Product details

Overview

VND5E050ACKTR-E from STMicroelectronics is a double-channel high-side driver IC for 12 V automotive grounded loads, featuring integrated analog current sense per channel, 50 mΩ typical on-resistance, 27 A current limitation, and CMOS-compatible 3.0 V/5.0 V inputs. It delivers diagnostic feedback (open-load, short-to-VCC, overtemperature, overload) and protection (undervoltage shutdown, overvoltage clamp, reverse-battery tolerance) in PowerSSO-24 package.

For engineers reviewing the VND5E050ACKTR-E datasheet, VND5E050ACKTR-E pinout, VND5E050ACKTR-E application, or VND5E050ACKTR-E equivalent, key selection criteria include per-channel current sense ratio (2250 typ), thermal shutdown auto-restart behavior, PowerSSO-24 thermal resistance (2.7 °C/W junction-to-case), and compatibility with automotive microcontroller I/Os under load dump and ESD stress.

Technical Context

This device implements two independent VIPower® M0-5 high-side switches with active power limitation for inrush and overload management, each with dedicated analog current sense output (K₀ = 2250 typ) and configurable disable via CS_DIS. Diagnostics include off-state open-load detection, short-to-VCC indication, and thermal shutdown with 150 °C trip and 135 °C reset thresholds.

Protection architecture integrates undervoltage lockout (V_USD = 4.5 V typ), overvoltage clamp (41–52 V), self-limiting fast thermal transients, and reverse-battery resilience via external GND network. The PowerSSO-24 package enables dual-channel operation with shared thermal path and low-inductance layout for automotive EMC compliance.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load dump transients without external clamping
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and battery float (28 V) conditions
On-resistance (per ch.)	50 mΩ typ at 25°C - limits conduction loss to ≤100 mW at 1.4 A continuous load
Current limit (typ)	27 A - sustains short-circuit events while limiting peak power dissipation
Standby current	2 µA typ - enables always-on modules without battery drain
Current sense ratio	2250 typ (I_OUT/I_SENSE) - provides 0.444 mA sense current per 1 A load for precision ADC interfacing
Thermal shutdown	150 °C trip, 135 °C reset - enables auto-recovery after transient overloads without MCU intervention

Pinout & Package

Package: PowerSSO-24 (exposed thermal pad connected to VCC, RoHS-compliant, ECOPACK®).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed thermal pad for enhanced heat dissipation
GND	Ground reference	Must be protected against reverse battery via external diode/resistor network per datasheet Figure 31
INPUT1 / INPUT2	CMOS-compatible control inputs	3.0 V/5.0 V logic compatible; 0.9 V low / 2.1 V high thresholds with 0.25 V hysteresis
OUTPUT1 / OUTPUT2	High-side power outputs	Drive grounded resistive/inductive/capacitive loads; integrate reverse-battery diode (VF = 0.7 V @ 4 A)
CURRENT SENSE1 / CURRENT SENSE2	Analog current monitor outputs	Deliver proportional current (I_SENSE = I_OUT/2250) for real-time load monitoring and fault classification
CS_DIS	Current sense enable/disable	Active-high CMOS input; disables both sense channels when pulled ≥2.1 V, enabling shared external sense resistor

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents fuse blowing during capacitive load turn-on without external circuitry
Off-state open-load detection	Validated across full VCC (8–18 V) and temperature (-40 to 150 °C) range using internal bias current
Short-to-VCC diagnosis	Detects output shorted to battery during both on- and off-states via dedicated sensing path
EMC-optimized switching	Controlled dV/dt (see Figures 26/28) and layout-optimized PowerSSO-24 reduce radiated emissions in 12 V systems
Reverse battery protection	Withstands -0.3 V VCC and -200 mA GND current; requires external GND network per Section 3.1

Applications

Use Scenario: Controlling high-brightness LED arrays in adaptive front-lighting systems (AFS).

IC Role / Device Role / Timing Role: Precision current-regulated high-side driver with thermal foldback during overtemperature events.

Use Value: Maintains LED brightness stability across ambient temperatures (-40 to 125 °C case) via accurate 2250-ratio current mirroring.

Engine Bay Fan Controller

Electric Power Steering (EPS) Auxiliary Load Switch

Use Scenario: Managing 12 V DC brushless fan motors subject to high inductive kickback and load dump.

IC Role / Device Role / Timing Role: Robust high-side driver with demagnetization energy handling (up to 104 mJ) and V_DEMAG clamping.

Use Value: Prevents MOSFET avalanche failure during motor turn-off without snubber networks or TVS diodes.

Use Scenario: Switching safety-critical auxiliary loads (e.g., torque sensor heaters, EPS cooling pumps) in ASIL-B systems.

IC Role / Device Role / Timing Role: Diagnostic-enabled high-side switch with ISO 26262-ready fault reporting (short-to-VCC, open-load, thermal).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5E025AKTR-E	Lower R_ON (25 mΩ), lower ILIMH (18 A), same PowerSSO-24 package	Better for high-efficiency, lower-current (<10 A) loads; reduced thermal margin at 27 A	Select when conduction loss dominates over fault robustness
TPS2HB50-Q1	Single-channel, 50 mΩ R_ON, no analog current sense (digital fault flags only), HTSSOP-20	Lacks per-channel analog diagnostics; requires external ADC for current measurement	Select when space-constrained PCBs prioritize channel count over diagnostic granularity

Compared with VND5E050ACKTR-E, the VND5E025AKTR-E trades higher short-circuit robustness for lower conduction loss, while the TPS2HB50-Q1 reduces integration depth to fit tighter layouts but removes analog current visibility-critical for predictive maintenance in BCMs.

FAQ

What is the maximum continuous output current per channel?

The VND5E050ACKTR-E does not specify a continuous current rating due to thermal dependence on PCB copper area and airflow. At 25°C ambient with 100 cm² copper pour and free air, it supports ~5.5 A continuous per channel before thermal shutdown activates. Derating curves in Figure 36 confirm 3.2 A at 85°C ambient under identical conditions.

How does the current sense function behave during thermal shutdown?

During thermal shutdown, the current sense output remains active and proportional to actual load current until junction temperature exceeds 175°C (absolute max). The sense ratio drift stays within ±5% across -40°C to 150°C, enabling valid fault classification even during thermal limiting events.

Can CS_DIS be left floating?

No. Table 2 explicitly prohibits floating CS_DIS: it must be pulled to ground via a 10 kΩ resistor if unused. Floating causes undefined sense channel behavior and may trigger false diagnostics due to noise coupling on the high-impedance CMOS input.

Is reverse-battery protection internal or external?

Reverse-battery protection is partially internal (withstands -0.3 V VCC and -200 mA GND current) but requires an external GND protection network-either a series resistor (RGND) or diode (DGND)-to meet ISO 16750-2 requirements. Section 3.1 details both validated configurations.
