VNQ660SP-E - 36V Quad High-Side Solid State Relay | STMicroelectronics
MPN: VNQ660SP-E ✓ Hoạt độngVNQ660SP-E Tóm tắt
A high-side switch (also called a high-side driver or solid-state relay) is a semiconductor switch placed between the supply rail and the load, sourcing current rather than sinking it. Unlike a low-side switch (placed between the load and ground), a high-side topology allows ground-referenced loads, simplifies fault detection, and eliminates the need for chassis grounding. High-side drivers belong to the broader power-switch IC family within power-management semiconductors, commonly used in automotive body electronics, industrial automation, and programmable logic controllers.
Key features of the VNQ660SP-E include a 6 V to 36 V supply range, 40 mOhm on-state resistance per channel, 6 A continuous current rating, CMOS-compatible logic inputs, off-state open-load detection, undervoltage and overvoltage shutdown, overvoltage clamp, thermal shutdown, and current limitation. The exposed bottom pad of the PowerSO-10 package provides a low thermal resistance path, allowing reliable operation at high ambient conditions.
Architecturally, the VNQ660SP-E uses STMicroelectronics' proprietary VIPower M0-3 process, which co-integrates vertical power MOSFETs with CMOS control logic on a single die. This monolithic integration enables compact PCB designs while delivering built-in protection features typically requiring external circuitry in discrete solutions. The device also includes diagnostic feedback and protection functions that meet automotive-grade reliability expectations.
Typical applications include automotive body control modules, lighting drivers, solenoid and relay drivers, industrial PLC outputs, and home appliance controls. Its quad-channel configuration suits multi-load systems requiring independent switching of lamps, motors, valves, and resistive heaters from a single MCU.
When designing with this device, calculate power dissipation as P_D = I^2 x R_DS(on) per channel and ensure the exposed pad receives adequate copper area for thermal management. The off-state open-load detection requires specific load impedance thresholds; review the datasheet carefully when driving LED or low-current loads.

Ứng dụng tiêu biểu
VNQ660SP-E phù hợp cho 6 Áp dụngs: Automotive Body Control Modules, Automotive Lighting Drivers, Industrial PLC Discrete Outputs, Solenoid and Valve Driver, Home Appliance Control Boards, Relay Replacement in Multi-Channel Systems.
Automotive Body Control Modules
The VNQ660SP-E is ideal for automotive body control modules driving four independent resistive or inductive loads such as lamps, solenoids, and motors. With 6 A continuous per channel and a 6 V to 36 V supply range, it covers 12 V and 24 V automotive battery systems including load-dump transients. The integrated open-load detection, undervoltage/overvoltage shutdown, and thermal shutdown reduce external protection components. Place input pull-down resistors near the MCU GPIO pins and ensure the exposed pad has at least 1 square inch of copper pour to dissipate worst-case 4 x I^2 x R_DS(on) heat when all channels are active simultaneously.
Được đề xuất
Automotive Lighting Drivers
The VNQ660SP-E drives multiple automotive lighting channels - headlamps, tail lamps, turn signals, and interior lighting - from a single chip. Each channel's 6 A rating handles halogen or high-power LED loads with adequate margin, while the 40 mOhm RDS(on) minimizes voltage drop and thermal dissipation. CMOS-compatible inputs interface directly with 3.3 V or 5 V MCU GPIO without level shifters. The off-state open-load detection enables broken-filament diagnostics required by ISO 26262 functional-safety lighting systems, reducing warranty cost from undetected faults.

Industrial PLC Discrete Outputs
The VNQ660SP-E serves as a quad-channel high-side output driver for industrial PLC digital output modules, switching 24 V loads such as relay coils, solenoid valves, and indicator lamps. Its 36 V maximum supply rating tolerates typical 24 V industrial bus voltage excursions, and the integrated overvoltage clamp protects against inductive kickback from solenoids - eliminating external flyback diodes. The exposed PowerSO-10 pad delivers low thermal resistance suitable for DIN-rail enclosure operation at 70C ambient. This enables 4-output modules without thermal derating across the full industrial temperature range.
Được đề xuất
Solenoid and Valve Driver
The VNQ660SP-E drives four proportional or on/off solenoid valves in hydraulic and pneumatic control systems, where each channel's 6 A continuous and built-in flyback clamp handle the inductive switching of magnetic coils. CMOS inputs allow direct drive from 3.3 V MCU PWM outputs for proportional control, with the 40 mOhm RDS(on) minimizing heat dissipation at typical 1 to 2 A solenoid currents. The current limitation feature protects against valve coil short faults without blowing external fuses, increasing system uptime in industrial automation environments.
Được đề xuất
Home Appliance Control Boards
The VNQ660SP-E integrates four high-side switches for home appliance control boards such as washing machines, dishwashers, and induction cooktops, where it drives pumps, door locks, valves, and indicator LEDs. Its compact PowerSO-10 package fits space-constrained appliance PCBs while delivering 6 A per channel - sufficient for most appliance loads under 100 W. Built-in thermal shutdown protects against stalled-motor conditions common in appliance service, and the CMOS-compatible inputs interface directly with low-cost appliance MCUs. This reduces BOM cost and PCB area compared to discrete MOSFET designs.
Được đề xuất
Relay Replacement in Multi-Channel Systems
The VNQ660SP-E replaces electromechanical relays in multi-channel systems where reliability, silent operation, and long life are critical - such as HVAC controls, access control panels, and battery management systems. With no moving parts, it offers >10x the lifecycle of mechanical relays at millions of switching cycles, while consuming no holding current. The integrated diagnostic features detect open-load and short-circuit conditions in real time, enabling predictive maintenance. Each channel's CMOS input can be PWM-modulated for dimming or proportional control - capabilities electromechanical relays cannot provide.

Ghi chú thiết kế
Estimated: At full load with all four channels delivering 6 A simultaneously, total power dissipation is approximately P_D = 4 x I^2 x R_DS(on) = 4 x 6^2 x 0.04 = 5.76 W. The PowerSO-10 exposed pad must be soldered to a copper pour of at least 1 square inch on top and bottom PCB layers with thermal vias to keep junction temperature below 150C. Without proper thermal design, the device will enter thermal shutdown under sustained high-load conditions, disrupting output control.
Place 100 nF ceramic bypass capacitors as close as possible to the VCC pin (pin 7) to suppress supply transients from load-dump and inductive switching events. Connect the exposed bottom pad to a ground copper pour with multiple vias (at least 9 vias in a 3x3 grid) for low thermal resistance. Keep high-current output traces wide (>= 2 oz copper, 50 mil minimum) to avoid voltage drop that would reduce load voltage and increase trace heating.
Do not drive loads with continuous currents exceeding 6 A per channel without verifying the exposed-pad thermal path is sufficient - thermal shutdown will activate without warning. Do not apply input signals before VCC reaches 6 V, as undefined logic states may cause partial turn-on of outputs. The off-state open-load detection has a minimum load impedance threshold (refer to datasheet) - LED loads or low-current sensors may not be detected as present when connected.
Route input signals (IN1-IN4) away from output traces (OUT1-OUT4) and VCC to minimize capacitive coupling that could cause output switching glitches. Use a ground plane on layer 2 directly under the IC to provide shielding and thermal dissipation. If using PWM for dimming or proportional control, place a small RC filter (100 ohm + 1 nF) on each input to slow edge rates and reduce EMI. Keep trace lengths to inputs under 50 mm to prevent ringing.
