Analog Devices Inc./Maxim Integrated MAX16132B33F/V+T

Overview

MAX16132B33F/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 at 3.3V, 1.0V, 1.0V, and 3.3V per ordering suffix F), detects undervoltage/overvoltage faults within ±1% threshold accuracy over -40°C to +125°C, features dual active-low open-drain reset outputs (RESET1/RESET2), and provides factory-programmed 560ms minimum reset timeout.

For engineers reviewing the MAX16132B33F/V+T datasheet, MAX16132B33F/V+T pinout, MAX16132B33F/V+T application, or MAX16132B33F/V+T equivalent, this device delivers precision window monitoring for multivoltage ASICs in safety-critical automotive environments where guaranteed logic state down to VDD = 1.07V and AEC-Q100 qualification are essential.

Technical Context

The MAX16132B33F/V+T implements a quad-input window supervision architecture with two independent reset channels: RESET1 asserts when IN1 or IN2 falls outside its programmed window, RESET2 asserts when IN3 or IN4 falls outside its window. Each input uses factory-trimmed ±1% accurate comparators with programmable tolerance (±4% to ±11%) and hysteresis (0.25% or 0.50%).

All four inputs share identical electrical characteristics: 1.71V–5.5V operating supply, 15μA typical supply current, and immunity to short monitored-supply transients. The device guarantees correct reset output logic state as long as VDD remains above 1.07V, enabling robust power sequencing in automotive ECUs.

FAQ

What is the nominal input voltage configuration for MAX16132B33F/V+T?

The MAX16132B33F/V+T is configured for quad-input monitoring with nominal voltages of 3.3V (IN1), 1.0V (IN2), 1.0V (IN3), and 3.3V (IN4), as indicated by the "F" suffix in the ordering code per Analog Devices' Selector Guide. This matches the dual-pair architecture where RESET1 covers IN1/IN2 and RESET2 covers IN3/IN4.

Does MAX16132B33F/V+T support window monitoring on all four inputs?

Yes, MAX16132B33F/V+T performs true window monitoring (both undervoltage and overvoltage detection) on each of its four inputs. The device uses factory-programmed tolerance settings to define upper and lower thresholds relative to each nominal voltage, with ±1% accuracy maintained over the full -40°C to +125°C range.

What is the reset timeout period for MAX16132B33F/V+T?

The MAX16132B33F/V+T has a factory-programmed minimum reset timeout period of 560ms, designated by the "T" suffix in the part number per Table 9 of the datasheet. This timeout applies identically to both RESET1 and RESET2 outputs and begins after monitored voltages return within their respective window thresholds.

Is MAX16132B33F/V+T AEC-Q100 qualified?

Yes, MAX16132B33F/V+T carries the "/V" suffix indicating AEC-Q100 qualification for automotive applications. It is rated for the full -40°C to +125°C temperature range and tested to meet stress test requirements for Grade 0 (−40°C to +150°C junction) per the AEC-Q100 standard.

How does the dual-reset architecture of MAX16132B33F/V+T improve system reliability?

The dual-reset architecture of MAX16132B33F/V+T improves system reliability by grouping logically related power domains: RESET1 asserts if either IN1 (3.3V) or IN2 (1.0V) faults, while RESET2 asserts if either IN3 (1.0V) or IN4 (3.3V) faults. This mirrors real-world SoC power domain dependencies and prevents partial initialization that could occur with independent single-channel supervisors.
