Product details

Overview

VNL5090N3TR-E from STMicroelectronics is an AEC-Q100-qualified, fully protected low-side driver IC for automotive resistive/inductive loads, featuring 90 mΩ R_DS(on), 13 A continuous drain current, 41 V overvoltage clamp, thermal shutdown with auto-restart, and <1 µA standby current. It drives 2×R10W or 4×R5W signal lamps in battery-connected configurations.

For engineers reviewing the VNL5090N3TR-E datasheet, VNL5090N3TR-E pinout, VNL5090N3TR-E application, or VNL5090N3TR-E equivalent, key selection criteria include its integrated power limitation, fast demagnetization capability (t_f = 2.7 µs), ESD-hardened design (5 kV HBM), and SOT-223 package thermal performance on 2-layer PCBs (R_thj-amb ≈ 45 °C/W).

Technical Context

This monolithic VIPower® device integrates a PowerMOS output stage with embedded protection logic: active power limitation limits dissipated energy during sustained overload, while thermal shutdown (T_TSD = 150–200 °C) triggers automatic recovery upon fault clearance. The input section features CMOS-compatible hysteresis (V_IN(th) = 1–3.5 V, V_hyst = 0.13 V) and internal V_SUPPLY connection.

Unlike the VNL5090S5-E variant, the N3TR-E omits status reporting and open-load detection-its diagnostic function is limited to inherent thermal and current limiting behavior. Protection activation is fully autonomous: no external control or feedback is required for overtemperature, short-circuit, or overvoltage events.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	90 mΩ at 1.6 A, 25°C - enables low conduction loss in high-current lamp drivers
I_D (continuous)	13 A - supports dual R10W or quad R5W automotive signal lamps
V_CLAMP	41 V - clamps inductive kickback to protect against load dump transients
t_f (fall time)	2.7 µs - ensures rapid demagnetization of inductive loads (e.g., solenoids, relays)
I_SS (standby)	<1 µA - minimizes quiescent current in always-on vehicle modules
ESD rating	5 kV HBM (DRAIN–SUPPLY/INPUT) - meets automotive system-level ESD robustness requirements
T_j operating range	−40 to +150 °C - qualified for under-hood and exterior lighting environments

Pinout & Package

The VNL5090N3TR-E is housed in a thermally enhanced SOT-223 package with exposed drain pad for PCB heat sinking. Pin 1 (INPUT) accepts CMOS-level control signals; Pin 2 (GND/SOURCE) serves as both power MOSFET source and control ground reference; Pin 3 (DRAIN) connects to the load; Pin 4 (exposed pad) is internally connected to DRAIN and must be soldered to a copper heatsink area.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (INPUT)	CMOS-compatible control input with hysteresis	Drives internal logic; internally tied to V_SUPPLY; requires no external pull-up
Pin 2 (SOURCE)	Power MOSFET source and control ground reference	Common return path for load current and internal circuitry; must be low-impedance
Pin 3 (DRAIN)	Power MOSFET drain terminal	Connects to load; electrically tied to exposed thermal pad; carries full load current
Pin 4 (Exposed Pad)	Thermal and electrical connection to DRAIN	Must be soldered to ≥2 cm² copper pour for R_thj-amb ≤ 45 °C/W in 2-layer PCBs

Key Features

Feature	Design Value
Integrated overvoltage clamp	41 V clamping threshold prevents damage from inductive flyback without external TVS
Autonomous thermal shutdown	150–200 °C trip range with hysteresis (7 °C) and self-recovery avoids manual reset
Active power limitation	Reduces I²R dissipation during overload to prevent thermal runaway before shutdown
Ultra-low electromagnetic susceptibility	Validated immunity to automotive-level conducted/radiated noise per ISO 11452
AEC-Q100 Grade 1 qualification	Guarantees operation from −40 to +125 °C ambient (150 °C junction) for engine bay use

Applications

Automotive Signal Lamps

Use Scenario: Driving two R10W parking lamps or four R5W side-marker lamps from a 12 V battery rail.

