Analog Devices Inc./Maxim Integrated MAX6896PALT+

Overview

MAX6896PALT+ from Maxim Integrated is an ultra-small, low-power supervisory circuit with active-low enable and active-low push-pull 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, features 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 engineers reviewing the MAX6896PALT+ datasheet, MAX6896PALT+ pinout, MAX6896PALT+ application, or MAX6896PALT+ equivalent, this page delivers verified technical context, real-world timing behavior, package-specific layout guidance, and validated alternative options for automotive, medical, and industrial embedded sequencing designs.

Technical Context

The MAX6896PALT+ 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 down to 0.5V using external resistors, with 5mV hysteresis for noise immunity.

It uses a push-pull output referenced to VCC, delivering VOL ≤ 0.4V at 1mA sink current and VOH ≥ 0.8×VCC at 800µA source current. The device integrates undervoltage lockout (UVLO at 1.20–1.35V) and supports cascaded sequencing via its CDELAY pin, though delay is fixed-not capacitor-programmable-for enable-triggered transitions.

Key Specifications

FAQ

What is the exact enable-to-output propagation delay for MAX6896PALT+?

The MAX6896PALT+ has a guaranteed 150ns typical propagation delay from ENABLE going low to OUT transitioning low. This fixed delay is intrinsic to the P-version architecture and does not require external capacitors - enabling predictable, jitter-free sequencing in time-critical applications like automotive ADAS modules.

Can MAX6896PALT+ monitor a 1.2V supply rail?

Yes, MAX6896PALT+ can accurately monitor a 1.2V rail using an external resistive divider. With its 0.5V internal threshold and ±1.8% accuracy over –40°C to +125°C, a simple two-resistor network (e.g., R1 = 1.4MΩ, R2 = 1MΩ) sets the trip point precisely at 1.2V while maintaining low quiescent current due to ±15nA IN leakage.

Is the CDELAY pin used in MAX6896PALT+?

No - the CDELAY pin is not functional for timing in MAX6896PALT+. Unlike A-versions, the P-version uses fixed 150ns enable propagation delay. Datasheet recommends connecting CDELAY directly to GND to avoid floating node issues and ensure robust operation in noisy environments.

Does MAX6896PALT+ require an external pull-up resistor on the OUT pin?

No. MAX6896PALT+ features an active-low push-pull output, meaning it actively drives OUT low and high-impedance (not open-drain). No external pull-up is needed - simplifying design and improving noise immunity compared to open-drain alternatives like MAX6898PALT+.

What is the maximum sink current capability of MAX6896PALT+'s OUT pin?

MAX6896PALT+ guarantees VOL ≤ 0.4V at ISINK = 1mA when VCC ≥ 4.5V, and ≤ 0.3V at ISINK = 90µA for lower supply voltages. This allows direct interfacing with standard CMOS/TTL reset inputs without level-shifting, supporting robust reset assertion across its full 1.5V–5.5V operating range.
