Typical Applications
VNQ6008SA-E is suitable for 6 applications: Automotive Body Control Module, Industrial PLC Output Stage, LED Lighting Control, Relay and Solenoid Driver, Smart Power Distribution, Test and Measurement Equipment.
Automotive Body Control Module
The VNQ6008SA-E is ideal for automotive body control modules (BCMs) that need to drive multiple loads such as exterior lights, interior lights, and relays. Its 8 channels allow centralized control of various actuators, while the SPI interface enables diagnostics and fault management. The device's AEC-Q100 qualification ensures reliability in harsh automotive environments. In a typical BCM, the VNQ6008SA-E is placed between the microcontroller and the loads, with each channel driving a lamp or relay. The SPI bus connects to the MCU for control and status readback. The current sense output can be used to detect lamp failures or short circuits. The device's low standby current (5 µA) helps reduce battery drain when the vehicle is off. Thermal management is critical; the PowerSSO-36 package with exposed pad should be soldered to a large copper area to dissipate heat from multiple channels operating simultaneously.

Design Notes
The PowerSSO-36 package has a thermal resistance of 35 °C/W. For 8 channels each driving 1A at 12V, total power dissipation can be up to 8 * (1A^2 * 0.06Ω) = 0.48W, which is manageable. However, if driving inductive loads with high inrush currents, ensure adequate copper area on the PCB (at least 2 square inches) to keep junction temperature below 150°C.
Place a 100nF ceramic capacitor close to the VCC pin and a 10µF electrolytic capacitor for bulk decoupling. For SPI lines, keep traces short and add series resistors (e.g., 33Ω) to reduce ringing. The exposed pad should be soldered to a large ground plane for thermal and electrical connection.
Do not exceed the absolute maximum supply voltage of 60V. Ensure the SPI lines are not left floating; pull-up resistors on CSN and SCLK are recommended. When driving inductive loads, verify that the internal clamping diodes are sufficient for the load's energy; otherwise, add external flyback diodes.
