Analog Devices Inc./Maxim Integrated MAX16910DASA8/V+

Overview

MAX16910DASA8/V+ 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 supports 87.5% RESET threshold), with 20µA no-load IQ, 280mV dropout at 200mA, and +45V transient tolerance-designed for battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.

For engineers reviewing the MAX16910DASA8/V+ datasheet, MAX16910DASA8/V+ pinout, MAX16910DASA8/V+ application, or MAX16910DASA8/V+ equivalent, key selection criteria include its -40°C to +125°C operating range, open-drain active-low RESET with adjustable timeout, thermal/short-circuit protection, and SO-EP 8-pin package compatibility with high-voltage enable and adjustable output configuration.

Technical Context

The MAX16910DASA8/V+ implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and 330mA short-circuit current limiting. Its feedback network is selectable via SET and SETOV pins to configure fixed 3.3V/5V outputs or adjustable 1.5V–11V using an external resistive divider referenced to 1.25V SETOV voltage.

RESET functionality uses internal comparators monitoring OUT voltage against fixed thresholds (87.5% or 92.5% of VOUT); the open-drain output asserts low during undervoltage, ENABLE deactivation, or thermal shutdown, with a default 60µs timeout extendable via TIMEOUT pin capacitor. ENABLE withstands +45V and features internal 0.65µA pulldown for reliable shutdown control.

Key Specifications

Pinout & Package

FAQ

What is the RESET threshold voltage for MAX16910DASA8/V+?

The MAX16910DASA8/V+ features an 87.5% RESET threshold, meaning the open-drain RESET output asserts low when the regulated output voltage falls below 87.5% of its nominal value (e.g., 2.8875V for a 3.3V output or 4.375V for a 5V output). This threshold is factory-set and not user-adjustable; it remains stable over temperature and load conditions as specified in the Electrical Characteristics table.

Can MAX16910DASA8/V+ be configured for adjustable output voltage?

Yes, MAX16910DASA8/V+ supports adjustable output voltage from +1.5V to +11V by connecting the SET pin to IN (or >2.4V) and configuring SETOV as the feedback node with an external resistive divider between OUT and GND. The output voltage follows VOUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ. Fixed 3.3V/5V modes are selected by grounding SET and tying SETOV to GND or OUT respectively.

What package type does MAX16910DASA8/V+ use, and how should the exposed pad be handled?

MAX16910DASA8/V+ uses an 8-pin SO-EP (small-outline with exposed pad) package measuring 5mm × 4mm. The exposed pad is internally connected to GND and must be soldered to the PCB ground plane using multiple thermal vias to achieve θJA = 53°C/W. Failure to connect the pad degrades thermal performance and risks exceeding junction temperature limits under load.

Does MAX16910DASA8/V+ include short-circuit and thermal protection?

Yes, MAX16910DASA8/V+ integrates both short-circuit protection (330mA current limit) and thermal shutdown (+180°C trip with +25°C hysteresis). During sustained overload, the device cycles ON/OFF to prevent damage while maintaining safe junction temperatures. These protections are fully operational across the -40°C to +125°C automotive temperature range and require no external components.

How is the RESET timeout period adjusted on MAX16910DASA8/V+?

The RESET timeout period on MAX16910DASA8/V+ is adjusted by connecting a capacitor from the TIMEOUT pin to GND. With no capacitor, the internal 60µs delay applies. Using the formula CTIMEOUT (nF) = 0.8 × ITO (µA) × TTIMEOUT (ms), where ITO = 1.0µA (typ), a 10nF capacitor yields ~12.5ms delay. Ceramic capacitors ≥100pF are recommended; low-leakage types ensure accuracy.
