Product details

Overview

VND5012AKTR-E from STMicroelectronics is a double-channel high-side driver IC with integrated analog current sense, designed for automotive resistive/inductive load control. It features 12 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. Used in body control modules for headlight, fog lamp, and HVAC blower actuation.

For engineers reviewing the VND5012AKTR-E datasheet, VND5012AKTR-E pinout, VND5012AKTR-E application, or VND5012AKTR-E equivalent, key selection criteria include thermal shutdown behavior, proportional current sense accuracy across -40°C to 150°C, reverse battery protection implementation, and ISO7637 transient compliance in 12 V/24 V automotive systems.

Technical Context

The device integrates two independent VIPower M0-5 high-side switches with active power limitation during inrush, self-limiting fast thermal transients, and output stuck-to-VCC detection. Each channel delivers precise proportional current sense (K₀ = 2780–8390) with <±8% drift over full temperature/load range when CS_DIS is low.

Protections include undervoltage shutdown (4.5 V threshold), overvoltage clamp (41–52 V), thermal shutdown at 150–200 °C with 7 °C hysteresis, and reverse battery tolerance via external GND network. Diagnostic outputs provide real-time status for short-circuit, overtemperature, and open-load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load dump transients per ISO7637-2 pulse 5a without external clamping.
Operating voltage range	4.5 V to 36 V - supports cold-crank (4.5 V) and 24 V commercial vehicle operation.
On-state resistance	12 mΩ (typ, 25°C) - limits conduction loss to ≤0.3 W at 5 A, enabling compact thermal design.
Current limitation	60 A (typ) - sustains short-circuit events while limiting junction temperature rise.
Standby current	2 µA (typ) - enables always-on functions without battery drain in sleep mode.
Current sense ratio	K₁ = 3590–6630 (5 A, -40°C to 150°C) - enables ±5% current measurement accuracy with 3.9 kΩ sense resistor.
Thermal shutdown	150 °C activation, 135 °C reset - provides automatic recovery after fault clearance without MCU intervention.

Pinout & Package

Delivered in PowerSSO-24 package: thermally enhanced exposed die pad (TAB = VCC), 24-pin surface-mount with dual-channel symmetry and dedicated diagnostic pins.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; internal clamp protects against 41–52 V spikes; TAB connected internally.
GND	Ground reference	Must be reverse-battery protected externally (diode/resistor network per Figure 26).
INPUT1/2	CMOS logic control	3.0 V compatible; 0.9 V/2.1 V thresholds with 0.25 V hysteresis for noise immunity.
OUTPUT1/2	High-side power output	Drives loads connected to ground; includes VCC diode (VF = 0.7 V @ 8 A, 150°C) for reverse polarity.
CURRENT SENSE1/2	Analog current monitor	Sinks current proportional to load (I_SENSE = I_OUT/K); max 5 V output with 1 µA leakage.
CS_DIS	Current sense enable	Active-high CMOS input; disables sense output (high-Z) when driven >2.1 V.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage sag during cold-crank startup of high-inertia loads like radiator fans.
Proportional current sense	Calibrated K-ratio (3590–6630) enables direct microcontroller ADC reading without external amplification.
Reverse battery protection	Supported via external GND-line diode/resistor network (Figure 26), eliminating need for series FET in battery path.
ISO7637-2 transient immunity	Withstands pulse 5a (load dump) up to 41 V without external TVS, reducing BOM count and PCB area.
Thermal shutdown with auto-restart	Enables fail-safe operation in sealed enclosures: recovers autonomously once T_j drops below 135 °C.

Applications

Headlight Control Module

HVAC Blower Driver

Use Scenario: PWM-controlled halogen/Xenon headlight dimming with real-time current monitoring for filament break detection.

IC Role / Device Role / Timing Role: High-side switch with analog current sense providing closed-loop feedback to MCU for adaptive brightness regulation.

Use Value: Eliminates discrete sense resistor and op-amp; ±5% current accuracy enables reliable open-circuit diagnosis before bulb failure.

Use Scenario: Variable-speed DC blower motor control in automotive climate systems with stall detection.

IC Role / Device Role / Timing Role: Dual-channel driver powering motor windings and auxiliary heater elements with synchronized diagnostics.

Use Value: Integrated 60 A current limit prevents MOSFET destruction during rotor lock; thermal hysteresis avoids oscillation during sustained overload.

Front Fog Lamp Actuation

Seat Heater Power Distribution

Use Scenario: High-current (30–40 A) fog lamp switching with inrush suppression and short-circuit logging.

IC Role / Device Role / Timing Role: Single-channel high-side driver managing peak inrush (≥10× rated current) during cold filament turn-on.

Use Value: Active power limitation reduces peak current to <60 A, preventing fuse nuisance blowing and contact welding.

Use Scenario: Redundant heating element control with independent current monitoring per zone (leg/back).

IC Role / Device Role / Timing Role: Dual-channel driver delivering isolated 15 A per seat zone with simultaneous current sense for thermal derating.

Use Value: On-die current sense enables zone-specific derating (e.g., reduce back zone if leg zone exceeds 12 A), meeting ASIL-B functional safety goals.

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 integrated current sense, SPI interface	Lacks analog current monitoring; requires external ADC and sense resistor	Select when digital diagnostics and programmable fault response outweigh need for analog sensing.
VND7050AJTR-E	Single-channel, 50 mΩ R_ON, 5 A continuous, built-in current sense (K=3000)	Lower current rating and power capability; suited for smaller solenoids and valves	Choose for cost-sensitive, lower-power body electronics where 5 A rating suffices.

Compared with VND5012AKTR-E, TPS4H160-Q1 trades analog sensing for configurability and higher channel count per package, while VND7050AJTR-E offers lower R_ON but sacrifices current capacity and thermal robustness needed for 60 A automotive loads.

FAQ

What is the maximum safe continuous current per channel?

The VND5012AKTR-E supports 12 A continuous current per channel at T_case = 85 °C with adequate PCB copper area (≥200 cm² per channel, per Figure 29). At 25 °C ambient with 100 cm² copper, derating to 8 A ensures junction temperature remains below 150 °C under worst-case conduction and switching losses.

How does the current sense function behave when CS_DIS is high?

When CS_DIS is driven above 2.1 V, the CURRENT SENSE pin enters high-impedance state (leakage ≤1 µA), disconnecting the internal sense transistor. This eliminates loading on external monitoring circuitry and prevents false readings during standby or diagnostic isolation.

Can this device drive inductive loads without external flyback diodes?

No external flyback diode is required: the integrated VCC clamp (41–52 V) and output V_F diode (0.7 V @ 8 A) safely dissipate demagnetization energy up to 508 mJ (L = 1.25 mH, V_bat = 13.5 V). External diodes remain recommended for >6 mH inductances per Figure 27.

What is the minimum input voltage required to guarantee turn-on?

The guaranteed turn-on threshold is 2.1 V (VIH min), with 0.25 V hysteresis ensuring noise immunity. Below 1.85 V, the output remains off; above 2.35 V, it latches on. This 3.0 V CMOS compatibility allows direct interfacing with 3.3 V MCUs without level-shifting.
