VNQ7004AYTR Overview
A high-side driver is a power management IC that connects a load to the positive supply rail, providing switching, protection, and diagnostic functions. It sits between the microcontroller and the load, translating low-voltage logic signals into high-current switching actions. In the power management hierarchy, a high-side driver is a type of power switch, which falls under power management ICs, which are part of the broader semiconductor category. This device integrates four such drivers in a single package, reducing board space and component count.
Key features include a very low standby current of 0.5 uA (typical) for battery preservation, a wide operating voltage range of 4V to 28V, and a maximum output current of 7A per channel (limited by package thermal capability). Each channel has overcurrent, overtemperature, and short-circuit protection, with a diagnostic output that reports fault conditions via a current-sense or digital feedback pin. The device is AEC-Q100 qualified, ensuring reliability for automotive applications.
The VNQ7004AYTR uses a vertical power MOSFET technology with an integrated charge pump for the high-side gate drive. This architecture allows for efficient switching with a typical on-resistance of 70 mOhm per channel, minimizing power dissipation. The device also features a dedicated current-sense output that can be used for load current monitoring, enabling precise control and fault detection in applications such as lighting, motors, and solenoids.
Typical applications include automotive body control modules, interior and exterior lighting, DC motor control, and industrial PLC outputs. The device's ability to drive inductive loads with built-in freewheeling protection makes it ideal for relay and solenoid replacement. Its diagnostic capabilities allow for real-time load monitoring, improving system reliability and enabling predictive maintenance.
When designing with this device, ensure adequate PCB copper area for thermal dissipation, as the PowerSSO-28 package relies on the exposed pad for heat transfer. The current-sense output should be connected to an ADC input for accurate load monitoring, and the enable pins should be controlled by the microcontroller with proper pull-down resistors to avoid unintended activation during power-up.

Key Differentiators
- Quad-channel integration in a single PowerSSO-28 package (vs VND7004AYTR (double channel))
- Analog current-sense output for simple diagnostics (vs VNQ7004SYTR (SPI interface))
- Very low standby current of 0.5 uA (vs VNQ7040AYTR (higher current))
Design Notes
The PowerSSO-28 package has an exposed pad that must be soldered to a large copper area on the PCB for effective heat dissipation. For continuous operation at high currents, ensure the PCB copper area is at least 1 square inch per channel. Use thermal vias to connect the exposed pad to inner and bottom layers. The thermal resistance (theta_JA) depends on PCB design; refer to the datasheet for typical values.
Place the input and output capacitors close to the VCC and OUT pins to minimize parasitic inductance. Use a 100 nF ceramic capacitor on the VCC pin and a 10 uF electrolytic capacitor for bulk storage. The current-sense output should be routed to an ADC input with a low-pass filter to reduce noise. Keep the sense trace short and away from high-current paths.
Do not exceed the absolute maximum supply voltage of 28V. Ensure the input pins are not left floating; use pull-down resistors to keep the outputs off during power-up. The current-sense output has a limited voltage range; do not connect it directly to a voltage source. For inductive loads, ensure the freewheeling protection is properly utilized by connecting the load between the output and ground.
