Product details

Overview

VND5E025AK-E from STMicroelectronics is a dual-channel automotive high-side driver in PowerSSO-24 package, delivering 25 mΩ on-state resistance per channel, 60 A typical current limitation, and analog proportional current sense per output. It drives 12 V grounded resistive/inductive/capacitive loads-including LEDs-with integrated diagnostics, reverse-battery protection, and 3.0 V/5.0 V CMOS-compatible inputs for microcontroller interfacing.

For engineers reviewing the VND5E025AK-E datasheet, VND5E025AK-E pinout, VND5E025AK-E application, or VND5E025AK-E equivalent, key selection criteria include its dual-channel high-side topology, ±13% current sense ratio drift over temperature, off-state open-load detection capability, and compliance with automotive transient requirements (ISO 7637-2, ISO 16750-2).

Technical Context

The device implements active power limitation for inrush and overload management via real-time current sensing and dynamic voltage drop control, enabling stable operation under fast thermal transients. Each channel features independent analog current sense (K₀ = 1860–4600 A/A typ.) with dedicated CS_DIS enable/disable control and fault reporting via voltage-clamped sense outputs.

Protection architecture includes undervoltage shutdown (4.5 V threshold), overvoltage clamp (41–52 V), thermal shutdown with auto-restart (150–200 °C trip), and loss-of-ground/VCC detection. Diagnostics cover short-to-VCC, off-state open-load, and overload indication-all mapped to analog sense pins without requiring external ADC polling overhead.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V DC - withstands load-dump transients up to ISO 16750-2 Level IV without external clamping.
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and battery-overvoltage (28 V) conditions in 12 V automotive systems.
On-state resistance	25 mΩ typ. at 25 °C - limits conduction loss to ≤225 mW at 3 A, enabling compact thermal design.
Current limit (typ)	60 A - provides robust short-circuit protection while allowing high peak inrush for solenoids and lamps.
Standby current	2 µA - enables always-on modules (e.g., body control units) without draining battery during sleep mode.
Current sense accuracy	±13% K-ratio drift over −40 °C to +150 °C - supports reliable fault classification across full automotive temperature range.
CS_DIS logic threshold	2.1 V high-level input - ensures compatibility with 3.3 V and 5 V MCU GPIOs without level-shifting.

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
VCC (Pins 4, 12, 24, TAB)	Battery supply input	Primary power rail; TAB is electrically tied to VCC for low-inductance thermal path and current delivery.
OUTPUT1 / OUTPUT2 (Pins 13–18, 19–23)	High-side power outputs	Two independent switched 12 V outputs; each capable of driving up to 60 A short-circuit current with internal limiting.
GND (Pin 3)	Ground reference	Reverse-battery protected ground node; requires external diode/resistor network per datasheet Figure 31.
INPUT1 / INPUT2 (Pins 6, 11)	Digital control inputs	CMOS-compatible with 0.9 V low / 2.1 V high thresholds and 0.25 V hysteresis-immune to noise in harsh automotive environments.
CURRENT SENSE1 / CURRENT SENSE2 (Pins 8, 10)	Analog diagnostic outputs	Deliver current-proportional I_SENSE (e.g., 3150 A/A typ. at 0.5 A); support external resistor sharing when CS_DIS is asserted.
CS_DIS (Pin 7)	Current sense disable control	Active-high signal disabling both sense channels simultaneously-enables multiplexed sensing in multi-driver systems.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage sag during lamp/solenoid turn-on, eliminating need for external soft-start circuitry.
Off-state open-load detection	Validates load continuity before activation using internal bias current-detects broken wires or disconnected bulbs without external components.
Short-to-VCC diagnosis	Identifies output shorted to battery via sense pin saturation-enables fail-safe shutdown before wire harness damage occurs.
Thermal shutdown with auto-restart	Resets after cooling below 135–140 °C-maintains system availability during intermittent overload without MCU intervention.
Reverse battery protection	Withstands −14 V applied to GND (with external network)-eliminates need for series diode in ground path, reducing power loss.

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
TPS4H160-Q1	Single-channel, 160 mΩ R_ON, no analog current sense-uses digital SPI diagnostics only.	Suitable for lower-power loads (<5 A); lacks proportional analog sense needed for precise LED dimming or solenoid characterization.	Select when system uses SPI-based diagnostics and thermal budget allows higher conduction loss.
VND7E025AJTR-E	Same VIPower M0-5 process but single-channel, 25 mΩ R_ON, identical sense architecture and protection set.	Requires two devices to match dual-channel functionality-increases footprint and BOM cost vs. integrated dual solution.	Choose only if board layout constraints prevent PowerSSO-24 placement or channel isolation mandates separate packages.

Compared with TPS4H160-Q1 and VND7E025AJTR-E, the VND5E025AK-E uniquely delivers dual-channel integration, analog current sense per output, and automotive-grade transient immunity in one PowerSSO-24 package-reducing system-level complexity for BCM and lighting applications where channel density and analog diagnostics are critical.

FAQ

What is the maximum continuous output current per channel?

The VND5E025AK-E does not specify a fixed continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its current limitation is set at 60 A (typical) under short-circuit conditions, but sustained current must be derated based on junction temperature. At T_j = 150 °C and 13 V supply, the safe continuous current is approximately 12 A with 100 cm² copper area (per Figure 36), verified in datasheet Section 4.1.

How does off-state open-load detection work without external components?

During off-state, the device applies a small internal test current (~5 µA) through the output channel and measures resulting voltage. If the load is disconnected, the output floats to VCC, triggering detection. This function operates independently for each channel and requires no external resistors or comparators-detailed in Table 10 and Figure 14 of the datasheet.

Can the current sense pins be used with a shared external resistor?

Yes-asserting CS_DIS high disables both internal sense current sources, allowing external sense resistors to be shared across multiple VND5E025AK-E devices. The sense pin then functions as a standard analog output node. This configuration is validated in Section 3.4 and Figure 33, with recommended 10 kΩ pull-up for CS_DIS.

Is reverse battery protection built-in or externally implemented?

Reverse battery protection is not fully integrated-the device requires an external diode or resistor network on the GND pin (as shown in Figure 31 and Section 3.1) to block reverse current. The IC itself withstands −0.3 V on VCC and includes internal ESD structures, but GND line protection must be added per application requirements.
