Analog Devices Inc./Maxim Integrated MAX16910EATA9/V+T

Overview

MAX16910EATA9/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at +5V fixed output with 20µA no-load supply current, 280mV dropout at 200mA, and +45V input transient tolerance-designed for battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.

For engineers reviewing the MAX16910EATA9/V+T datasheet, MAX16910EATA9/V+T pinout, MAX16910EATA9/V+T application, or MAX16910EATA9/V+T equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade thermal/short-circuit protection, and precise RESET threshold (92.5% of VOUT) and timeout behavior-enabling direct integration into ASIL-B–compatible power domains without external reset supervision.

Technical Context

The MAX16910EATA9/V+T implements a high-voltage BiCMOS DMOS linear regulator architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and 330mA short-circuit current limiting. Its SET/SETOV dual-input configuration selects between 3.3V/5V fixed outputs or 1.5V–11V adjustable regulation via external resistive divider.

It features an open-drain, active-low RESET output with factory-trimmed 92.5% VOUT threshold and 60µs default timeout-extendable via TIMEOUT pin capacitor-and supports high-voltage ENABLE input (up to +45V) with internal 0.65µA pulldown for robust three-state driver compatibility.

Key Specifications

Pinout & Package

MAX16910EATA9/V+T is housed in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad connected internally to GND. The exposed pad must be soldered to PCB ground plane for optimal thermal performance (θJA = 41°C/W).

FAQ

What is the RESET threshold voltage for MAX16910EATA9/V+T?

The MAX16910EATA9/V+T features a fixed RESET threshold at 92.5% of the regulated output voltage. For a 5V output setting, this corresponds to 4.625V nominal; the threshold remains stable across -40°C to +125°C with ±0.5% variation. This value is factory-trimmed and does not require external calibration. The MAX16910EATA9/V+T asserts RESET low when VOUT falls below this point and holds it low for ≥60µs after recovery.

Can MAX16910EATA9/V+T be used in adjustable-output mode?

Yes, the MAX16910EATA9/V+T supports adjustable output from +1.5V to +11V using an external resistive divider between OUT and SETOV, provided SET is driven above 2.4V (e.g., connected to IN). In this mode, the internal 1.25V feedback reference (VSETOV) sets VOUT = 1.25V × (1 + R1/R2). The MAX16910EATA9/V+T maintains 20µA quiescent current and full thermal/short-circuit protection regardless of output voltage selection.

What package type does MAX16910EATA9/V+T use?

The MAX16910EATA9/V+T uses an 8-pin TDFN-EP (3mm × 3mm) package with exposed thermal pad. This package provides θJA = 41°C/W and θJC = 8°C/W, enabling efficient heat dissipation in compact automotive modules. The exposed pad must be soldered to the PCB ground plane using multiple thermal vias-failure to do so risks exceeding +150°C junction temperature under 200mA load at high ambient temperatures.

How does the TIMEOUT pin extend the RESET delay on MAX16910EATA9/V+T?

The TIMEOUT pin on MAX16910EATA9/V+T allows extension of the RESET timeout period beyond the default 60µs by connecting a capacitor to GND. The delay scales as 1.25ms per nF (CTIMEOUT in nF), e.g., a 10nF capacitor yields ~12.5ms timeout. The MAX16910EATA9/V+T specifies low-leakage (<10nA) capacitors; ceramic types are recommended. Leaving TIMEOUT open retains the 60µs factory-default delay.

Is MAX16910EATA9/V+T qualified for automotive applications?

Yes, MAX16910EATA9/V+T is AEC-Q100 Grade 1 qualified (-40°C to +125°C) and designed for automotive use, featuring +45V input transient tolerance, cold-crank operation down to +3.5V, and integrated thermal shutdown (+180°C) with hysteresis. It meets ISO 16750-2 for electrical loads and ISO 7637-2 for transient immunity-making it suitable for body control, ADAS, and telematics ECUs without additional protection circuitry.
