Analog Devices Inc./Maxim Integrated MAX16910DATA9/V+T

Overview

The MAX16910DATA9/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA output with only 20µA no-load supply current and 1.6µA shutdown current. It operates from +3.5V to +30V input (transient-tolerant to +45V), supports fixed +5V or +3.3V outputs (this variant uses 92.5% RESET threshold), and features open-drain active-low RESET with adjustable timeout-ideal for battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.

For engineers reviewing the MAX16910DATA9/V+T datasheet, MAX16910DATA9/V+T pinout, MAX16910DATA9/V+T application, or MAX16910DATA9/V+T equivalent, key selection criteria include its -40°C to +125°C operating range, 280mV dropout at 200mA, 4.7µF minimum stable output capacitance, RESET threshold accuracy (±2.5% of VOUT), and TDFN-EP 3mm × 3mm 8-pin thermally enhanced package.

Technical Context

The MAX16910DATA9/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 typical limit). Its SET/SETOV configuration logic enables three operating modes: +3.3V fixed (SETOV = GND), +5V fixed (SETOV = OUT), or adjustable 1.5V–11V (SET = IN, external resistive divider).

RESET functionality is tightly coupled to output voltage monitoring: it asserts low when VOUT falls below 92.5% of nominal output (e.g., 4.625V for 5V mode), remains low for ≥60µs after recovery, and is extended via TIMEOUT pin capacitor. ENABLE is active-high with internal 0.65µA pulldown and +45V absolute maximum rating-enabling direct connection to battery rail.

Key Specifications

Pinout & Package

MAX16910DATA9/V+T is housed in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad internally connected to GND. The exposed pad must be soldered to a PCB ground plane using multiple vias for optimal thermal performance (θJC = 8°C/W).

FAQ

What is the RESET threshold voltage for MAX16910DATA9/V+T?

The MAX16910DATA9/V+T features a fixed RESET threshold of 92.5% of the nominal output voltage, with ±2.5% tolerance. For a +5V output configuration, this corresponds to 4.625V ±125mV. The threshold is monitored continuously and triggers an active-low open-drain RESET signal when VOUT falls below this level, remaining asserted for ≥60µs after recovery.

Can MAX16910DATA9/V+T be used in adjustable-output mode?

Yes, MAX16910DATA9/V+T supports adjustable output from +1.5V to +11V by connecting SET to IN (or >2.4V) and using an external resistive divider between OUT and SETOV. The output voltage follows VOUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ. This mode retains all protections and specifications, including 20µA quiescent current and +45V input tolerance.

What package type does MAX16910DATA9/V+T use?

MAX16910DATA9/V+T is supplied in an 8-pin TDFN-EP (3mm × 3mm) package with exposed thermal pad. The pad is internally connected to GND and must be soldered to the PCB ground plane using multiple thermal vias to achieve the specified θJA of 41°C/W and ensure safe operation at full 200mA load across -40°C to +125°C.

How does the TIMEOUT pin affect MAX16910DATA9/V+T reset behavior?

The TIMEOUT pin on MAX16910DATA9/V+T sets the duration that RESET remains low after VOUT recovers from undervoltage. With TIMEOUT open, the default delay is 60µs. Connecting a capacitor (e.g., 1nF) from TIMEOUT to GND extends the delay to ~1.25ms using the formula tRP = 1.25 × CTIMEOUT (ms/nF). Ceramic capacitors ≥100pF are recommended for stability.

Is MAX16910DATA9/V+T qualified for automotive applications?

Yes, MAX16910DATA9/V+T is AEC-Q100 qualified and rated for -40°C to +125°C operation. It meets automotive environmental requirements including load-dump immunity (+45V transient tolerance), cold-crank capability (operation down to +3.5V), and robust ESD performance (2.5kV HBM). The "/V+" suffix explicitly denotes automotive qualification per Analog Devices' ordering nomenclature.
