VN808CM 개요
A high-side driver is a type of power switch that sits between the supply rail and the load, controlling current flow by switching the positive (high) side rather than the low side. In the broader semiconductor taxonomy, a high-side driver belongs to the smart power switch / power management IC family, sitting alongside low-side drivers, H-bridges, and solid-state relays. Eight-channel parts like the VN808CM are particularly valued where PCB real estate is tight and many discrete FETs would otherwise occupy valuable board area.
Key features of the VN808CM include 700 mA continuous output current per channel (1 A on the -32-E variant), CMOS-compatible input thresholds, very low standby current, compliance with IEC 61000-4-4/4-5 EMC immunity standards, and full RoHS compliance. Each channel is independently protected, so a fault on one output does not disable the other seven. The exposed bottom pad of the PowerSO-36 package keeps junction-to-ambient thermal resistance low enough to dissipate multi-channel loads from a single exposed-pad footprint.
The VIPower M0-3 process combines a vertical DMOS output stage with CMOS logic on the same die, allowing the protection circuitry to act on the same silicon that carries the load current. This co-integration is what enables the very fast shorted-load and over-temperature response that discrete FET designs cannot match without external comparators and sense resistors.
Typical applications include automotive body controllers (driving lamps, solenoids, and relays), PLC digital outputs, industrial actuator drivers, and any multi-load system where eight ground-referenced loads must be switched independently from logic-level signals. The device is also widely deployed in HVAC control boards and building automation panels.
When designing with this part, ensure that the exposed bottom pad is soldered to a sufficiently large copper pour (typically 1 square inch or more) to keep junction temperature within rated limits when multiple channels are simultaneously driving heavy loads. Per-channel thermal independence means the case-temperature sensor trips only on overall package heating, not per-channel, so system-level derating should account for worst-case cumulative dissipation.

일반적인 애플리케이션
VN808CM 적합 용도: 7 애플리케이션s: Automotive Body Control Module (BCM), PLC Digital Output Module, HVAC Control Board, Building Automation Relay Driver, Industrial Actuator Array, Home Appliance Control Board, Vending Machine Output Stage.
Automotive Body Control Module (BCM)
The VN808CM is purpose-built for automotive body controllers, where it drives eight independent ground-referenced loads such as tail lamps, turn indicators, door lock solenoids, and relay coils from a single compact IC. Its 700 mA per-channel continuous current (1 A on the VN808CM-32-E) covers nearly all BCM output stages without paralleling channels, while the integrated shorted-load and over-temperature protection is essential for surviving the harsh underhood and door-panel electrical environment. Per the ST datasheet, the VIPower M0-3 active current limit clamps the cold-filament inrush of incandescent lamps within the output SOA, eliminating the need for external inrush resistors. Compliance with IEC 61000-4-4 (burst) and IEC 61000-4-5 (surge) EMC immunity lets BCM designers pass automotive EMI tests without additional protection components on every output.

PLC Digital Output Module
Industrial PLC digital output cards use eight-channel high-side drivers like the VN808CM to switch 24 V field-side loads such as solenoid valves, indicator lamps, and small contactors. Each channel's CMOS-compatible input interfaces directly to the PLC's 3.3 V or 5 V logic buffer, removing the need for optocouplers or level shifters. The VN808CM's active current limitation protects the module when a field wiring short drives the output into a sustained overcurrent condition, and the case over-temperature sensor trips the entire card if multiple channels simultaneously drive near-maximum loads. The exposed bottom pad of the PowerSO-36 package bonds to the PLC card's copper pour to keep junction temperatures within industrial -40 C to +85 C ratings during sustained multi-channel switching.

HVAC Control Board
Heating, ventilation, and air-conditioning control boards use the VN808CM to switch 24 VAC relays, fan speed taps, and damper actuators from a single octal high-side device. The CMOS 3.3 V input threshold lets the MCU drive each channel directly without driver transistors, reducing BOM cost on high-volume HVAC units. The undervoltage shutdown feature prevents partial-actuation glitches during compressor inrush sags, while the loss-of-ground protection is critical in HVAC equipment where chassis ground can be lost during service. The PowerSO-36 package's exposed bottom pad allows the control board to dissipate the cumulative eight-channel heat without a separate heatsink, keeping the BOM compact for wall-mount thermostat enclosures.
추천
Building Automation Relay Driver
Building automation systems deploy the VN808CM to drive banks of latching relays that switch lighting circuits, motorized blinds, and HVAC zone valves from a centralized control panel. Eight channels per chip allows a compact DIN-rail module to control a full lighting zone or a multi-zone HVAC group without stacking multiple smaller drivers. The very low standby current of the VN808CM minimizes quiescent drain across thousands of installed modules, which is critical for energy-conscious building certifications. Per the datasheet, the case over-temperature sensor provides thermal independence between channels - meaning a single relay failure cannot cascade into a thermal shutdown of unrelated zones, improving building-wide reliability.

