Analog Devices Inc./Maxim Integrated MAX16132H10B/V+T

Overview

MAX16132H10B/V+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, ±4% to ±11% programmable window tolerance, and 560ms factory-set reset timeout. Its active-low open-drain reset outputs ensure reliable power-on reset sequencing in multivoltage ASICs.

For engineers reviewing the MAX16132H10B/V+T datasheet, MAX16132H10B/V+T pinout, MAX16132H10B/V+T application, or MAX16132H10B/V+T equivalent, this device delivers AEC-Q100 qualified supervision for safety-critical automotive voltage monitoring where precise undervoltage/overvoltage window detection and guaranteed logic state down to VDD = 1.07V are required.

Technical Context

The MAX16132H10B/V+T implements a quad-input window comparator architecture with independent internal references and factory-trimmed UV/OV thresholds per channel. Each input supports programmable nominal voltage (1.0V–5.0V), tolerance (±4% to ±11%), and hysteresis (0.25% or 0.50%), enabling precise rail-specific fault detection without external components.

All four reset outputs share a single 560ms minimum timeout period and assert low when any monitored voltage falls outside its programmed window. The device guarantees correct reset output logic state down to VDD = 1.07V and draws only 12.5μA typical supply current, making it suitable for always-on automotive domains.

FAQ

What is the factory-programmed nominal input voltage configuration for MAX16132H10B/V+T?

The "H10" suffix in MAX16132H10B/V+T indicates a quad-input configuration with nominal voltages of 3.3V (IN1), 1.0V (IN2), 1.0V (IN3), and 3.3V (IN4), per Table 4 (Quad-Input Nominal Voltage Options) in the datasheet. This pairing supports common automotive rail combinations such as I/O + core + auxiliary + interface supplies.

Does MAX16132H10B/V+T support independent reset outputs for each of its four inputs?

No. MAX16132H10B/V+T features dual active-low open-drain reset outputs: RESET1 asserts when IN1 or IN2 falls outside its window, and RESET2 asserts when IN3 or IN4 falls outside its window. It does not provide four independent reset signals - that functionality is reserved for the MAX16134 triple variant with three outputs.

What is the meaning of the "/V" and "+T" in MAX16132H10B/V+T?

In MAX16132H10B/V+T, "/V" denotes AEC-Q100 qualification for automotive use (-40°C to +125°C), and "+T" indicates tape-and-reel packaging. The "B" suffix specifies ±4% window tolerance with 0.25% hysteresis per input, and "H10" defines the quad-input nominal voltage set (3.3V/1.0V/1.0V/3.3V).

How does the 560ms reset timeout period in MAX16132H10B/V+T affect system boot timing?

The 560ms minimum reset timeout (suffix "T") ensures the reset signal remains asserted long enough for automotive MCUs to complete oscillator stabilization, PLL lock, flash initialization, and first-stage bootloader execution. This eliminates need for external RC timing networks and guarantees deterministic release timing across temperature and voltage variations.

Can unused inputs on MAX16132H10B/V+T be left floating?

No. Per the Applications Information section, all unused IN_ inputs on MAX16132H10B/V+T must be connected to their respective nominal voltage setting (e.g., tie IN2 to 1.0V if configured as 1.0V nominal) to prevent false resets caused by noise or leakage. Floating inputs are not permitted and violate recommended operation.
