Product details

Overview

VN5E050JTR-E from STMicroelectronics is a single-channel automotive high-side driver in PowerSSO-12 package, delivering 50 mΩ on-resistance, 27 A current limitation (typ), and integrated diagnostics including open-load detection (ON/OFF state), short-to-VCC indication, and thermal shutdown with auto-restart. It drives grounded resistive/inductive/capacitive loads in body control modules and lighting systems.

For engineers reviewing the VN5E050JTR-E datasheet, VN5E050JTR-E pinout, VN5E050JTR-E application, or VN5E050JTR-E equivalent, key selection criteria include its 4.5–28 V operating range, 2 µA standby current, CMOS-compatible 3.0 V input logic, reverse-battery protection support, and ISO 7637-2 pulse immunity for automotive environments.

Technical Context

The device implements active power limitation for inrush and overload management, using VIPower M0-5 technology to self-limit fast thermal transients and sustain repeated short-circuit events without latch-up. Its diagnostic architecture features an open-drain STATUS pin with programmable disable via STAT_DIS and supports wired-OR configuration with other drivers.

Protection functions include undervoltage shutdown (4.5 V threshold), overvoltage clamp (41–52 V), load current limitation (19–38 A), and overtemperature shutdown at 150 °C with 135 °C restart hysteresis. All protections feed real-time status signals without external components.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load dump transients per ISO 7637-2 Pulse 5b up to +87 V with external clamp.
Operating voltage range	4.5 V to 28 V - supports full automotive battery range including cold-crank (4.5 V) and alternator regulation (28 V).
On-state resistance	50 mΩ (typ, 25°C) - enables low conduction loss (<1 W at 10 A), reducing thermal stress in compact PCB layouts.
Current limitation	27 A (typ) - limits fault energy during short-to-ground, enabling safe demagnetization of inductive loads up to 104 mJ.
Standby supply current	2 µA (typ, all loads connected) - meets stringent automotive quiescent current requirements for always-on modules.
Input logic compatibility	3.0 V CMOS - interfaces directly with 3.3 V microcontrollers without level-shifting, reducing BOM count.
Thermal shutdown	150 °C with auto-restart at 135 °C - provides fail-safe operation while maintaining system availability after transient overloads.

Pinout & Package

Package: PowerSSO-12 - thermally enhanced exposed-pad SOIC variant with integrated heat slug, optimized for automotive under-hood thermal environments (R_thj-case = 2.7 °C/W max).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail connection; supports 4.5–28 V operation and clamps transients up to 41 V.
OUTPUT	High-side power output	Drives grounded loads; integrates active voltage drop limitation (25 mV @ 0.1 A) for precise open-load sensing.
GND	Ground reference	Must be reverse-battery protected externally (diode/resistor network); referenced for all internal diagnostics.
INPUT	CMOS-compatible control input	Hysteretic 3.0 V logic interface (VIH = 2.1 V, VIL = 0.9 V); immune to noise in harsh automotive wiring harnesses.
STATUS	Open-drain diagnostic output	Reports overload, thermal shutdown, open-load (ON/OFF), and short-to-VCC; requires external pull-up for wired-OR capability.
STAT_DIS	Status enable/disable control	Active-high CMOS input (2.1 V threshold); disables STATUS pin to allow multi-driver status bus sharing.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents peak current surges during capacitive load turn-on, eliminating need for external NTC or soft-start circuitry.
Comprehensive open-load detection	Distinguishes ON-state (10–70 mA threshold) and OFF-state (2–4 V threshold) open circuits without external comparators or bias networks.
Short-to-VCC fault detection	Identifies output stuck-at-rail condition within 180–500 µs after INPUT deactivation, enabling rapid system-level fault isolation.
Reverse battery protection support	Internal GND path design allows external diode/resistor network to block -14 V reverse polarity without damaging the IC or load.
EMC-optimized switching	Controlled dV/dt (turn-on/off slope) and layout-aware PowerSSO-12 package reduce radiated emissions, easing ISO 11452-2/4 compliance.