Industrial Actuator Array
Multi-axis industrial actuator arrays and small robotic platforms use the VN808CM to switch solenoid-driven pneumatic valves, indicator LEDs, and auxiliary relays from a single master controller. The eight independent channels with integrated protection mean that a shorted solenoid coil on one axis does not interrupt the other seven, keeping partial-failure modes safe in factory automation. The active current limitation combined with automatic restart handles the inrush of solenoid valves and motor contactors, while the IEC 61000-4-4/4-5 EMC compliance ensures the array passes the strict EMI requirements of industrial machinery directives. The exposed bottom pad of the PowerSO-36 package can be bonded to a chassis metal plate for additional heat extraction in enclosed actuator cabinets.

Home Appliance Control Board
Washing machines, dishwashers, and induction cooktops deploy the VN808CM to switch motor relays, water valve solenoids, door locks, and indicator LEDs from a single octal high-side driver. The CMOS 3.3 V input threshold interfaces directly to the appliance's main MCU without external driver transistors, simplifying the BOM and reducing PCB area. The integrated shorted-load and over-temperature protection is essential for surviving the wet, vibration-rich environment of laundry and kitchen appliances. The PowerSO-36 package's exposed bottom pad bonds to the appliance chassis or a large copper pour, keeping junction temperatures low enough for the typical 100,000-cycle appliance warranty without active cooling.
추천
Vending Machine Output Stage
Vending and kiosk machines use the VN808CM to switch refrigeration compressors, illumination LEDs, payment-system indicator lamps, and dispensing motors from a single octal high-side switch. The eight channels cover nearly all switched loads in a typical vending machine without additional driver ICs, reducing both PCB area and assembly cost. The very low standby current is critical for unattended kiosks where energy consumption directly affects operating margins. The exposed bottom pad of the PowerSO-36 package dissipates the cumulative eight-channel heat to the vending machine's metal chassis, eliminating the need for a dedicated heatsink in the confined interior space.

설계 노트
The PowerSO-36 package relies on its exposed bottom pad for both electrical substrate connection and primary thermal dissipation. Solder the pad to a copper pour of at least 1 square inch (6.45 cm^2) on the top layer, with thermal vias to inner copper planes for additional heat extraction. Estimated: with all eight channels simultaneously driving 500 mA each into 24 V loads, package dissipation approaches 4 W; without the bottom-pad copper pour, junction temperature would exceed 150 C in typical indoor ambient. The case over-temperature sensor provides thermal independence between channels but trips only on package-level heating, so system derating must account for worst-case cumulative multi-channel dissipation.
Place 100 nF decoupling capacitors as close as possible to each VS pin and to the VCC logic supply pin to suppress switching transients from the high-side MOSFET transitions. Use wide copper traces (>=0.5 mm per ampere of peak channel current) on all eight OUT pins to minimize voltage drop and heat concentration. Per the ST datasheet, the VS pins should be tied together on the PCB with a low-impedance plane; splitting VS between channels can cause uneven current sharing and false current-limit trips. Add a reverse-battery protection diode or P-channel FET on the VS supply rail if the application may experience reverse-polarity connection during service.
Do not leave the exposed bottom pad un-soldered - this will trigger thermal shutdown at well below rated current and may also cause erratic loss-of-ground detection. Do not drive the CMOS input pins above VCC + 0.3 V; the input structures are not 5 V tolerant on the logic side unless the datasheet version explicitly says so. When driving incandescent lamps, allow for 8-10x inrush at cold filament turn-on - the active current limit handles this, but system fuses must be sized to avoid nuisance trips during normal operation. Always reference the latest revision of the ST datasheet (vn808cm-e.pdf) for the precise current-limit threshold and timing values, which differ slightly between VN808CM-E (700 mA) and VN808CM-32-E (1 A) variants.
Route the eight input traces together as a logic-side bus, kept short and away from the high-current OUT traces to minimize capacitive coupling that could cause false channel triggers during fast VS transients. Star-ground the logic GND and power-stage return separately at the PCB level, joining them only at the VN808CM's GND pin to prevent ground bounce from corrupting CMOS input thresholds. Place a small RC filter (1 kohm + 100 pF) on each input if the MCU is more than 50 mm from the VN808CM to suppress ringing on long MCU-to-driver traces. Per ST layout guidance for VIPower M0-3 devices, keep the OUT traces physically short and wide enough to handle the peak current-limit value without significant resistive drop.
