Analog Devices Inc./Maxim Integrated MAX6896PAZT+T

Overview

MAX6896PAZT+T from Maxim Integrated is an ultra-small, low-power, adjustable-voltage supervisory circuit with active-low enable and active-low push-pull output, designed for power-supply sequencing and reset control in automotive and industrial systems. It monitors input voltages down to 0.5V with ±1.8% threshold accuracy over temperature, supports 1.5V–5.5V supply, features 150ns enable-to-output propagation delay, and operates across –40°C to +125°C.

For engineers reviewing the MAX6896PAZT+T datasheet, MAX6896PAZT+T pinout, MAX6896PAZT+T application, or MAX6896PAZT+T equivalent, key selection considerations include its fixed 150ns enable propagation delay (P-version), active-low logic interface, push-pull output drive capability, and qualification for automotive-grade thermal and reliability requirements.

Technical Context

The MAX6896PAZT+T implements a fixed-delay supervisory architecture: when VIN rises above 0.5V and ENABLE is asserted (low), the output asserts (OUT = low) after a guaranteed 150ns propagation delay - not capacitor-adjustable. Its high-impedance IN input (±15nA leakage) enables precise threshold setting via external resistive dividers, while the push-pull output drives loads directly without external pullups.

This device belongs to the MAX6895–MAX6899 family's P-version subgroup, distinguishing itself from A-versions by eliminating capacitor-programmable timing on the enable path. It shares the same 6-pin thin SOT23 package, 10µA typical supply current, and –40°C to +125°C operating range as other family members but delivers deterministic timing critical for synchronized power-up sequences.

Key Specifications

Pinout & Package

FAQ

What is the enable-to-output propagation delay of the MAX6896PAZT+T?

The MAX6896PAZT+T has a guaranteed 150ns typical propagation delay from ENABLE assertion (low) to OUT assertion (low). This fixed delay is inherent to the P-version architecture and does not require external capacitors - ensuring consistent, temperature-stable timing for critical power sequencing events in the MAX6896PAZT+T.

Does the MAX6896PAZT+T require an external capacitor on the CDELAY pin?

No, the MAX6896PAZT+T is a P-version device with fixed 150ns enable propagation delay; the CDELAY pin is unused and internally bypassed. Unlike A-versions, no external capacitor is needed - simplifying design, reducing BOM count, and eliminating capacitor-related timing drift in the MAX6896PAZT+T.

What output drive capability does the MAX6896PAZT+T provide?

The MAX6896PAZT+T features an active-low push-pull output capable of sinking up to 1mA at VCC ≥ 4.5V (VOL ≤ 0.4V) and sourcing sufficient current to reach ≥0.8×VCC when deasserted. This eliminates external pullup resistors and ensures robust interfacing with standard logic inputs in the MAX6896PAZT+T.

Is the MAX6896PAZT+T qualified for automotive applications?

While the MAX6896PAZT+T is not explicitly AEC-Q100 qualified (only MAX6896AAZT/V+T and MAX6896PAZT/V+T carry that designation), it shares the same die, package, and –40°C to +125°C full-temperature specification as qualified variants - making it suitable for non-certified automotive subsystems where full qualification is not mandated in the MAX6896PAZT+T.

How is the input threshold set on the MAX6896PAZT+T?

The MAX6896PAZT+T uses an internal 0.5V reference; the IN pin connects to the center tap of an external resistive divider across the monitored voltage rail. With ±15nA max input leakage, high-value resistors (e.g., 1MΩ) can be used to minimize current draw while maintaining threshold accuracy - a key design feature of the MAX6896PAZT+T.
