Analog Devices Inc./Maxim Integrated MAX16132G04D/V+T

Overview

MAX16132G04D/V+T from Analog Devices is a quad-voltage microprocessor supervisor IC designed for automotive ADAS systems. It monitors four independent supply rails (IN1–IN4) for undervoltage and overvoltage faults within ±1% threshold accuracy over −40°C to +125°C, features factory-programmable 1.24V nominal input on IN1, ±5% tolerance window, 0.25% hysteresis, and 3ms reset timeout period. Its open-drain active-low reset outputs ensure reliable power-on reset sequencing in multivoltage ASICs.

For engineers reviewing the MAX16132G04D/V+T datasheet, MAX16132G04D/V+T pinout, MAX16132G04D/V+T application, or MAX16132G04D/V+T equivalent, key selection criteria include quad-input window monitoring capability, AEC-Q100 qualification (/V suffix), SOT23-8 package compatibility, and guaranteed reset assertion down to VDD = 1.07V - critical for functional safety in automotive power management.

Technical Context

The MAX16132G04D/V+T implements dual independent reset outputs (RESET1, RESET2), where RESET1 asserts when either IN1 or IN2 falls outside its programmed window, and RESET2 asserts when either IN3 or IN4 falls outside its window. All inputs support factory-trimmed nominal voltages from 1.0V to 5.0V and ±4% to ±11% tolerance with 0.25% or 0.50% hysteresis.

It uses internal voltage references and precision comparators to achieve ±1% threshold accuracy across temperature, with immunity to short monitored-supply transients. The device shares one factory-set reset timeout period (3ms per Table 9 suffix 'D') across all outputs and guarantees correct logic state for VDD ≥ 1.07V.

FAQ

What is the nominal input voltage programmed for IN1 on MAX16132G04D/V+T?

The '04' suffix in MAX16132G04D/V+T specifies a factory-programmed nominal input voltage of 1.240V for IN1, as defined in Table 1 of the datasheet. This enables precise supervision of 1.2V core supplies with ±5% tolerance (suffix 'D'), yielding UV threshold = 1.178V and OV threshold = 1.302V. The value is laser-trimmed at wafer test and not user-adjustable.

Does MAX16132G04D/V+T support independent reset timeout periods per channel?

No. MAX16132G04D/V+T uses a single factory-set reset timeout period shared across all outputs - 3ms minimum for suffix 'D'. The device does not support per-channel timeout configuration. This simplifies timing validation in automotive systems where synchronized reset release across multiple domains is required for deterministic boot behavior.

How is the /V suffix in MAX16132G04D/V+T validated for automotive use?

The /V suffix in MAX16132G04D/V+T denotes AEC-Q100 qualification, confirmed through standardized stress tests including HTOL (high-temperature operating life), TC (temperature cycling), and AC/DC parametric verification across −40°C to +125°C. This qualification applies to the full MAX16132–MAX16135 family and is documented in Analog Devices' official AEC-Q100 certificate for this part number.

Can unused inputs on MAX16132G04D/V+T be left floating?

No. Unused inputs on MAX16132G04D/V+T must be connected to their respective nominal voltage (e.g., 1.24V for IN1 if used, or appropriate voltage per configuration) to prevent false resets. Floating inputs may cause comparator instability due to leakage currents and noise coupling, violating the device's specified immunity to short transients. The datasheet explicitly requires tied inputs for reliable operation.

What is the maximum supply voltage and minimum operating VDD for MAX16132G04D/V+T?

MAX16132G04D/V+T operates from VDD = 1.71V to 5.5V, with absolute maximum rating of 6V. Crucially, its reset outputs guarantee correct logic state (active-low asserted) down to VDD = 1.07V - below the operational range - ensuring fail-safe reset assertion during brownout conditions before the device ceases functional operation.
