SMA6853MX

The SMA6853MX provides a highly-integrated solution by incorporating key components into one package – 500V/2.5A MOSFET in a 3-phase full-bridge configuration, built-in protection functions such as UVLO (undervoltage lockout) and TD (thermal detection) circuits, pre-driver ICs with 7.5 V regulator output, and bootstrap diodes with limiting resistors.
The product is capable of detecting overcurrent through three shunt resistors. And the package is fully-molded SIP.
