The TPS27081ADDCR is a high-side Load Switch features industry-standard ESD protection on all pins providing better ESD compatibility with other on board components. The TPS27081A level shifts ON/OFF logic signal to VIN levels and supports as low as 1-V CPU or MCU logic to control higher voltage power supplies without requiring an external level-shifter. Switching a large value output capacitor CL through a fast ON/OFF logic signal may result in an excessive inrush current. To control the load inrush current, connect a resistor R2 and add an external capacitor C1 as shown in the Simplified Schematic in the Technical Data Sheet. To configure the TPS27081A to achieve a specific slew rate, refer to the Application and Implementation section. A single pull-up resistor R1 is required in standby power switch applications. In such applications connect the R2 pin of the TPS27081A to the system ground when inrush current control is not required.

• Adjustable turn-on and turnoff slew rate control through external R1, R2 and C1
• Supports a wide range of 1.2 to 8V supply inputs
• Integrated NMOS for PFET control
• Full ESD protection (all pins)
• Low ON-resistance, high-current PFET
• Ultralow leakage current in standby (typical 100nA)

The VND600SP-E is a monolithic 2-channel high side Solid State Relay intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes. Built-in thermal shutdown and outputs current limitation protect the chip from over temperature and short circuit. Device turns-off in case of ground pin disconnections.
