Operation and Working Principle

The DS38EP100-EVKH’s working principle focuses on the efficient control of its MOSFET drivers. Its MOSFET drivers consist of a totem-pole power partner pair, with each device consisting of two MOSFETs operating in parallel to provide twice the available current capability.

The MOSFET drivers and current controller are driven by the PWM control signal. The PWM control signal is used to drive the MOSFET drivers to produce the desired level of output voltage and current. The voltage regulator circuit ensures that the voltage output of the power supply is within the specified range. The power-ok and fault reporting features protect the power supply from any catastrophic events, thereby extending its lifetime.

The DS38EP100-EVKH also features a low power sleep mode, which enables the system to enter a low power state when not in use. This sleep mode helps to conserve energy and reduce heat. Additionally, the DS38EP100-EVKH features multiple thermal protection mechanisms that shut down the power supply if the supply temperature exceeds a certain threshold.

The DS38EP100-EVKH is a versatile tool for configuring and testing the performance of the DS38EP100 and DS38EP100X MOSFET drivers for general motor control and power supply applications. It provides an easy and effective way to evaluate and configure the different components of the motor drive and power supply systems.
