Product overview

Description

The STGAP4S is a galvanically isolated single gate driver for IGBTs and SiC MOSFETs with advanced protection, configuration and diagnostic features. The architecture of the STGAP4S isolates the channel gate driving from the control and the low voltage interface circuitry through true galvanic isolation.

The unique output architecture is designed to allow the use of an external MOSFET push-pull stage giving flexibility in terms of current capability dimensioning and easing the use of several power switches in parallel. The 2 pre-driver outputs are characterized by current capability and output voltage swing optimized for that topology and allow the use of a negative gate driving supply.

The integrated controller for isolated flyback power supply allows to generate positive and negative gate driver supply voltages with few external components, enabling PCB space saving.

Protection functions such as the Miller clamp driver, desaturation and overcurrent detection, UVLO and OVLO are included to easily design high reliability systems.

A temperature sensor is integrated in the driver.

Open drain diagnostic outputs are present and detailed device conditions can be monitored through the SPI. Each function’s parameter can be programmed via the SPI, making the device very flexible and allowing it to fit in a wide range of applications.
