VN7004CLHTR 概要
A high-side switch (HSS) is a smart power switch that connects a load to the positive supply rail while providing protection, monitoring, and control functions beyond a simple MOSFET. The category sits in the power management IC hierarchy: high-side switch -> load driver -> smart power switch -> power management IC -> semiconductor. HSS devices combine a vertical power MOSFET with logic, gate drive, charge pump, current sensing, and protection circuits in one IC, eliminating discrete MOSFETs, gate drivers, sense resistors, and fuse/TVS protection networks.
Key features of the VN7004CLHTR include built-in load-current limitation, thermal shutdown with auto-restart, active load-dump clamp (compliant with ISO 7637 transients), undervoltage lockout, short-to-ground and short-to-Vbat detection, reverse-battery protection through the package tab, and an open-drain diagnostic status flag. The CurrentSense pin produces a ratiometric analog output that is multiplied by a KILIS factor into a known current for ADC sampling.
The OctaPAK 7+1 package exposes a large drain tab for direct PCB heatsinking, achieving a junction-to-ambient thermal resistance suitable for continuous 30-40 A operation on a properly designed copper area without an external heatsink. The 4 mΩ RDSon minimizes conduction losses compared to discrete N-MOSFET solutions, while integrated protection removes the need for external TVS diodes and self-resetting PTC fuses.
Typical automotive applications include driving halogen or LED headlamps, body control modules, door lock actuators, seat heaters, fuel pumps, and DC brushed motor loads. Industrial use extends to solenoid drivers and 24 V/36 V bus actuators when operating within SOA limits.
When designing, ensure the exposed pad has at least 6 cm² of top-side copper tied to the load supply and that the CurrentSense ground return shares the same net as the MCU's ADC ground reference. Always honor the published SOA curve for pulsed inrush loads such as cold lamp filaments.

主な用途
VN7004CLHTR の用途: 6 件s: Automotive Headlamp and Lighting Driver, Body Control Module (BCM) Load Driver, DC Brushed Motor and Solenoid Driver, Industrial 24 V Solenoid and Valve Driver, Automotive Fuel Pump and Oil Pump Driver, Battery-Buffered LED Lighting Strip.
Automotive Headlamp and Lighting Driver
The VN7004CLHTR drives halogen, HID, and high-power LED headlamps on the 12 V automotive battery bus with up to 80 A continuous load current and a 4 mΩ RDSon that limits conduction losses to roughly 3.2 W at full load. Its integrated load-dump clamp compliant with ISO 7637 and -1 protection lets it survive jump-start and alternator load-dump transients up to 28 V, replacing discrete MOSFETs, sense resistors, and PTC fuses. The CurrentSense analog feedback enables closed-loop LED thermal derating and lamp-out diagnostics via the BCM ADC. PWM dimming up to 1 kHz is supported; above that, thermal dissipation becomes the limiting factor. Compared to mechanical relays, this IC removes contact bounce, reduces EMI, and adds self-resetting protection.

