PMIC-Power Distribution Switches, Load Drivers

The VNQ690SP13TR is a power distribution switch IC that provides load protection and control features to safely manage power-system operation in automotive and consumer applications. It integrates an output low-side power switch with matching low-side driver, over-voltage protection, and undervoltage protection. The VNQ690SP13TR supports the automotive environment and is suitable for typical applications such as power management and door locking in cars.

Application Field

The VNQ690SP13TR is built to withstand harsh automotive environments. It is designed for applications that require low-side power control, including power management, door locking, and light control. This device also serves as a power switch in many consumer applications, such as power management in automotive navigation systems, radio and audio systems, and air conditioning.

Working Principle

The VNQ690SP13TR consists of two independent functional blocks: the low-side power switch and the low-side driver. The low-side power switch provides an on/off control for the load. The low-side driver is a voltage-clamp circuit that provides on/off control for the low-side power switch. This device also includes overvoltage and undervoltage protection circuits.

The low-side power switch is activated by providing a logic-level input signal to the Gate pin. If the Gate signal is high (5 V or higher), the low-side switch is in the ON state. If the Gate signal is low (0 V), the low-side switch is in the OFF state. This device also features overvoltage and undervoltage protection to prevent the load from being exposed to potentially damaging voltages.

In addition to providing two independent power-control sections, the VNQ690SP13TR also features automatic shutdown and latch-up protection. This device is also equipped with a built-in thermal protection circuit to further prevent damage to the device.

Conclusion

The VNQ690SP13TR is a low-side power-distribution switch IC that provides load protection and control features for automotive and consumer applications. It integrates an output low-side power switch with matching low-side driver, overvoltage protection, and undervoltage protection. This device is suitable for applications that require low-side power control, including power management, door locking, and light control.
