALT+T and TPS3808G15DBVR, MAX6898PALT uniquely combines deterministic 150ns enable response, 28V-tolerant open-drain output, and ultra-low 10µA supply current in a 1.5mm × 1.0mm footprint - making it optimal for compact, multi-rail automotive and industrial sequencers requiring robust cross-domain control.

FAQ
What is the enable-to-output propagation delay of the MAX6898PALT?
The MAX6898PALT has a fixed 150ns typical propagation delay from ENABLE assertion (low) to OUT assertion (low). This deterministic timing eliminates capacitor tolerance and temperature drift issues found in adjustable-delay versions like the MAX6898AALT+T, making MAX6898PALT ideal for tightly synchronized enable chains in automotive and industrial systems.
Does the MAX6898PALT require an external capacitor on the CDELAY pin?
No, the MAX6898PALT does not require an external capacitor on the CDELAY pin. As a "P" version device, it uses a fixed 150ns enable-to-output delay instead of capacitor-programmable timing. The CDELAY pin is internally bypassed; leaving it unconnected or grounded poses no risk, unlike A-version devices which rely on CCDELAY for delay setting.
What is the maximum allowable voltage on the MAX6898PALT OUT pin?
The MAX6898PALT OUT pin is an active-low open-drain output rated for up to 28V. This allows the output to be pulled up to higher voltage domains (e.g., 12V, 24V, or 28V) independent of the VCC supply (1.5V–5.5V), enabling flexible system-level enable signaling across mixed-voltage architectures without additional level-shifting circuitry.
Can the MAX6898PALT monitor a 1.2V supply rail?
Yes, the MAX6898PALT can accurately monitor a 1.2V rail using an external resistive divider connected to the IN pin. With its precise 0.5V threshold (±1.8% over temperature) and ±15nA input leakage, a simple two-resistor network (e.g., R1 = 1.4MΩ, R2 = 1MΩ) scales 1.2V down to 0.5V at IN, ensuring reliable detection without loading the source rail.
How does the MAX6898PALT behave during VCC brownout?
During VCC brownout, the MAX6898PALT incorporates undervoltage lockout (UVLO) that deasserts the output when VCC falls below 1.20V–1.35V. Below 1.2V, output state is undefined - ensuring downstream circuits are disabled before internal logic becomes unreliable. This behavior protects system integrity during power collapse, a key requirement in automotive and medical applications.
