VND810SPTR-E is an integrated power management device that belongs to the category of PMIC – Power Distribution Switches, Load Drivers. It is the perfect choice for applications demanding optimal power management solution, specifically those like automotive or home appliances.

Device Overview

The device bas been designed to provide a low RDS(on) and wide range of gate drive VCC voltage support, VNO to 8V with a maximum number of pins to 8pins. It also has an operating temperature range of -40°C to 85°C. In addition, it has an integrated ESD protection with 2-kV rating and Under Voltage Lockout (UVLO) with reset signal for powering up by total system control. These features make it ideal for a wide range of applications.

System Benefits

The VND810SPTR-E is the optimal choice for certain applications due to its multitude of benefits. It ensures best-in-class system performance. On-Resistance for all N-channels are 75mΩ (25V VG), 60mΩ (100V VG) thus minimizing switching power losses and improving power-efficiency. Moreover, the high current level and wide VCC range ensures high and reliable performance. Apart from this, high dV/dt minimizes switching noise. Additionally, its UVLO feature adds fail-safe protection by preventing high losses and damage to other components in the system. Finally, integrated ESD protection provides high-voltage pulse protection up to 2kV.

Application Field and Working Principle

The VND810SPTR-E is optimized for a variety of applications including medical, telecommunication, consumer and automotive. For consumer-related applications like televisions and audio equipment, it is used for the power distribution switch, load drivers, and constant current sources. Similarly, in automotive electronics, it is used to provide ignition protection in starter circuit, motor control, and voltage protection.

The device’s working principle is fairly straightforward. It switches the equivalent of a single transistor, using an external driver. The external driver supplies the device with the required input power and it, in turn, uses the combination of an internal logic and the driver to control the voltage and current level. Depending on the type of application, the output voltage and current can be regulated by a base resistor and/or a base current limiter. This allows for simple and efficient control of the power supply.

Conclusion

To conclude, VND810SPTR-E is an integrated power management device that is ideal for certain applications such as automotive or home appliances. It offers excellent system performance, high current level and wide VCC range which ensures the high and reliable performance. It also has an integrated ESD protection with 2kV rating and Under Voltage Lockout (UVLO) with reset signal for power up by total system control.
