Product details

Overview

VND5E025BKTR-E from STMicroelectronics is a dual-channel automotive high-side driver in PowerSSO-24 package, delivering 25 mΩ on-resistance per channel, 60 A current limiting, and analog current sense with ±9.5% single-point calibration drift. It drives grounded resistive/inductive/capacitive loads-including LED blinkers-with 3.0 V CMOS-compatible inputs and integrated diagnostics for overload, short-to-ground, and overtemperature events.

For engineers reviewing the VND5E025BKTR-E datasheet, VND5E025BKTR-E pinout, VND5E025BKTR-E application, or VND5E025BKTR-E equivalent, key selection criteria include its dual-channel high-side topology, 4.5–28 V operating range, thermal shutdown with auto-restart, reverse-battery protection support, and per-channel analog current sense with CS_DIS disable control.

Technical Context

The device implements active power limitation for inrush and overload management via dynamic output voltage drop control (VON ≤ 25 mV at 0.1 A) and thermal foldback, enabling robust operation under sustained fault conditions. Its VIPower™ M0-5 process integrates high-voltage DMOS outputs with CMOS logic, supporting 3 V/5 V microcontroller interfacing without level shifters.

Each channel features independent analog current sense (K = 2460–4050 typ. IOUT/ISENSE at 1.5 A), with dK/K(tot) drift as low as ±7% across temperature and load for single-point calibration. The CS_DIS pin enables shared external sense resistor usage across multiple devices by disabling internal sense circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load-dump transients without external clamp
Operating voltage	4.5 to 28 V - supports full 12 V battery range including cold-crank (4.5 V) and alternator regulation (up to 28 V)
R_ON (per ch.)	25 mΩ typ. at 25°C - enables <1 W conduction loss at 20 A, reducing heatsink requirements
Current limit (ILIMH)	60 A typ. - sustains short-circuit events while limiting peak power dissipation
Standby current	2 µA typ. - meets automotive ISO 8859-3 quiescent current requirements for always-on modules
Current sense ratio	3363 typ. (IOUT/ISENSE at 1.5 A) - delivers ~448 µA sense current at 1.5 A load for precise ADC sampling
Thermal shutdown	150°C trigger with 135°C reset - provides safe auto-recovery after transient overloads without MCU intervention

Pinout & Package

Housed in the thermally enhanced PowerSSO-24 package with exposed VCC tab for PCB heat spreading, the device uses a 24-pin surface-mount configuration with dual-channel symmetry and dedicated diagnostic pins.

Pin/Terminal	Circuit Role	Design Meaning
VCC (Pins 4, 12, TAB)	Main supply input	High-current path feeding both channels; TAB must be soldered to large copper pour for thermal management
OUTPUT1/2 (Pins 13–18, 19–24)	High-side switched outputs	Parallel-pin configuration per channel for low-inductance, high-current routing to grounded loads
INPUT1/2 (Pins 6, 11)	CMOS-compatible control inputs	3.0 V logic compatible with automotive MCUs; 0.25 V hysteresis prevents noise-induced switching
CURRENT SENSE1/2 (Pins 8, 10)	Analog current feedback outputs	Current-source outputs proportional to load current; require external 3.9 kΩ pull-up for voltage-mode sensing
CS_DIS (Pin 7)	Current sense enable/disable	Active-high logic input; pulling high disables both sense channels to share one external sense resistor
GND (Pin 3)	Ground reference	Must be protected against reverse battery via external diode/resistor network per datasheet Figure 3

Key Features

Feature	Design Value
Inrush current management	Active power limitation dynamically controls dV/dt during turn-on to prevent fuse blowing and EMI spikes
Single-point calibration	dK/K(tot) ≤ ±7% enables factory calibration at one load point (2.4 A), eliminating multi-point test overhead
Reverse battery protection	Integrated GND protection network compatibility allows simple external diode/resistor solution (no additional ICs required)
Diagnostic sharing	CS_DIS pin enables multiplexed current sensing across multiple VND5E025BKTR-E devices using one external resistor
Auto-recovering thermal shutdown	150°C trip with 135°C hysteresis ensures temporary overloads clear without system reset or firmware intervention

Applications

Automotive Turn Signals

LED Headlamp Dimming

Use Scenario: Driving sequential LED blinker arrays in front/rear lighting modules with PWM dimming and fault reporting.

