Power Management Integrated Circuits (PMICs) are semiconductor devices that supply power to an electronic system. There are many different types of power management integrated circuits (PMICs) including, but not limited to, Power Distribution Switches, Load Drivers, Voltage Regulators, and Current Regulators. The VN06SP-E is a member of the Power Distribution Switches, Load Drivers PMIC family. This application note details the features and working principle of the VN06SP-E.

VN06SP-E is a dual channel, low side power switch with integrated high-side current regulation and load sense capability. It is designed to switch and regulate an inductive or non-inductive load to a 12V power supply. The integrated over-current and over temperature protection features aid in protecting the switch against external load faults.

The VN06SP-E has a peak output current capability of 6 Amps for each of the two channels. This peak output current is limited by an internal current sense resistor and an external current sense resistor. The current sense resistor is programmable from 0.1 Ohms to 1 Ohm and the external current sense resistor can be programmed from 0.01 Ohms to 0.1 Ohms. This allows the VN06SP-E to be used in both high current and low current applications.

The VN06SP-E also has an integrated MOSFET switch that can be used to control the output voltage of the device. This feature allows for a wide range of operating voltages for the VN06SP-E. The MOSFET switch can be configured from 2.7V to 14V. The device operates from a single 12V supply.

In addition to the features mentioned above, the VN06SP-E also has a load sense capability. This feature allows the device to sense the load current and regulate the output voltage accordingly. This helps to ensure the device is operating safely and reliably. It also helps to reduce the power consumption of the device.

The working principle of the VN06SP-E is relatively simple. The device consists of two MOSFETs and a current sense resistor in a half-bridge configuration. The output voltage is determined by the ratio of the MOSFET resistances and the current sense resistor. The MOSFETs are switched on and off in order to maintain the output voltage. The load sense feature is used to detect any changes in the load current, which is then used to control the output voltage.

Overall, the VN06SP-E is a versatile, power management integrated circuit that can be used in a wide range of applications, from small scale electronic systems to large scale industrial systems. Its features, such as its integrated MOSFET switch, current sense resistor, and load sense capability, make it ideal for use in power distribution systems. Its ability to operate from a single, 12V supply also makes it a convenient, cost-effective device.
