Product details
Overview
The MAX16910DASA8+ from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA output with only 20µA no-load supply current and 1.6µA shutdown current. It operates from +3.5V to +30V input, withstands +45V transients, and supports fixed +3.3V or +5V outputs (this variant uses 87.5% RESET threshold). It is used in automotive body control modules and infotainment power rails requiring cold-crank operation and load-dump resilience.
For engineers reviewing the MAX16910DASA8+ datasheet, MAX16910DASA8+ pinout, MAX16910DASA8+ application, or MAX16910DASA8+ equivalent, key selection criteria include its 280mV dropout at 200mA, open-drain active-low RESET with adjustable timeout, thermal/short-circuit protection, and SO-EP package compatibility with automotive AEC-Q100 stress requirements.
Technical Context
The MAX16910DASA8+ implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated feedback MUX for mode selection (fixed 3.3V/5V or adjustable via external divider). Its ENABLE input is active-high with internal 0.65µA pulldown and +45V tolerance, enabling direct connection to battery rails.
RESET functionality uses dual fixed thresholds (87.5% or 92.5% of VOUT) with 60µs default timeout extendable via TIMEOUT pin capacitor; the open-drain output asserts low during undervoltage, ENABLE deactivation, or thermal shutdown. Thermal protection activates at +180°C with +25°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V transient tolerant for automotive load-dump survival |
| Quiescent Current | 20µA at no load - enables >10-year battery standby in always-on vehicle modules |
| Output Current | Up to 200mA continuous - sufficient for MCU cores, CAN transceivers, and sensor interfaces |
| Dropout Voltage | 280mV at 200mA - ensures regulation during cold-crank (as low as ~4.5V battery) |
| RESET Threshold | 87.5% of VOUT (fixed) - provides precise brown-out detection for microcontroller reset coordination |
| Operating Temperature | -40°C to +125°C - qualified for under-hood and cabin-mounted automotive applications |
| Package | 8-pin SO-EP (5mm × 4mm) with exposed pad - enables efficient PCB heat sinking in constrained layouts |
Pinout & Package
MAX16910DASA8+ is housed in an 8-pin SO-EP (small-outline, exposed pad) package measuring 5mm × 4mm. The exposed pad (EP) is internally connected to GND and must be soldered to the PCB ground plane for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Battery rail connection; requires ≥1µF low-ESR ceramic bypass to GND for stability |
| 2 ENABLE | Active-high enable | Drives regulator ON/OFF; +45V tolerant; internal 0.65µA pulldown holds shutdown when floating |
| 3 SET | Feedback mode selector | GND = fixed-output mode; >2.4V = adjustable mode using external resistive divider |
| 4 RESET | Open-drain active-low reset | Asserts low on VOUT undervoltage, ENABLE deactivation, or thermal shutdown; requires external pull-up |
| 5 TIMEOUT | Reset timeout adjust | Capacitor-to-GND sets delay beyond 60µs default; 1nF ≈ 1.25ms extension |
| 6 SETOV | Output voltage selector | GND = 3.3V fixed; OUT = 5V fixed; external divider = 1.5V–11V adjustable |
| 7 GND | Power ground | Reference for all signals; connects to EP for thermal conduction |
| 8 OUT | Regulated output | Delivers stable 3.3V/5V or adjustable voltage; requires ≥4.7µF low-ESR ceramic output capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA no-load operation meets ISO 16750-2 Class D and UNECE R100 standby current limits |
| Load-dump robustness | +45V input transient tolerance eliminates need for external TVS in 12V automotive systems |
| Integrated RESET generator | Eliminates discrete reset IC; 87.5% threshold and programmable timeout reduce BOM count |
| Thermal & short-circuit protection | Auto-recovering +180°C shutdown with +25°C hysteresis prevents latch-up during fault conditions |
| Fixed +3.3V/+5V or adjustable output | Single device supports multiple rail requirements without redesign - SET/SETOV pin configuration defines mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CASA8/V+ | Same SO-EP package and 87.5% RESET threshold, but automotive-qualified (AEC-Q100 Grade 2); identical electrical specs | Required for production automotive ECUs needing full qualification documentation and PPAP support | Select MAX16910CASA8/V+ when AEC-Q100 compliance is mandatory; MAX16910DASA8+ is suitable for industrial or non-safety-critical automotive subsystems |
| TLE42744G | Infineon automotive LDO; 150mA output, 45µA IQ, fixed 5V only, no RESET output | Lacks integrated RESET and adjustable output; requires external reset supervisor IC for MCU coordination | Choose TLE42744G only if RESET functionality is handled elsewhere and lower output current suffices; MAX16910DASA8+ consolidates power and reset functions |
Compared with MAX16910CASA8/V+, MAX16910DASA8+ offers identical performance and package but omits formal AEC-Q100 certification-making it ideal for cost-sensitive industrial or Tier-2 automotive designs. Versus TLE42744G, MAX16910DASA8+ adds RESET integration and higher output current, reducing system-level component count.

FAQ
What output voltage options does the MAX16910DASA8+ support?
The MAX16910DASA8+ supports fixed +3.3V or +5V outputs via SETOV pin configuration (GND or OUT), or an adjustable 1.5V–11V range using an external resistive divider. This variant defaults to 87.5% RESET threshold and is configured for fixed output in typical applications. Its flexibility eliminates the need for multiple SKUs in multi-rail designs.
How does the MAX16910DASA8+ handle automotive load-dump transients?
The MAX16910DASA8+ withstands +45V input transients for ≤400ms, meeting ISO 7637-2 Pulse 5a requirements. Its internal protection circuitry maintains regulation during load-dump events without external TVS diodes, simplifying front-end design and improving reliability in 12V automotive systems.
What is the purpose of the TIMEOUT pin on the MAX16910DASA8+?
The TIMEOUT pin on the MAX16910DASA8+ allows adjustment of the RESET timeout period beyond the default 60µs. Connecting a capacitor from TIMEOUT to GND extends the delay - e.g., 1nF yields ~1.25ms - enabling synchronization with slow-starting microcontrollers or complex power-up sequences in automotive ECUs.
Does the MAX16910DASA8+ require special PCB layout considerations?
Yes. The MAX16910DASA8+ SO-EP package requires the exposed pad (EP) to be soldered to a solid ground plane using multiple thermal vias. Input and output capacitors must be low-ESR ceramics (≥1µF IN, ≥4.7µF OUT), placed close to respective pins to ensure stability and transient response per Analog Devices' layout guidelines.
Is the MAX16910DASA8+ AEC-Q100 qualified?
No. The MAX16910DASA8+ is not AEC-Q100 qualified. For automotive production applications requiring formal qualification, select the MAX16910CASA8/V+ variant, which carries full AEC-Q100 Grade 2 certification. MAX16910DASA8+ is intended for industrial, commercial vehicle, or non-safety-critical automotive subsystems where qualification is not mandated.
