Analog Devices Inc./Maxim Integrated MAX16132H10B+T

Overview

MAX16132H10B+T from Analog Devices is a precision quad-voltage microprocessor supervisor IC designed for automotive ADAS systems. It monitors four independent supply rails (1.0V–5.0V nominal) with ±1% threshold accuracy over temperature, detects undervoltage/overvoltage window faults, and delivers active-low open-drain reset outputs with factory-programmable 560ms timeout. Its SOT23-8 package supports operation from –40°C to +125°C and AEC-Q100 qualification.

For engineers reviewing the MAX16132H10B+T datasheet, MAX16132H10B+T pinout, MAX16132H10B+T application, or MAX16132H10B+T equivalent, key selection criteria include quad-input window monitoring capability, ±1% threshold accuracy across automotive temperature range, 560ms factory-set reset timeout, and compatibility with multivoltage ASICs requiring functional safety support.

Technical Context

The MAX16132H10B+T implements a quad-input window comparator architecture with independent input tolerance programming (±4% to ±11%) and hysteresis options (0.25% or 0.50%). Each input uses a precision voltage reference and factory-trimmed UV/OV thresholds referenced to its nominal voltage setting.

All four inputs share a single 560ms reset timeout period (suffix "T"), and reset outputs remain asserted until all monitored voltages return within their respective windows. The device guarantees correct logic state down to VDD = 1.07V and features low 15μA quiescent current.

Key Specifications

FAQ

What is the nominal input voltage configuration for MAX16132H10B+T?

The "H10B" suffix indicates this variant is configured for 1.8V nominal voltage on IN1 and IN2, 1.2V on IN3, and 1.0V on IN4 (per Table 4, suffix H), with ±4% tolerance and 0.25% hysteresis (per Table 8, suffix B). All thresholds are factory-programmed and non-adjustable in-circuit. MAX16132H10B+T operates with these fixed settings across its full temperature range.

Does MAX16132H10B+T support independent reset outputs for each input?

No. MAX16132H10B+T follows the MAX16135 architecture: RESET1 asserts when either IN1 or IN2 falls outside its window, and RESET2 asserts when either IN3 or IN4 falls outside its window. It does not provide four independent reset outputs like MAX16134. This dual-reset structure reduces pin count while maintaining fault isolation between input pairs.

What is the guaranteed minimum reset timeout period for MAX16132H10B+T?

The "T" suffix specifies a factory-set minimum reset timeout of 560ms. This value is guaranteed over –40°C to +125°C and applies identically to both RESET1 and RESET2 outputs. The timeout begins when VDD exceeds UVLO (1.35V) and ends only after all monitored inputs return within their respective UV/OV windows for the full duration.

Is MAX16132H10B+T AEC-Q100 qualified?

Yes. MAX16132H10B+T is specified for the automotive temperature range (–40°C to +125°C) and carries AEC-Q100 qualification per the MAX16132–MAX16135 family datasheet. It meets stress test requirements for Grade 0 devices, supporting deployment in ADAS, body control, and powertrain modules where reliability under thermal cycling and vibration is mandatory.

How does the open-drain reset output of MAX16132H10B+T interface with a microcontroller?

Both RESET1 and RESET2 are active-low, open-drain outputs requiring external pull-up resistors to a valid logic voltage (e.g., VDD or another rail). When asserted, they sink current to ground; when deasserted, they present high impedance. This allows wired-OR connection of multiple reset sources and compatibility with MCUs having either active-low or active-high reset inputs via simple inversion logic.