IC Role / Device Role / Timing Role: Low-side switch controlling lamp current path; handles inrush and thermal cycling during repeated flash cycles.

Use Value: 13 A rating and 41 V clamp eliminate need for external flyback diodes or TVS devices in lamp circuits.

Use Scenario: Controlling solenoid valves and small relays in door lock, window lift, or mirror adjustment modules.

IC Role / Device Role / Timing Role: Load driver with fast turn-off (t_f = 2.7 µs) enabling precise demagnetization timing for mechanical actuation.

Use Value: Integrated power limitation prevents latch-up during solenoid coil saturation faults without MCU intervention.

Engine Bay Sensors

Trailer Tow Module Outputs

Use Scenario: Powering temperature or pressure sensors requiring stable 12 V bias in high-ambient-temperature zones.

IC Role / Device Role / Timing Role: Protected supply switch ensuring sensor power integrity during load dump (ISO 7637-2 Pulse 5a).

Use Value: 5 kV HBM ESD rating and 41 V clamp maintain functionality during electrostatic discharge events near engine components.

Use Scenario: Switching trailer brake lights, turn signals, and reverse lamps across variable cable lengths and connector resistances.

IC Role / Device Role / Timing Role: Robust low-side driver tolerant of long-wire inductance and intermittent connections.

Use Value: Thermal shutdown with auto-restart recovers lamp operation after trailer short-circuit faults without vehicle ECU reset.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250TR	Higher R_DS(on) (150 mΩ), lower I_D (8 A), no overvoltage clamp	Limited to smaller lamps (e.g., single R5W); requires external TVS for inductive loads	Select when cost sensitivity outweighs clamp integration and 13 A capacity
INFINEON BTS7008-1EPA	Higher standby current (20 µA), wider V_DS range (42 V), no AEC-Q100 Grade 1	Not rated for continuous 150 °C junction operation; unsuitable for under-hood placement	Prefer only for cabin-mounted modules where ambient temperature stays below 85 °C

Compared with STSPIN250TR and BTS7008-1EPA, the VNL5090N3TR-E delivers superior thermal resilience (150 °C T_j max), lower conduction loss (90 mΩ), and autonomous overvoltage protection-making it the only option qualified for direct engine-compartment mounting in multi-lamp driving applications.

FAQ

What is the maximum inductive load energy the VNL5090N3TR-E can safely demagnetize?

The device supports up to 50 mJ single-pulse avalanche energy (E_AS) at T_j = 150 °C with L = 1.1 mH. Its fast fall time (2.7 µs) and 41 V clamp enable reliable turn-off of solenoids and relays up to 13 A without external snubbers-verified per Figure 9 in DS8791 Rev 10.

Does the VNL5090N3TR-E require an external pull-up resistor on the INPUT pin?

No. The INPUT pin is internally connected to V_SUPPLY (5 V), making it self-biased for CMOS-compatible logic drive. External pull-ups are unnecessary and may interfere with hysteresis thresholds (V_IN(th) = 1–3.5 V, V_hyst = 0.13 V), as confirmed in Table 8 of the datasheet.

Can the VNL5090N3TR-E be used in 24 V commercial vehicle systems?

No. Its absolute maximum V_DS is internally clamped at 41 V, and it is specified only for 12 V automotive battery systems (V_CC = 13 V typical). For 24 V applications, ST recommends the VNL5030N3TR-E (60 V clamp) or BTS7008-1EPA (42 V rating), neither of which is AEC-Q100 Grade 1 qualified.

How does the thermal shutdown behavior differ between VNL5090N3TR-E and VNL5090S5TR-E?

Both variants share identical thermal shutdown thresholds (T_TSD = 150–200 °C) and hysteresis (7 °C), but only the S5TR-E exposes STATUS pin feedback for external monitoring. The N3TR-E performs autonomous restart without status signaling-its recovery is silent and immediate upon junction cooling below reset temperature, per Section 2.3 and Table 14.
