HSA6880 Single Channel Isolated Gate Driver with Protection Features

PublishTime： 2021-12-17 Article Source：HUADA SEMICONDUCTOR

The HSA6880 is a single channel isolated gate driver with complete protection features by HUADA SEMICONDUCTOR. It can be used for fast-switching drive and protection of power IGBTs, Si and SiC MOSFETs.The driver incorporates galvanically isolated technology to enable 3.75 kVrms input-to-output isolation voltage and high transient immunity (50 kV/μs) as required in the industrial and automotive applications.

Its short propagation delay and small timingskew helps to achieve optimum performance at higher switching speeds when compared with other driver solutions available in the market. All logic pins are TTL compatible for easy interface to standard controllers and MCUs.

The HSA6880 architecture complete integrate protection features for protecting the devices in harsh environments. These integrated features include desaturation sensing with soft shutdown protection (also known as soft turn OFF), input-side and output-side undervoltage lockout (UVLO), active Miller current clamping and fault reporting.

The device supports bipolar and unipolar supply voltage configurations. In a bipolar configuration, the driver is typically supplied with voltages of +18V and -5V. For unipolar configuration, the driver is typically supplied with a positive 18 V (max 30 V).

The HSA6880 comes in a SOIC-16 wide-body package to meet UL isolation, creepage and clearance requirement.