Body Control Module (BCM) Load Driver
The VN7004CLHTR's 80 A rating, analog CurrentSense output, and OctaPAK 7+1 footprint make it ideal for BCM outputs driving seat heaters, window lifters, door lock actuators, and mirror adjusters. The integrated current limit at 135 A protects the harness during stall conditions such as a frozen window motor drawing locked-rotor current. Thermal shutdown with auto-restart prevents destructive overheating if a load fails short. Compared to a discrete N-MOSFET plus fuse, the IC provides accurate, repeatable, resettable protection that the BCM software can log for warranty diagnostics. The 4 mΩ RDSon keeps cold-crank voltage drop below 0.4 V at 100 A inrush, preserving actuator torque during engine start.
おすすめ
DC Brushed Motor and Solenoid Driver
For driving 12 V brushed DC motors and solenoids in pumps, valves, and HVAC actuators, the VN7004CLHTR provides high-side switching up to 80 A with 4 mΩ RDSon that minimizes voltage sag at the motor terminals. Its high-side topology keeps the motor frame isolated from battery ground during operation, reducing corrosion in underbody wet applications. The analog CurrentSense output allows the MCU to implement stall detection by sensing current rise when rotor locks. For PWM speed control below 1 kHz, the part switches cleanly; for higher-frequency PWM, an external freewheel diode is required because the body diode is not optimized for fast switching. Reverse-battery protection through the drain tab adds robustness during jump-start miswiring.
おすすめ
Industrial 24 V Solenoid and Valve Driver
Although optimized for 13 V automotive systems, the VN7004CLHTR tolerates 24 V industrial bus voltages up to its 28 V load-dump clamp ceiling, making it usable for solenoid and valve switching on factory automation PLC backplanes. At 24 V, RDSon rises slightly and continuous current must be derated per the SOA curve, but the integrated protections (current limit, thermal shutdown, reverse-battery) eliminate the discrete fuse + TVS + MOSFET stack. The analog CurrentSense output integrates directly with industrial ADC front-ends for closed-loop proportional solenoid control. For sustained 24 V/40 A applications, derate to 70% of the 13 V rating or choose the BTS50085-1TMA cross-brand alternative which is rated specifically for 24 V.
おすすめ
Automotive Fuel Pump and Oil Pump Driver
The VN7004CLHTR's 80 A continuous rating covers the inrush of brush-type fuel pumps during cold-start, where locked-rotor current can spike to 60-70 A before the rotor spins up. The 4 mΩ RDSon minimizes voltage drop on the 12 V battery feed, preserving pump torque during cranking when bus voltage sags to 8 V. Integrated current limit protects the wiring harness if the pump seizes. The CurrentSense analog output lets the ECU implement run-dry detection (current falls when fuel is low) and pump-speed closed-loop control via PWM duty adjustment. Compared to a relay + fuse, this IC adds diagnostic intelligence without increasing BOM cost beyond the relay footprint replacement.
おすすめ
Battery-Buffered LED Lighting Strip
For battery-buffered high-brightness LED lighting strips drawing up to 30 A, the VN7004CLHTR provides high-side switching with current-sense feedback to enable constant-current PWM dimming. At 4 mΩ RDSon, conduction loss is only 1.2 W at 30 A, which the OctaPAK 7+1 package dissipates easily on a 6 cm² copper pad. The CurrentSense output can be sampled by an LED driver MCU to detect open-LED or short-LED faults and report them over CAN. Compared to a discrete P-channel MOSFET, the active high-side drive has lower RDS(on) and eliminates the need for a charge pump or level shifter. The IC is suitable for both interior ambient lighting and exterior signature lighting.

主な差別化要因

- Analog CurrentSense diagnostic output integrated （vs VN751STR)
設計ノート
Estimated: at 80 A continuous and 4 mΩ RDSon, conduction loss is roughly 25.6 W. The OctaPAK 7+1 package requires at least 6 cm² of top-side copper tied to the drain tab to keep junction temperature rise below 100 °C at ambient 70 °C. Use 2 oz copper or add thermal vias to inner planes for additional spreading. Without proper heatsinking, thermal shutdown will engage at sustained >40 A loads.
Route the Vbat and OUT traces as wide as possible on both top and inner layers, using 2 oz copper minimum. Place the input bypass capacitor (typically 100 nF ceramic) directly between Vbat (pin 1) and GND (pin 4) within 5 mm trace length. The exposed pad (TAB) must be soldered to the PCB drain pour with an array of thermal vias; do not rely solely on top-side copper for heat dissipation.
Do not exceed the SOA curve published in the datasheet for pulsed loads such as cold-lamp filaments (10x nominal inrush for 10 ms). Reverse-battery protection depends on the drain tab connection — a floating tab defeats reverse-polarity robustness. The CurrentSense pin is a current source, not a voltage output: connect it to a sense resistor to GND and feed the resulting voltage to the MCU ADC.
The IN logic input is CMOS-compatible with internal pull-down. For PWM dimming up to 1 kHz, drive IN with a clean push-pull GPIO; do not leave IN floating during MCU reset (a floating IN can enable the output unpredictably). Add an RC filter (1 kΩ + 100 nF) on IN if the MCU GPIO traces pass near high-dV/dt OUT traces to prevent false triggering from capacitive coupling.
