Product details

Overview

VND5025LAKTR-E from STMicroelectronics is a double-channel high-side driver IC with integrated analog current sense, designed for automotive resistive/inductive load control (e.g., headlights, HVAC actuators, LED lighting). It features 25 mΩ typical on-state resistance per channel, 60 A current limitation, 4.5–36 V operating supply range, and CMOS-compatible 3.0 V logic inputs.

For engineers reviewing the VND5025LAKTR-E datasheet, VND5025LAKTR-E pinout, VND5025LAKTR-E application, or VND5025LAKTR-E equivalent, key selection criteria include thermal shutdown behavior, proportional current sense accuracy across -40°C to 150°C, reverse battery protection implementation, and ISO 7637-2 transient immunity in 12 V/24 V vehicle systems.

Technical Context

This device uses ST's VIPower M0-5 technology to integrate two independent high-side power switches with active power limitation, thermal self-protection, and diagnostic feedback. Each channel delivers precise proportional current sense (K = 1450–5180 A/A) with <±10% drift over temperature and load current.

The architecture includes undervoltage shutdown (4.5 V threshold), overvoltage clamp (up to 52 V), loss-of-ground/VCC detection, and ESD protection (4 kV HBM on inputs). CS_DIS enables high-impedance mode on sense pins, supporting flexible system-level diagnostics and fault isolation.

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 at 52 V)
On-state resistance (per ch.)	25 mΩ typ @ 3 A, 25°C - enables low conduction loss and <1 W dissipation at 20 A continuous (with heatsinking)
Current limit (typ)	60 A - protects against short-circuit faults while sustaining brief in-rush currents for lamps and solenoids
Standby supply current	2 µA @ 13 V - ensures negligible battery drain during vehicle sleep mode
Current sense ratio	1450–5180 A/A (load-dependent) - provides scalable analog feedback for closed-loop current monitoring without external shunt
Thermal shutdown threshold	150°C - triggers automatic restart after cooling, enabling robust recovery from overload without MCU intervention
Input logic compatibility	3.0 V CMOS - interfaces directly with 3.3 V microcontrollers without level-shifting

Pinout & Package

Package: PowerSSO-24™ - thermally enhanced exposed-pad SO-24 package optimized for high-current automotive PCBs with low R_thj-case (1.35°C/W max).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Clamped to 52 V internally; accepts 4.5–36 V nominal operation with ISO 7637-2 pulse immunity
GND	Ground reference	Must be protected externally against reverse battery via diode/resistor network per Figure 26
OUTPUT1, OUTPUT2	High-side power outputs	Drive loads connected to ground; each supports up to 60 A short-circuit current with thermal foldback
INPUT1, INPUT2	CMOS-compatible control inputs	3.0 V logic threshold with 0.25 V hysteresis; tolerant of ±1 mA DC current
CURRENT SENSE1, CURRENT SENSE2	Analog current feedback outputs	Deliver I_SENSE = I_OUT/K; K varies with load (1450–5180); leakage <1 µA when disabled
CS_DIS	Current sense enable/disable	Active-high CMOS input; drives sense pins to high-Z when high, enabling multiplexed sensing or fault masking

Key Features

Feature	Design Value
In-rush current management	Active power limitation prevents thermal runaway during lamp filament cold-start surges
Proportional analog current sense	Factory-trimmed K-ratio with <±10% drift over -40°C to 150°C enables accurate real-time load monitoring
Reverse battery protection support	Integrated GND protection network interface (Figure 26) allows robust implementation without additional ICs
EMC-optimized switching	Controlled dV/dt slopes (Figures 21–22) and layout-optimized PowerSSO-24™ package reduce radiated emissions
Diagnostic status signaling	Thermal shutdown indication via elevated sense voltage (V_SENSEH = 9 V) and current (I_SENSEH = 8 mA)

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	Single-channel, 160 mΩ R_ON, no analog current sense, SPI-configurable diagnostics	Suited for lower-current (<5 A), digitally managed systems requiring programmable fault response	Select when digital configuration and smaller footprint outweigh need for analog sensing and dual-channel integration
BD7F200GUL	Single-channel, 20 mΩ R_ON, 30 A ILIM, no thermal shutdown auto-restart, no reverse battery support	Targeted at consumer-grade industrial controls lacking automotive transient requirements	Choose only for non-automotive 12 V systems where ISO 7637-2 immunity and reverse-battery protection are not required

Compared with TPS4H160-Q1 and BD7F200GUL, the VND5025LAKTR-E uniquely combines dual-channel integration, factory-calibrated analog current sense, thermal auto-restart, and full automotive qualification-including reverse battery handling-making it optimal for cost-sensitive, safety-critical body electronics.

FAQ

What is the maximum safe continuous output current per channel?

The VND5025LAKTR-E does not specify a fixed continuous current rating due to thermal dependence on PCB copper area and airflow. With 100 cm² of 2 oz copper on top/bottom layers in free air, sustained 20 A per channel is achievable before thermal shutdown activates. Derating curves in Figure 29 and Table 15 must be used for precise thermal design.

How is reverse battery protection implemented?

Reverse battery protection requires external components per Figure 26: either a series resistor (R_GND) or Schottky diode (D_GND) in the GND path. The IC itself tolerates -0.3 V on VCC but not reverse polarity at GND; the external network limits reverse current to <200 mA, preventing damage to internal structures.

Can the current sense pins be used without external pull-up resistors?

No. CURRENT SENSE1/2 are open-collector current-output pins requiring an external pull-up resistor (typically 3.9 kΩ to VCC) to convert I_SENSE into a measurable voltage. Without it, the sense node floats and yields invalid readings; leakage remains <1 µA when CS_DIS is high, but no defined voltage is generated.

Does the device meet ISO 7637-2 Pulse 5a (load dump) requirements?

Yes-the internal VCC clamp limits voltage to 52 V under ISO 7637-2 Pulse 5a (75 V, 400 ms) conditions when used with recommended external TVS (e.g., SMAJ24A) and RC snubber per Section 3.2. The clamp energy absorption capability is validated up to 109 mJ (Table 4, E_MAX).
