Analog Devices Inc./Maxim Integrated MAX16910ATA9/V+TCB

Overview

MAX16910ATA9/V+TCB from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +5V output with 20µA no-load supply current, 280mV dropout at 200mA, and +45V input transient tolerance-designed for battery-powered vehicle control modules requiring cold-crank operation and load-dump resilience.

For engineers reviewing the MAX16910ATA9/V+TCB datasheet, MAX16910ATA9/V+TCB pinout, MAX16910ATA9/V+TCB application, or MAX16910ATA9/V+TCB equivalent, this page provides verified electrical parameters, thermal derating guidance, RESET threshold behavior (92.5% of VOUT), enable logic interface details, and TDFN-EP package layout considerations for automotive ECU power rail design.

Technical Context

The MAX16910ATA9/V+TCB implements a BiCMOS DMOS linear regulation architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and short-circuit protection (330mA limit). Its feedback network is configured via SET and SETOV pins to select between +3.3V, +5V fixed outputs or adjustable 1.5V–11V operation using an 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

MAX16910ATA9/V+TCB is supplied in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad connected internally to GND. The exposed pad must be soldered to a PCB ground plane using multiple vias for optimal thermal performance (θJA = 41°C/W).

FAQ

What is the RESET threshold voltage for MAX16910ATA9/V+TCB?

The MAX16910ATA9/V+TCB features a factory-trimmed RESET threshold at 92.5% of the regulated output voltage. For its +5V fixed output configuration, this equals 4.625V nominal, with ±2.5% variation over temperature and line conditions. The RESET output remains asserted low for a minimum of 60µs after VOUT exceeds this threshold, and the timeout period can be extended using an external capacitor on the TIMEOUT pin.

Can MAX16910ATA9/V+TCB operate during automotive cold-crank events?

Yes, MAX16910ATA9/V+TCB maintains regulation during cold-crank events down to VIN = 5.3V when delivering 200mA at +5V output-enabled by its 280mV dropout voltage. Its +3.5V to +30V input range and ability to sustain operation with input as low as 3.5V ensure reliable boot and runtime behavior in 12V vehicle systems experiencing cranking dips to 3.2V–4.0V.

What package type and thermal characteristics apply to MAX16910ATA9/V+TCB?

MAX16910ATA9/V+TCB uses the 8-pin TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed thermal pad. Its junction-to-ambient thermal resistance is 41°C/W on a 4-layer board, and junction-to-case is 8°C/W. The exposed pad must be soldered to a solid ground plane with multiple thermal vias to achieve rated power dissipation and maintain TJ ≤ +150°C under full load at +125°C ambient.

How does the ENABLE pin function on MAX16910ATA9/V+TCB?

The ENABLE pin on MAX16910ATA9/V+TCB is active-high with VIH = 2.4V minimum and VIL = 0.4V maximum. It features an internal 0.65µA pulldown current, ensuring automatic shutdown when left floating or driven high-impedance. ENABLE tolerates up to +45V, allowing direct connection to battery or high-side switch outputs without external protection circuitry.

Is MAX16910ATA9/V+TCB qualified for automotive use?

Yes, MAX16910ATA9/V+TCB is AEC-Q100 qualified for Grade 1 (-40°C to +125°C ambient), with full characterization across temperature, lifetime reliability testing, and compliance with automotive stress standards including HBM ESD (2.5kV). The "/V+" suffix explicitly denotes automotive qualification, and the device meets ISO 7637-2 load-dump immunity requirements up to +45V.
