Analog Devices Inc./Maxim Integrated MAX16132H10B/V+

Overview

MAX16132H10B/V+ from Analog Devices is a quad-voltage microprocessor supervisor IC designed for automotive ADAS systems, monitoring four independent supply rails (IN1–IN4) for undervoltage and overvoltage faults within ±1% threshold accuracy over -40°C to +125°C. It features factory-programmed 1.0V nominal input voltage per channel, ±4% window tolerance, 0.25% hysteresis, and a 1ms reset timeout period. Its active-low open-drain reset outputs (RESET1, RESET2) support dual-zone fault response in multivoltage ASICs.

For engineers reviewing the MAX16132H10B/V+ datasheet, MAX16132H10B/V+ pinout, MAX16132H10B/V+ application, or MAX16132H10B/V+ equivalent, key selection criteria include quad-input window supervision with AEC-Q100 qualification, guaranteed reset logic state down to VDD = 1.07V, immunity to short monitored-supply transients, and compatibility with functional safety architectures requiring precise voltage fault detection.

Technical Context

The MAX16132H10B/V+ implements a quad-input window comparator architecture with independent UV/OV thresholds per channel, where each input's fault detection is based on a factory-trimmed ±4% tolerance around its 1.0V nominal setting. All four inputs share identical hysteresis (0.25%) and are immune to transients shorter than the propagation delay (15µs).

Its dual active-low open-drain reset outputs-RESET1 (asserted when IN1 or IN2 falls outside window) and RESET2 (asserted when IN3 or IN4 falls outside window)-are synchronized to the same 1ms factory-set timeout period and require external pullup resistors. The device operates from 1.71V to 5.5V VDD and guarantees correct output logic state as long as VDD > 1.07V.

FAQ

What is the nominal input voltage configuration for MAX16132H10B/V+?

The MAX16132H10B/V+ is factory-configured for 1.0V nominal input voltage on all four monitoring inputs (IN1–IN4), as indicated by the "H10" suffix. This sets the undervoltage threshold at 0.96V and overvoltage threshold at 1.04V using ±4% tolerance. Each input maintains ±1% accuracy over -40°C to +125°C, and the device requires no external programming to operate at this configuration. MAX16132H10B/V+ is delivered fully calibrated and ready for use in 1.0V rail supervision.

How does the dual-reset architecture of MAX16132H10B/V+ function in fault isolation?

MAX16132H10B/V+ uses a grouped dual-reset architecture: RESET1 asserts when either IN1 or IN2 falls outside its 0.96V–1.04V window, while RESET2 asserts when either IN3 or IN4 falls outside the same window. This enables logical OR-based fault grouping per output, allowing system designers to isolate two independent power domains (e.g., sensor cluster vs. processing unit) with minimal pin count. Both outputs share the same 1ms timeout and require individual pullup resistors. MAX16132H10B/V+ guarantees correct reset state down to VDD = 1.07V.

Is MAX16132H10B/V+ qualified for automotive applications?

Yes, MAX16132H10B/V+ is AEC-Q100 qualified for Grade 0 operation (-40°C to +125°C ambient), with full characterization across temperature, voltage, and lifetime stress tests. It meets automotive reliability standards including HTOL, TC, and UHAST, and is specified for use in ADAS, infotainment, and body electronics. The /V+ suffix confirms tape-and-reel packaging with wettable flanks for automotive-grade solder-joint inspection. MAX16132H10B/V+ supports functional safety development per ISO 26262 ASIL-B requirements due to its ±1% threshold accuracy and guaranteed reset behavior.

What is the reset timeout period for MAX16132H10B/V+ and how is it set?

The reset timeout period for MAX16132H10B/V+ is factory-set to 1ms, denoted by the "B" in the part number suffix (per Table 9 in the datasheet). This timeout applies identically to both RESET1 and RESET2 outputs and begins when any monitored input re-enters its valid window. The device offers 23 standard timeout options ranging from 20µs to 1200ms, but MAX16132H10B/V+ is permanently configured for 1ms - no external components or registers are used to adjust it. MAX16132H10B/V+ maintains reset assertion for the full 1ms duration after fault clearance, ensuring robust processor initialization.

Does MAX16132H10B/V+ support undervoltage-only or overvoltage-only monitoring?

No, MAX16132H10B/V+ implements fixed window supervision only - each input (IN1–IN4) monitors both undervoltage and overvoltage conditions relative to its 1.0V nominal setting. The ±4% tolerance defines a symmetric window (0.96V–1.04V), and the device asserts reset if the input falls below UV threshold or rises above OV threshold. There is no mode or configuration to disable one side of the window. This window architecture is intrinsic to the MAX16132H10B/V+ design and ensures comprehensive supply integrity checking. MAX16132H10B/V+ does not support single-threshold (UV-only or OV-only) operation.
