Analog Devices Inc./Maxim Integrated MAX16910DASA8/V+T

Overview

MAX16910DASA8/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 (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 automotive body control modules and battery-powered telematics.

For engineers reviewing the MAX16910DASA8/V+T datasheet, MAX16910DASA8/V+T pinout, MAX16910DASA8/V+T application, or MAX16910DASA8/V+T equivalent, this page provides verified package mapping (8-pin SO-EP), confirmed RESET timing behavior (60µs default delay), thermal shutdown (+180°C), short-circuit protection (330mA limit), and exact fixed-output configuration logic for direct integration into ASIL-B–compatible power domains.

Technical Context

The MAX16910DASA8/V+T implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated thermal foldback and current-limiting circuitry. Its ENABLE input withstands +45V and features internal 0.65µA pulldown, enabling direct connection to battery rails without external biasing.

RESET functionality uses dual fixed thresholds (87.5% or 92.5% of VOUT) with open-drain output and externally adjustable timeout via TIMEOUT pin capacitance. The SET/SETOV interface supports three modes: +3.3V fixed (SET=GND, SETOV=GND), +5V fixed (SET=GND, SETOV=OUT), or adjustable (SET=IN, SETOV=divider), all validated across −40°C to +125°C.

Key Specifications

Pinout & Package

MAX16910DASA8/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 solder connection to PCB ground plane for thermal performance (θJC = 7°C/W).

FAQ

What output voltage options does the MAX16910DASA8/V+T support?

The MAX16910DASA8/V+T supports three configurations: fixed +3.3V (SET=GND, SETOV=GND), fixed +5V (SET=GND, SETOV=OUT), or adjustable 1.5V–11V (SET=IN, SETOV=external resistor divider). All modes are validated across −40°C to +125°C and require no external components beyond the specified bypass capacitors.

How does the RESET function behave during thermal shutdown on the MAX16910DASA8/V+T?

During thermal shutdown, the MAX16910DASA8/V+T asserts RESET low immediately and maintains it until the junction cools by 25°C and regulation resumes. This ensures downstream microcontrollers detect thermal fault conditions and execute safe shutdown sequences - consistent with ISO 26262 diagnostic coverage requirements.

Can the MAX16910DASA8/V+T operate during cold-crank conditions?

Yes - the MAX16910DASA8/V+T operates down to +3.5V input and maintains regulation with 280mV dropout at 200mA, enabling stable 3.3V output even when battery voltage dips to 3.58V during cold-crank. Its −40°C to +125°C rating ensures functionality across full automotive ambient ranges.

What is the purpose of the TIMEOUT pin on the MAX16910DASA8/V+T?

The TIMEOUT pin on the MAX16910DASA8/V+T adjusts the RESET deassertion delay after VOUT recovers: unconnected yields 60µs, while connecting a capacitor to GND extends it (e.g., 8nF → 10ms). This allows precise alignment with microcontroller reset timing requirements without external RC networks.

Is the MAX16910DASA8/V+T pin-compatible with other variants in the MAX16910 family?

Yes - all MAX16910 variants, including MAX16910DASA8/V+T, share identical 8-pin SO-EP pinout and footprint. Differences are limited to RESET threshold (87.5% vs. 92.5%), temperature grade (Grade 1 vs. Grade 0), and qualification status (automotive /V+ vs. commercial), enabling drop-in replacement within same package type.
