Product details

Overview

VNL5300S5TR-E from STMicroelectronics is a monolithic low-side driver IC built on VIPower® technology, designed to switch resistive or inductive loads connected to battery rails in automotive and industrial control systems. It delivers 2 A continuous drain current, features integrated overvoltage clamping (41 V), thermal shutdown with automatic restart, current/power limitation, and an open-drain status output for diagnostics.

For engineers reviewing the VNL5300S5TR-E datasheet, VNL5300S5TR-E pinout, VNL5300S5TR-E application, or VNL5300S5TR-E equivalent, this device serves as a robust, AEC-Q100 qualified load switch for solenoids, relays, lamps, and actuators where fault resilience, fast demagnetization, and precise diagnostic feedback are required.

Technical Context

The VNL5300S5TR-E integrates a PowerMOS output stage with active power limitation and thermal cycling protection: when overload persists, it dynamically reduces dissipated power to maintain junction temperature below 150 °C, then auto-restarts upon cooling. Its input features CMOS-compatible logic with 0.13 V hysteresis and internal clamp diodes (±0.7 V) for ESD robustness.

The status pin provides real-time fault reporting - pulled low during overtemperature, open-load, or undervoltage conditions - and supports configurable external pull-up. The device achieves fast switching (typ. 8 µs turn-on, 12 µs turn-off) and handles up to 26 mJ single-pulse avalanche energy, enabling reliable operation with inductive loads up to 19 mH.

Key Specifications

Parameter	Value and Actual Design Meaning
Drain Current (ID)	2 A continuous - supports medium-power solenoids and relays without external heatsinking under typical PCB layouts.
R_DS(on)	300 mΩ at 25 °C - minimizes conduction loss and self-heating during sustained ON-state operation.
V_CLAMP	41 V (typ.) - clamps inductive kickback to protect downstream circuitry and enable compact snubberless designs.
Thermal Shutdown Threshold	150 °C (typ.) - triggers automatic power reduction and recovery cycle to sustain functionality after transient overloads.
Status Output Logic	Open-drain, low-active - directly interfaces with 3.3 V/5 V MCU GPIOs for fault detection without level-shifting.
Input Hysteresis	0.13 V - prevents noise-induced toggling on marginal logic transitions in electrically noisy vehicle environments.
ESD Rating	±5000 V HBM (DRAIN–SUPPLY/INPUT/STATUS) - exceeds IEC 61000-4-2 Level 4 for robust system-level EMC compliance.

Pinout & Package

Delivered in SO-8 package (4.9 × 6.0 × 1.25 mm), the VNL5300S5TR-E uses standard surface-mount footprint with exposed thermal pad (pin 8) for enhanced PCB heat dissipation. Thermal resistance R_thJ-Amb is 53.8 °C/W on 4-layer PCB per JEDEC JESD51-2.

Pin/Terminal	Circuit Role	Design Meaning
INPUT	CMOS-compatible logic input	Hysteresis-enabled control signal; accepts 0–5 V levels; internal clamp limits voltage to ±0.7 V.
DRAIN	PowerMOS drain terminal	High-current switched output; connects to load high-side; clamped to 41 V during inductive flyback.
SOURCE	PowerMOS source & ground reference	Common return path for load current and internal control circuitry; tied to system GND.
SUPPLY	Logic supply input	5 V ±10% rail for internal biasing; includes 5.5 V clamp to prevent overvoltage damage.
STATUS	Open-drain diagnostic output	Active-low fault indicator; sinks current during overtemperature, open-load, or undervoltage events.

Key Features

Feature	Design Value
AEC-Q100 qualified	Qualified for automotive applications (Grade 1: −40 °C to +125 °C ambient), supporting under-hood and chassis-mounted control modules.
Integrated power limitation	Reduces output current to ~1.4 A during prolonged overload, limiting junction temperature rise without latching off.
Fast demagnetization support	Enables rapid energy dissipation from inductive loads (e.g., fuel injectors, valves) with <12 µs turn-off delay and 7 µs fall time.
Very low standby current	10 µA max OFF-state supply current - critical for always-on automotive modules requiring ultra-low quiescent power.
Open-load detection	Identifies disconnected loads via STATUS pin within 45–1100 µs after INPUT deactivation, improving system diagnostics fidelity.

Applications

Motorcycle Lighting System

Commercial HVAC Actuator Driver

Use Scenario: Switching LED headlight arrays and turn signal loads subject to wide battery voltage swings (9–16 V) and vibration-induced transients.

IC Role / Device Role / Timing Role: Battery-connected low-side driver with ESD-hardened inputs and clamped outputs for harsh electrical environments.

Use Value: Withstands 5000 V HBM ESD and 41 V clamp ensures lamp driver reliability without external TVS, lowering BOM cost.

Use Scenario: Driving damper and valve actuators in rooftop HVAC units exposed to temperature extremes and long cable runs.

Use Value: STATUS pin confirms load connectivity before command execution, preventing false "valve open" assertions in building management systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Integrated current regulation (not just limitation); no status pin; 1.5 A max continuous current.	Targeted at stepper motor microstepping, not general-purpose load switching.	Choose only if closed-loop current control is required and diagnostic reporting is unnecessary.
Infineon BTS50085-1TAD	Higher current rating (8.5 A), larger PG-TO263-7 package, dual-channel configuration.	Designed for high-power body electronics (e.g., seat motors, window lifts); lacks SO-8 footprint compatibility.	Select when >2 A drive capability and dual-output integration are mandatory; not drop-in compatible.

Compared with STSPIN250 and BTS50085-1TAD, the VNL5300S5TR-E uniquely balances SO-8 compactness, 2 A capability, full diagnostic status reporting, and automotive-grade protection - making it optimal for space-constrained, single-channel, safety-aware control nodes.

FAQ

What is the maximum inductive load energy the VNL5300S5TR-E can safely demagnetize?

The device supports up to 26 mJ single-pulse avalanche energy (EAS) with L = 19 mH, Tj = 150 °C, and RL = 0 Ω. For repetitive demagnetization, peak junction temperature must remain below 125 °C at pulse start, and energy per pulse must be reduced per Figure 6 in the datasheet to avoid cumulative thermal stress.

Does the STATUS pin require an external pull-up resistor?

Yes - the STATUS pin is open-drain and requires an external pull-up resistor (typically 4.7–10 kΩ to 5 V) to generate a valid high-level signal during normal operation. Without it, the pin remains floating and cannot indicate fault-free status reliably.

Can the VNL5300S5TR-E drive loads directly from a 24 V supply?

No - its SUPPLY pin is rated for 3.5–5.5 V only, and DRAIN voltage is clamped at 41 V. While DRAIN can tolerate 24 V battery transients, the logic section must be powered separately from a regulated 5 V rail; direct 24 V connection to SUPPLY will destroy the IC.

How does thermal shutdown recovery work during sustained overload?

Upon reaching 150 °C, the device enters thermal cycling: it reduces output current to ~1.4 A, holds until junction cools to ~135 °C (TRS), then resumes full 2 A operation. This hysteresis (7 °C) prevents oscillation and allows gradual recovery without MCU intervention or power cycle.
