Product details
Overview
MAX16910DASA9+ from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at +5V or +3.3V fixed output (92.5% RESET threshold), operating from +3.5V to +30V input with +45V transient tolerance-designed for battery-powered and load-dump-prone automotive ECUs.
For engineers reviewing the MAX16910DASA9+ datasheet, MAX16910DASA9+ pinout, MAX16910DASA9+ application, or MAX16910DASA9+ equivalent, this page provides verified package mapping (8-pin SO-EP), confirmed RESET delay adjustability via TIMEOUT pin, thermal shutdown behavior at +180°C, and validated alternative options for automotive power-rail supervision.
Technical Context
The MAX16910DASA9+ implements a high-voltage BiCMOS DMOS pass transistor architecture with internal feedback selection logic controlled by SET and SETOV pins. It integrates a precision 1.25V reference, open-drain RESET comparator with hysteresis, and a programmable timeout ramp generator driven by a 1.0μA internal current source.
Its enable circuitry features a +45V-tolerant active-high input with internal 0.65μA pulldown, supporting direct connection to battery rails. Thermal protection triggers at +180°C with +25°C hysteresis, and short-circuit current limiting is fixed at 330mA (typ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V tolerant for ≤400ms-enables operation during automotive load-dump transients. |
| Quiescent Current | 20μA at no load-meets <100μA module standby requirements in always-on automotive modules. |
| Shutdown Current | 1.6μA-minimizes battery drain in parked-vehicle monitoring systems. |
| Output Current | 200mA max-supports microcontroller, CAN transceiver, and sensor power domains in compact ECUs. |
| Dropout Voltage | 280mV at 200mA (5V output)-allows regulation down to VIN = 5.28V, critical for cold-crank operation. |
| RESET Threshold | 92.5% of VOUT (fixed)-provides precise brown-out detection for 5V systems without external components. |
| Operating Temperature | -40°C to +125°C ambient-qualified for under-hood automotive placement per AEC-Q100. |
Pinout & Package
MAX16910DASA9+ is housed in an 8-pin SO-EP (5mm × 4mm) package with exposed thermal pad connected internally to GND. The package supports high-power dissipation (1.861W at +70°C) and requires PCB ground-plane connection via the EP for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Battery rail input; must be bypassed with ≥1μF low-ESR ceramic capacitor to suppress transients. |
| 2 ENABLE | Active-high enable | +45V-tolerant logic input; internal 0.65μA pulldown ensures safe shutdown when unconnected. |
| 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 undervoltage, thermal shutdown, or ENABLE deactivation; requires external pull-up. |
| 5 TIMEOUT | Reset timeout adjustment | Connect capacitor to GND to extend default 60μs delay; 1.25ms/nF scaling factor applies. |
| 6 SETOV | Output voltage selector | GND = 3.3V fixed; OUT = 5V fixed; external divider = 1.5V–11V adjustable output. |
| 7 GND | Power and signal ground | Reference for all analog circuitry; must be tied to PCB ground plane with low-inductance path. |
| 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 enables >1-year battery life in always-on telematics modules with 200mAh coin cells. |
| Integrated RESET with adjustable delay | Eliminates need for discrete reset IC and RC timing network-reduces BOM count and layout area. |
| Load-dump transient tolerance | +45V input rating allows direct connection to 12V automotive battery without external TVS clamping. |
| Thermal and short-circuit protection | Auto-recovering +180°C shutdown with +25°C hysteresis prevents latch-up during sustained overload. |
| Fixed +3.3V/+5V or adjustable output | User-selectable via SET/SETOV pins-supports legacy 5V MCUs and modern 3.3V SoCs on same PCB design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910DASA8/V+ | Same SO-EP package and 87.5% RESET threshold; identical electrical specs except RESET trip point. | Suitable where earlier brown-out detection (at 87.5% of VOUT) is required for slower-starting peripherals. | Select MAX16910DASA8/V+ only if system timing margins require earlier reset assertion than 92.5% threshold allows. |
| TLE42754G | 5V fixed output, 150mA, 40μA IQ, +40V tolerant; no adjustable output or TIMEOUT pin; different pinout (TO-252-3). | Limited to fixed 5V use cases; lacks RESET delay adjustability and dual-threshold flexibility. | Choose TLE42754G only for cost-sensitive, single-rail 5V applications where RESET timing is not adjustable and 200mA output is unnecessary. |
Compared with MAX16910DASA8/V+, the MAX16910DASA9+ offers later reset assertion (92.5% vs. 87.5%), improving noise immunity during marginal supply conditions; versus TLE42754G, it delivers higher output current, lower quiescent current, and configurable reset timing-making it superior for complex automotive ECUs requiring flexible supervision.

FAQ
What is the RESET threshold voltage for MAX16910DASA9+?
The MAX16910DASA9+ features a fixed RESET threshold at 92.5% of the output voltage-e.g., 4.625V for a 5V output or 3.06V for a 3.3V output. This threshold is factory-trimmed and guaranteed over -40°C to +125°C. The MAX16910DASA9+ does not support user-adjustable threshold voltages; alternative variants like MAX16910DASA8/V+ offer 87.5% instead.
Can MAX16910DASA9+ be used in adjustable-output configurations?
Yes, the MAX16910DASA9+ supports adjustable output voltages 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 follows VOUT = 1.25V × (1 + R1/R2). Fixed 3.3V/5V modes are selected via SET and SETOV grounding or tying to OUT-no hardware change is needed to switch modes.
What package type does MAX16910DASA9+ use, and how should the exposed pad be handled?
MAX16910DASA9+ uses an 8-pin SO-EP (5mm × 4mm) package with an exposed thermal pad (EP) internally connected to GND. The EP must be soldered to a large PCB ground plane using multiple thermal vias to achieve specified θJA = 53°C/W and prevent thermal derating. Leaving the EP unconnected degrades thermal performance and risks junction overheating above +125°C ambient.
How is the RESET timeout period adjusted on MAX16910DASA9+?
The RESET timeout period on MAX16910DASA9+ is adjusted by connecting a capacitor from the TIMEOUT pin to GND. With no capacitor, the default delay is 60μs. Using the formula CTIMEOUT (nF) = 0.8 × ITO (μA) × TTIMEOUT (ms), a 10nF capacitor yields ~10ms delay (ITO = 1.0μA typ). Ceramic capacitors ≥100pF are recommended; avoid low-leakage types <10nA leakage.
Does MAX16910DASA9+ include short-circuit and thermal protection?
Yes, MAX16910DASA9+ includes both short-circuit current limiting (330mA typ) and thermal shutdown (+180°C trip, +25°C hysteresis). During sustained overload, the device cycles ON/OFF to limit average power dissipation. These protections are fully integrated and require no external components-ensuring robust operation in automotive fault environments without additional circuitry.
