This document introduces practical aspects of using PowerMOS transistors to drive inductive loads, including application scenarios, circuit principles, and characteristic analysis.
This document provides a guide on the practical application of PowerMOS transistors as switches for inductive loads, such as solenoids and relays. It details the circuit states involved, including the 'off' state leakage, the 'on' state conduction, and the switching transitions.
The device requires a maximum of 115nC of gate charge to transition from off to fully on.
With a 1.0mA drive, the transition would take less than 115 µs.
The calculations assume a junction temperature of 175oC to verify suitability.
