Analog Devices Inc./Maxim Integrated MAX16910CATA8/V+T

Overview

MAX16910CATA8/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at +3.3V or +5V fixed output (87.5% RESET threshold), operating from +3.5V to +30V input with only 20µA no-load supply current and +45V transient tolerance - ideal for always-on automotive body control modules requiring cold-crank operation and load-dump resilience.

For engineers reviewing the MAX16910CATA8/V+T datasheet, MAX16910CATA8/V+T pinout, MAX16910CATA8/V+T application, or MAX16910CATA8/V+T equivalent, this page delivers verified technical context, package-specific pin functions, real-world design meaning of key specs, and two validated alternative parts with documented functional and application-level differences.

Technical Context

The MAX16910CATA8/V+T implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and short-circuit protection (330mA typ). Its SET/SETOV dual-input configuration enables mode selection between fixed +3.3V/+5V outputs or adjustable 1.5V–11V via external resistive divider, with internal 1.25V reference and ±1.5% output voltage accuracy over temperature.

It features an open-drain, active-low RESET output with factory-trimmed 87.5% falling-threshold (MAX16910CATA8/V+T variant), fixed 60µs timeout (extendable via TIMEOUT capacitor), and ENABLE input tolerant to +45V - supporting direct connection to battery rail for fail-safe enable control in automotive power domains.

Key Specifications

Pinout & Package

MAX16910CATA8/V+T is housed in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad internally connected to GND. The exposed pad must be soldered to PCB ground plane using multiple vias for optimal thermal performance (θJC = 8°C/W).

FAQ

What is the RESET threshold voltage for MAX16910CATA8/V+T?

The MAX16910CATA8/V+T has a factory-trimmed RESET threshold of 87.5% of the output voltage (e.g., 2.8875V for 3.3V output, 4.375V for 5V output) on the falling edge of VOUT. This value is specified in the Ordering Information table and confirmed in Electrical Characteristics (Note: MAX16910CATA8/V+T corresponds to "8" suffix, 87.5% option). The RESET remains asserted low for 60µs after VOUT exceeds threshold.

Does MAX16910CATA8/V+T support adjustable output voltage?

Yes, MAX16910CATA8/V+T supports adjustable output from +1.5V to +11V by configuring SET = high (>2.4V) and connecting SETOV to an external resistive divider between OUT and GND. The output is calculated as VOUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ. Fixed +3.3V/+5V modes are selected by grounding SET and tying SETOV to GND or OUT respectively.

What package type does MAX16910CATA8/V+T use?

MAX16910CATA8/V+T uses an 8-pin TDFN-EP (3mm × 3mm) package with exposed thermal pad. The "T" in the part number denotes TDFN, and "A8" confirms the 8-pin variant. The exposed pad must be soldered to PCB ground for thermal performance (θJA = 41°C/W) and electrical stability.

Is MAX16910CATA8/V+T AEC-Q100 qualified?

Yes, MAX16910CATA8/V+T is AEC-Q100 qualified - indicated by the "/V" suffix in the part number and explicitly stated in the Ordering Information and Features sections. It operates over -40°C to +125°C ambient temperature and meets automotive reliability stress testing requirements.

How does the ENABLE pin function on MAX16910CATA8/V+T?

The ENABLE pin on MAX16910CATA8/V+T is active-high with internal 0.65µA pulldown. Driving ENABLE ≥2.4V turns the regulator on; pulling it ≤0.4V places MAX16910CATA8/V+T in shutdown (1.6µA IQ). ENABLE tolerates up to +45V, allowing direct connection to battery rail - a key feature for automotive always-on architectures.
