Product overview
Description
The DEMOTD350 demonstration board is an advanced gate driver for IGBTs and power MOSFETs.
Control and protection functions are included and allow the design of high reliability systems.
The device integrates a two-level turn-off feature with adjustable level and delay.
This function protects against overvoltage at turn-off in case of overcurrent or short-circuit conditions.
The same delay set in the two-level turn-off feature is applied at turn-on to prevent pulse width distortion.
The integrated active Miller clamp function avoids the need of negative gate drive in most applications and allows the use of a simple bootstrap supply for the high-side driver.
The IGBT desaturation protection and a FAULT status output are available.
The board is compatible with both pulse transformer and optocoupler input signals.
