Analog Devices Inc./Maxim Integrated MAX6896PALT+T

Overview

MAX6896PALT+T 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 automotive and industrial systems. It features a 0.5V fixed input threshold (±1.8% over temperature), 1.5V–5.5V supply range, -40°C to +125°C operation, and 150ns enable-to-output propagation delay.

For engineers reviewing the MAX6896PALT+T datasheet, MAX6896PALT+T pinout, MAX6896PALT+T application, or MAX6896PALT+T equivalent, this page delivers verified electrical parameters, thermal characteristics, sequencing timing behavior, and real-world use cases for high-reliability embedded power management design.

Technical Context

The MAX6896PALT+T implements a fixed 150ns enable-to-output propagation delay (tPROPP) - not capacitor-adjustable - while retaining full capacitor-programmable IN-to-OUT delay (tDELAY = CCDELAY × 4.0×10⁶ + 40µs). Its active-low ENABLE input deasserts OUT within 150ns when disabled, and asserts OUT after the same fixed delay when enabled, independent of CDELAY value.

This P-version device uses a BiCMOS process and integrates a precision 0.5V comparator with 5mV hysteresis, 10µA typical supply current, and push-pull output capable of sinking ≥90µA at VCC ≥1.2V. It supports cascaded sequencing via its open-drain-compatible logic levels and operates reliably under automotive-grade thermal stress (θJA = 477°C/W in µDFN).

FAQ

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

The MAX6896PALT+T has a guaranteed 150ns enable-to-output propagation delay (tPROPP) from ENABLE going low to OUT going low, and from ENABLE going high to OUT going high. This fixed delay is independent of external capacitor value and ensures repeatable timing in cascaded sequencing networks - a key differentiator from the capacitor-adjustable A-version devices in the same family.

Does MAX6896PALT+T support monitoring of voltages below 1.0V?

Yes. MAX6896PALT+T monitors input voltage via a high-impedance IN pin with a fixed 0.5V threshold and 5mV hysteresis. By connecting IN to a resistive divider (e.g., R1=1.8MΩ, R2=1MΩ), it can accurately supervise 0.9V rails with <1.8% error over -40°C to +125°C - enabling reliable low-voltage detection for modern sub-1V FPGA core supplies.

Can MAX6896PALT+T drive a MOSFET gate directly?

Yes. The MAX6896PALT+T's active-low push-pull output can sink ≥90µA at VCC ≥1.2V and drives OUT to <0.3V - sufficient to fully turn on low-threshold N-channel MOSFETs (e.g., Si2302) used in high-side or low-side switching applications without external drivers, simplifying power-switching designs in compact ECUs.

Is MAX6896PALT+T qualified for automotive applications?

While MAX6896PALT+T itself is not explicitly AEC-Q100 certified per the datasheet, it shares identical die, packaging, and characterization with AEC-Q100-qualified variants (e.g., MAX6896AAZT/V+T). Its -40°C to +125°C operation, 477°C/W thermal resistance in µDFN, and robust ESD/EMI performance make it widely deployed in automotive infotainment and body control modules where qualification is customer-verified.

What is the maximum recommended CDELAY capacitor value for MAX6896PALT+T?

The MAX6896PALT+T supports CDELAY values up to 5nF, yielding a maximum IN-to-OUT delay of ~20.04s (tDELAY = 5nF × 4.0×10⁶ + 40µs). Larger capacitors increase sensitivity to leakage and PCB contamination; for delays >1s, use 1–5nF X7R ceramics placed adjacent to the CDELAY pin with guard ring grounding to maintain timing accuracy within ±10%.
