Analog Devices Inc./Maxim Integrated MAX16910CATA9/V+T

Overview

MAX16910CATA9/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at +5V or +3.3V fixed output (this variant: 92.5% RESET threshold), operating from +3.5V to +30V input with +45V transient tolerance and 20µA no-load supply current. It integrates active-low open-drain RESET, ENABLE control, thermal shutdown, and short-circuit protection for battery-powered automotive ECUs.

For engineers reviewing the MAX16910CATA9/V+T datasheet, MAX16910CATA9/V+T pinout, MAX16910CATA9/V+T application, or MAX16910CATA9/V+T equivalent, key selection criteria include its 92.5% reset threshold, 280mV dropout at 200mA, -40°C to +125°C operation, TDFN-EP 3mm × 3mm package, and compatibility with 4.7µF ceramic output capacitors.

Technical Context

The MAX16910CATA9/V+T implements a high-voltage BiCMOS DMOS linear regulator architecture with integrated feedback multiplexer (SETOV/SET pins) enabling fixed (+3.3V/+5V) or adjustable (1.5V–11V) output configurations. Its internal 1.25V reference and precision resistive divider sensing support ±1% output voltage accuracy over temperature and line.

RESET functionality uses dual fixed thresholds (92.5% V_OUT falling edge, 5% hysteresis rising edge) with programmable timeout via external capacitor on TIMEOUT pin; ENABLE withstands +45V and features internal 0.65µA pulldown for robust three-state interface handling.

Key Specifications

Pinout & Package

MAX16910CATA9/V+T is housed 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 PCB ground plane for optimal thermal performance (θ_JC = 8°C/W).

FAQ

What is the RESET threshold voltage for MAX16910CATA9/V+T?

The MAX16910CATA9/V+T features a fixed RESET threshold of 92.5% of the output voltage (e.g., 4.625V for a 5V output) when V_OUT is falling, with 5% hysteresis on the rising edge. This threshold is factory-set and cannot be adjusted; it is distinct from the 87.5% option in the MAX16910CATA8/V+T variant. The MAX16910CATA9/V+T maintains this behavior across its full -40°C to +125°C operating range.

Can MAX16910CATA9/V+T be configured for adjustable output voltage?

Yes, MAX16910CATA9/V+T supports adjustable output from +1.5V to +11V by connecting the SET pin to IN (or >2.4V) and using an external resistive divider between OUT and SETOV. The output is calculated as V_OUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ. This configuration retains all other features-including the 92.5% RESET threshold and 20µA quiescent current-making MAX16910CATA9/V+T suitable for custom voltage rails in automotive subsystems.

What package type and thermal performance does MAX16910CATA9/V+T use?

MAX16910CATA9/V+T uses an 8-pin TDFN-EP package (3mm × 3mm) with exposed thermal pad connected to GND. Its junction-to-ambient thermal resistance is 41°C/W (on multilayer board), and junction-to-case is 8°C/W. To achieve rated 200mA output at high ambient temperatures, the exposed pad must be soldered to a solid ground plane with multiple thermal vias-enabling reliable operation up to +125°C ambient in space-constrained automotive modules.

How does the TIMEOUT pin function on MAX16910CATA9/V+T?

The TIMEOUT pin on MAX16910CATA9/V+T sets the duration that RESET remains low after V_OUT recovers above threshold. With TIMEOUT unconnected, the default delay is 60µs. Connecting a capacitor (e.g., 8nF) from TIMEOUT to GND extends the delay (e.g., to 10ms) using C_TIMEOUT(nF) = 0.8 × I_TO(µA) × T_TIMEOUT(ms). This allows precise alignment with microcontroller reset timing requirements without external components-enhancing system reliability in MAX16910CATA9/V+T designs.

Is MAX16910CATA9/V+T AEC-Q100 qualified and what grade does it meet?

Yes, MAX16910CATA9/V+T is AEC-Q100 qualified and rated for Grade 1 (-40°C to +125°C ambient), with full characterization across that range including thermal shutdown at +180°C junction and operation up to +150°C junction temperature. The "/V+" suffix explicitly denotes automotive qualification, and the device meets ISO 16750-2 for electrical transients-making MAX16910CATA9/V+T suitable for under-hood and safety-critical automotive applications without additional qualification testing.
