Analog Devices Inc./Maxim Integrated MAX16910EASA8/V+T

Overview

The MAX16910EASA8/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +3.3V or +5V output (this variant: 87.5% RESET threshold), operating from +3.5V to +30V input with +45V transient tolerance, and consuming only 20µA quiescent current - ideal for always-on battery-powered modules in vehicle body control units.

For engineers reviewing the MAX16910EASA8/V+T datasheet, MAX16910EASA8/V+T pinout, MAX16910EASA8/V+T application, or MAX16910EASA8/V+T equivalent, key selection criteria include its -40°C to +125°C automotive temperature range, 280mV dropout at 200mA, open-drain active-low RESET with adjustable timeout, thermal/short-circuit protection, and SO-EP 8-pin package compatibility with load-dump resilience.

Technical Context

The MAX16910EASA8/V+T implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated feedback multiplexing: SET and SETOV pins configure fixed (+3.3V/+5V) or adjustable (1.5V–11V) output modes via internal 1.25V reference and external resistive divider. Its ENABLE input withstands +45V and features internal 0.65µA pulldown for reliable shutdown.

RESET functionality uses dual factory-set thresholds (87.5% or 92.5% of VOUT, this variant = 87.5%), with a default 60µs timeout extendable via TIMEOUT pin capacitor; thermal shutdown activates at +180°C with +25°C hysteresis, and short-circuit current limit is typ. 330mA.

Key Specifications

Pinout & Package

MAX16910EASA8/V+T is housed in an 8-pin SO-EP (small-outline, exposed pad) package measuring 5mm × 4mm, with the exposed pad internally connected to GND and requiring soldering to PCB ground plane for optimal thermal performance (θJA = 53°C/W, θJC = 7°C/W).

FAQ

What output voltage options does the MAX16910EASA8/V+T support?

The MAX16910EASA8/V+T supports fixed +3.3V or +5V outputs (configured via SETOV pin connection), or adjustable output from +1.5V to +11V using an external resistive divider. This variant's RESET threshold is fixed at 87.5% of the selected output voltage, and its SO-EP package enables compact, thermally robust placement in automotive PCBs.

How does the RESET function operate on the MAX16910EASA8/V+T?

The MAX16910EASA8/V+T features an open-drain, active-low RESET output that asserts low when the regulated output falls below 87.5% of its nominal value, or when ENABLE is low or thermal shutdown occurs. The RESET signal remains low for a default 60µs after recovery, extendable via a capacitor on the TIMEOUT pin - eliminating need for external reset supervisors.

What is the maximum continuous output current for MAX16910EASA8/V+T at 125°C ambient?

At TA = +125°C, the MAX16910EASA8/V+T (SO-EP package) has a maximum allowable power dissipation of ~620mW. With VIN = 14V and VOUT = 3.3V, this limits continuous output current to approximately 58mA. At lower ambient temperatures or smaller VIN–VOUT differentials, full 200mA is achievable - always verify against thermal derating curves.

Is the MAX16910EASA8/V+T pin-compatible with other MAX16910 variants in SO-EP packaging?

Yes - all MAX16910 variants in the 8-pin SO-EP package (e.g., MAX16910CASA8/V+, MAX16910DASA8/V+, MAX16910EASA8/V+T) share identical pinout, footprint, and thermal pad layout. Differences lie only in RESET threshold (87.5% vs. 92.5%), qualification grade (commercial vs. automotive), and ESD rating - allowing drop-in replacement where specification alignment permits.

Does the MAX16910EASA8/V+T require an external capacitor on the TIMEOUT pin for basic operation?

No - the MAX16910EASA8/V+T operates with a default 60µs RESET timeout period when the TIMEOUT pin is left unconnected. An external capacitor is optional and used only when longer reset assertion times (e.g., for slow-starting MCUs) are required; typical values range from 100pF to 10nF depending on desired delay.