Applications

Headlamp Control Module

Power Window Motor Driver

Use Scenario: Driving 12 V halogen or LED headlamps with PWM dimming and fault monitoring in A-pillar junction boxes.

IC Role / Device Role / Timing Role: High-side switch providing load isolation, inrush limiting, and real-time open-circuit/short-circuit feedback to MCU via STATUS pin.

Use Value: Eliminates discrete protection FETs and sense resistors; reduces PCB area by 35% vs. discrete solutions while meeting UNECE R128 thermal safety requirements.

Use Scenario: Controlling bidirectional DC motors in automotive power window lift mechanisms with stall detection and anti-pinch logic.

IC Role / Device Role / Timing Role: Dual-role high-side driver (forward/reverse via H-bridge companion) with fast (<200 µs) open-load reporting during motor commutation pauses.

Use Value: Enables reliable stall detection without current-sense amplifiers; STATUS timing aligns with MCU ADC sampling windows for synchronized fault logging.

Seat Heater Management

Engine Cooling Fan Interface

Use Scenario: Switching PTC heating elements in premium seat systems with thermal derating and open-wire detection across 10+ heater zones.

IC Role / Device Role / Timing Role: Load driver with auto-restarting thermal shutdown and OFF-state open-load detection to verify heater continuity before each activation cycle.

Use Value: Prevents false "heater fault" alerts caused by intermittent connections; 2 µA quiescent current avoids battery drain during vehicle sleep mode.

Use Scenario: Directly driving 12 V brushless cooling fans in engine bays where ambient temperature exceeds 105 °C and EMI is severe.

IC Role / Device Role / Timing Role: High-current (27 A peak) high-side switch with integrated overvoltage clamp and ISO 7637-2 Pulse 5b immunity up to +87 V.

Use Value: Withstands alternator load dump without external TVS; PowerSSO-12 thermal performance sustains 100% duty cycle at 85 °C ambient without derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (160 mΩ), lower ILIM (10 A), no OFF-state open-load detection.	Suitable for lower-power solenoid/valve control but lacks diagnostic depth for lighting or motor loads.	Select when cost sensitivity outweighs diagnostic completeness and thermal performance is less critical.
IPS1031H	Same PowerSSO-12 package, 35 mΩ R_ON, but only ON-state open-load detection and no STAT_DIS pin.	Supports simpler diagnostics but cannot share STATUS bus or disable diagnostics dynamically.	Choose for space-constrained designs needing lower on-resistance but accepting reduced diagnostic flexibility.

Compared with TPS4H160-Q1 and IPS1031H, VN5E050JTR-E uniquely combines 50 mΩ conduction loss, full ON/OFF open-load detection, and programmable STATUS disable-making it optimal for safety-critical body electronics requiring layered fault coverage and thermal resilience.

FAQ

What is the maximum continuous output current rating for VN5E050JTR-E?

The device has no fixed continuous current rating due to thermal dependence; its 27 A current limit (typ) is active during faults. Continuous current is determined by PCB copper area, ambient temperature, and thermal resistance. At 25 °C ambient with 200 cm² double-sided copper, it supports ~12 A continuous in PowerSSO-12 package per Figure 36 and Table 4.

Does VN5E050JTR-E require external components for reverse battery protection?

Yes - the GND pin must be protected externally using either a series resistor (RGND) or Schottky diode (DGND) as shown in Section 3.1 of the datasheet. The IC itself is not reverse-battery tolerant on GND; this external network prevents damage during -14 V polarity reversal.

How does the STATUS pin behave during thermal shutdown?

When junction temperature exceeds 150 °C, STATUS goes low after a 20 µs delay (tSDL) and remains low until temperature drops below 135 °C, at which point it returns high after thermal reset. This behavior is independent of INPUT state and is documented in Table 8 and Figure 4.

Can VN5E050JTR-E drive inductive loads without external flyback diodes?

No - an external freewheeling diode must be placed across the inductive load (cathode to VCC, anode to OUTPUT) to handle demagnetization energy. The device's V_DEMAG clamp (VCC−41 V) is not intended as primary flyback protection; it only limits voltage during controlled turn-off per Figure 34.
