Product details

Overview

VND5050JTR-E from STMicroelectronics is a double-channel high-side driver IC for automotive power distribution, designed to control resistive, inductive, and capacitive loads connected to ground. It features 50 mΩ typical on-state resistance per channel, 18 A current limitation, 4.5–36 V operating supply range, and integrated open-load detection in both on- and off-states - enabling robust load monitoring in body control modules and lighting systems.

For engineers reviewing the VND5050JTR-E datasheet, VND5050JTR-E pinout, VND5050JTR-E application, or VND5050JTR-E equivalent, key selection criteria include its PowerSSO-12 package thermal performance, CMOS-compatible 3.0 V logic inputs, dual-channel diagnostic status outputs, and reverse-battery protection architecture compliant with ISO 7637 transient immunity requirements.

Technical Context

The device implements two independent VIPower M0-5 high-side switches with integrated current limiting, thermal shutdown with automatic restart, and bidirectional open-load detection using internal sense circuitry. Each channel provides active power limitation during inrush and overload, with output stuck-to-VCC detection triggered at turn-off.

Diagnostic functionality is managed via open-drain STATUS pins and an active-high STAT_DIS input that places STATUS in high-impedance mode. Protection features include undervoltage lockout (4.5 V threshold), VCC clamp up to 52 V, loss-of-ground/loss-of-VCC detection, and ESD robustness (4 kV HBM on all pins).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	4.5 V to 36 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump transients (clamped to 52 V)
On-state resistance (per ch.)	50 mΩ typ. at 2 A, 25°C - enables <1 W conduction loss at 10 A, reducing heatsink requirements
Current limitation	18 A typ. - limits fault energy during short circuits while sustaining operation until thermal shutdown intervenes
Standby supply current	2 µA max. - ensures ultra-low quiescent draw in always-on vehicle domains (e.g., alarm, CAN wake-up)
Open-load detection	On-state: 10–70 mA threshold; Off-state: 2–4 V threshold - enables reliable bulb-out and connector-disconnect diagnostics without external components
Thermal shutdown	150°C trigger, 135°C reset - provides safe self-recovery under sustained overload without latch-up
Input logic compatibility	3.0 V CMOS - interfaces directly with 3.3 V microcontrollers without level-shifting

Pinout & Package

Delivered in PowerSSO-12 surface-mount package with exposed thermal pad (TAB = VCC), optimized for PCB copper area heat spreading in automotive under-hood environments.

Pin/Terminal	Circuit Role	Design Meaning
INPUT1 / INPUT2	CMOS-compatible control input	Active-high logic inputs with 0.25 V hysteresis; drive channels independently with 1 µA leakage
OUTPUT1 / OUTPUT2	High-side power output	Drives grounded loads; includes VCC-clamp diode and fast demagnetization path for inductive kickback
STATUS1 / STATUS2	Open-drain diagnostic output	Reports open-load (on/off), overtemperature, and output-stuck-to-VCC faults; requires external pull-up
STAT_DIS	Status disable control	Active-high input disabling STATUS pins - used to suppress diagnostics during system initialization or sleep modes
VCC	Main supply connection	41 V absolute max; integrates clamp circuit protecting against ISO 7637-2 pulse 5a (load dump)
GND	Ground reference	Must be externally protected against reverse battery via resistor/diode network per Figure 28

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents fuse blowing during lamp/capacitor charging without external current-sense circuitry
EMI-optimized switching	Controlled dV/dt slew rates (Figure 22/24) reduce radiated emissions in sensitive infotainment and ADAS zones
Dual-state open-load detection	Validates load integrity whether powered (on-state) or de-energized (off-state), critical for fail-safe lighting control
Reverse battery protection support	Integrated GND protection network compatibility (Figure 28) enables robust design against -14 V reverse connection
ISO 7637-2 transient immunity	Clamp circuit withstands 5a load dump pulses up to 41 V without external TVS, simplifying BOM and layout

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5020AJTR-E	Lower R_ON (20 mΩ), single-channel, same PowerSSO-12 package	Better suited for high-current single-load applications (e.g., starter solenoid) but lacks dual-channel integration	Select when higher efficiency per channel is prioritized over channel count and board space
TPS4H160-Q1	4-channel, 160 mΩ R_ON, SPI-configurable diagnostics, QFN-24 package	Offers programmable current limit and fault masking via serial interface - adds MCU overhead but increases flexibility	Select when system-level configurability and channel scalability outweigh fixed-function simplicity and lower R_ON

Compared with VND5050JTR-E, VND5020AJTR-E delivers lower conduction loss but sacrifices dual-channel consolidation, while TPS4H160-Q1 trades analog simplicity for digital configurability and higher on-resistance - making VND5050JTR-E optimal for cost-sensitive, thermally constrained dual-load automotive nodes requiring deterministic analog behavior.

FAQ

What is the maximum continuous output current per channel?

The VND5050JTR-E does not specify a fixed maximum continuous current; instead, it uses thermal foldback to self-limit power dissipation. At 25°C ambient with 200 mm² PCB copper, it sustains ~10 A continuously before entering thermal regulation. Peak current is limited to 18 A (typ.) during short-circuit events, with automatic recovery after fault clearance.

How does open-load detection work in the off-state?

In off-state, the device applies a small test current (~10 µA) through the output to measure voltage drop across the load. If V_OUT exceeds 2–4 V (depending on V_CC), the STATUS pin asserts low after 200 µs delay, indicating an open circuit. This works without external biasing and remains functional even with disconnected loads.

Can STAT_DIS be left floating?

No - STAT_DIS must be actively driven high or low. Floating STAT_DIS causes undefined STATUS pin behavior due to internal hysteresis and may result in intermittent fault reporting. Table 3 recommends connecting unused STAT_DIS to ground via a 10 kΩ resistor if not used, but direct logic control is preferred for deterministic operation.

Is reverse battery protection built-in?

The VND5050JTR-E does not include internal reverse battery protection. Its GND pin requires external protection - either a series resistor (R_GND) or Schottky diode (D_GND) - as shown in Figure 28. This external network prevents damage during -14 V reverse connection while maintaining low forward voltage drop during normal operation.
