VND7050AJTR 概要
A high-side driver is a power management IC that switches power to a load connected to ground, commonly used in automotive body control modules, industrial PLCs, and lighting systems. It integrates the power MOSFET, protection circuitry, and diagnostic feedback into a single package, simplifying PCB design and improving reliability. High-side drivers are part of the broader power management IC family, which includes low-side drivers, half-bridge drivers, and full-bridge drivers. The VND7050AJTR belongs to the VIPower M0-5 technology family, which is known for its low quiescent current and advanced protection features.
Key features of the VND7050AJTR include a very low standby current of 0.5uA (typical) when disabled, which is critical for battery-powered automotive applications. The device also provides a diagnostic output that indicates open-load, short-to-ground, and overtemperature conditions. The PowerSSO-16 package offers excellent thermal performance with a thermal resistance of 40C/W (junction-to-ambient), enabling high-current operation without external heatsinks in many applications. The driver is AEC-Q100 qualified, ensuring reliability in harsh automotive environments.
Technically, the VND7050AJTR uses a vertical N-channel power MOSFET architecture with a charge pump to drive the high-side switch. The charge pump allows the device to operate with a low input voltage while maintaining a low on-resistance. The device includes a current sense output that provides a proportional current signal for load monitoring, enabling precise control and diagnostics. The protection circuitry includes overvoltage clamping, reverse battery protection (with external resistor), and thermal shutdown with automatic restart.
Typical applications include automotive body control modules for driving exterior lights, interior lighting, and DC motors; industrial PLCs for controlling solenoids and relays; and general-purpose power switching in 12V/24V systems. The VND7050AJTR is also suitable for driving resistive, capacitive, and inductive loads, making it a versatile choice for many power switching applications.
When designing with this device, ensure adequate PCB copper area for thermal dissipation, especially when driving high currents. The diagnostic output should be connected to a microcontroller input with a pull-up resistor. For inductive loads, an external freewheeling diode is recommended to clamp voltage spikes during turn-off.

主な差別化要因
- Dual-channel configuration with 70mOhm on-resistance （vs VNQ7050AJTR-E)

- Very low standby current of 0.5uA （vs MC10XS3412 (NXP))
設計ノート
The VND7050AJTR has a thermal resistance of 40C/W (junction-to-ambient). At 9A per channel with 70mOhm on-resistance, each channel dissipates approximately 5.7W (I^2 * R). For dual-channel operation, total dissipation can reach 11.4W, resulting in a junction temperature rise of 456C above ambient, which is not acceptable. Therefore, ensure adequate PCB copper area and consider external heatsinking or forced air cooling for high-current applications. For typical automotive loads (e.g., 2A per channel), dissipation is only 0.28W per channel, which is manageable without external heatsinks.
Place the VND7050AJTR close to the load to minimize trace resistance and inductance. Use wide copper traces for the VBB and OUT pins to handle high currents and reduce voltage drop. Connect the exposed pad (if present) to a large copper area for thermal dissipation. Decouple the VBB pin with a 100nF ceramic capacitor and a 10uF electrolytic capacitor close to the device. The logic supply (VCC) should be decoupled with a 100nF capacitor. Ensure the GND pins are connected to a solid ground plane.
For inductive loads (motors, solenoids, relays), always connect an external freewheeling diode across the load to clamp voltage spikes during turn-off. Without this diode, the high-side driver can be damaged by the inductive kickback. Additionally, the diagnostic outputs are open-drain and require external pull-up resistors to VCC. Do not exceed the absolute maximum ratings, especially the supply voltage (28V) and output current (14A limitation). Ensure the enable inputs are not left floating; use pull-up or pull-down resistors as needed.