IC Role / Device Role / Timing Role: Dual high-side switch controlling left/right ground-return LED strings; current sense feeds MCU for open-load and short-circuit detection.

Use Value: 25 mΩ R_ON minimizes voltage drop across headlamp strings, preserving luminance uniformity at low battery voltage (4.5 V).

Use Scenario: Managing high-power LED headlamps with adaptive driving beam (ADB) segmentation requiring independent channel control.

IC Role / Device Role / Timing Role: High-side driver for individual LED zones; thermal shutdown with auto-restart maintains partial illumination during intermittent overloads.

Use Value: 60 A current limit supports brief inrush of multi-LED arrays during cold start, avoiding false fault triggers.

Engine Control Solenoids

Body Control Module Loads

Use Scenario: Switching fuel injector solenoids and turbocharger vanes in engine management systems with real-time current monitoring.

IC Role / Device Role / Timing Role: High-side driver with fast current sense response (<300 µs) for closed-loop solenoid current profiling and demagnetization energy control.

Use Value: VDEMAG clamp (VCC − 41 V) limits flyback voltage during turn-off, protecting the MOSFET without external snubbers.

Use Scenario: Controlling door locks, window motors, and HVAC actuators in centralized body control units with diagnostic logging.

IC Role / Device Role / Timing Role: Dual-channel load driver with shared CS_DIS and per-channel sense for BOM consolidation and fault isolation.

Use Value: 2 µA standby current enables always-on BCM functionality while meeting OEM sleep-mode leakage budgets.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5E025AJTR-E	Same architecture but PowerSSO-36 package; higher R_ON (35 mΩ typ.), lower ILIMH (45 A)	Targeted at less thermally constrained layouts; reduced current capability limits use in high-power LED or solenoid loads	Select when board space permits larger package and peak load currents remain below 45 A
BTS724G	Single-channel, SO-16 package; 30 mΩ R_ON; no analog current sense - only digital fault flag	Requires two devices for dual-channel function; lacks per-channel analog diagnostics needed for precise current profiling	Choose for cost-sensitive, non-diagnostic applications where channel independence is not required

Compared with VND5E025AJTR-E and BTS724G, the VND5E025BKTR-E uniquely combines dual-channel integration, 25 mΩ conduction, analog current sense with single-point calibration, and PowerSSO-24 thermal efficiency-making it optimal for space-constrained, high-diagnostic automotive modules.

FAQ

What is the maximum continuous output current per channel?

The VND5E025BKTR-E does not specify a continuous current rating independent of thermal conditions. Its 60 A current limit (ILIMH) is a short-circuit protection threshold. Continuous current depends on PCB copper area, ambient temperature, and switching duty cycle - with typical derated values of 12–18 A achievable using the PowerSSO-24 thermal pad and 200 cm² copper pour per channel.

How does the current sense ratio drift affect calibration accuracy?

The dK/K(tot) drift of ±7% at 2.4 A enables single-point calibration across -40°C to +150°C without multi-point compensation. This reduces production test time and eliminates need for temperature chambers during calibration, while maintaining ±3% current measurement error at 1.5–4 A loads when calibrated at 2.4 A.

Can CS_DIS be used to disable only one channel's current sense?

No. The CS_DIS pin globally disables both CURRENT SENSE1 and CURRENT SENSE2 channels simultaneously. There is no per-channel sense disable function; separate sense resistor networks or external multiplexing are required for independent channel sensing control.

Is reverse battery protection built-in or external?

Reverse battery protection is not fully integrated - the device requires an external protection network on the GND pin (e.g., series diode or resistor) as specified in Section 3.1 of the datasheet. The internal structure tolerates reverse GND but relies on external components to limit reverse current to safe levels (<200 mA).
