The PMG85XPH is a MOSFET-based high-side power switch with a logic-level gate drive. It is used mainly to switch low-current loads when logic signals require the same voltage level as the load. It is a versatile switch that can be used in virtually any application that requires an isolated, low-current MOSFET switch.

The PMG85XPH is a power MOSFET that is formed by the integration of two individual MOSFET devices into a single device - a source follower and a dual-gate depletion-mode device. It is operated in a low impedance, high-side configuration. The source follower is operated as a transistor switch to block the power flow and isolate the circuit. The depletion-mode MOSFET is used to control the current flow in the circuit. The combination of these two devices provides a high-performance switch with low on-resistance and low gate capacitance.

The PMG85XPH is designed to work with operating supply voltages from 5V to 30V. The switch has an input voltage range of 0V to 5V, which allows the use of logic-level signals for operation. The minimum input current required for operation is about 5mA and the maximum output current is 5A. The on resistance of the device is typically 250mOhm at 5V, and rises as the supply voltage increases.

The PMG85XPH can be used in a variety of different applications. The device can be used to switch a low-current LED driver or a small motor. It can also be used to isolate or control the power supply for a remote controlled switch, sensors or other low-current devices. It is suitable for both digital and analog switching applications and can be used as a relay or a switch.

The working principle of the PMG85XPH is fairly simple. When the logic-level gate voltage is low, the channel of the source follower is opened, blocking the power flow. When the gate voltage is high, the channel of the depletion-mode MOSFET is opened, allowing current to flow through the device. The PMG85XPH is designed for maximum performance and efficiency in low-current applications. The device is protected from over current and overvoltage conditions and is designed for long-term reliability in industrial applications.

The PMG85XPH is a versatile device that can be used in a wide range of applications. It is easy to use, reliable and offers excellent performance. The device is well suited for switching low-current loads in automotive, industrial and consumer applications. The device is RoHS compliant and available in various package sizes.
