Product details

Overview

VN5050JTR-E from STMicroelectronics is a single-channel automotive high-side driver IC designed for controlling resistive, inductive, and capacitive loads connected to ground. It features 50 mΩ on-state resistance (R_ON), 19 A typical current limitation (I_LIMH), 4.5–36 V operating supply range, and integrated open-load detection in both ON/OFF states. It is used in body control modules for headlight, fog light, and HVAC blower switching.

For engineers reviewing the VN5050JTR-E datasheet, VN5050JTR-E pinout, VN5050JTR-E application, or VN5050JTR-E equivalent, this page delivers verified electrical specs, diagnostic behavior, thermal shutdown timing, ISO7637-2 transient compliance, and real-world load-driving context - all critical for automotive power distribution design validation.

Technical Context

The VN5050JTR-E integrates VIPower M0-3 technology to combine power MOSFET, protection logic, and diagnostics in one monolithic high-side switch. Its active power limitation manages inrush current without external components, while dual-mode open-load detection (using STATUS pin state and STAT_DIS control) enables robust fault reporting across ignition cycles.

It implements undervoltage lockout (4.5 V threshold), overvoltage clamp (41–52 V), reverse-battery protection via external GND network, and thermal shutdown with automatic restart at 150 °C. The CMOS-compatible 3.0 V logic input and open-drain STATUS output interface directly with automotive microcontrollers without level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	4.5 V to 36 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump transients (up to 36 V continuous).
R_ON (typ)	50 mΩ at 25 °C - enables <1 W conduction loss at 10 A, reducing heatsink requirements in compact BCM layouts.
I_LIMH (typ)	19 A - limits short-circuit energy during faults while sustaining brief inrush peaks for lamps and motors.
Open-load Detection	ON-state: detects I_OUT < 10–50 mA; OFF-state: detects V_OUT > 2–4 V - eliminates need for external sense resistors or ADC monitoring.
STATUS Pin	Open-drain with 0.5 V max low-level voltage at 1.6 mA - compatible with 3.3 V/5 V MCU GPIOs and supports wired-OR diagnostics across multiple channels.
ISO7637-2 Compliance	Class C for pulses 1, 2a, 3a, 3b, 4, and 5b - withstands automotive transients without latch-up or functional interruption.
Thermal Shutdown	Triggers at 150 °C junction temperature with 135 °C auto-restart hysteresis - prevents permanent damage during sustained overload or poor PCB copper area.

Pinout & Package

Package: PowerSSO-12™ (exposed thermal pad, surface-mount, 12-pin). Pin #1 and #6 are V_CC; pins #7 and #12 are OUTPUT; pins #3 and #8 are GND; pin #4 is INPUT; pin #5 is STATUS; pin #9 is STAT_DIS. Unused pins (N.C.) must be left floating or pulled via 10 kΩ resistor per ST recommendation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC (Pins 1, 6)	Battery supply input	Dual V_CC pins reduce trace inductance and improve transient immunity; clamped to 41–52 V internally.
OUTPUT (Pins 7, 12)	High-side switched output	Parallel outputs increase current capability and thermal spreading; each channel rated for 19 A short-circuit limit.
GND (Pins 3, 8)	Ground reference	Dual GND pins minimize ground bounce; requires external reverse-battery protection network per Figure 27.
INPUT	CMOS logic control input	3.0 V compatible with 3.3 V MCUs; 0.25 V hysteresis prevents noise-induced switching near threshold.
STATUS	Diagnostic open-drain output	Reports open-load, overtemperature, undervoltage, and short-to-V_CC; pulled high externally for active-low signaling.
STAT_DIS	Status disable control	Active-high CMOS input; drives STATUS into high-impedance when asserted - enables shared diagnostic bus architecture.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage droop and EMI spikes during lamp/motor turn-on without external RC snubbers.
Low quiescent current	2 µA off-state supply current - meets automotive "always-on" module leakage budgets for battery-sensitive applications.
Integrated diagnostics	Single-pin STATUS reports four distinct fault types (open-load ON/OFF, thermal shutdown, undervoltage) with defined timing delays (t_DOL(on), t_SDL).
Reverse battery protection support	Internal circuitry tolerates reverse V_CC down to –0.3 V; external diode/resistor GND network (per Figure 27) extends protection to –14 V.
EMC-optimized layout	PowerSSO-12™ package with exposed thermal pad and symmetrical V_CC/GND pin pairing minimizes loop area and radiated emissions.

Applications

Use Value: Sustains repeated stall events without latch-up; STATUS pin alerts MCU before thermal shutdown, enabling graceful fan ramp-down.

Front Fog Light Activation

Seat Heater Power Distribution

Use Scenario: Switching 35–55 W fog lights with load dump immunity and open-wire detection during vehicle startup.

IC Role / Device Role / Timing Role: Fault-tolerant power switch with ISO7637-2 Class C compliance and OFF-state open-load detection (V_OL = 2–4 V threshold).

Use Value: Detects broken bulb filaments or corroded connectors before driver activation - prevents false "lamp out" warnings in dashboard cluster.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS50080-1TAD	Lower R_ON (3.5 mΩ), higher I_LIM (80 A), no integrated open-load OFF-state detection.	Targeted at high-power solenoids and starter relays; lacks diagnostic granularity for low-current lamp monitoring.	Select when peak current >30 A is required and diagnostics are handled externally via current sensing.
NXP MC33883	8-bit SPI interface, programmable slew rate, no integrated V_CC clamp; requires external TVS for load dump.	Designed for daisy-chained multi-channel systems with centralized MCU control; not pin-compatible.	Choose for scalable, software-configurable power distribution where board space allows additional passive protection.

Compared with VN5050JTR-E, BTS50080-1TAD offers superior conduction efficiency but sacrifices diagnostic completeness, while MC33883 provides configurability at the cost of increased component count and layout complexity - making VN5050JTR-E optimal for cost-sensitive, single-channel automotive lighting and heating applications requiring embedded diagnostics.

FAQ

What is the maximum continuous output current rating for VN5050JTR-E?

The VN5050JTR-E does not specify a continuous current rating independent of thermal conditions. Its safe operating current depends on PCB copper area, ambient temperature, and airflow. At T_j = 150 °C with R_thj-amb = 30 °C/W (Figure 31), it sustains ~4.5 A continuously. For 10 A+ operation, use minimum 200 cm² double-sided copper with thermal vias to the exposed pad.

How does open-load detection work in OFF state, and what external components are needed?

OFF-state open-load detection triggers when V_OUT exceeds 2–4 V (measured relative to GND) while INPUT is low and STAT_DIS is low. No external components are required - the internal current source pulls V_OUT up through the load impedance. If the load is disconnected, V_OUT rises above the threshold and STATUS goes low after t_DOL(on) ≈ 200 µs.

Can VN5050JTR-E drive inductive loads like fuel pumps without external flyback diodes?

No. While the device includes V_DEMAG clamping (V_CC − 41 V) to absorb demagnetization energy, this is rated for ≤104 mJ (L = 3 mH, V_bat = 13.5 V). Fuel pumps typically require >500 mJ suppression. An external flyback diode (e.g., STTH1R06) across the load is mandatory to prevent V_CC rail collapse and ensure reliable turn-off.

Is the PowerSSO-12™ package RoHS-compliant and lead-free?

Yes. VN5050JTR-E uses ST's ECOPACK®2-compliant PowerSSO-12™ package, fully lead-free and RoHS-compliant per Directive 2011/65/EU. The exposed thermal pad is solderable with standard SnAgCu reflow profiles (peak 260 °C), and JEDEC moisture sensitivity level is MSL3.
