Analog Devices Inc./Maxim Integrated MAX16132F33G/V+T

Overview

MAX16132F33G/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 ±1% accurate undervoltage/overvoltage window faults, features active-low open-drain reset outputs with 560ms factory-set timeout, and operates across -40°C to +125°C in an 8-pin SOT23 package.

For engineers reviewing the MAX16132F33G/V+T datasheet, MAX16132F33G/V+T pinout, MAX16132F33G/V+T application, or MAX16132F33G/V+T equivalent, this device supports precise multivoltage monitoring in safety-critical automotive electronics where functional safety compliance, transient immunity, and guaranteed reset logic state down to VDD = 1.07V are essential.

Technical Context

The MAX16132F33G/V+T implements a quad-input window comparator architecture with independent threshold programming per input: IN1 = 3.300V, IN2 = 1.800V, IN3 = 1.200V, IN4 = 1.000V (per Selector Guide suffix G). Each input uses factory-trimmed ±7% tolerance with 0.25% hysteresis, enabling tight fault detection windows while rejecting short transients.

It delivers dual active-low open-drain reset outputs (RESET1, RESET2), where RESET1 asserts if IN1 or IN2 falls outside its window, and RESET2 asserts if IN3 or IN4 falls outside its window. All resets share the same 560ms minimum timeout period and require external pull-up resistors.

FAQ

What is the exact input voltage configuration for MAX16132F33G/V+T?

The MAX16132F33G/V+T is configured for quad-input supervision with nominal voltages of IN1 = 3.300V, IN2 = 1.800V, IN3 = 1.200V, and IN4 = 1.000V, as defined by the "G" suffix in the ordering code. Each input uses ±7% factory-programmed tolerance with 0.25% hysteresis, per Tables 4 and 8 in the datasheet.

Does MAX16132F33G/V+T support overvoltage detection on all four inputs?

Yes, MAX16132F33G/V+T performs full window supervision - both undervoltage and overvoltage detection - on all four inputs (IN1–IN4). The ±7% tolerance setting defines symmetric UV/OV thresholds relative to each nominal voltage, and the ±1% accuracy guarantee applies to both thresholds across temperature.

What is the reset timeout period for MAX16132F33G/V+T and how is it set?

The MAX16132F33G/V+T has a factory-set minimum reset timeout period of 560ms, indicated by the "T" suffix in the part number (Table 9). This timeout is fixed and shared across both RESET1 and RESET2 outputs; it begins when a fault is cleared and ends when the corresponding input(s) re-enter their valid window.

How does the dual-reset architecture of MAX16132F33G/V+T function?

MAX16132F33G/V+T uses grouped reset logic: RESET1 asserts if either IN1 or IN2 falls outside its programmed window, and RESET2 asserts if either IN3 or IN4 falls outside its window. This enables hierarchical fault response - e.g., isolating I/O domain faults (IN1/IN2) from core/memory domains (IN3/IN4) - without requiring external logic.

Is MAX16132F33G/V+T AEC-Q100 qualified and what grade does it meet?

Yes, MAX16132F33G/V+T carries the "/V" suffix indicating AEC-Q100 qualification for Grade 0 (-40°C to +125°C), verified per stress test requirements including HTOL, TCT, and ESD. This qualification supports deployment in automotive ADAS, body control modules, and other safety-relevant electronic control units.
